[0001] The present application relates to the technical field of batteries, and in particular, to a control method and device for a battery to enter a battery swapping station, a control method and device for a battery to leave a battery swapping station, a computing device, a battery swapping station, a computer-readable storage medium, and a computer program product. Background Art

[0002] Energy conservation and emission reduction are the keys to the sustainable development of the automotive industry. Electric vehicles have become an important part of the sustainable development of the automotive industry due to their advantages of energy conservation and environmental protection. For electric vehicles, battery technology is an important factor related to their development.

[0003] When it is necessary to use a battery swapping station to replace and charge a battery, it is often necessary for manual operation of the battery entering and leaving the warehouse process, with low reliability and potential safety hazards. Summary of the Invention

[0004] 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 to enter a battery swapping station, a control method and control device for a battery to leave a battery swapping station, a computing device, a battery swapping station, a computer-readable storage medium, and a computer program product to alleviate, mitigate, or eliminate problems in related technologies.

[0005] An embodiment of the first aspect of the present application provides a control method for a battery to enter a battery swapping station. The battery includes a battery control unit, and the battery swapping station includes a battery compartment. The control method includes: in response to the connection between the battery and the battery compartment, switching the battery control unit to the in-station mode, where the in-station mode is used to instruct the battery control unit to operate within the battery swapping station; in response to receiving battery information from the battery control unit, sending a clearing instruction to the battery control unit, where the clearing instruction includes an instruction for instructing to clear the status summary information of the battery's previous operation within the battery swapping station; and in response to receiving the clearing completion information from the battery control unit, enabling the charging device of the battery compartment to charge the battery, where the clearing completion information includes information for indicating the completion of clearing the status summary information.

[0006] In the technical solution of the embodiment of the present application, a control method for a battery to enter a battery swapping station is provided. This method enables the battery to be charged normally after entering the station, and at the same time clears the previous status information after the battery enters the station to avoid misjudging the battery status and facilitate recording and storing relevant information generated by the battery within the station. This can standardize the process of the battery entering the warehouse and improve the reliability and safety of the battery entering the warehouse.

[0007] In some embodiments, the in-station mode is used to indicate that the encoded value of the battery control unit is updated to an encoded value specific to the battery swapping station, and the battery information includes the encoded value specific to the battery swapping station. When the battery has not entered the battery swapping station, the battery control unit has an encoded value. After the battery enters the station, the encoded value of the battery control unit is updated to the encoded value specific to the battery swapping station, enabling the battery swapping station to communicate and interact with the battery control unit normally based on this specific encoded value, thereby improving the reliability of battery warehousing.

[0008] In some embodiments, the battery control unit includes a wake-up source interface. Enabling the battery control unit to switch to the in-station mode includes: causing the charging device to send a wake-up signal to the wake-up source interface to start the battery control unit and cause the battery control unit to switch to the in-station mode. The charging device sending a wake-up signal to the wake-up source interface wakes up the battery control unit and determines that the battery is in the station based on this wake-up signal, achieving an accurate judgment of the battery state. That is to say, through a single wake-up signal, the functions of waking up the electronic control unit and switching its state are realized, thus simplifying the control process.

[0009] In some embodiments, the operations of the battery control unit within the battery swapping station include 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 within the battery swapping station. During the period when the battery is in the station, the battery control unit stores the relevant information to facilitate determining whether the battery state is normal.

[0010] In some embodiments, the control method further includes: monitoring the state of the battery during charging by the charging device. Monitoring the state of the battery during charging can promptly identify abnormal situations and improve the safety of the charging process.

[0011] An embodiment of the second aspect of the present application provides a control method for a battery to leave a battery swapping station. The battery includes a battery control unit, and the battery swapping station includes a battery compartment. The control method includes: in response to receiving a request for the battery to leave the battery swapping 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 clearing instruction to the battery control unit, the clearing instruction including an instruction for indicating to clear the status summary information of the battery's previous operation outside the battery swapping station; and in response to receiving the clearing completion information from the battery control unit, allowing the battery to leave the battery compartment, the clearing completion information including information for indicating that the status summary information has been cleared. This method enables the battery to leave the battery swapping station according to the requirement of the battery leaving the compartment. Before the battery leaves the battery swapping station, the connection status between the battery and the battery compartment is judged, and the battery will only leave the compartment when the connection is disconnected. At the same time, before the battery leaves the compartment, the previous off-station status summary information is cleared to avoid misjudging the status of the battery and facilitate the recording and storage of relevant information generated by the battery outside the station. This can standardize the process of the battery leaving the compartment and improve the reliability and safety of the battery leaving the compartment.

