Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a battery replacement control method, device, mobile terminal, medium and program product. Background Art

[0002] 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.

[0003] The development of new energy technologies has placed higher demands on electric vehicles, such as longer driving range and faster charging speeds. Consequently, battery swapping has emerged, allowing electric vehicle batteries to be replaced at battery swap stations. Through communication between the electric vehicle and the battery swap station, the battery can be removed from the electric vehicle and replaced with a battery stored at the station. However, if communication between the electric vehicle and the battery swap station fails, the battery swap process will not proceed normally, resulting in failure. Summary of the Invention

[0004] This application aims to at least solve the technical problem in the background art that battery replacement cannot be performed when communication between the vehicle and the battery replacement station is abnormal. To this end, one purpose of this application is to provide a battery replacement control method so that when communication between the vehicle and the battery replacement station is abnormal, the battery replacement process can be controlled normally based on a mobile terminal, thereby reducing the risk of battery replacement failure.

[0005] An embodiment of the first aspect of the present application provides a battery replacement control method, which is executed by a mobile terminal, including: when the communication connection between the battery swap station and the vehicle is disconnected, the mobile terminal establishes a communication connection with the vehicle; based on the communication connection between the mobile terminal and the vehicle, the mobile terminal obtains status information of the vehicle; the mobile terminal determines whether the vehicle meets the battery replacement conditions based on the status information; in response to the vehicle meeting the battery replacement conditions, the mobile terminal controls the vehicle to power off in order to replace the battery.

[0006] In the technical solution of the embodiments of this application, when communication between the vehicle and the battery swap station is abnormal, a mobile terminal can be used to establish a communication connection with the vehicle, enabling the mobile terminal to control the battery swap process. Once it is determined that the vehicle is capable of battery replacement, the mobile terminal controls the vehicle to power off, allowing subsequent battery swap operations to proceed, reducing the risk of battery swap failure.

[0007] In some embodiments, when the communication connection between the battery swap station and the vehicle is disconnected, the mobile terminal establishing a communication connection with the vehicle includes: when the communication connection between the battery swap station and the vehicle is disconnected, obtaining the communication address of the vehicle through the mobile terminal, wherein the communication address is determined based on at least one vehicle feature of the vehicle, and the at least one vehicle feature includes at least one of the license plate number, frame number, vehicle model, and owner information. Obtaining the communication address of the vehicle through the mobile terminal includes: obtaining at least one vehicle feature through the mobile terminal; based on the at least one vehicle feature, the mobile terminal obtains the communication address; based on the communication address, the mobile terminal establishes a communication connection with the vehicle. After obtaining the vehicle features, the mobile terminal can obtain the communication address corresponding to the vehicle based on the obtained vehicle features, so that a communication connection can be accurately established between the mobile terminal and the vehicle that needs to be battery swapped.

[0008] In some embodiments, the battery replacement control method further includes: before the mobile terminal establishes a communication connection with the vehicle: the mobile terminal receives first communication status information sent by the cloud platform corresponding to the vehicle or the battery swap station, and the first communication status information indicates the communication connection status between the battery swap station and the vehicle. Before the mobile terminal establishes a communication connection with the vehicle for controlling the power battery replacement, the communication connection status between the battery swap station and the vehicle can be determined by receiving the first communication status information. When it is determined that the communication connection between the battery swap station and the vehicle is disconnected, the mobile terminal can establish a communication connection with the vehicle and control the vehicle to perform battery replacement through the communication connection.

[0009] In some embodiments, the battery replacement condition includes at least one of a vehicle door status condition, a steering wheel status condition, a vehicle gear status condition, a parking brake system status condition, and a brake pedal status condition. Determining whether the vehicle's condition is suitable for battery replacement before replacing the power battery can reduce the risk of abnormal failures during the battery replacement process and improve the safety of the replacement process.

