So far, the battery replacement of the electric vehicle is completed, and the battery replacement device 12A moves away from the preset battery replacement position.

Example 7

The battery replacement control system of this embodiment is a further improvement on the basis of Embodiment 1, which is mainly reflected in the battery replacement control process of the battery replacement control system. The battery swap control process in this embodiment is divided into a battery swap preparation process before the electric vehicle is parked on the vehicle-carrying platform and a battery swap operation process after the electric vehicle is parked on the vehicle-carrying platform. During the battery swap preparation process and the battery swap operation process, the control instructions of the control unit are different from those in Embodiment 6.

During the battery replacement preparation process, the control unit 11 can pre-select the second battery storage rack 13B, configure the battery removal and replacement device 12B, and control the battery removal and replacement device 12B to complete part of the instructions, so as to Save time when unloading the battery. Wherein, the process of selecting the second battery placement rack 13B may refer to Embodiment 2-4, and the process of configuring the battery removal and battery replacement device 12B may refer to Embodiment 5.

Wherein, the control unit 11 controls the battery removal and battery replacement device 12B to complete a part of the instructions, including: the control unit 11 judges whether the preset battery replacement position is in a parking state, so as to set the second preset waiting position, sending a second movement instruction to the battery removal and replacement device 12B, the second movement instruction is used to order the battery removal and replacement device 12B to park at the second preset waiting position in advance. The battery removal and battery replacement device 12B is also used to execute the second movement instruction. Wherein, the second preset waiting position is related to the preset battery swap position, and may be the same position as the preset battery swap position or a position near the preset battery swap position (for the preset Refer to Embodiment 6) for the description of setting the replacement position.

The judging whether the preset power exchange position is in a parkable state may specifically include:

When the following conditions are met at the same time, the preset power exchange position is in a parking state, otherwise, the preset power exchange position is in an unparkable state:

Condition (1): The preset battery replacement position is vacant;

Condition (2): there is a path for the battery removal and battery replacement device 12B to move to the preset battery replacement position;

Condition (3): It is predicted that when the battery removal and battery replacement device 12B is parked at the preset battery replacement position, the battery removal and battery replacement device 12B will not block the electric vehicle driving into the vehicle loading platform.

Whether the condition (3) can be met is usually related to the structure of the vehicle-carrying platform.

Taking the vehicle-carrying platform of the first structure in Embodiment 6 as an example, since the electric vehicle is parked on the vehicle-carrying platform when changing batteries, and the preset battery-changing position is usually located below the vehicle-carrying platform, so , usually, even if the battery unloading and battery replacement equipment 12B is parked at the preset battery replacement position before the electric vehicle drives into the vehicle loading platform, the battery unloading and battery replacement equipment 12B will not The electric vehicles on the vehicle-carrying platform cause obstruction, and the condition (3) can be satisfied.

Taking the vehicle-carrying platform of the second structure in Embodiment 6 as an example, since the electric vehicle is parked on the lifting platform when changing batteries, and the preset battery-changing position is usually located above the vehicle-carrying platform, Therefore, if the battery unloading and battery replacement equipment 12B is parked at the preset battery replacement position before the electric vehicle drives into the vehicle loading platform, then, when the electric vehicle drives into the vehicle loading platform, the unloading battery The battery replacement equipment 12B is likely to block the incoming electric vehicles. Therefore, for the vehicle-carrying platform of the second structure, the preset battery replacement position usually cannot meet the condition (3), and thus it is in an unparkable state.

When the preset battery swapping position is in a parking state, the second preset waiting position is the same as the preset battery swapping position. When the preset battery replacement position is in a non-parking state, the second preset waiting position is a position that is no more than a second distance threshold from the preset battery replacement position, that is, a location near the preset battery replacement position Location.

In this embodiment, if the battery model applicable to the electric vehicle is predictable before the electric vehicle is parked on the vehicle-carrying platform, then, during the preparation process for battery replacement, the control unit 11 may also pre-select Take out the first battery rack 13A, configure the battery-installation and replacement equipment 12A, and control the battery-installation and replacement equipment 12A to complete part of the instructions, so as to save battery installation time. Wherein, the process of selecting the second battery placement rack 13B may refer to Embodiment 2-4, and the process of configuring the battery removal and battery replacement device 12B may refer to Embodiment 5. In addition, the battery model applicable to the electric vehicle can be predicted in the following manner: the vehicle-carrying platform is only limited to berthing electric vehicles applicable to the battery of the model. For example, if a vehicle-carrying platform is preset to be limited to parking electric vehicles with a specific type of battery, then, no matter whether the electric vehicle has been parked on the vehicle-carrying platform, it can be determined that the battery model applicable to the electric vehicle must be the specified battery type. model.