[0012] 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 for the battery to leave the battery swapping 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's switch to determine whether the connection between the battery and the battery compartment is disconnected. Before the battery leaves the compartment, it is determined whether the battery is in a charging state and whether it is connected to the battery compartment. The battery is only allowed to leave the compartment when the battery is not in a charging state and is disconnected from the battery compartment, reducing the probability of potential safety hazards and improving the safety of the process of leaving the compartment.

[0013] In some embodiments, determining whether the connection between the battery and the battery compartment is disconnected further includes: in response to determining that the battery is in a charging state, stopping the charging device of the battery compartment from charging the battery. Before the battery leaves the compartment, if the battery is in a charging state, the charging device is stopped from charging the battery, improving the safety of the process of leaving the compartment.

[0014] In some embodiments, the clearing instruction further includes an instruction for indicating to clear the fault information of the battery, and the clearing completion information further includes information for indicating that the fault information has been cleared. During the process of the battery leaving the compartment, if there is a fault during the process of leaving the compartment (and the fault information cannot be cleared) resulting in the failure of leaving the compartment, an attempt will be made to troubleshoot the fault again to leave the compartment. If there is still fault information after several attempts, it is determined that the battery leaving the compartment fails, reducing the probability of potential safety hazards and improving the safety of the process of leaving the compartment.

[0015] In some embodiments, the battery control unit includes a wake-up source interface. In response to receiving the clear completion information from the battery control unit, causing the battery to leave the battery compartment includes: in response to receiving the clear completion information from the battery control unit, causing the charging device in the battery compartment to stop sending a wake-up signal to the wake-up source interface, so that the battery control unit goes to sleep; and after a first time period from determining that the battery control unit is asleep, causing the battery to leave the battery compartment. During the process of the battery leaving the compartment, causing the battery control unit to go to sleep to transfer the battery out of the battery compartment and waiting for a certain time after the battery control unit goes to sleep before causing the battery to leave the battery compartment reduces the possibility of misjudgment and improves the reliability of the process of leaving the compartment.

[0016] In some embodiments, in response to receiving the clear completion information from the battery control unit, causing the charging device in the battery compartment to stop sending a wake-up signal to the wake-up source interface, so that the battery control unit goes to sleep includes: in response to receiving the clear completion information from the battery control unit, sending a leave request to the battery control unit; and in response to receiving the leave request result from the battery control unit, causing the charging device in the battery compartment to stop sending a wake-up signal to the wake-up source interface, so that the battery control unit goes to sleep, where the leave request result is used to indicate that the battery pack can leave the battery compartment. Controlling the battery to leave the battery compartment according to the leave request result improves the reliability of the process of leaving the compartment.

[0017] In some embodiments, after a first time period from determining that the battery control unit is asleep, causing the battery to leave the battery compartment includes: sending a leave instruction to the transfer device; and causing the transfer device to perform an operation of leaving the battery from the battery compartment. During the process of the battery leaving the compartment, the transfer device will be controlled to transfer the battery from the battery compartment to a designated location, reducing the dependence on manual transfer and improving the safety and accuracy of the transfer process.

[0018] An embodiment of the third aspect of the present application provides a control device for a battery to enter a battery swapping station. The battery includes a battery control unit, and the battery swapping station includes a battery compartment. The control device includes: a first module configured to, in response to the battery being connected to the battery compartment, cause the battery control unit to switch to the in-station mode, where the in-station mode is used to indicate the operations of the battery control unit in the battery swapping station; a second module configured to, in response to receiving the battery information from the battery control unit, send a clear instruction to the battery control unit, where the clear instruction includes an instruction for indicating clearing the status summary information of the battery's previous operation in the battery swapping station; and a third module configured to, in response to receiving the clear completion information from the battery control unit, cause the charging device in the battery compartment to charge the battery, where the clear completion information includes information for indicating that the status summary information has been cleared. The effect of this embodiment is the same as that of the corresponding method.

