Description

  The present invention relates to a storage battery device for an electric vehicle such as a hybrid vehicle or an electric vehicle.

  2. Description of the Related Art In recent years, as vehicles other than engine vehicles that run only by an engine, hybrid vehicles that use both an engine and a motor as drive sources and electric vehicles that run by a motor are becoming widespread. Generally, an engine vehicle is equipped with an immobilizer system that does not allow engine start unless the ID code transmitted from the transponder in the vehicle key matches that on the vehicle side, thereby taking measures against vehicle theft. Therefore, it is necessary to take this kind of countermeasure also in a hybrid vehicle and an electric vehicle, and an example of the technique is disclosed in Patent Document 1, for example.

  By the way, in the case of a hybrid vehicle or an electric vehicle, a storage battery (equivalent to 288V) is mounted on the vehicle body, and the motor is driven using this as a drive source. By the way, since this kind of storage battery is expensive, when a thief steals in a vehicle, the possibility of using the storage battery instead of the vehicle itself as a target of theft cannot be denied. However, although Patent Document 1 describes prevention of theft of the vehicle, no mention is made of prevention of theft of the storage battery, and a countermeasure is required for preventing theft of the storage battery as well as prevention of theft of the battery.

Thus, Patent Document 2 discloses a technique for suppressing theft of a battery mounted on an electric vehicle. In this technology, a password is given to each of a vehicle body of an electric vehicle, a battery serving as a travel drive source, and a charger that charges the battery, and a motor start operation is performed as an engine system start operation of the electric vehicle. The motor start is permitted on condition that all these passwords match. If this technique is used, even if a thief steals a battery and transfers it to another vehicle, the vehicle cannot move because the motor does not operate because the password is not verified. Therefore, it is difficult for the battery to be seen as a theft object, and the battery theft prevention effect is enhanced.
JP 2003-320922 A JP 2001-78302 A

  However, the technique of Patent Document 2 requires that the three persons of the vehicle main body, the battery, and the charger have passwords, and at the time of password verification, a process of reading and comparing the passwords from these three persons is required. . Therefore, in this technology, in order to suppress battery theft, complicated processing such as password registration to the three parties, password reading from the three parties, and comparison thereof is required. Therefore, a technology that can prevent battery theft is desired.

  The objective of this invention is providing the storage battery apparatus of the electric vehicle which can perform this by a comparatively simple process, improving the antitheft effect of a storage battery.

In order to solve the above problems, in the present invention, in a storage battery device for an electric vehicle that runs on a power storage battery that can be charged and discharged, state value management means for managing a state value corresponding to the current use state of the storage battery; A determination means for determining whether or not the state value is within a use permission range of the storage battery, and if the state value exceeds the use permission range, it is determined that the battery is not under a charging condition by a regular user; Limiting means for restricting charging of the storage battery from the outside of the vehicle , the state value management means counts a usage period of a battery ID code which is a unique ID of the storage battery as the state value, and the determination means Determining whether or not the usage period of the battery ID code is within the expiration date as the usage-permitted range, and the limiting means limits the charging if the usage period exceeds the expiration date, A hybrid system for running the electric vehicle using a storage battery and an engine as a wheel drive source, an update means for executing an update operation of the expiration date of the battery ID code before the hybrid system enters a start-up operation, and a storage battery specific Storage means in which the first identification code is written, and as the update operation of the expiration date, the update means has a key-specific first identification code transmitted wirelessly by the first key for expiration date update. The expiration date is updated on the condition that the identification collation is established in agreement with the code string on the storage battery side, and the first key updates the expiration date separate from the vehicle operating system key. The gist of the present invention is that the dedicated key is a key that is not always carried .

  According to this configuration, when a thief who has stolen after removing the storage battery (storage battery device) from the electric vehicle performs charging of the stolen storage battery using, for example, an external charging device, Therefore, when charging is performed, charging limitation by the limiting unit works, and charging limitation such as charging cannot be performed. Therefore, if the charging operation is restricted for the stolen storage battery in this way, even if the storage battery is stolen from the electric vehicle, the stolen battery cannot be used as usual. It will kill the will of theft. Therefore, it is difficult for the storage battery to be stolen in the electric vehicle, and the storage battery can be made difficult to be stolen.

  In the charging restriction according to the present invention, the determination unit takes in the state value of the storage battery from the state value management unit and determines whether or not the state value is within a use permission range. This is a process for determining whether or not to limit the storage battery. Therefore, for example, when a password is registered in a plurality of parts related to charging and they do not all match, charging can be limited by a relatively simple process compared to a charging limiting process in which charging is not permitted. As described above, it is possible to perform this by a relatively simple process while enhancing the antitheft effect of the storage battery.

According to this structure, when the usage period exceeds the expiration date, the storage battery is in a state of being restricted with respect to charging. Therefore, even if the storage battery is stolen from the electric vehicle, the storage battery will be in a charge-restricted state after a while. Will be killed, and will greatly kill the thief's willingness to steal. In addition, if the usage period of the storage battery exceeds a certain time, it will be in a state where it cannot be charged freely, since the storage battery will not function as a storage battery part after that, this is highly effective in reducing the willingness of the storage battery, It is very effective in suppressing theft. In addition, even if an expiration date is given to the use of the storage battery, this expiration date can be renewed, so even if the storage battery has an expiration date and restricts free operation, if it is a regular user, By updating the expiration date, the storage battery can be used continuously.

According to this arrangement, by updating the expiration date of use of the storage battery, it is possible to continue using battery.

According to the structure of a call, the first key is for the expiration date update is because it is usually not necessary keys to carry, it is possible to keep a constantly this kind of key to the location where less likely to be stolen. Therefore, a situation in which the vehicle update key is stolen by a third party is unlikely to occur, which is effective in improving theft prevention.