Wherein, the control unit 11 controls the battery replacement device 12A to complete a part of instructions, including: the control unit 11 sends a battery fetch command to the battery replacement device 12A, and the battery fetch command is used to instruct the The battery replacement device 12A removes the battery to be installed from the first battery placement rack 13A. The battery replacement device 12A is also used to execute the battery fetching instruction.

The control unit 11 is further configured to send a first movement instruction to the battery installation and replacement equipment 12A after the battery installation and replacement equipment 12A executes the battery fetching instruction, and the first movement instruction is used to command The battery-installed and battery-replacing equipment 12A is pre-parked at a first preset waiting position, and the first preset waiting position is near the vehicle-carrying platform, which is a position not exceeding a first distance threshold from the vehicle-carrying platform . The battery replacement device 12A is also used to execute the first moving instruction.

So far, the battery swap preparation process is completed, and the battery swap control system waits for the electric vehicle to drive into and park on the vehicle-carrying platform to enter the battery swap operation process.

During the battery replacement operation, the control unit 11 judges whether the second preset waiting position where the battery replacement device 12B is located is the same position as the preset battery replacement position:

If yes, send a battery unloading command to the battery unloading and battery replacement device 12B, the battery unloading command is used to order the battery unloading and battery replacement device 12B to remove the battery that lacks power from the electric vehicle; The electric device 12B is also used to execute the battery unloading command;

If not, send a fine-tuning instruction to the battery removal and battery replacement device 12B, the fine-tuning instruction is used to instruct the battery removal and battery replacement device 12B to move from the second preset waiting position to the preset battery replacement position ; The battery unloading and battery replacement equipment 12B is used to execute the fine-tuning instruction; then, the control unit 11 sends the battery unloading instruction to the battery unloading and battery replacement equipment 12B; the battery unloading and battery replacement equipment 12B also uses to execute the command for unloading the battery.

The control unit 11 is further configured to send a fourth moving instruction to the battery removing and replacing device 12B after the battery removing and replacing device 12B executes the battery removing instruction, and the fourth moving instruction is used to command The battery removal and battery replacement equipment 12B moves to the second battery storage rack 13B and places the depleted battery in the empty battery storage compartment. The battery removal and battery replacement device 12B is also used to execute the fourth movement instruction.

The control unit 11 is further configured to send a message to the battery replacement device 12B after the battery replacement device 12B leaves the preset power replacement position or leaves the preset power replacement position beyond a third distance threshold. A fifth movement instruction, the fifth movement instruction is used to instruct the battery replacement device 12A to move to the preset power replacement position. The battery replacement device 12A is also used to execute the fifth movement instruction.

The battery-installation-replacement device 12A is also used to execute the battery-installation instruction. So far, the battery replacement of the electric vehicle is completed, and the control unit 11 commands the battery-installed power replacement device 12A to move away from the preset power replacement position.

The battery replacement control system of this embodiment completes part of the control during the battery replacement preparation process, which greatly shortens the battery replacement time after the electric vehicle enters the vehicle loading platform, and improves the power replacement efficiency.

Example 8

Fig. 5 shows a battery replacement control method in this embodiment. The battery replacement control method includes:

Step 21, selecting a battery storage rack meeting the first condition from at least one battery storage rack as the first battery storage rack. Wherein, the battery storage rack has several battery storage compartments for placing batteries, and the first condition is set to place batteries suitable for electric vehicles, and the batteries suitable for electric vehicles usually refer to batteries that are compatible with the electric vehicles. The batteries used are the same type.

Step 22, selecting a battery storage rack meeting the second condition from the at least one battery storage rack as a second battery storage rack. Wherein, the second condition is set to have an empty battery storage compartment.

Step 23, configuring at least one of the at least two power-swapping devices as a battery-installed power-swapping device. Wherein, the battery replacement equipment is used to transport the battery to be installed, and the battery to be installed is a battery that is removed from the first battery storage rack and is suitable for the electric vehicle and will be installed in the electric vehicle. .

Step 24, configuring at least one of the at least two power-swapping devices as a battery-swapping device. Wherein, the battery removal and replacement equipment is used for transporting a battery that is short of power, and the battery short of power is a battery that is removed from the electric vehicle and will be placed in the empty battery storage compartment.

The order of the above steps is only a possible order of the above steps. In other embodiments, the above steps can be in other orders, such as performing step 22 first, and then performing step 24, step 21, and step 23 in sequence, or, First execute step 21, and then execute step 23, step 22, and step 24 in sequence.

