[0003] The present application relates to the field of battery technology, and in particular to a control method and device for a battery entering a battery swap station, a control method and device for a battery leaving a battery swap station, a computing device, a battery swap station, a computer-readable storage medium, and a computer program product. Background Art

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of the sustainable development of the automotive industry. For electric vehicles, battery technology is a key factor in their development.

[0005] When batteries need to be replaced and charged at a battery swap station, manual operation of the battery entry and exit process is often required, which has low reliability and poses safety risks.

[0006] Summary of the Invention

[0007] The present application aims to solve at least one of the technical problems existing in the background art. To this end, embodiments of the present application provide a control method and control device for a battery entering a battery swap station, a control method and control device for a battery leaving a battery swap station, a computing device, a battery swap station, a computer-readable storage medium, and a computer program product to alleviate, mitigate, or eliminate the problems in the related art.

[0008] An embodiment of the first aspect of the present application provides a control method for a battery entering a battery swap station. The battery includes a battery control unit, and the battery swap station includes a battery compartment. The control method includes: in response to the battery being connected to the battery compartment, switching the battery control unit to an in-station mode, the in-station mode being used to instruct the battery control unit to operate within the battery swap station; in response to receiving battery information from the battery control unit, sending a clear instruction to the battery control unit, the clear instruction including an instruction for instructing to clear a subtotal of the battery's last operation within the battery swap station; and in response to receiving clear completion information from the battery control unit, causing a charging device in the battery compartment to charge the battery, the clear completion information including information indicating that clearing of the subtotal of the status information is complete.

[0009] The technical solution of the embodiments of this application provides a control method for batteries entering a battery swap station. This method allows batteries to be charged normally after entering the station. It also clears previous battery status information after entering the station to avoid misjudging the battery status and facilitates recording and storage of relevant information generated by the battery within the station. This standardizes the battery entry process and improves the reliability and safety of battery entry.

[0010] In some embodiments, the in-station mode is used to indicate that the coding value of the battery control unit is updated to a coding value specific to the battery swap station, and the battery information includes a coding value specific to the battery swap station. Before the battery enters the battery swap station, the battery control unit has a coding value. After the battery enters the station, the coding value of the battery control unit is updated to a coding value specific to the battery swap station, so that the battery swap station can communicate and interact normally with the battery control unit based on the specific coding value, thereby improving the reliability of battery storage.

[0011] In some embodiments, the battery control unit includes a wakeup source interface. Switching the battery control unit to in-station mode includes: having the charging device send a wakeup signal to the wakeup source interface to activate the battery control unit and switch the battery control unit to in-station mode. The charging device sends the wakeup signal to the wakeup source interface, waking the battery control unit. The battery control unit then determines that the battery is in the station based on the wakeup signal, thereby accurately determining the battery status. In other words, a single wakeup signal is used to wake up the electronic control unit and switch its state, thereby simplifying the control process.

[0012] In some embodiments, the battery control unit operates within the battery swap station by determining at least one of a subtotal of charged energy, cumulative charged energy, a subtotal of discharged energy, and cumulative discharged energy. While the battery is within the station, the battery control unit stores the relevant information to facilitate determining whether the battery is in a normal state.

[0013] In some embodiments, the control method further includes: monitoring the status of the battery while the charging device is charging the battery. Monitoring the battery status during charging can promptly identify abnormal conditions and improve the safety of the charging process.

[0014] A second aspect of the present application provides a control method for a battery to leave a battery swap station. The battery includes a battery control unit, and the battery swap station includes a battery compartment. The control method includes: in response to receiving a request from the battery to leave the battery swap station, determining whether the connection between the battery and the battery compartment is disconnected; in response to determining that the connection between the battery and the battery compartment is disconnected, sending a clear instruction to the battery control unit, the clear instruction including an instruction for instructing to clear a subtotal of the battery's last operation outside the battery swap station; and in response to receiving a clear completion message from the battery control unit, causing the battery to leave the battery compartment, the clear completion message including information indicating that the clearing of the subtotal of the status information is complete. The method enables the battery to leave the battery swap station based on the battery's exit requirements. Before the battery leaves the battery swap station, the connection status between the battery and the battery compartment is determined. The battery will only leave the compartment if the connection is disconnected. Prior to the battery leaving the compartment, the previous subtotal of the battery's status outside the compartment is cleared to avoid misjudgment of the battery's status and facilitate the recording and storage of relevant information generated by the battery outside the station. This standardizes the battery exit process and improves the reliability and safety of battery exit.

