Optionally, the network interface 1004 may include a standard wired interface and a wireless interface (eg, a wireless-fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable memory (Non-volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001 .

Those skilled in the art can understand that the structure shown in FIG. 1 does not constitute a limitation on the intelligent power supply equipment for automobiles, and may include more or less components than those shown in the figure, or combine some components, or arrange different components .

As shown in FIG. 1 , the memory 1005 identified as a computer storage medium may include an operating system, a network communication module, a user interface module, and an automotive intelligent power supplement program.

In the automotive intelligent power supply device shown in FIG. 1 , the network interface 1004 is mainly used to connect to the backend server and perform data communication with the background server; the user interface 1003 is mainly used to connect the user equipment; The processor 1001 invokes the vehicle intelligent power supply program stored in the memory 1005, and executes the vehicle intelligent power supply method provided by the embodiment of the present invention.

Based on the above-mentioned hardware structure, an embodiment of the vehicle intelligent power supplement method of the present invention is proposed.

Referring to FIG. 2 , FIG. 2 is a schematic flowchart of the first embodiment of the method for intelligent power supply for automobiles according to the present invention, and the first embodiment of the method for intelligent power supply for automobiles according to the present invention is proposed.

In this embodiment, the vehicle intelligent power supplement method includes the following steps:

Step S10: Obtain the vehicle state of the target vehicle and the low voltage battery voltage signal.

It should be noted that the executive body of this embodiment may be a device with a battery charging function, and the device may be connected to a battery management system (BMS), a vehicle controller (VCU), and a direct current converter (DC/DC) in the vehicle. DC) connected computing devices, such as: on-board computers, notebooks, etc., this embodiment does not limit this. In this embodiment and the following embodiments, the battery charging control device is used as an example to describe the intelligent charging method for automobiles of the present invention. Be explained.

It should be understood that the target vehicle can be a pure electric vehicle: a vehicle driven by an on-board power supply and driven by a motor that meets the requirements of road traffic and safety regulations. The vehicle state refers to the vehicle being powered on at low voltage ( ON gear), low-voltage battery charging status (locking/OFF gear) status. Low-voltage battery refers to the source of energy consumed for starting pure electric vehicles and low-voltage electrical appliances.

It should be understood that the low-voltage battery voltage signal may be a signal collected through a LIN line, and the signal collected through a LIN line is suitable for a system with low bus performance compared to a CAN line. Compared with CAN line communication, LIN line communication only transmits the status signals of several components such as low-voltage batteries. Compared with CAN line communication, which transmits all the controller signals of the whole vehicle, LIN line communication transmits less signals and has strong stability.

Step S20: Generate and send the supplementary power request information to the mobile terminal according to the vehicle state and the low-voltage battery voltage signal.

It should be noted that the power supplement request information refers to the request information used to remind the user to supplement the power when the vehicle needs to be powered up. Electricity duration and other information. The mobile terminal may be an intelligent terminal loaded with power-supplying software, such as a mobile phone, a tablet, and the like.

In the specific implementation, the vehicle controller determines whether the battery needs to be recharged by obtaining the vehicle status and the low-voltage battery voltage signal. Information such as the duration of power supplementation generates power supplement request information, and sends the power supplement request information to the mobile terminal to remind the user.

Further, in order to solve the problem that when the pure electric vehicle is in the OFF gear, when the voltage of the low-voltage battery is too low, the low-voltage battery cannot be reminded and the low-voltage battery cannot be supplemented, so that the low-voltage battery cannot provide enough power for starting the next time. Or when the pure electric vehicle is locked, some controllers will continue to consume the power of the low-voltage battery. When the car is not used for a long time, the voltage of the low-voltage battery will not be able to support operations such as unlocking the vehicle, so the low-voltage battery can only be operated through an external power supply. For the problem of unlocking and starting the vehicle by charging the battery, this embodiment reminds the user in time and authorizes the charging of the battery. The step S20 includes: when the vehicle is in the low-voltage battery charging state, collecting the LIN of the whole vehicle The low-voltage battery voltage signal on the line is used, and whether the battery voltage is in the working voltage range is judged according to the low-voltage battery voltage signal; the power-supply request information is generated according to the voltage judgment result and sent to the mobile terminal.

It should be noted that the low-voltage battery replenishment state means that the vehicle is in the OFF gear state or the vehicle-locked state. The working voltage range refers to the battery voltage range for which the vehicle does not need to be recharged, and the voltage range can be set according to the actual situation.

It is understandable that the voltage judgment result includes two results that the voltage of the low-voltage battery is lower than the working voltage range or not lower than the working voltage range.

It should be understood that when the vehicle is in the OFF gear state or the vehicle is locked, the low-voltage battery voltage signal on the LIN line of the whole vehicle is collected, and when the low-voltage battery voltage signal is lower than the working voltage range, the charging request information is generated and sent to the The mobile terminal reminds the user to authorize the replenishment in time.