  In the present invention, wireless communication is performed with the second key which is a vehicle operating system key, and the second identification code unique to the second key received at that time coincides with the code string on the electric vehicle side, and the identification verification is established. On the condition, the storage battery device of the electric vehicle connected to the wireless verification mechanism that permits the operation of the electric vehicle, wireless communication with the first key as a partner and wireless communication with the second key as a partner The gist is to share the wireless verification mechanism.

  According to this configuration, when operating the electric vehicle with the second key, the wireless verification mechanism provided in the electric vehicle performs wireless verification with the second key. Is also used when wirelessly communicating with an electric vehicle. Therefore, for example, the antenna system parts of the wireless verification mechanism are shared between the first key and the second key. Compared with the case where the antenna system parts are provided for each of these keys, the number of parts is reduced and the device size is reduced. Effects such as reduction can be obtained.

The gist of the present invention is that the wireless verification mechanism also performs identification verification of the first identification code acquired from the first key.
According to this configuration, when operating the electric vehicle with the second key, the wireless verification mechanism provided in the electric vehicle performs wireless verification with the second key. Wireless verification is also performed. Therefore, the wireless verification mechanism is shared between the first key and the second key, and there are effects such as a reduction in the number of parts and a reduction in the device size as compared with the case where a verification system component is provided for each key. can get.

In the present invention, the wireless verification mechanism permits the start of the wheel drive source of the electric vehicle if the identification verification with the second key is established, and the updating means includes the second key The gist of the invention is that when the hybrid system enters the start-up operation on condition that the identification verification is established, the battery ID code expiration date update operation is executed before the start-up operation .

  In the present invention, the update means captures the first identification code from the communication device through the connector portion in a state where the communication device to which the first key is connected is connected to the connector portion of the electric vehicle. The gist is to update the expiration date on condition that the identification collation is established in agreement with the code string on the storage battery side.

  According to this configuration, it is possible to update the expiration date of the storage battery not only by wireless communication using a key but also by wire using a communication device, so there are options for an update method when updating the expiration date of the storage battery. Even if the storage battery has a charging limit, the convenience of use is improved when the expiration date is updated.

The gist of the present invention is to permit both the renewal of the expiration date and the start of the wheel drive source if the identification verification is established between the first key and the electric vehicle.
According to this configuration, since it is possible to perform both the renewal of the storage battery expiration date and the start of the wheel drive source with the first key, it is not necessary to own a key for each of these functions, and the key carrying viewpoint The convenience is improved.

The gist of the present invention is that the storage battery control system component for managing the charging restriction is integrated into the storage battery.
According to this configuration, the storage battery control system component related to the charging restriction is incorporated into a large component called a storage battery. By the way, it is possible to eliminate the storage battery charge limiting function by replacing the storage battery control system parts, for example, but if the storage battery control system parts are incorporated into the storage battery as in the present invention, the storage battery control system parts are built in the large parts. Therefore, it becomes difficult to replace the storage battery control system parts, which is also highly effective in suppressing the theft of the rechargeable battery.

  In this invention, between the memory | storage means in which the 1st identification code peculiar to a storage battery was written, the communication means which can communicate between the server which manages the update of the said expiration date, and a server via the said communication means The server side update that updates the expiration date on the condition that the first identification code is communicated with the server and the first identification code on the electric vehicle side coincides with the code string on the server side and the identification collation is established. And a means.

  According to this configuration, even if an expiration date is given to the use of the storage battery, the expiration date can be renewed. If there is, the storage battery can be used continuously by updating the expiration date. Since the server manages the update of the expiration date, it is not necessary for the device necessary for the update to be stolen, and an invalid expiration date update is unlikely to occur.

  According to the present invention, this can be performed by a relatively simple process while enhancing the antitheft effect of the storage battery.

(First embodiment)
Hereinafter, a first embodiment of a storage battery device for an electric vehicle embodying the present invention will be described with reference to FIGS.

  As shown in FIG. 1, when the vehicle is a hybrid vehicle 1, a hybrid system 4 that travels using both the engine 2 and the motor 3 as wheel drive sources is mounted on the vehicle body. In the hybrid system 4, a mode in which the power of the engine is mechanically transmitted to the wheels, a mode in which the power is generated by the power of the engine and the motor is driven, a mode in which the wheels are directly driven by both the engine and the motor, The vehicle travels in various modes, in which the engine is stopped and the vehicle travels only with the motor. The hybrid vehicle 1 corresponds to an electric vehicle, and the engine 2 and the motor 3 constitute a wheel drive source.

  The hybrid vehicle 1 is equipped with a hands-free system 6 that permits door lock locking / unlocking and hybrid system activation without using a mechanical key if the portable device 5 is owned. The hybrid vehicle 1 is provided with a verification ECU 7 that performs ID verification in the hands-free system 6. The reference ECU 7 is connected to an outside LF transmitter 8 installed outside the vehicle, an inside LF transmitter 9 installed inside the vehicle, and an RF receiver 10 installed similarly inside the vehicle. The portable device 5 corresponds to a vehicle operation system key (second key), and the verification ECU 7 to the RF receiver 10 constitute a wireless verification mechanism.

  In addition, a door ECU 11 that controls door locking / unlocking / unlocking is connected to the verification ECU 7 via a bus 12 in the vehicle. The door ECU 11 is connected to a door lock motor 13 that serves as a drive source when the door lock is locked and unlocked. The door ECU 11 is connected to a door courtesy switch 14 that detects the open / closed state of the door. The door ECU 11 can input an open signal or a close signal from the door courtesy switch 14 to recognize whether the door is in an open state or a closed state.

  When the hybrid vehicle 1 is parked (when the hybrid system is stopped and the door is locked), the verification ECU 7 sends an LF band request signal Sreq as an ID reply request (request) from the outside LF transmitter 8 to open the communication area outside the vehicle. Form. Here, when there are a plurality of out-of-vehicle LF transmitters 8, these transmit the request signal Sreq one by one in order and repeat the transmission. When the portable device 5 enters the communication area outside the vehicle, the portable device 5 receives this request signal Sreq. When the portable device 5 recognizes that the LF signal is an ID reply request, the vehicle ID code (the first code registered in its own memory) 2 identification code) as a vehicle ID signal Sid in the RF band.