[0015] In some embodiments, the battery further includes a switch, and determining whether the connection between the battery and the battery compartment is disconnected includes: in response to receiving a request from the battery to leave the battery swap station, determining whether the battery is in a charging state; and in response to the battery pack not being in a charging state, determining the connection state of the battery switch to determine whether the connection between the battery and the battery compartment is disconnected. Before the battery is removed from the compartment, a determination is made as to whether the battery is in a charging state and connected to the battery compartment. The battery is only allowed to be removed from the compartment when the battery is not in a charging state and disconnected from the battery compartment, thereby reducing the probability of safety hazards and improving the safety of the removal process.

[0016] In some embodiments, determining whether the battery is disconnected from the battery compartment further includes: in response to determining that the battery is in a charging state, causing a charging device in the battery compartment to stop charging the battery. Before the battery is removed from the compartment, if the battery is in a charging state, causing the charging device to stop charging the battery improves safety during the removal process.

[0017] In some embodiments, the clearing instruction also includes an instruction for instructing the clearing of battery fault information, and the clearing completion information also includes information indicating that the fault information has been cleared. During the battery removal process, if a fault occurs during removal (thus preventing the clearing of the fault information), resulting in a failure, the battery will be retried to correct the fault and remove the battery. If the fault information persists after several attempts, the battery is deemed to have failed to be removed, thereby reducing the probability of safety hazards and improving the safety of the removal process.

[0018] In some embodiments, the battery control unit includes a wakeup source interface. In response to receiving a purge completion message from the battery control unit, causing the battery to be removed from the battery compartment includes: in response to receiving the purge completion message from the battery control unit, causing a charging device in the battery compartment to stop sending a wakeup signal to the wakeup source interface to put the battery control unit into hibernation; and causing the battery to be removed from the battery compartment after a first time period has elapsed since the battery control unit was determined to be in hibernation. During the battery removal process, the battery control unit is put into hibernation to transfer the battery from the battery compartment. The battery is then removed from the battery compartment after a predetermined period of time has elapsed after the battery control unit has been in hibernation, thereby reducing the possibility of misjudgment and improving the reliability of the removal process.

[0019] In some embodiments, in response to receiving a purge completion message from the battery control unit, causing the charging device of the battery compartment to stop sending a wake-up signal to the wake-up source interface to put the battery control unit into hibernation includes: sending a leave request to the battery control unit in response to receiving the purge completion message from the battery control unit; and in response to receiving a leave request result from the battery control unit, causing the charging device of the battery compartment to stop sending a wake-up signal to the wake-up source interface to put the battery control unit into hibernation, wherein the leave request result is used to indicate that the battery pack can leave the battery compartment. Controlling the battery pack's departure from the battery compartment based on the leave request result improves the reliability of the exit process.

[0020] In some embodiments, after a first time period from when the battery control unit is determined to be dormant, removing the battery from the battery compartment includes: sending a removal instruction to a transfer device; and causing the transfer device to perform an operation to remove the battery from the battery compartment. During the battery removal process, the transfer device is controlled and used to transfer the battery from the battery compartment to a designated location, reducing reliance on manual transfer and improving the safety and accuracy of the transfer process.

[0021] An embodiment of the third aspect of the present application provides a control device for a battery entering a battery swap station, wherein the battery includes a battery control unit, and the battery swap station includes a battery compartment. The control device includes: a first module configured to switch the battery control unit to an in-station mode in response to the battery being connected to the battery compartment, wherein the in-station mode is used to instruct the battery control unit to operate within the battery swap station; a second module configured to send a clear instruction to the battery control unit in response to receiving battery information from the battery control unit, wherein the clear instruction includes an instruction for instructing to clear the subtotal status information of the battery's last operation within the battery swap station; and a third module configured to cause a charging device in the battery compartment to charge the battery in response to receiving a clear completion message from the battery control unit, wherein the clear completion message includes information indicating that the clearing of the subtotal status information is complete. The effect of this embodiment is the same as that of the corresponding method.