[0019] An embodiment of the fourth aspect of the present application provides a control device for a battery to leave a battery swapping station. The battery includes a battery control unit, and the battery swapping station includes a battery compartment. The control device includes: a fourth module configured to determine whether the connection between the battery and the battery compartment is disconnected in response to receiving a request for the battery to leave the battery swapping station; a fifth module configured to send a clearing instruction to the battery control unit in response to determining that the connection between the battery and the battery compartment is disconnected, the clearing instruction including an instruction for instructing to clear the status summary information of the battery's last operation outside the battery swapping station; and a sixth module configured to cause the battery to leave the battery compartment in response to receiving the clearing completion information from the battery control unit, the clearing completion information including information for indicating that the status summary information has been cleared. The effects of this implementation scheme are the same as those of the corresponding method.

[0020] An embodiment of the fifth aspect of the present application provides a computing device, which includes at least one processor; and at least one memory communicatively connected to the at least one processor. The at least one memory stores instructions that, when executed by the at least one processor alone or jointly, cause the computing device to execute the method in the above embodiments.

[0042] Currently, from the perspective of the development of the market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydraulic, thermal, wind, and solar power stations, but also widely used in electric transportation such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0043] During the use of power batteries, it is sometimes necessary to replace the batteries through a battery swapping station, that is, to replace the power battery in a power-depleted state with a fully charged power battery, and store the power-depleted power battery in the battery swapping station for charging and management.

[0044] In existing battery swapping stations, it is often necessary for manual labor to perform operations such as battery replacement and charging. There is a lack of a standardized process for battery entry and exit from the warehouse, with a high degree of dependence on human labor, and there is a possibility of misoperation, resulting in low reliability. For the relevant information of power batteries inside and outside the battery swapping station, there is also a lack of a reliable storage method, which may lead to confusion in stored data, resulting in inaccurate judgment results of battery status and certain potential safety hazards.

[0045] Therefore, a control method for battery entry and exit from the warehouse is needed to standardize the process of battery entry and exit from the warehouse, enabling subsequent operations on the battery to be carried out normally after the battery enters the warehouse, enabling the battery to exit the warehouse normally when needed, and clearing the temporary record information of the battery inside and outside the station, so as to facilitate the accurate storage of relevant information of the battery inside and outside the station. This can improve the reliability of the battery swapping process, reduce the dependence on human labor, and reduce the risk of safety problems.

[0046] The control method disclosed in the embodiments of the present application can be but is not limited to being used in the battery swapping process of power batteries for vehicles, ships, aircraft, etc. According to the control method disclosed in the embodiments of the present application, the battery can enter and exit the warehouse normally during the battery swapping process, improving the reliability of the battery swapping process.

[0047] The embodiments of the present application provide a control method 100 for a battery to enter a battery swapping station. The battery includes a battery control unit, and the battery swapping station includes a battery warehouse. Please refer to Figure 1 , and the control method 100 includes:

[0048] Step 110, in response to the connection between the battery and the battery warehouse, switch the battery control unit to the in-station mode, and the in-station mode is used to instruct the operations of the battery control unit inside the battery swapping station.

[0049] Step 120, in response to receiving battery information from the battery control unit, send a clearing instruction to the battery control unit. The clearing instruction includes an instruction for instructing to clear the status summary information of the battery's previous operation inside the battery swapping station.

[0050] Step 130, in response to receiving the clearing completion information from the battery control unit, make the charging device of the battery warehouse charge the battery. The clearing completion information includes information for indicating the completion of clearing the status summary information.

[0051] In this document, the term "battery control unit" refers to a device module used to monitor, protect, and control battery performance and safety.

[0052] The above control method 100 can be executed by the battery swapping station control system.

[0053] During the battery swapping process, the battery is removed from its original installation location (e.g., a vehicle) by a transfer device (e.g., an AGV cart, etc.) and transported into the battery storage of the battery swapping station, and connected to the battery storage through a connector. When it is determined that the battery is connected to the battery storage, the battery control unit recognizes that the battery is within the battery swapping station, and at this time, the battery control unit switches to the in-station mode. The in-station mode indicates operations performed by the battery control unit within the battery swapping station, such as determining at least one of the following: the cumulative charging energy information, the cumulative charging energy total information, the cumulative discharging energy information, and the cumulative discharging energy total information of the battery within the battery swapping station, sending corresponding requests to the battery swapping station, receiving instructions from the battery swapping station, and performing corresponding actions, etc. In this document, "subtotal" refers to the recording of the status information (e.g., charging energy, discharging energy, etc.) of a single time within the battery storage, while "cumulative" refers to the recording of the status information accumulated multiple times within the battery storage.