  The verification ECU 7 recognizes that communication outside the vehicle is established when the RF receiver 10 receives the vehicle ID signal Sid when the request signal Sreq is transmitted from the vehicle LF transmitter 8, and sets the vehicle ID code of the portable device 5 to the vehicle. As an ID collation to be compared with the code string registered in (1), the outside collation is performed. When the verification ECU 7 recognizes that the vehicle external verification has been established, the verification ECU 7 activates the touch sensor 15 in a stopped state, and when the touch sensor 15 detects a touch operation of the handle knob by the operator, the door ECU 11 receives a door unlock request signal. Is output. Upon receiving the door unlock request signal, the door ECU 11 drives the door lock motor 13 to release the locked door lock.

  On the other hand, when the hybrid vehicle 1 detects the pressing operation of the lock button 16 of the handle knob when the hybrid vehicle 1 is in the engine stopped state and the door lock is unlocked, the verification ECU 7 causes the vehicle exterior LF transmitter 8 to form the vehicle exterior communication area again. When the vehicle exterior verification is performed and the vehicle exterior verification is established, a door lock request signal is output to the door ECU 11. When the door ECU 11 receives the door lock request signal, the door ECU 11 drives the door lock motor 13 to lock the door lock.

  When the verification ECU 7 detects that the driver has boarded by the door courtesy switch 14, the verification ECU 7 transmits a request signal Sreq from the in-vehicle LF transmitter 9 to form a communication area in the vehicle. When the portable device 5 enters the in-vehicle communication area, the portable device 5 returns a vehicle ID signal Sid in response to the request signal Sreq. When the verification ECU 7 transmits the request signal Sreq from the in-vehicle LF transmitter 9, when the RF receiver 10 receives the vehicle ID signal Sid of the portable device 5, the verification ECU 7 recognizes that in-vehicle communication has been established, and the portable device in the vehicle. In-vehicle verification is performed as ID verification for comparing the vehicle ID code between the vehicle 5 and the vehicle, and the result of in-vehicle verification is recognized. This indoor verification may include immobilizer verification for verifying the transponder code embedded in the portable device 5 with the vehicle.

  A power supply ECU 17 that controls the power supply of various electrical components in the vehicle is connected to the verification ECU 7 through the bus 12. The power supply ECU 17 starts to be activated when the portable device 5 is half inserted into the key slot 18 beside the steering wheel, for example. The power supply ECU 17 is connected to a start switch 19 that is operated when starting or stopping the hybrid system 4. In the hybrid vehicle 1, when the start switch 19 is turned on with the brake pedal depressed when the shift lever is in the parking position, the hybrid system 4 is activated. The power supply ECU 17 is connected to an ACC relay 20 for switching on / off of the accessory power source, and an IG1 relay 21 and an IG2 relay 22 for switching on / off of the ignition system.

  A hybrid ECU 23 that performs overall control of the hybrid system 4 is connected to the verification ECU 7 through a bus 12. An engine ECU 24 that performs ignition control and fuel injection control of the engine 2 is connected to the hybrid ECU 23 by CAN (Contoroller Area Network) communication, and a motor 3 is connected via an inverter 25. The hybrid ECU 23 obtains an engine output and a motor torque according to the driving state according to the accelerator opening, the shift position, and output signals from various sensors, and controls the driving force by outputting the required values to the various ECUs.

  The hybrid vehicle 1 is equipped with a battery pack 26 in which the battery system parts are housed in one case and the parts are unitized. As shown in FIG. 2, the battery pack 26 has a case 27 formed by assembling a battery cover 27 a to a lower case 27 b that forms a pair with the battery cover 27 a. Further, as shown in FIG. 3, the battery pack 26 is disposed below the rear seat 28 as a position having a high antitheft effect.

  As shown in FIG. 1, the battery pack 26 is provided with a battery 29 as a storage battery component. The battery 29 includes a battery module 30 formed by connecting a plurality of cells 30 a in series, and a system main relay 32 connected in series to a high voltage power supply circuit 31 of the battery module 30. The motor 3 and the inverter 25 are connected to the inverter 25 and the battery 29 by a power cable 33 that is a high-voltage and large-current electric wire. The system main relay 32 is connected to the hybrid ECU 23 and connects or disconnects the high voltage power supply circuit 31 according to a command from the hybrid ECU 23. The battery 29 corresponds to a storage battery.

The battery pack 26 is provided with a battery ECU 34 that monitors the state of charge of the battery 29. The battery ECU 34 is integrally assembled with the battery module 30 in the case 27 and is connected to the hybrid ECU 23 via CAN communication. The battery ECU 34 is provided with a CPU 35 that performs overall control of the battery ECU 34, a ROM 36 in which various control programs for operating the battery ECU 34 are written, and a RAM 36 a that is used as a work area during operation. It is connected. The ROM 36 stores a control program for monitoring the state of charge of the battery 29. The CPU 35 monitors the state of charge of the battery 29 by operating according to this control program. The battery ECU 34 constitutes a storage battery control system component.

  Further, a current sensor 38 that detects the amount of current flowing through the high voltage power supply circuit 31 is connected in the middle of the wiring of the high voltage power supply circuit 31. The current sensor 38 is connected to the battery ECU 34 and outputs a detection signal corresponding to the value of the current flowing through the high voltage power supply circuit 31 to the battery ECU 34. The CPU 35 monitors the charge of the battery 29 based on the detection signal input from the current sensor 38, and notifies the hybrid ECU 23 of the charge monitoring result when a charge state notification request is received from the hybrid ECU 23. The hybrid ECU 23 grasps the charge state of the battery 29 from the charge monitoring result sent from the battery ECU 34.