[0022] An embodiment of the fourth aspect of the present application provides a control device for a battery to leave a battery swap station, wherein the battery includes a battery control unit, the battery swap station includes a battery compartment, and the control device includes: a fourth module configured to, in response to receiving a request from the battery to leave the battery swap station, determine whether the connection between the battery and the battery compartment is disconnected; a fifth module configured to, in response to determining that the connection between the battery and the battery compartment is disconnected, send a clear instruction to the battery control unit, the clear instruction including an instruction for instructing to clear the subtotal status information of the battery's last operation outside the battery swap station; and a sixth module configured to, in response to receiving a clear completion message from the battery control unit, cause the battery to leave the battery compartment, the clear completion message including information for indicating that the clearing of the subtotal status information is complete. The effect of this embodiment is the same as that of the corresponding method.

[0023] In a fifth aspect, an embodiment of the present application provides a computing device comprising at least one processor and at least one memory communicatively coupled to the at least one processor. The at least one memory stores instructions that, when executed individually or collectively by the at least one processor, cause the computing device to perform the method described in the above embodiment.

[0045] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0046] During the use of power batteries, it is sometimes necessary to replace the batteries at a battery swap station, that is, to replace the power batteries in a low-power state with power batteries with full power. The power batteries in a low-power state are then stored at the battery swap station for charging and management.

[0047] Existing battery swap stations often require manual labor for battery replacement and charging. This lacks a standardized process for battery loading and unloading, resulting in a high reliance on manpower, the potential for misoperation, and low reliability. There's also a lack of reliable storage for information about power batteries both inside and outside the station, which can lead to data confusion and inaccurate battery status assessments, posing a safety hazard.

[0048] Therefore, a method is needed to control the entry and exit of batteries. This method standardizes the process of battery entry and exit, ensures that subsequent operations on batteries can be carried out normally after entering the warehouse, and that batteries can be unloaded normally when needed. Furthermore, this method can clear temporary records of batteries both inside and outside the station to accurately store relevant information about batteries inside and outside the station. This can improve the reliability of the battery replacement process, reduce reliance on manpower, and reduce the risk of safety issues.

[0049] The control method disclosed in the embodiment of the present application can be used, but is not limited to, in the process of replacing power batteries in vehicles, ships, aircraft, etc. According to the control method disclosed in the embodiment of the present application, the battery can be normally loaded and unloaded during the battery replacement process, thereby improving the reliability of the battery replacement process.

[0050] An embodiment of the present application provides a control method 100 for a battery to enter a battery swap station. The battery includes a battery control unit, and the battery swap station includes a battery compartment. Referring to FIG. 1 , the control method 100 includes:

[0051] Step 110, in response to the battery being connected to the battery compartment, the battery control unit is switched to the in-station mode, where the in-station mode is used to instruct the battery control unit to operate in the battery swap station.

[0052] Step 120: In response to receiving the battery information from the battery control unit, a clear instruction is sent to the battery control unit, where the clear instruction includes an instruction for instructing to clear the subtotal information of the battery's last operation in the battery swap station.

[0053] Step 130 : In response to receiving the clearing completion information from the battery control unit, the charging device in the battery compartment charges the battery. The clearing completion information includes information indicating that the clearing of the status subtotal information is completed.

[0054] In this article, the term "battery control unit" refers to the equipment module used to monitor, protect and control battery performance and safety.

[0055] The above control method 100 may be executed by a battery swap station control system.

[0056] During the battery swapping process, the battery is removed from the original installation location (for example, the vehicle) by a transfer device (for example, an AGV cart, etc.) and transported to the battery compartment of the battery swap station, and connected to the battery compartment through a connector. After determining that the battery is connected to the battery compartment, the battery control unit recognizes that the battery is in the battery swap station, and the battery control unit switches to the in-station mode. The in-station mode indicates the operations performed by the battery control unit in the battery swap station, for example, determining at least one of the charging energy subtotal information, charging energy cumulative information, discharge energy subtotal information, and discharge energy cumulative information of the battery in the battery swap station, sending a corresponding request to the battery swap station, receiving instructions from the battery swap station and performing corresponding actions, etc. In this article, "subtotal" refers to the record of status information (for example, charging energy, discharge energy, etc.) in the battery compartment at a single time, and "cumulative" refers to the record of status information accumulated in the battery compartment multiple times.