[0054] After the battery control unit switches to the in-station mode, it sends battery information to the battery swapping station. After receiving this battery information, the battery swapping station sends a clearing instruction to the battery control unit, causing the battery control unit to clear the subtotal information of the previous operation of the battery within the battery swapping station and regenerate the relevant subtotal information for the current operation within the battery swapping station.

[0055] In this document, the "subtotal information of the operation status within the battery swapping station" may include information such as the subtotal charging energy within the station of the battery, the subtotal discharging energy within the station of the battery, etc., and may also include other subtotal information of the battery in the in-station situation. The present disclosure does not limit this.

[0056] After the battery control unit finishes clearing, the charging device of the battery storage starts charging the battery.

[0057] The control method 100 enables the battery control unit to switch to the in-station mode after the battery enters the station. Through the communication interaction between the battery control unit and the battery swapping station, the previously stored subtotal information is cleared and relevant information is re-counted, improving the accuracy of data storage and reducing the possibility of misjudgment of the status caused by uncleared data. After the clearing is completed, the battery is charged, standardizing the process of the battery entering the storage and improving the reliability and safety of the battery entering the storage.

[0058] According to some embodiments of the present application, the in-station mode is used to indicate updating the coding value of the battery control unit to a coding value specific to the battery swapping station, and the battery information includes the coding value specific to the battery swapping station.

[0059] When the battery is not removed from its original installation location, the encoded value of the battery control unit is the encoded value corresponding to the original installation location. Taking a battery installed in a vehicle as an example, when the battery is in the vehicle, the encoded value of the battery control unit corresponds to the vehicle to facilitate communication and interaction between the battery control unit and the vehicle. When the battery is removed and transferred to a swapping station, the encoded value of the battery control unit will be updated to an encoded value specific to the swapping station. This encoded value will be included in the battery information and sent to, for example, a charging device, which will forward it to the swapping station.

[0060] For example, after the electronic control unit is awakened, the electronic control unit will recognize, for example, a high level according to the wake-up source interface (which is caused, for example, by 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 encoded value to an encoded value specific to the swapping station. If the electronic control unit fails to update the encoded value, the charging device will be unable to obtain the battery information.

[0061] Updating the encoded value of the battery control unit to an encoded value specific to the swapping station allows the swapping station to communicate and interact with the battery control unit without having to recognize the encoded value corresponding to the vehicle before the update, reducing the complexity of operations and the risk of recognition failures, and improving the reliability of battery storage in the warehouse.

[0062] According to some embodiments of the present application, the battery control unit includes a wake-up source interface, and step 110 includes:

[0063] Cause the charging device to send 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.

[0064] After the battery is transferred to the battery warehouse of the swapping station, the charging device in the battery warehouse sends a wake-up signal to the wake-up source interface of the battery control unit. This 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 swapping station based on the wake-up signal and switches to the in-station mode.

[0065] By sending a wake-up signal to the wake-up source interface, the battery control unit is awakened and switched to the in-station mode, improving the accuracy of battery status judgment. At the same time, the wake-up function and the switch to the in-station mode can be achieved through only one interface, improving the integration of the internal circuit design of the battery and reducing the occupied space.

[0066] According to some embodiments of the present application, the operations of the battery control unit in the battery swapping station include 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 swapping station.

[0067] As used herein, the term "charging energy subtotal information" is used to indicate the energy statistical information of the current charging of the battery in the battery swapping station. In one example, the "charging energy subtotal information" includes the charging energy information of the battery pack in the station. The term "charging energy cumulative information" is used to indicate the cumulative information of the charging energy of the battery during previous charging in the battery swapping station. The term "discharging energy subtotal information" is used to indicate the energy statistical information of the current discharging of the battery in the battery swapping station. In one example, the "discharging energy subtotal information" includes the discharging energy information of the battery pack in the station. The term "discharging energy cumulative information" is used to indicate the cumulative information of the discharging energy of the battery during previous discharging in the battery swapping station.