[0010] In some embodiments, the mobile terminal controls the vehicle to power off in response to the vehicle meeting battery replacement conditions, including: controlling the vehicle to initiate a high-voltage power-off process in response to the vehicle meeting the battery replacement conditions; and controlling the vehicle to initiate a low-voltage power-off process in response to the vehicle completing the high-voltage power-off process. Before replacing the power battery, controlling the vehicle to perform both the high-voltage and low-voltage power-off processes disconnects the vehicle's high-voltage and low-voltage power supplies, improving the safety of the battery replacement process.

[0011] In some embodiments, the battery replacement control method further includes: the mobile terminal transmitting a first power-on instruction to the vehicle in response to completion of the vehicle battery replacement, the first power-on instruction being used to instruct the vehicle to initiate a high-voltage power-on process. After the power battery is replaced, the mobile terminal controls the vehicle to initiate the high-voltage power-on process, so that the replaced power battery provides high-voltage power to the vehicle, thereby enabling normal vehicle operation.

[0012] An embodiment of the second aspect of the present application provides a battery replacement control device, including: a first module, used to establish a communication connection between a mobile terminal and a vehicle when the communication connection between the battery swap station and the vehicle is disconnected; a second module, used to obtain status information of the vehicle based on the communication connection between the mobile terminal and the vehicle; a third module, used to determine whether the vehicle meets the battery replacement conditions based on the status information; and a fourth module, used to control the vehicle to power off in response to the vehicle meeting the battery replacement conditions to replace the battery.

[0013] An embodiment of the third aspect of the present application provides a mobile terminal, comprising: at least one processor; at least one memory communicatively connected to the at least one processor, the at least one memory storing instructions, which, when executed individually or collectively by the at least one processor, enable the mobile terminal to execute the battery replacement control method described in the above embodiment.

[0014] An embodiment of the fourth aspect of the present application provides a computer-readable storage medium storing instructions, which, when executed individually or collectively by one or more processors of a mobile terminal, enable the mobile terminal to execute the battery replacement control method described in the above embodiment.

[0015] An embodiment of the fifth aspect of the present application provides a computer program product, comprising instructions, which, when executed individually or collectively by one or more processors of a mobile terminal, enable the mobile terminal to execute the battery replacement control method described in the above embodiments.

[0016] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0032] 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.

[0033] With the development of new energy technologies, higher requirements are being placed on electric vehicles, such as longer driving range and faster charging speeds. Consequently, battery swapping has emerged, allowing the power batteries of electric vehicles to be replaced at battery swap stations. Through communication between the electric vehicle and the battery swap station, the power battery on the electric vehicle can be removed and replaced with the battery stored at the swap station. However, if communication between the electric vehicle and the swap station fails, such as a software or hardware failure in the communication link, the battery swap process will not proceed normally due to the lack of communication, resulting in battery swap failure.

[0034] To ensure that the power battery can be replaced normally even if communication between the vehicle and the battery swap station is abnormal, the mobile terminal can establish a communication connection with the vehicle when the communication between the vehicle and the battery swap station is abnormal. If the vehicle meets the battery replacement conditions, the mobile terminal can control the vehicle to power off, so that the battery swap process can proceed normally.

[0035] Using such a battery replacement control method, a mobile terminal can be used to communicate with the vehicle and control the battery replacement process when there is an abnormality in the communication between the battery swap station and the vehicle, thereby reducing the impact of the abnormal communication between the vehicle and the battery swap station on the battery replacement process, allowing the vehicle to be powered off normally and complete the battery replacement.

[0036] The battery replacement control method disclosed in the embodiments of this application can be used, but is not limited to, in the process of replacing batteries used in electrical devices such as vehicles. The battery replacement control method disclosed in this application can be used to replace the power battery normally even when communication between the vehicle and the battery swap station is abnormal, thereby reducing the impact of abnormal communication between the vehicle and the battery swap station on the battery swap process.

[0037] The embodiment of the present application provides a battery replacement control method 100. The battery replacement control method 100 is executed by a mobile terminal. Figure 1 , the battery replacement control method 100 includes steps 110 to 140.