Further, the step of generating and sending the supplementary power request information to the mobile terminal according to the voltage judgment result includes: when the voltage of the low-voltage battery is lower than the operating voltage range, generating the supplementary power request information, and sending all the power supplementary request information through the vehicle-mounted terminal. The power supplement request information is sent to the mobile terminal.

It should be noted that the in-vehicle terminal can be a device that interacts with the vehicle CAN bus and can upload data to the cloud.

Step S30: Receive a power supplement authorization signal fed back by the mobile terminal based on the power supplement request information, and control the battery management system to supplement power to the low-voltage battery according to the power supplement authorization signal.

It should be noted that the power supply authorization signal fed back based on the power supply request information refers to the power supply authorization signal input by the user according to the power supply request information after the mobile terminal receives the power supply request information sent by the vehicle terminal. The power replenishment authorization signal includes a confirmation authorization signal and a non-confirmation authorization signal. The confirmation authorization signal indicates that the target vehicle is entered into the intelligent power supply control mode, and the non-confirmation authorization signal indicates that it is determined not to enter the intelligent power supply control mode. The above two situations can be Meet the needs of vehicles in different scenarios.

In this embodiment, the vehicle state of the target vehicle and the low-voltage battery voltage signal are obtained; the power-supply request information is generated according to the vehicle state and the low-voltage battery voltage signal and sent to the mobile terminal, and the power-supply authorization signal fed back by the mobile terminal based on the power supply request information is received, and Control the battery management system to supplement the low-voltage battery according to the power-supply authorization signal. Because this embodiment uses the vehicle status, the low-voltage battery voltage signal, and the mobile terminal to control the battery management system to supplement the low-voltage battery, compared with the prior art, the user cannot be reminded to perform the automatic charging of the low-voltage battery in time, resulting in the user's concern for the pure battery. The electric vehicle experience is poor. In this embodiment, the low-voltage battery of the pure electric vehicle can be automatically recharged with the authorization of the user, so as to ensure sufficient battery power and improve the user's experience of the pure electric vehicle.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of the second embodiment of the method for intelligent vehicle power supply according to the present invention. Based on the first embodiment shown in FIG. 2 above, a second embodiment of the method for intelligent vehicle power supply according to the present invention is proposed.

In this embodiment, the step S30 includes:

Step S301: Receive a power supplement authorization signal fed back by the mobile terminal based on the power supplement request information.

Step S302: Generate a power-on command according to the power-supply authorization signal, and send the power-on command to a battery management system to control the DC converter to power-supply the low-voltage battery.

It should be noted that when receiving the power-supply authorization signal from the user based on the confirmation of authorization fed back by the mobile terminal, the VCU determines to enter the power-supply mode after receiving the power-supply signal, and sends a high-voltage command to the BMS. When commanded, the BMS closes the main positive, main and negative relays, so that the DC/DC is powered off from the battery pack to supplement the low-voltage battery.

In this embodiment, before the step of receiving the power supplement authorization signal fed back by the mobile terminal based on the power supplement request information, the step further includes: acquiring a user feedback time; when the user feedback time exceeds a first time period , send the power supply request information for the second time through the vehicle-mounted terminal; when the user feedback time exceeds the second time period, send the power supply request information for the third time through the vehicle-mounted terminal; When the feedback time exceeds the third time period, the whole vehicle is controlled to enter the sleep mode.

It should be noted that, in order to avoid missing the charging time due to the user forgetting to confirm and authorize the vehicle to enter the charging mode, the user is reminded by setting reminder modes with different time gradients.

It is understandable that the user feedback time refers to the feedback time for the mobile terminal to confirm the authorization after receiving the power supply request information, and the first time period may be the time when the mobile terminal makes feedback when it receives the power supply request information for the first time. Time period, for example: 10 minutes, the second time period may be the time period during which the mobile terminal makes feedback when receiving the second power supply request information, and the third time period may be the time period when the mobile terminal receives the second power supply The time period during which feedback is made when requesting information.

In the specific implementation, in order to further illustrate the overall control process, please refer to Figure 4 for the schematic diagram of the vehicle control process. By collecting the low-voltage battery voltage signal on the LIN line of the vehicle, the vehicle controller determines whether the voltage is within the working voltage range. The voltage range is sent to the user's mobile APP through the on-board terminal to determine whether the user confirms the authorization to enter the charging mode. When the feedback time exceeds the first time period, the on-board terminal sends the charging request information to the mobile APP for the second time to continue the judgment. Whether the user confirms the authorization to enter the power supply mode, if the feedback time exceeds the second time period, the vehicle terminal will send the power supply request information to the mobile APP for the third time, and if the feedback time exceeds the third time period, the vehicle will be controlled to enter the sleep mode. If it receives a signal for power supplementation authorized by the user through the mobile phone APP within the preset time period, the vehicle controller enters the power supplementation mode after receiving the command, and sends a high voltage command to the BMS, and the BMS closes the main positive, main and negative relays. The DCDC takes electricity from the battery pack to supplement the low-voltage battery.