[0057] After the battery control unit switches to in-station mode, it sends battery information to the battery swap station. After receiving this information, the battery swap station sends a clear command to the battery control unit, instructing it to clear the subtotal information of the battery's last operation at the battery swap station and regenerate the relevant subtotal information for the current operation at the battery swap station.

[0058] In this article, "status subtotal information of operation in the battery swap station" may include information such as the battery subtotal charging energy in the station, the battery subtotal discharging energy in the station, and may also include other subtotal information of the battery in the station, which is not limited in this disclosure.

[0059] When the battery control unit is cleared, the charging device in the battery compartment starts charging the battery.

[0060] Control method 100 switches the battery control unit to in-station mode after the battery enters the station. Through communication between the battery control unit and the battery swap station, previously stored status subtotal information is cleared and relevant information is recalculated, improving the accuracy of data storage and reducing the possibility of status misjudgments due to uncleared data. After the clearing is completed, the battery is charged, standardizing the battery storage process and improving the reliability and safety of battery storage.

[0061] According to some embodiments of the present application, the in-station mode is used to indicate that the coding value of the battery control unit is updated to a coding value specific to the battery swap station, and the battery information includes a coding value specific to the battery swap station.

[0062] When the battery is not removed from its original installation location, the coding value of the battery control unit is the coding value corresponding to the original installation location. Taking the battery installed on the vehicle as an example, when the battery is in the vehicle, the coding value of the battery control unit corresponds to the vehicle, so as to facilitate communication and interaction between the battery control unit and the vehicle. After the battery is removed and transferred to the battery swap station, the coding value of the battery control unit will be updated to a coding value specific to the battery swap station. This coding value will be included in the battery information and sent to, for example, the charging device, which will forward it to the battery swap station.

[0063] For example, after the electronic control unit is awakened, it will identify, for example, a high level according to the wake-up source interface (this is caused by, for example, the charging device providing a wake-up signal to it) to determine whether to switch to the in-station mode. If the electronic control unit confirms the switch to the in-station mode, it will update its own code value to a code value specific to the battery swap station. If the electronic control unit cannot update the code value, the charging device will not be able to obtain battery information.

[0064] Update the coding value of the battery control unit to a coding value specific to the battery swap station. After the coding value is updated, the battery swap station can communicate and interact with the battery control unit without having to identify the coding value corresponding to the vehicle before the update, reducing the complexity of the operation and the risk of identification failure, and improving the reliability of battery storage.

[0065] According to some embodiments of the present application, the battery control unit includes a wake-up source interface, and step 110 includes:

[0066] The charging device sends a wake-up signal to the wake-up source interface to start the battery control unit and switch the battery control unit to the in-station mode.

[0067] After the battery is transferred to the battery compartment of the battery swap station, the charging device in the battery compartment sends a wake-up signal to the wake-up source interface of the battery control unit. The wake-up signal will, for example, cause the wake-up source interface to have a high level. Thus, the wake-up signal can start (i.e. wake up) the battery control unit for subsequent operations. At the same time, the battery control unit determines that the battery is in the battery swap station based on the wake-up signal and switches to the in-station mode.

[0068] By sending a wake-up signal to the wake-up source interface, the battery control unit wakes up and switches to in-station mode, improving the accuracy of battery status judgment. Furthermore, waking up and switching to in-station mode can be achieved through a single interface, improving the integration of the battery's internal circuit design and reducing space usage.

[0069] According to some embodiments of the present application, the operation of the battery control unit in the battery swap station includes determining at least one of the charging energy subtotal information, charging energy cumulative information, discharging energy subtotal information and discharging energy cumulative information of the battery in the battery swap station.

[0070] In this article, the term "charging energy subtotal information" is used to indicate the energy statistical information of the battery charged in the battery swap station. In one example, the "charging energy subtotal information" includes the charging energy information of the battery pack subtotal in the station. The term "charging energy cumulative information" is used to indicate the cumulative information of the charging energy of the battery in the battery swap station. The term "discharge energy subtotal information" is used to indicate the energy statistical information of the battery discharged in the battery swap station. In one example, the "discharge energy subtotal information" includes the discharge energy information of the battery pack subtotal in the station. The term "discharge energy cumulative information" is used to indicate the cumulative information of the discharge energy of the battery in the battery swap station.