[0068] In some embodiments, after each time the battery enters the station, when receiving a clearing instruction, the battery control unit only clears the charging energy subtotal information and the discharging energy subtotal information of the battery in the battery swapping station, and re-statistics the subtotal information for this entry. The battery control unit does not clear the charging energy cumulative information and the discharging energy cumulative information, but continues to accumulate the relevant information.

[0069] During the period when the battery is in the station, the battery control unit stores the relevant information to determine whether the battery state is normal, improves the accuracy of data storage, and can identify abnormal situations in a timely manner, improving the safety of the battery entering the warehouse process.

[0070] According to some embodiments of the present application, the control method 100 further includes:

[0071] Monitoring the state of the battery during the charging of the battery by the charging device.

[0072] In some embodiments, during the charging process of the battery, the battery swapping station monitors the battery state in real time through a bus. In one example, the battery state is monitored through a CAN (Controller Area Network) bus.

[0073] During the charging process of the battery, monitoring the battery state in real time and determining whether the battery state is normal can quickly identify abnormal situations and improve the safety of the charging process.

[0074] Embodiments of the present application provide a control method 200 for a battery to leave a battery swapping station. The battery includes a battery control unit, and the battery swapping station includes a battery compartment. Please refer to Figure 2 , the control method 200 includes:

[0075] Step 210, in response to receiving a request for the battery to leave the battery swapping station, determine whether the connection between the battery and the battery compartment is disconnected.

[0076] Step 220, in response to determining that the connection between the battery and the battery compartment is disconnected, send a clearing instruction to the battery control unit, where the clearing instruction includes an instruction for indicating to clear the status subtotal information of the battery's previous operation outside the battery swapping station.

[0077] Step 230, in response to receiving the clearing completion information from the battery control unit, cause the battery to leave the battery compartment, where the clearing completion information includes information for indicating that the status subtotal information has been cleared.

[0078] The above control method 200 can be executed by the battery swapping station control system.

[0079] In some embodiments, the request for the battery to leave the battery swapping station may include the user's demand for the battery to leave the compartment. In one example, the request for the battery to leave the battery swapping station is the user's demand for battery replacement sent through an application.

[0080] When receiving the request for the battery to leave the battery swapping station, it is necessary to determine whether the battery is still connected to the battery compartment of the battery swapping station. After determining that the connection between the battery and the battery compartment is disconnected, send a clearing instruction to the battery control unit to cause the battery control unit to clear the status subtotal information of the battery's previous operation outside the battery swapping station.

[0081] In this document, the "status subtotal information of the operation outside the battery swapping station" may include information such as the subtotal off-station discharge energy of the battery pack, the subtotal off-station recharge energy of the battery pack, the subtotal off-station plug-in charging energy of the battery pack, the subtotal mileage of the battery pack, etc., and may also include other subtotal information of the battery in the off-station situation. The present disclosure does not limit this.

[0082] After the battery control unit completes the clearing, cause the battery to leave the battery compartment.

[0083] The control method 200 enables the battery to leave the battery swapping station according to the demand for the battery to leave the compartment. Before the battery leaves the battery swapping station, the connection status between the battery and the battery compartment is judged. The battery will only leave the compartment when the connection is disconnected. At the same time, before the battery leaves the compartment, the previous off-station status subtotal information is cleared to avoid misjudging the battery status and facilitate storing the relevant information generated by the battery outside the station. This can standardize the process of the battery leaving the compartment and improve the reliability and safety of the battery leaving the compartment.

[0084] According to some embodiments of the present application, the battery further includes a switch. Please refer to Figure 3 , Step 210 includes:

[0085] Step 310, in response to receiving a request for the battery to leave the battery swapping station, determine whether the battery is in a charging state.

[0086] Step 320: In response to the battery pack not being in a charging state, determine the connection state of the switch of the battery to determine whether the connection between the battery and the battery compartment is disconnected.

[0087] A switch is provided inside the battery to control the conduction and disconnection between the battery and the battery compartment. In one example, the switch of the battery is a relay. Other forms of devices for controlling the on / off between the battery and the battery compartment can also be used, and the present disclosure does not limit this.

[0088] Before the battery exits the compartment, determine whether the battery is in a charging state. When the battery is not in a charging state, determine the switch state of the battery. Only when the connection between the battery and the battery compartment is disconnected can the battery leave the battery swapping station. In response to the connection between the battery and the battery compartment not being disconnected, the battery fails to leave the battery swapping station.