[0038] Step 110: When the communication connection between the battery swap station and the vehicle is disconnected, the mobile terminal establishes a communication connection with the vehicle.

[0039] Step 120: Based on the communication connection between the mobile terminal and the vehicle, the mobile terminal obtains status information of the vehicle.

[0040] Step 130: The mobile terminal determines whether the vehicle meets the battery replacement conditions based on the status information.

[0041] In step 140 , in response to the vehicle meeting the battery replacement conditions, the mobile terminal controls the vehicle to power off in order to replace the battery.

[0042] In the embodiments of the present application, the term "battery" may include a battery cell, or a series, parallel, or hybrid structure of multiple battery cells (for example, a battery pack or a battery module). During the process of replacing the battery of an electric vehicle, after the electric vehicle enters a battery swap station, if the communication between the battery swap station and the electric vehicle is abnormal, the mobile terminal can establish a communication connection with the electric vehicle. Step 110 can be performed on the user's mobile terminal (for example, a smartphone, tablet computer, personal computer, etc.). At this time, the user's mobile terminal can communicate with the electric vehicle and control the battery swap process.

[0043] After establishing a communication connection with the electric vehicle, the mobile terminal can obtain the status information of the electric vehicle through the communication connection. The status information of the electric vehicle may include the status of the vehicle and the battery in the vehicle, such as the remaining battery power, the battery output voltage, whether the door is closed, whether the vehicle gear is in neutral, etc. Based on this status information, the mobile terminal can determine whether the electric vehicle meets the battery replacement conditions. When the electric vehicle meets the battery replacement conditions, the battery can be replaced. In step 140, the mobile terminal can control the electric vehicle to power off through the communication connection with the electric vehicle, that is, disconnect the power supply connection between the power battery and the electric vehicle, and then start replacing the power battery.

[0044] If communication between the vehicle and the battery swap station fails, a mobile terminal can be used to establish a communication connection with the vehicle, enabling the mobile terminal to control the battery swap process. Once the vehicle is confirmed to be capable of battery replacement, the mobile terminal controls the vehicle to power off, allowing subsequent battery swap operations to proceed, reducing the risk of battery swap failure.

[0045] According to some embodiments of the present application, reference Figure 2 , step 110 includes steps 210 to 220.

[0046] In step 210, when the communication connection between the battery swap station and the vehicle is disconnected, the vehicle's communication address is obtained via the mobile terminal. The communication address is determined based on at least one vehicle characteristic. The at least one vehicle characteristic includes at least one of the license plate number, vehicle frame number, vehicle model, and vehicle owner information.

[0047] Step 220: Based on the communication address, the mobile terminal establishes a communication connection with the vehicle.

[0048] refer to Figure 3 , step 210 includes steps 310 to 320.

[0049] Step 310: Acquire at least one vehicle feature through a mobile terminal.

[0050] Step 320: Based on at least one vehicle feature, the mobile terminal obtains a communication address.

[0051] In some embodiments, the vehicle's communication address may be the electric vehicle's Bluetooth address, such as a Bluetooth Media Access Control (MAC) address. Based on this Bluetooth MAC address, the mobile terminal can maintain a Bluetooth connection with the electric vehicle to control the battery replacement process. In some embodiments, the vehicle's communication address may be obtained from a cloud platform corresponding to the battery swap station where the vehicle is located. Vehicle information related to different electric vehicles can be uploaded and stored on the cloud platform. The cloud platform can identify the electric vehicle's communication address based on certain vehicle characteristics. For example, using the license plate number as a vehicle characteristic, the cloud platform identifies the vehicle's communication address based on the vehicle's license plate number. When the electric vehicle enters the battery swap station, the user uses a mobile terminal to capture the license plate number and uploads it to the cloud platform (for example, an application can be used to upload the license plate number to the cloud platform). The cloud platform identifies the corresponding electric vehicle's communication address based on the uploaded license plate number and sends it to the mobile terminal. In some embodiments, the cloud platform may also store the corresponding relationship between vehicles and users, such as the corresponding relationship between vehicles and mobile terminals under the same user name. When issuing the communication address, the cloud platform can verify the mobile terminal, and only send the vehicle's communication address to it when it is determined that the mobile terminal is the mobile terminal corresponding to the vehicle, thereby improving security. In other embodiments, the vehicle's communication address may also come from the vehicle and be sent by the vehicle to the mobile terminal. In this case, the mobile terminal and the vehicle may also belong to the same user and have a corresponding binding relationship. For example, the mobile terminal may have a binding relationship with the vehicle's license plate number and / or frame number. When the vehicle communicates abnormally with the battery swap station, the vehicle will send the communication address to the mobile terminal. When there are multiple mobile terminals bound to the vehicle, the vehicle can send the communication address to the mobile terminal based on which mobile terminal obtained the vehicle's characteristics.