  When the battery 29 is charged with the battery external charger, the battery pack 26 is connected with a charging connector 40 to which a charger 39 as a charger can be connected. The charging connector 40 is connected in series to the battery 29, the current sensor 38, and the switch SW. The charger 39 can be connected to the charging connector 40 via the adapter 41, and the power of the AC power source (home commercial power source: AC 100 V) 42 is supplied to the battery 29 via the adapter 41 and the charging connector 40. Can be charged.

  The battery ECU 34 is provided with an EEPROM 43 that can overwrite various data and a counter 44 that counts elapsed time, for example. Among these, in the EEPROM 43, a battery ID code (first identification code) that is a number unique to the battery 29 (battery pack 26) is written. The CPU 35 and the charge control program constitute state value management means, determination means, restriction means, and update means, the EEPROM 43 corresponds to storage means, and the counter 44 constitutes state value management means.

A switch SW for switching on / off of energization of the high voltage power supply circuit 31 is connected to the high voltage power supply circuit 31 in series. The switch SW is connected to the battery ECU 34, and the on / off state is switched based on a command from the battery ECU 34. The switch SW is in an on state in a normal state, and when the battery ECU 34 is in a charge restriction state, the switch SW is turned off and the high voltage power supply circuit 31 is set to an open circuit. Note that the switch SW constitutes a limiting means , a storage battery control system component, and the like.

  The ROM 36 includes a charge restriction program that restricts the charging of the battery 29. The CPU 35 performs an expiration date determination process as a charge restriction process by executing the charge control program. In this example, the expiration date determination process measures the usage period (state value) of the battery ID code with the counter 44, and if the usage period of the battery ID code has passed the expiration date (usage permission range) at the start of charging, The battery 29 is prohibited from being charged by switching off the switch SW in the on state so that no current flows through the high voltage power supply circuit 31. This expiration date is set, for example, as an expiration date such as one month from the update date.

  The verification ECU 7 can wirelessly communicate with the dedicated key 45 that can update the expiration date of the battery ID code in the EEPROM 43. Even if the dedicated key 45 does not have the portable device 5 at hand, the hybrid system 4 can be activated only by this, and the battery number verification is performed as a verification of the battery ID code between itself and the hybrid vehicle 1. Is a key that allows the expiration date of the battery ID code registered in the battery ECU 34 to be updated on condition that the hybrid system 4 is activated in this state. The dedicated key 45 corresponds to the first key.

  The dedicated key 45 is provided with a communication mechanism 46 that wirelessly communicates with the verification ECU 7 in the same communication form as the portable device 5 and an EEPROM 47 that can overwrite data. In the EEPROM 47, a battery ID code is registered as a code string unique to the dedicated key. When the communication mechanism 46 of the dedicated key 45 receives the LF signal from the in-vehicle LF transmitter 9 and recognizes that the signal is the request signal Sreq, the battery ID code registered in the EEPROM 47 is used as the battery ID signal Sel for the RF band. Reply as.

  When the verification ECU 7 receives the battery ID signal Sel via the RF receiver 10, the verification ECU 7 acquires the battery ID code from the battery ECU 34, and stores the battery ID code unique to the dedicated key included in the battery ID signal Sel into the vehicle-side code string. To match. When these battery ID codes match and recognize that the battery number verification is established, the verification ECU 7 enters the same state as when the in-vehicle verification is established, and permits the hybrid system 4 to be activated. At this time, the battery ECU 34 receives a notification of battery number verification establishment from the verification ECU 7. In this case, the battery ID code expiration date of the EEPROM 43 can be updated.

Next, operation | movement of the storage battery apparatus of the electric vehicle of this example is demonstrated.
When charging the battery 29 with an external charging device, the charger 39 is connected to the charging connector 40 via the adapter 41 as shown in FIG. When the charging start operation is performed on the charger 39 in this connected state, the charger 39 that has detected the charging start operation attempts to pass a current to the high voltage power supply circuit 31 via the adapter 41 and the charging connector 40. Here, the CPU 35 always determines whether or not the usage period of the battery ID code counted by the counter 44 is within a preset expiration date. If the usage period of the battery ID code counted by the counter 44 is within the preset expiration date, the CPU 35 permits charging of the battery 29 and keeps the switch SW on.

  For this reason, when current flows from the charger 39 to the high voltage power supply circuit 31, the current from the AC power supply 42 flows into the battery module 30 via the adapter 41 and the charging connector 40 as usual, and the battery 29 is charged. Is done. That is, when charging the battery 29 using the charger 39, if the count value of the counter 44 does not exceed the threshold value previously set in the CPU 35, the charger 29 charges the battery 29. Is possible.

  On the other hand, consider the case where the battery pack 26 (battery 29) is stolen, for example. At this time, since it is unlikely that the dedicated key 45 will be stolen together with the theft of the theft, the expiration date of the battery ID code registered in the EEPROM 43 is not updated, and the expiration date will expire after a while. It will be over the state.

  At this time, the CPU 35 prohibits charging of the battery 29 by switching the normally-on switch SW to OFF at this point and setting the high voltage power supply circuit 31 as an open circuit. Thus, for example, even if a battery theft person connects the charger 39 to the charging connector 40 and starts the charging operation, the current from the charger 39 is not increased because the switch SW is turned off. The battery 29 is not charged.

  Therefore, in this example, even if the battery pack 26 is stolen from the vehicle, charging becomes impossible when the usage period of the battery ID code exceeds the expiration date. This is highly effective in preventing the battery 29 from being stolen. Also, since the expiration date of the battery ID code is updated with the dedicated key 45 that is not usually carried around, it is necessary to steal the dedicated key 45 in order to charge the stolen battery pack 26. This also means that the battery 29 is stolen. Contributes to prevention suppression. Further, whether or not the battery 29 can be charged is determined by a simple process in which the CPU 35 looks at the counter value of the counter 44. Therefore, it is possible to determine whether or not the battery 29 can be charged without using a complicated process.