[0071] In some embodiments, after each battery enters the station, upon receiving a clear command, the battery control unit will only clear the battery's charging energy subtotal and discharging energy subtotal information at the station and recalculate the subtotal information for this entry. The battery control unit will not clear the charging energy accumulation information and the discharging energy accumulation information, but will continue to accumulate the relevant information.

[0072] While the battery is in the station, the battery control unit will store relevant information to determine whether the battery status is normal, which improves the accuracy of data storage, can identify abnormal situations in a timely manner, and improve the safety of the battery storage process.

[0073] According to some embodiments of the present application, the control method 100 further includes:

[0074] While the charging device is charging the battery, the status of the battery is monitored.

[0075] In some embodiments, during the battery charging process, the battery swap station monitors the battery status in real time via a bus. In one example, the battery status is monitored via a Controller Area Network (CAN) bus.

[0076] During the battery charging process, the battery status is monitored in real time to determine whether the battery status is normal. This can quickly identify abnormal situations and improve the safety of the charging process.

[0077] This embodiment of the present application provides a control method 200 for a battery to leave a battery swap station. The battery includes a battery control unit, and the battery swap station includes a battery compartment. Referring to FIG. 2 , the control method 200 includes:

[0078] Step 210 : In response to receiving a request from the battery to leave the battery swap station, determining whether the connection between the battery and the battery compartment is disconnected.

[0079] Step 220: In response to determining that the connection between the battery and the battery compartment is disconnected, a clear instruction is sent to the battery control unit, where the clear instruction includes an instruction for instructing to clear the subtotal information of the battery's last operation outside the battery swap station.

[0080] Step 230 : In response to receiving the clearing completion information from the battery control unit, the battery is removed from the battery compartment. The clearing completion information includes information indicating that the clearing of the status subtotal information is completed.

[0081] The above control method 200 may be executed by a battery swap station control system.

[0082] In some embodiments, the battery's request to leave the battery swap station may include a user's request for the battery to be removed from the warehouse. In one example, the battery's request to leave the battery swap station is a battery replacement request sent by the user through an application.

[0083] When a request is received for the battery to leave the battery swap station, the system determines whether the battery is still connected to the battery compartment at the battery swap station. After confirming that the battery is disconnected from the battery compartment, the system sends a clear command to the battery control unit, instructing it to clear the subtotal of the battery's last operation outside the battery swap station.

[0084] In this article, "the subtotal information of the status of operation outside the battery swap station" may include the subtotal discharge energy of the battery pack outside the station, the subtotal recharging energy of the battery pack outside the station, the subtotal charging energy of the battery pack outside the station, the subtotal mileage of the battery pack, etc. It may also include other subtotal information of the battery outside the station, and this disclosure does not limit this.

[0085] After the battery control unit is cleared, remove the battery from the battery compartment.

[0086] Control method 200 ensures that batteries leave the battery swap station based on the battery's exit requirements. Before leaving the station, the connection between the battery and the battery compartment is determined. The battery will only leave the compartment if the connection is broken. Furthermore, prior to leaving the station, the previous off-station status subtotal is cleared to avoid misjudging the battery's status and facilitate storage of relevant information generated by the battery outside the station. This standardizes the battery exit process and improves the reliability and safety of battery exit.

[0087] According to some embodiments of the present application, the battery further includes a switch. Referring to FIG. 3 , step 210 includes:

[0088] Step 310 : In response to receiving a request from the battery to leave the battery swap station, determining whether the battery is in a charging state.

[0089] Step 320 , in response to the battery pack not being in a charging state, determining the connection state of the switch of the battery to determine whether the connection between the battery and the battery compartment is disconnected.

[0090] A switch is provided inside the battery to control the connection and disconnection between the battery and the battery compartment. In one example, the battery switch is a relay. Other types of devices for controlling the connection and disconnection between the battery and the battery compartment may also be used, and this disclosure is not limited thereto.