In this embodiment, the vehicle state of the target vehicle and the battery voltage signal are obtained; the power supply request information is generated according to the vehicle state and the battery voltage signal and sent to the mobile terminal, and the power supply authorization signal fed back by the mobile terminal based on the power supply request information is received; The authorization signal generates a power-on command, and sends the power-on command to the battery management system to control the DC converter to supplement the low-voltage battery. Since this embodiment uses the vehicle status, the battery voltage signal and the mobile terminal to control the battery management system to recharge the battery, compared with the prior art, the user cannot be reminded to automatically recharge the low-voltage battery in a timely manner, resulting in the user's concern about the pure electric vehicle. The experience is poor. In this embodiment, the battery of the pure electric vehicle can be automatically recharged with the authorization of the user, so as to ensure sufficient battery power and improve the user's experience of the pure electric vehicle.

Based on the above-mentioned first embodiment shown in FIG. 2 , a third embodiment of the vehicle intelligent power supplement method of the present invention is proposed.

In this embodiment, before the step S10, the steps include: starting the Canape test software, and controlling the target vehicle equipment to consume battery power; when the battery power is lower than a preset value, sending power replenishment request information to the mobile terminal; receiving The mobile terminal controls the battery management system to supplement the low-voltage battery based on the confirmation authorization signal fed back by the power-supply request information through the Canape test software and the confirmation authorization signal, and receives the measurement data of the low-voltage battery voltage fed back by the voltmeter When the measured data satisfies the preset power-supply control conditions, determine that the vehicle has completed the power-supply test, control the target vehicle to enter the intelligent power-supply control logic, and obtain the vehicle state and low-voltage battery voltage signal of the target vehicle.

It should be noted that, by carrying out the verification of relevant strategies for intelligent power supply, the power supply control logic of this scheme is more in line with the actual application requirements. During the test, a computer with CANape software, a set of CANape equipment, a A mobile phone with relevant information bound to the vehicle, as well as a calibrated prototype vehicle that can be used normally and the corresponding vehicle controller software. Through the vehicle controller control software, CANape is connected to the vehicle to collect vehicle-related data.

It should be understood that the preset power-supply control condition refers to a preset condition for judging whether the measurement data reaches an effective condition.

In the specific implementation, before the power supply control is performed on the vehicle, the power supply control logic needs to be verified to ensure the accuracy of the intelligent power supply control strategy. That is, the pure electric vehicle is connected to the test equipment through the vehicle diagnostic port, and the CANape software is opened. Turning on high beams and other power-consuming equipment consumes battery power. When it is detected that the low-voltage battery power is lower than the preset value, it sends a power supplement request message to the mobile terminal, and receives a confirmation authorization signal from the mobile terminal based on the power supplement request information feedback. The CANape software confirms that it has entered the power supply mode, and receives the measurement data of the low-voltage battery voltage fed back by the voltmeter, and judges the validity of the intelligent power supply control logic according to the measurement data. After confirming that the vehicle has completed the power supply test, it controls the target vehicle to enter the intelligent power supply control. logic, and perform the steps of acquiring the vehicle state of the target vehicle and the low voltage battery voltage signal.

Further, before the step of receiving the confirmation authorization signal fed back by the mobile terminal based on the power-supply request information, the step further includes: obtaining user feedback time; and generating reminder information when the user feedback time exceeds a preset time period. , the reminder information is sent to the mobile terminal through the vehicle-mounted terminal until the authorization to replenish the power is confirmed.

It should be noted that the reminder information refers to the information that prompts the user to supplement the power, and the preset time period may be set according to the actual situation.

In a specific implementation, referring to FIG. 5 , the schematic diagram of the power supply test flow, when the user does not confirm the authorization, the user's mobile terminal is reminded a second time until the user confirms the authorization for power supply.

In this embodiment, the vehicle state and the battery voltage signal of the target vehicle are acquired; the power supply request information is generated according to the vehicle state and the battery voltage signal and sent to the mobile terminal; the power supply authorization signal fed back by the mobile terminal based on the power supply request information is received; The electric authorization signal controls the battery management system to replenish the battery. Because this embodiment uses the vehicle status, the battery voltage signal, and the mobile terminal to control the battery management system to supplement the battery, compared with the prior art, the user cannot be reminded to automatically supplement the low-voltage battery in time, which leads to the user's concern about the pure electric vehicle. The experience is poor. In this embodiment, the battery of the pure electric vehicle can be automatically recharged with the authorization of the user, so as to ensure sufficient battery power and improve the user's experience of the pure electric vehicle.