  Next, a case where the battery ID code registered in the battery ECU 34 is updated will be described. First, consider a case where the driver carries only the portable device 5 when driving the hybrid vehicle 1. At this time, when the portable device 5 possessed by the driver receives the request signal Sreq transmitted by the in-vehicle LF transmitter 9, the portable device 5 returns a vehicle ID signal Sid to the hybrid vehicle 1. When the verification ECU 7 receives the vehicle ID signal Sid via the RF receiver 10, the verification ECU 7 performs in-vehicle verification, and recognizes that the in-vehicle verification is established when the in-vehicle verification is established.

  Subsequently, it is assumed that the driver who gets into the vehicle turns on the start switch 19 while pushing the brake pedal with the shift lever in the parking position in order to start the hybrid system 4 (that is, start the engine). . At this time, the power supply ECU 17 confirms the ID verification result with respect to the verification ECU 7. Upon receipt of this ID verification check request, the verification ECU 7 responds to the power supply ECU 17 with an in-vehicle verification establishment notification if in-vehicle verification (which may include immobilizer verification) is established. When the power supply ECU 17 receives an in-vehicle collation establishment notification from the collation ECU 7, all of the three relays 20 to 22 are turned on.

  The power supply ECU 17 that has turned on the relays 20 to 22 outputs an activation signal to the hybrid ECU 23. The hybrid ECU 23 that has received this activation signal uses encrypted communication with the verification ECU 7 to confirm that the in-vehicle verification is established and whether the ECUs are paired with each other (pairing). . When the hybrid ECU 23 recognizes that both in-vehicle verification and pairing are established, the hybrid ECU 23 enters an operation of turning on the system main relay 32.

  Here, the CPU 35 sequentially monitors whether or not the battery ID code registered in the battery ECU 34 is within the expiration date. If the usage period of the battery ID code is within the expiration date, the switch SW is turned on. Leave it. As a result, when the system main relay 32 is switched on by the hybrid ECU 23, a current flows through the high voltage power supply circuit 31, so that the starter motor rotates and the hybrid system 4 is activated.

  On the other hand, when the battery ID code registered in the battery ECU 34 exceeds the expiration date, the CPU 35 normally switches the switch SW that is on to off at that time. For this reason, when the hybrid ECU 23 turns on the system main relay 32, if the switch SW is off, no current flows through the high voltage power supply circuit 31, and the starter motor does not rotate. Therefore, when the battery ID code exceeds the expiration date, the hybrid system 4 cannot be activated even if the portable device 5 is owned.

  Subsequently, when the hybrid vehicle 1 is operated, when it is desired to update the expiration date of the battery ID code in the battery ECU 34, the dedicated key 45 of this example can perform both the battery ID code update and the hybrid system activation. Therefore, the driver gets on the hybrid vehicle 1 with the dedicated key 45. At this time, since the dedicated key 45 is in a state of receiving the request signal Sreq, the battery ID signal Sel including its own battery ID code is returned to the hybrid vehicle 1 in response to the request signal Sreq.

  When the ID signal included in the RF signal is not the vehicle ID code of the portable device 5 when the RF receiver 10 receives the RF signal, the verification ECU 7 sends the battery ID to the battery ECU 34 via the communication path via the hybrid ECU 23. Request code verification. The CPU 35 that has received the battery ID code confirmation request returns the code string information of the battery ID code registered in its own EEPROM 43 to the verification ECU 7 via the hybrid ECU 23. Note that this processing is not necessarily performed via the hybrid ECU 23, and may be performed directly with the battery ECU 34.

  Upon receiving the battery ID code reply, the verification ECU 7 performs the battery number verification by comparing the battery ID code included in the battery ID signal Sel received by the RF receiver 10 with the battery ID code fetched from the battery ECU 34. . When this battery number verification is established, the verification ECU 7 recognizes that the battery number verification is established.

  Subsequently, it is assumed that the driver who gets into the vehicle turns on the start switch 19 while pushing the brake pedal with the shift lever in the parking position in order to start the hybrid system 4 (that is, start the engine). . At this time, the power supply ECU 17 confirms the ID verification result with respect to the verification ECU 7. The verification ECU 7 that has received this ID verification confirmation request responds to the power supply ECU 17 with a verification establishment notification if at least one of in-vehicle verification and battery number verification is established. When power supply ECU 17 receives the verification establishment notification from verification ECU 7, power supply ECU 17 turns on all three relays 20-22.

  The power supply ECU 17 that has turned on the relays 20 to 22 outputs an activation signal to the hybrid ECU 23. The hybrid ECU 23 that has received this activation signal uses encrypted communication with the verification ECU 7 to confirm that ID verification (in-vehicle verification or battery number verification) is established, and whether the ECUs are paired with each other. Confirmation (pairing). When the hybrid ECU 23 recognizes that both ID verification and pairing are established, the hybrid ECU 23 enters an operation of turning on the system main relay 32.

  When the system main relay 32 is switched to the on state by the hybrid ECU 23, if the battery ID code registered in the battery ECU 34 is within the expiration date, the switch SW remains on, so that the current from the battery 29 is The hybrid system 4 is started by flowing to the starter motor. On the other hand, when the system main relay 32 is switched on by the hybrid ECU 23, if the battery ID code registered in the battery ECU 34 exceeds the expiration date, the switch SW is switched off, so that the starter motor No current flows and the hybrid system 4 does not start.

  The hybrid ECU 23 outputs a system activation notification to the battery ECU 34 when the hybrid system 4 is activated. Upon receiving this system activation notification, the CPU 35 checks with the verification ECU 7 via the hybrid ECU 23 whether the ID verification is in-vehicle verification or battery number verification. At this time, if the in-vehicle collation is established, the collation ECU 7 returns a notification that the in-vehicle collation is established to the battery ECU 34. A completed notification is returned to the battery ECU 34.