[0089] In some examples, the electronic control unit sends the switch state of the battery to the battery swapping station control system, and the battery swapping station determines whether the connection between the battery and the battery compartment is disconnected based on the switch state sent by the battery.

[0090] Allowing the battery to exit the compartment only when the battery is not in a charging state and is disconnected from the battery compartment reduces the probability of potential safety hazards and improves the safety of the process of exiting the compartment.

[0091] According to some embodiments of the present application, step 210 further includes:

[0092] In response to determining that the battery is in a charging state, stop the charging device of the battery compartment from charging the battery.

[0093] When receiving a request for the battery to leave the battery swapping station, if the battery is still in a charging state, stop the charging device from charging the battery. When the battery is not in a charging state, determine whether the connection between the battery and the battery compartment is disconnected.

[0094] Before the battery exits the compartment, if the battery is in a charging state, stop the charging device from charging the battery to improve the safety of the process of exiting the compartment.

[0095] According to some embodiments of the present application, the clear instruction further includes an instruction for instructing to clear the fault information of the battery, and the clear completion information further includes information for indicating that the fault information has been cleared.

[0096] That is to say, the clear instruction sent by the battery swapping station control system to the electronic control unit includes an instruction for clearing the fault information of the battery. After receiving this instruction, the electronic control unit clears the fault information and feeds back the fault clearing result to the battery swapping station control system.

[0097] During the process of the battery leaving the bin, if the bin exit fails due to incomplete fault clearance, the electronic control unit will clear the fault information and re - feedback the fault clearance result. The battery control unit feeds back the clearance completion information to the sub - station control system. If the clearance completion information indicates that the fault information has been cleared, the sub - station control system will proceed to the next bin - exit preparation process. If the fault information fails to be cleared after several consecutive attempts, it is determined that the battery bin exit fails, and the bin exit will not be attempted again. In one example, if the fault information fails to be cleared after 3 consecutive attempts, it is determined that the battery bin exit fails.

[0098] The number of times to determine the failure of the battery bin exit can be set according to the usage scenario, and the present disclosure does not limit this.

[0099] During the process of the battery leaving the bin, if the bin exit fails due to a fault (and the fault information cannot be cleared), an attempt will be made again to troubleshoot the fault for the bin exit. If the fault information still exists after several attempts, it is determined that the battery bin exit fails, reducing the probability of potential safety hazards and improving the safety of the bin - exit process.

[0100] According to some embodiments of the present application, the battery control unit includes a wake - up source interface. Please refer to Figure 4 , step 230 includes:

[0101] Step 410, in response to receiving the clearance completion information from the battery control unit, causing the charging device of the battery bin to stop sending a wake - up signal to the wake - up source interface, so as to put the battery control unit into sleep.

[0102] Step 420, after a first time period from determining that the battery control unit is in sleep, causing the battery to leave the battery bin.

[0103] When the battery control unit has completed clearing the status summary information of the battery's operation outside the sub - station, the charging device no longer sends a wake - up signal to the wake - up source interface, putting the battery control unit into sleep. After waiting for a certain time, the battery is transferred out of the battery bin.

[0104] The waiting time can be set according to the usage scenario. In one example, the waiting time is 5 s.

[0105] During the process of the battery leaving the bin, putting the battery control unit into sleep and waiting for a certain time before the battery leaves the battery bin reduces the possibility of misjudgment causing damage to the battery and improves the reliability of the bin - exit process.

[0106] According to some embodiments of the present application, step 410 includes:

[0107] In response to receiving the clearance completion information from the battery control unit, sending a leave request to the battery control unit; and

[0108] In response to receiving the departure request result from the battery control unit, the charging device in the battery compartment is made to stop sending the wake-up signal to the wake-up source interface, so that the battery control unit goes into dormancy, and the departure request result is used to indicate that the battery can leave the battery compartment.

[0109] After the information is cleared, the swapping 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. Then, the battery control unit judges the battery state. When the battery has no faults or there are faults that allow 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 the wake-up signal to the wake-up source interface, and the battery control unit goes into dormancy to perform the battery out-of-compartment operation.