[0091] Before the battery leaves the station, it checks whether it is in a charging state. If it is not, it determines the battery's on / off status. The battery can only leave the station if the connection between the battery and the battery compartment is disconnected. If the connection between the battery and the battery compartment is not disconnected, the battery fails to leave the station.

[0092] In some examples, the electronic control unit sends the on / off status of the battery to the battery swap station control system, and the battery swap station determines whether the connection between the battery and the battery compartment is disconnected based on the on / off status sent by the battery.

[0093] The battery is only allowed to be removed from the compartment when it is not in a charging state and is disconnected from the battery compartment, which reduces the probability of safety hazards and improves the safety of the removal process.

[0094] According to some embodiments of the present application, step 210 further includes:

[0095] In response to determining that the battery is in a charging state, the charging device of the battery compartment stops charging the battery.

[0096] When receiving a request from the battery to leave the battery swap station, if the battery is still in a charging state, the charging device stops charging the battery. When the battery is not in a charging state, it is determined whether the connection between the battery and the battery compartment is disconnected.

[0097] Before the battery is shipped out of the warehouse, if the battery is in a charging state, the charging device will stop charging the battery, thereby improving the safety of the shipping process.

[0098] According to some embodiments of the present application, the clearing instruction further includes an instruction for instructing to clear the fault information of the battery, and the clearing completion information further includes information for indicating that the clearing of the fault information is completed.

[0099] That is to say, the clearing instruction sent by the battery swap station control system to the electronic control unit includes an instruction to clear the battery fault information. After receiving the instruction, the electronic control unit clears the fault information and feeds back the fault clearing result to the battery swap station control system.

[0100] During the battery's unloading process, if unloading fails due to incomplete fault clearing, the electronic control unit will clear the fault information and re-feed back the fault clearing result. The battery control unit will feedback the clearing completion information to the battery swap station control system. If the clearing completion information indicates that the fault information has been cleared, the battery swap station control system will proceed to the next step of the unloading preparation process. If the fault information fails after clearing several times in a row, it is determined that the battery unloading has failed and will not be re-loaded. In one example, if the fault information fails after clearing three times in a row, it is determined that the battery unloading has failed.

[0101] The number of times the battery fails to be removed from the storage compartment can be set according to the usage scenario, and this disclosure does not limit this.

[0102] If a fault occurs during the battery removal process (the fault message cannot be cleared), causing the removal process to fail, the system will retry to eliminate the fault and remove the battery. If the fault message persists after several attempts, the battery removal process is considered to have failed, reducing the possibility of safety hazards and improving the safety of the removal process.

[0103] According to some embodiments of the present application, the battery control unit includes a wake-up source interface. Referring to FIG. 4 , step 230 includes:

[0104] Step 410 , in response to receiving the clearing completion information from the battery control unit, the charging device of the battery compartment stops sending the wake-up signal to the wake-up source interface to put the battery control unit into sleep mode.

[0105] Step 420 : After a first time period from when the battery control unit is determined to be dormant, remove the battery from the battery compartment.

[0106] When the battery control unit has completed clearing the subtotal information of the battery's operation status outside the battery swap station, the charging device no longer sends a wake-up signal to the wake-up source interface, causing the battery control unit to sleep. After waiting for a certain period of time, the battery is transferred out of the battery compartment.

[0107] The waiting time can be set according to the usage scenario. In one example, the waiting time is 5 seconds.

[0108] During the battery removal process, the battery control unit is put into sleep mode and waits for a certain period of time before the battery leaves the battery compartment, thereby reducing the possibility of damage to the battery due to misjudgment and improving the reliability of the removal process.

[0109] According to some embodiments of the present application, step 410 includes:

[0110] In response to receiving the clearing completion information from the battery control unit, sending a leave request to the battery control unit; and

[0111] In response to receiving a leave request result from the battery control unit, the charging device of the battery compartment stops sending a wake-up signal to the wake-up source interface to put the battery control unit into sleep mode. The leave request result is used to indicate that the battery can leave the battery compartment.