  When the CPU 35 receives a notification that the battery number verification has been established from the verification ECU 7, the CPU 35 resets the expiration date of the battery ID code by resetting the counter 44 and restarting the measurement of the usage period from “0”. That is, each time the hybrid system 4 is activated with the dedicated key 45, the expiration date of the battery ID code registered in the battery ECU 34 is updated each time. On the other hand, when receiving a notification that the in-vehicle collation has been established from the collation ECU 7, the CPU 35 does not reset the counter 44 and does not update the battery ID code. That is, even if the hybrid system 4 is activated by the portable device 5, the battery ID code is not updated accordingly.

  As another battery ID code update method, there is a method using a dedicated tool 48 shown in FIG. The dedicated tool 48 is provided with a connection slot 48a into which the dedicated key 45 can be inserted, and a connection cord 48b serving as a communication line when various signals are exchanged between the dedicated tool 48 and an external device. The dedicated tool 48 is provided with a wireless mechanism 49 capable of performing wireless communication with the dedicated key 45 set in the connection slot 48a.

  A service connector 50 capable of connecting the connection cord 48b of the dedicated tool 48 is provided on the inner wall surface 1a of the hybrid vehicle 1. The service connector 50 can also be used as a connector for connecting a diagnostic tool, for example. Further, the service connector 50 is connected to a gateway ECU 51 which functions as an interface between the ECUs as shown in FIG. For example, CAN communication is adopted for communication between the hybrid ECU 23 and the gateway ECU 51. The dedicated tool 48 corresponds to a communication device, and the service connector 50 corresponds to a connector portion.

  The wireless mechanism 49 starts when it detects that the dedicated key 45 is inserted into the connection slot 48a, and performs wireless communication similar to that of the portable device 5 with the dedicated key 45. To obtain the battery ID signal Sel. The wireless mechanism 49 that has acquired the battery ID signal Sel sends the code string information of the battery ID code included in the battery ID signal Sel to the gateway ECU 51 via the connection code 48b and the service connector 50.

  When the gateway ECU 51 acquires the code string information of the battery ID code from the dedicated tool 48 via the service connector 50, the gateway ECU 51 transfers the code string information to the verification ECU 7 via the hybrid ECU 23 using CAN communication. When the verification ECU 7 inputs the battery ID code from the dedicated tool 48, if the code string is not the vehicle ID code of the portable device 5, the verification ECU 7 requests the battery ECU 34 to confirm the battery ID code through a communication path via the hybrid ECU 23. The CPU 35 that has received the battery ID code confirmation request returns the code string information of the battery ID code registered in its own EEPROM 43 to the verification ECU 7 via the hybrid ECU 23.

  The collation ECU 7 that has received the battery ID code response from the battery ECU 34 collates the battery ID code acquired from the dedicated tool 48 with the battery ID code fetched from the battery ECU 34, thereby collating the battery number. When this battery number verification is established, the verification ECU 7 recognizes that the battery number verification is established. Therefore, even if the hybrid system 4 is activated by the portable device 5 instead of the dedicated key 45, if the battery number verification is established by the dedicated tool 48, the expiration date of the battery ID code of the battery ECU 34 is updated each time.

  Therefore, even if the battery ID code has an expiration date, if the dedicated key 45 or the dedicated tool 48 can be used to update the battery ID code, the battery ID code is periodically updated to It is possible to start up normally. In addition, since this kind of dedicated key 45 is not a key that is usually carried around, if such a key is provided with an expiration date update function, the expiration date of the battery ID code is updated by a third party without permission. This situation is unlikely to occur.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) Even if the battery pack 26 is stolen from the vehicle body of the hybrid vehicle 1, it cannot be charged after the expiration date of charging has expired. Therefore, even if the battery pack 26 is stolen, the battery pack 26 cannot be used as usual after a certain period of time. Therefore, the thief's willingness to steal the battery pack 26 is killed. Therefore, in the hybrid vehicle 1, the battery pack 26 is unlikely to be theft object, and the anti-theft effect of the battery pack 26 can be enhanced. Further, since the determination of whether or not the battery 29 can be charged is performed by a simple process in which the CPU 35 looks at the counter value of the counter 44, it is possible to determine whether or not the battery 29 can be charged without using a complicated process.

  (2) When the usage period of the battery pack 26 exceeds the expiration date, the battery 29 cannot be charged at all. Therefore, the battery pack 26 does not function as a storage battery component after a certain period. Therefore, after the usage period of the battery pack 26 exceeds the expiration date, it does not make sense to own the battery pack 26, so this is very effective in reducing the willingness to steal the battery pack 26.

  (3) Even if an expiration date is given to the use of the battery pack 26, the expiration date can be updated on the condition that the exclusive key 45 is owned and the ID verification is established between the dedicated key 45 and the hybrid vehicle 1. To do. Therefore, even if an expiration date is given to the use of the battery pack 26, if the vehicle owner is the vehicle pack 26, the expiration date of the battery pack 26 is updated by using the dedicated key 45 so that the battery pack 26 is continuously used. be able to.

  (4) To operate the stolen battery pack 26 as usual, it is necessary to simultaneously steal the dedicated key 45 that is not normally carried around. Therefore, since it is difficult to steal both the battery pack 26 and the dedicated key 45, this is also highly effective in suppressing the theft of the battery pack 26.

  (5) When collating the battery ID code of the dedicated key 45 with the code string on the vehicle side, the collation ECU 7 performs this ID collation. Accordingly, since the ID verification between the hybrid vehicle 1 and the portable device 5 and the ID verification between the hybrid vehicle 1 and the dedicated key 45 are performed by the same verification ECU 7, the verification ECU 7 and related parts are connected to the portable device. 5 and the dedicated key 45 can be shared. For example, effects such as a reduction in the number of parts and a reduction in the apparatus size can be obtained as compared with the case where these are performed by separate verification system parts.