[0110] Controlling the battery to leave the battery compartment according to the departure request result fed back by the battery control unit improves the reliability of the battery out-of-compartment process.

[0111] According to some embodiments of the present application, please refer to Figure 5 , step 420 includes:

[0112] Step 510, sending a departure instruction to the transfer device.

[0113] Step 520, making the transfer device perform an operation to make the battery leave the battery compartment.

[0114] During the process of the battery entering and leaving the swapping station, the transfer device is used to transport the battery. By sending a departure instruction to the transfer device, the transfer device transfers the battery from the battery compartment to a designated location where the battery is needed.

[0115] In some embodiments, the transfer device includes an Automated Guided Vehicle (AGV), an automatic handling robot, etc., and the present disclosure does not limit this.

[0116] During the battery out-of-compartment process, the transfer device is controlled to transfer the battery from the battery compartment to a designated location, reducing the dependence on manual transfer, standardizing the battery out-of-compartment process, and improving the safety and accuracy of the transfer process.

[0139] An embodiment of the present application also provides a battery swapping station, comprising: the control device 600 in the above embodiment, or the control device 700 in the above embodiment, or the computing device 800 in the above embodiment.

[0140] In some embodiments, the battery swapping station includes facilities for centrally storing and charging the batteries used by electric vehicles and performing services such as battery swapping for electric vehicles. The battery swapping station includes the control device 600 in the above embodiment, or the control device 700 in the above embodiment, or the computing device 800 in the above embodiment.

[0143] An embodiment of the present application also provides a computer program product, comprising instructions, and when the instructions are executed by a processor, the processor is caused to execute the method in any of the above embodiments.

[0144] 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 a limitation of the present application.

[0145] As Figure 1 shown, when the battery is removed by the automated guided vehicle and transferred to the battery swapping station and connected to the battery compartment of the battery swapping station, the battery swapping station control system sends a command to provide a wake-up signal to the charger in the battery compartment. After receiving this command, the charger supplies low-voltage power to the battery control unit and sends a wake-up signal to the wake-up source interface of the battery control unit. After receiving the wake-up signal, the battery control unit is awakened and switches to the in-station mode.

[0146] In the in-station mode, the encoded value of the battery control unit is updated to the encoded value specific to the battery swapping station. The battery control unit sends the battery information including the updated encoded value to the battery swapping station.

[0147] After receiving the battery information, the battery swapping station sends an instruction to the battery control unit to request clearing the status summary information of the battery's previous operation in the battery swapping station. After receiving this clearing instruction, the battery control unit feeds back an instruction to confirm receiving the clearing request and clears the status summary information of the in-station operation. When the clearing is completed, the battery control unit sends a clearing completion message.

[0148] After receiving this clearing completion message, the battery swapping station makes the charger charge the battery.

[0149] As Figure 2 shown, when the battery swapping station receives a request for the battery to leave the battery swapping station, it determines whether the battery is in a charging state. If the battery is still in a charging state, the charger is made to stop charging the battery. When the battery is not in a charging state, it is determined whether the main positive relay and the main negative relay in the battery are disconnected based on the status information of the main positive relay and the main negative relay sent by the battery control unit.

[0150] When it is determined that the main positive relay and the main negative relay in the battery are in a disconnected state, the battery swapping station sends an instruction to the battery control unit to request clearing the fault information and an instruction to request clearing the status summary information of the battery's previous operation outside the battery swapping station. After receiving the clearing instruction, the battery control unit feeds back an instruction to confirm receiving the clearing request and clears the fault information and the status summary information of the out-of-station operation. When the clearing is completed, the battery control unit sends a clearing completion message.

[0151] After receiving the clearing completion message, the battery swapping station sends a request for the battery to leave the compartment to the battery control unit. After receiving this out-of-compartment request, the battery control unit feeds back an instruction to confirm receiving the out-of-compartment request. When the battery permits leaving the compartment, it feeds back the result of the battery out-of-compartment request.

[0152] After receiving the battery out-of-warehouse request result, the battery swapping station disconnects the switch of the charger and stops the charger from sending a wake-up signal to the wake-up source interface of the battery control unit, causing the battery control unit to store data and enter the sleep state.

[0153] After the battery swapping station determines that the life frame of the battery control unit stops and waits for 5 s, it executes the battery out-of-warehouse operation.

[0154] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features. These modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