[0112] After the information is cleared, the battery swap station control system sends a departure request to the electronic control unit to confirm whether the electronic control unit is ready to leave the battery compartment. The battery control unit then determines the battery status. If the battery is fault-free or has a fault that allows it to leave the battery compartment, the battery control unit sends a departure request result, indicating that the battery can leave the battery compartment. After receiving the departure request result, the charging device stops sending wake-up signals to the wake-up source interface, putting the battery control unit into hibernation to execute the battery exit.

[0113] The battery is controlled to leave the battery compartment according to the departure request result fed back by the battery control unit, thereby improving the reliability of the battery exit process.

[0114] According to some embodiments of the present application, referring to FIG. 5 , step 420 includes:

[0115] Step 510: Send a leave instruction to the transfer device.

[0116] Step 520: Enable the transfer device to remove the battery from the battery compartment.

[0117] Transfer equipment is used to transport batteries both when they enter and leave a battery swap station. By sending a departure command to the transfer equipment, it transfers the battery from the battery compartment to the designated location where it is needed.

[0118] In some embodiments, the transfer equipment includes an automatic guided vehicle (AGV), an automatic handling robot, etc., which is not limited in the present disclosure.

[0119] During the battery out-of-warehouse process, the transfer equipment is controlled and used to transfer the batteries from the battery warehouse to the designated location, reducing the reliance on manual transfer, standardizing the battery out-of-warehouse process, and improving the safety and accuracy of the transfer process.

For the sake of brevity, these are not further described here.

[0144] An embodiment of the present application further provides a computer-readable storage medium having instructions stored thereon. When the instructions are executed by a processor, the processor executes the method in any of the above embodiments.

[0145] Computer-readable storage media includes volatile and nonvolatile, removable and non-removable media implemented by any method or technology for storage of information, such as computer-readable instructions, data structures, program modules, or other data.

[0146] An embodiment of the present application further provides a computer program product, comprising instructions, which, when executed by a processor, causes the processor to execute a method as described in any of the above embodiments.

[0147] A specific embodiment of the present application is described below. It should be understood that this specific embodiment is described for illustrative purposes only and should not be construed as limiting the present application.

[0148] As shown in Figure 1, when a battery is removed by an automated guided vehicle and transferred to a battery swap station, where it is connected to the station's battery compartment, the station control system sends a wake-up signal command to the battery compartment's charger. Upon receiving this command, the charger provides low-voltage power to the battery control unit and sends a wake-up signal to the battery control unit's wake-up source interface. Upon receiving the wake-up signal, the battery control unit wakes up and switches to in-station mode.

[0149] In the in-station mode, the battery control unit's coding value is updated to a coding value specific to the battery swap station. The battery control unit sends battery information including the updated coding value to the battery swap station.

[0150] After receiving the battery information, the battery swap station sends a command to the battery control unit requesting that the subtotal of the battery's last operation within the station be cleared. Upon receiving this clear command, the battery control unit acknowledges receipt of the clear request and clears the subtotal of the station's operation status. When the clear is complete, the battery control unit sends a clear completion message.

[0151] After receiving the clearing completion information, the battery swap station enables the charger to charge the battery.

[0152] As shown in Figure 2, when the battery swap station receives a request to leave the station, it determines whether the battery is charging. If the battery is still charging, the charger stops charging the battery. If the battery is not charging, it determines whether the main positive and negative relays in the battery are disconnected based on the main positive and negative relay status information sent by the battery control unit.

[0153] Upon determining that the battery's main positive and negative relays are disconnected, the battery swap station sends a request to the battery control unit (BCU) to clear the fault information and the subtotal of the battery's last off-station operation. Upon receiving the clear command, the BCU acknowledges receipt and clears the fault information and subtotal of off-station operation status. When the clear is complete, the BCU sends a clear completion message.

[0154] After receiving the clearing completion message, the battery swap station sends a battery release request to the battery control unit. After receiving the release request, the battery control unit responds with a confirmation instruction. If the battery is allowed to be released, it responds with the battery release request result.

[0155] After receiving the battery out-of-warehouse request result, the battery swap station turns off the charger switch and stops the charger from sending wake-up signals to the wake-up source interface of the battery control unit, so that the battery control unit stores data and enters a dormant state.

[0156] The battery swap station determines that the life frame of the battery control unit has stopped and waits for 5 seconds before executing the battery removal.

[0157] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein.

In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