  (6) The expiration date of the battery ID code of the battery ECU 34 is updated on the assumption that the battery ID code of the dedicated key 45 matches the battery ID code registered on the vehicle side and the battery number verification is established. It is updated on condition that 4 is activated. By the way, if only the battery number verification is established as a condition for updating the expiration date of the battery ID code, the expiration date of the battery ID code may be updated when the vehicle owner is unconscious. If the expiration date update is based on two conditions of battery number verification establishment and hybrid system activation, it is possible to make it difficult to generate a situation in which the expiration date of the battery ID code is updated unconsciously.

  (7) The battery ECU 34 that manages the charging restriction is incorporated in a large component called the battery module 30. By the way, when the battery ECU 34 is provided with a charge restriction function as in this example, it is also conceivable to eliminate the charge restriction of the battery 29 by replacing the battery ECU 34. However, if the battery ECU 34 is incorporated in the battery module 30, the battery ECU 34 is built in the large component, and therefore the battery ECU 34 cannot be easily replaced, which is also effective in suppressing the theft of the battery pack 26. Is expensive.

  (8) The expiration date of the battery ID code of the battery ECU 34 can be updated by using a dedicated tool 48 in a dealer or the like. Therefore, it is possible to update the expiration date of the battery ID code not only by the ID verification according to the radio by the dedicated key 45 but also by the wire using the dedicated tool 48. Therefore, when the expiration date of the battery ID code is updated. The number of options for the update method increases, and even if an expiration date update is provided, the usability is improved.

(9) The battery 29 is also used as a drive source for the starter motor when the hybrid system is activated. In this example, since the battery 29 cannot be charged unless the expiration date of the battery ID code is renewed, even if the thief steals the hybrid vehicle 1, the vehicle itself cannot be moved unless the dedicated key 45 is stolen at the same time. Therefore, it is also effective in suppressing vehicle theft.
(10) The dedicated key 45 can perform both the battery ID code update and the hybrid system start-up operations. Therefore, if one key is possessed, these functions can be performed, which is convenient from the viewpoint of carrying a key. Improves.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. Note that the second embodiment has a configuration in which the charge restriction determination criteria described in the first embodiment are only changed. Therefore, the same parts are denoted by the same reference numerals, detailed description thereof is omitted, and only different parts will be described.

  As shown in FIG. 6, the battery ECU 34 is provided with a GPS (Global Positioning System) module 52 that identifies the current position of the hybrid vehicle 1. The GPS module 52 is a device that calculates the latitude, longitude, altitude and the like with high accuracy using radio waves transmitted from a plurality of artificial satellites, and is connected to the CPU 35. The GPS module 52 can output current position information of the hybrid vehicle 1 calculated from a plurality of radio waves transmitted from artificial satellites to the CPU 35. Note that the GPS module 52 corresponds to detection means.

  The CPU 35 performs chargeable area determination processing for determining whether or not charging is possible by determining whether or not the current position (state value) of the hybrid vehicle 1 is within a designated area (usage permission range), for example, within a prefecture or in Japan. Do. The designated area is set by, for example, registering it in the ROM 36 of the battery ECU 34 in advance, or by connecting an external input device to the battery ECU 34 and inputting the designated area data into the EEPROM 43. You may make it perform work. When the battery 29 is charged by the hybrid ECU 23, the CPU 35 limits the charging of the battery 29 if the current position of the hybrid vehicle 1 obtained by the GPS module 52 is outside the designated area.

  Here, the CPU 35 always determines whether or not the current position of the hybrid vehicle 1 determined by the GPS module 52 is within the designated area. If the current position of the hybrid vehicle 1 determined by the GPS module 52 is within the designated area, the CPU 35 permits charging of the battery 29 and keeps the switch SW on. Therefore, when the charger 39 is operated to start charging, the battery 29 is charged as usual. Therefore, if the position of the hybrid vehicle 1 is within the designated area, the battery 29 can be charged using the charger 39.

  On the other hand, for example, when the battery pack 26 (battery 29) is stolen and removed from the vehicle, it may be resold and taken out of the prefecture or outside the country. Since the CPU 35 always determines whether the battery pack 26 is inside or outside the designated area based on the current position information from the GPS module 52, when the battery pack 26 is taken out of the prefecture or outside the country, the hybrid Recognizing that the current position of the vehicle 1 is outside the designated area (outside the prefecture or outside the country), the switch SW is turned off at this time, and charging of the battery 29 is prohibited.

  Therefore, when the switch SW is in the off state, even if the battery thief connects the charger 39 to the charging connector 40 and starts the charging operation, the switch SW is in the off state. The current does not flow through the high voltage power supply circuit 31, and the battery 29 is not charged. For this reason, even if the battery pack 26 is stolen from the vehicle, if the current position of the battery pack 26 is outside the designated area, the battery 29 cannot be charged. The effect of preventing theft of the battery 29 is high.

Therefore, according to the second embodiment, the following effect can be obtained in addition to the effect (7) described in the first embodiment.
(11) Even if the battery pack 26 is stolen from the vehicle body of the hybrid vehicle 1, the battery pack 26 cannot be charged if the current position of the battery pack 26 is outside the designated area. Therefore, even if the battery pack 26 is stolen, if the battery pack 26 is out of the designated area, it cannot be used as usual, so that the thief's willingness to steal the battery pack 26 is killed. Therefore, in the hybrid vehicle 1, the battery pack 26 is unlikely to be theft object, and the anti-theft effect of the battery pack 26 can be enhanced.

  (12) If charging of the battery 29 is prohibited when the current position of the battery pack 26 is outside the designated area, if the stolen battery pack 26 is taken out of the designated area, the battery is immediately charged at that time. 29 can be prohibited from being charged. Therefore, a theft person who wants to take the stolen battery pack 26 out of the prefecture or outside the country will be killed, and the battery pack 26 is highly effective in suppressing theft in such a case.