[0052] In some embodiments, the mobile terminal may also obtain the communication address of the vehicle based on other vehicle characteristics of the electric vehicle, such as the vehicle model and owner information of the electric vehicle, etc., which is not limited in this disclosure.

[0053] After receiving the communication address of the vehicle, the mobile terminal can establish a communication connection with the electric vehicle.

[0054] After obtaining the vehicle characteristics, the mobile terminal can obtain the communication address corresponding to the vehicle based on the obtained vehicle characteristics, so that a communication connection can be accurately established between the mobile terminal and the vehicle that needs to be replaced.

[0055] According to some embodiments of the present application, the battery replacement control method 100 further includes, before step 110:

[0056] The mobile terminal receives first communication status information sent by a cloud platform corresponding to the vehicle or the battery swap station. The first communication status information indicates the communication connection status between the battery swap station and the vehicle.

[0057] The monitoring of the communication status between the battery swap station and the vehicle can be performed by the battery swap station and / or the vehicle. In some embodiments, the battery swap station can upload the communication connection status between the battery swap station and the vehicle to the cloud platform, and the cloud platform sends the communication status information to the mobile terminal. In other embodiments, if the mobile terminal and the vehicle are bound and in a bound state, or there is a physical connection between the mobile terminal and the vehicle, the vehicle can also send the first communication status information directly to the mobile terminal.

[0058] After receiving the first communication status information, the mobile terminal can determine whether the communication between the battery swap station and the vehicle is abnormal based on the first communication status information. When it is determined that the communication between the battery swap station and the vehicle is abnormal, the mobile terminal can establish a communication connection with the vehicle.

[0059] When it is determined that the communication connection between the battery swap station and the vehicle is disconnected, the mobile terminal can establish a communication connection with the vehicle and control the vehicle to perform battery swapping through the communication connection.

[0060] According to some embodiments of the present application, the battery replacement condition includes at least one of a vehicle door status condition, a steering wheel status condition, a vehicle gear status condition, a parking brake system status condition, and a brake pedal status condition.

[0061] The battery replacement conditions can be set according to different usage scenarios, and may include, for example, vehicle door status conditions (for example: "the vehicle door is closed"), steering wheel status conditions (for example: "the steering wheel is returned to the center position"), vehicle gear status conditions (for example: "the vehicle gear is in neutral"), parking brake system status conditions (for example: "the parking brake system is activated"), brake pedal status conditions (for example: "no external force is applied to the brake pedal"), etc.

[0062] Based on the status information of the electric vehicle obtained in step 120, it is determined whether the electric vehicle meets all battery replacement conditions. If all battery replacement conditions are met, the electric vehicle is deemed to be able to start the battery replacement process. If any of the battery replacement conditions are not met, the electric vehicle is deemed unable to start the battery replacement process. At this time, an abnormal prompt message can be generated to remind the user. The abnormal prompt message may include voice prompts, light prompts, text prompts, etc.