In this embodiment, in the whole process of changing the battery for the vehicle, two power changing devices are used, namely the battery changing device and the battery changing device. Between the rack and the electric vehicle, the transportation of the battery to be installed is realized. The moving track of the unloading battery replacement equipment is between the electric vehicle and the second battery storage rack, and the transportation of the battery that is short of power is realized. The two power replacement devices have different responsibilities, and jointly complete the task of battery replacement, which shortens the entire battery replacement time by at least half compared to using only one battery replacement device, and improves the speed and efficiency of battery replacement.

Example 9

The battery replacement control method in this embodiment is a further improvement on the basis of Embodiment 8, mainly reflected in the setting of the first condition. The first condition is used as the basis for selecting the first battery placement rack. In addition to the necessary placement of batteries suitable for the electric vehicle, other preferred matching conditions can be further set. In this embodiment, the matching condition is mainly related to the electric quantity of the battery, and the battery replacement control method further includes: monitoring the electric quantity of the battery placed on the battery shelf.

Specifically, the first condition may be set as a fully charged battery suitable for the electric vehicle is placed. Correspondingly, step 21 specifically includes: judging whether there is a battery storage rack meeting the first condition in the at least one battery storage rack, and if so, selecting one of them as the first battery storage rack. If there is no battery storage rack meeting the first condition, an alarm signal may be sent to indicate that the electric vehicle cannot be replaced.

Or, in order to improve the probability of being able to replace the battery for the electric vehicle, the first condition can be preferentially set to place a battery that is suitable for the electric vehicle and is fully charged, if the at least one battery placement rack does not have a As for the battery placement rack of the first condition, the first condition is modified to be placed with a battery with the highest capacity applicable to the electric vehicle. Correspondingly, step 21 specifically includes: the default setting of the first condition is that a fully charged battery suitable for the electric vehicle is placed, and judging whether there is a battery placed in the at least one battery storage rack that meets the default first condition. frame, if so, then select one as the first battery placement frame, if not, then:

Modifying the first condition is set to place a battery suitable for the electric vehicle and having the highest battery capacity, and judging again whether there is a battery storage rack that meets the current first condition in the at least one battery storage rack, and if so, select from it One as the first battery holder. If there is still no battery storage rack meeting the first condition, an alarm signal may be sent to indicate that the electric vehicle cannot be replaced.

In addition, in this embodiment, the battery storage compartment may also have a battery charging circuit for charging the battery, and the battery replacement control method monitors the power of each battery in real time, which is helpful for the selection of the first battery storage rack.

Of course, in other embodiments, the first condition can also be set to other conditions according to requirements.

Example 10

The battery replacement control method in this embodiment is a further improvement on the basis of Embodiment 8 or 9, which is mainly reflected in the selection of the first battery storage rack and the second battery storage rack. When the number of battery storage racks is two or even more, it is likely that two or more battery storage racks meet the first condition or the second condition at the same time. The battery replacement control method may further set selection requirements for the first battery storage rack and the second battery storage rack according to requirements.

In this embodiment, in order to deal with the situation that two or more battery storage racks meet the first condition at the same time, step 21 may specifically include:

Judging whether there is more than one battery rack meeting the first condition, if so:

From the battery storage racks meeting the first condition, randomly select a battery storage rack as the first battery storage rack;

Or, in order to shorten the moving distance and moving time of the battery replacement equipment and speed up the power replacement efficiency, select a battery storage rack closest to the electric vehicle from the battery storage racks that meet the first condition (if the If the battery vehicle is not parked, select a battery storage rack closest to the vehicle-carrying platform for parking the electric vehicle) as the first battery storage rack.

Of course, if there is only one battery storage rack meeting the first condition, it can only be used as the first battery storage rack.

Similarly, in order to deal with the situation that there are two or more battery storage racks meeting the second condition at the same time, step 22 may specifically include:

It is judged that there is more than one battery rack meeting the second condition, if so:

From the battery storage racks meeting the second condition, randomly select a battery storage rack as the second battery storage rack;

Or, in order to shorten the moving distance and moving time of the battery-dismounting and battery-changing equipment, and to speed up the power-changing efficiency, select a battery shelf closest to the electric vehicle from the battery shelf that meets the second condition (if the If the battery vehicle is not parked, select a battery storage rack closest to the vehicle-carrying platform for parking the electric vehicle) as the second battery storage rack.

Of course, if there is only one battery storage rack meeting the second condition, it can only be used as the second battery storage rack.