In addition, the said embodiment is not limited to the structure so far, You may change into the following aspects.
In the first embodiment, the method of determining whether or not the usage period of the battery ID code has exceeded the expiration date is a method of counting the usage period with the counter 44 and determining whether or not this count value has exceeded a threshold value. It is not limited. For example, the battery ECU 34 has a built-in clock, and a charge permission date (year, month, day) is written in the EEPROM as an expiration date. If the current time exceeds the charge permission date, the battery pack 26 is charged. The method of prohibiting may be used.

  -In 1st Embodiment, it is not limited to enabling the use expiration date of the battery pack 26 to be renewable by registering battery ID code in battery ECU34. That is, when the use of the battery pack 26 exceeds the expiration date, the battery pack 26 is in a charge prohibited state, but the structure may not be returned to the chargeable state.

  In the first embodiment, the expiration date update of the battery ID code is not limited to being updated when the hybrid system 4 is activated on the assumption that the battery number verification by the dedicated key 45 is established. For example, the battery ID code in the battery ECU 34 is updated before the hybrid ECU 23 enters the on operation of the system main relay 32 only on the condition that the battery number verification is established between the dedicated key 45 and the hybrid vehicle 1. You may make it do. As another example, when the start switch 19 is turned on, the collation ECU 7 confirms ID collation establishment, and if the battery number collation is established, the hybrid ECU 23 turns on the system main relay 32. The battery ID code may be updated before entering. In these cases, even if the usage period of the battery ID code exceeds the expiration date, if the dedicated key 45 is owned, the expiration date of the battery ID code is entered before the start of the start-up operation of the hybrid system 4. Therefore, even if the battery ID code exceeds the expiration date, the hybrid system 4 can be activated as usual.

  In the first embodiment, the dedicated key 45 is not limited to a key capable of performing both operations of battery ID code update and hybrid system activation, and may be a key dedicated to battery ID code update, for example. In this case, in order to update the battery ID code while starting the hybrid system 4, it is necessary to possess both the portable device 5 and the dedicated key 45. Further, this type of expiration date update function may be incorporated in the portable device 5.

  In the first embodiment, the battery number verification of the battery ID code transmitted from the dedicated key 45 is not limited to being performed by the verification ECU 7 that performs ID verification with the portable device 5. For example, the battery ECU 34 may be provided with an antenna function or an ID collation function, and the battery ECU 34 may collate the battery number of the battery ID code.

In the first embodiment, the expiration date set in the battery ECU 34 is not necessarily limited to one, and the setting can be freely changed.
-In 1st Embodiment, the update of an expiration date is not necessarily limited to the structure which uses the exclusive key 45. FIG. For example, as shown in FIG. 7, a communication circuit 53 capable of network communication (Internet communication, wireless LAN communication, etc.) is provided in the hybrid vehicle 1, and ID verification is performed with the server 54 via the communication circuit 53. Thus, the expiration date may be updated. According to this configuration, when the hybrid system 4 is activated, the battery ECU 34 transmits the battery ID code to the server 54 via the communication circuit, and the server 54 that has received the battery ID code registers this battery ID code in itself. If it has been registered, an update permission notice is returned to the battery ECU 34 through the communication circuit 53. When the battery ECU 34 receives the update permission notification from the server 54, the battery ECU 34 resets the counter 44 and updates the expiration date of the battery ID code. Therefore, for example, a situation in which the dedicated key 45 that may occur in the case of a structure in which the expiration date is updated with the dedicated key 45 is not stolen occurs, and the effect of preventing unauthorized charging of the battery 29 is extremely high. Note that the CPU 35 constitutes server side update means, and the communication circuit 53 corresponds to communication means.

  In the second embodiment, a GPS system component is required in this case, but this is not limited to the GPS module 52 built in the battery ECU 34. For example, when a car navigation device is mounted on the hybrid vehicle 1, the battery ECU 34 may acquire current position information from a GPS built in the car navigation device, and the battery ECU 34 may determine the current position using this. In this case, if the connection between the battery ECU 34 and the car navigation device is cut, the battery ECU 34 may take a process of shifting to a charge prohibited state, so that charging when the battery pack 26 is removed from the vehicle is prohibited. It is possible to satisfy.

-In 2nd Embodiment, the designation | designated area used as the judgment reference | standard of chargeability is not necessarily limited to only one, A setting change is possible freely.
In the first and second embodiments, the charging limitation is not necessarily limited to charging prohibition, for example, a mode in which the time required for charging is longer than usual, or charging is limited only for a certain period and after a certain period You may make it transfer to the mode which returns to a normal state.

  In the first and second embodiments, one of two processes of an expiration date determination process for giving an expiration date to use of the battery pack 26 and a chargeable area determination process for giving the battery pack 26 an available area However, the present invention is not limited to performing only the above, and both of these processes may be performed by one hybrid vehicle 1.

  -In 1st and 2nd embodiment, when the battery 29 will be in a charge restriction state during driving | running | working of a vehicle, not only turning off switch SW immediately, but the hybrid system 4 will stop, ie, the engine 2 will be in a stop state. In this case, the switch SW may be turned off.

  In the first and second embodiments, the switch system component for switching the high voltage power supply circuit 31 to the open circuit when charging the battery 29 is not limited to the switch SW provided in the high voltage power supply circuit 31, for example, the system The main relay 32 may have this function. The switch for connecting or disconnecting the high voltage power supply circuit 31 is not limited to the mechanical contact switch SW, and the type of switch is not particularly limited as long as the high voltage power supply circuit 31 can be connected or disconnected.

In the first and second embodiments, the electric vehicle is not limited to the hybrid vehicle 1 and may be an electric vehicle that moves only by a motor, for example.