[0063] In some embodiments, different abnormal prompt messages can be generated for battery replacement conditions that are not met by the electric vehicle. For example, if the door of the electric vehicle is not closed, a voice prompt or text prompt "Please close the door" can be issued; if the steering wheel of the electric vehicle has not been returned to the center position, a voice prompt or text prompt "Please return the steering wheel to the center position" can be issued; if the gear position of the electric vehicle is not set to neutral, a voice prompt or text prompt "Please shift to neutral" can be issued; if the parking brake system of the electric vehicle is not activated, a voice prompt or text prompt "Please apply the handbrake" can be issued; if the user has not released the brake pedal, a voice prompt or text prompt "Please release the footbrake" can be issued, etc.

[0064] Before replacing the battery, first determine whether the electric vehicle's status meets all replacement conditions. If any replacement condition is not met, the battery will not be replaced, reducing the risk of abnormal failure during the battery replacement process and improving the safety of the battery replacement process.

[0065] According to some embodiments of the present application, the mobile terminal may provide a battery replacement control interface to the user of the electric vehicle so that the user can determine whether to replace the battery of the electric vehicle.

[0066] The battery replacement control interface may be provided with a confirmation button for indicating whether to replace the battery of the electric vehicle. When the user clicks the confirmation button, the battery of the electric vehicle begins to be replaced.

[0067] In some embodiments, the battery replacement control interface can be displayed by an application (Application, App for short) installed in the user's mobile terminal.

[0068] During the battery replacement process of an electric vehicle, users can determine the number and method of replacing batteries through the battery replacement control interface, expanding the use scenarios of the battery replacement process so that it can meet the needs of more users.

[0069] When the user performs a confirmation operation on the battery replacement control interface, such as clicking the confirmation button, the mobile terminal controls the vehicle to power off and then starts replacing the power battery.

[0070] In one example, a user's mobile terminal and an electric vehicle are connected in communication via a Bluetooth address. When the user decides to replace the battery of the electric vehicle, the mobile terminal sends a first power-off instruction (for example, a request for a high-voltage instruction HVPwrOffRuquest, etc.) to the electric vehicle via Bluetooth communication to control the vehicle to power off. After receiving the first power-off instruction, the electric vehicle transmits the first power-off instruction to the battery management unit (BMU) in the electric vehicle by transparent transmission (for example, transmitting it via a control area network (CAN) bus). The BMU forwards the first power-off instruction to the vehicle control unit (VCU). The VCU controls the electric vehicle to start the high-voltage power-off process, so that the electric vehicle is in a high-voltage power-off state, and the high-voltage electrical connection between the battery and the electric vehicle remains disconnected.

[0071] The battery can be replaced when the user determines that it needs to be replaced, enabling the user to independently control the battery replacement process, making the battery replacement process more in line with user needs.

[0072] According to some embodiments of the present application, the battery replacement control interface includes at least one battery replacement mode for the user to select a corresponding battery replacement mode.

[0073] The battery replacement control interface can display a variety of different battery replacement modes to the user. For example, if the battery used in the electric vehicle includes multiple battery packs, the battery replacement control interface may include battery replacement modes such as single battery pack replacement and multiple battery pack replacement, and may also include a battery replacement mode that allows users to select the number of battery packs to replace.

[0074] The battery replacement control interface may be provided with different selection buttons for different battery replacement modes, and the corresponding battery replacement mode may be selected based on the button clicked by the user; or a text box for user input may be provided, and the corresponding battery replacement mode may be selected based on the text entered by the user. The specific configuration of the battery replacement control interface is not limited in this disclosure.

[0075] When starting the battery replacement process, users can independently select the required battery replacement mode, thereby meeting more user needs.

[0076] After the user selects the corresponding battery replacement mode, the mobile terminal can control the vehicle to power off according to the battery replacement mode. According to the battery replacement mode selected by the user (for example, replacing different numbers of battery packs, replacing battery packs at a scheduled time, etc.), the mobile terminal controls the vehicle to start different power-off processes (for example, disconnecting the high-voltage electrical connection between the corresponding battery pack and the electric vehicle, starting the high-voltage power-off process at a scheduled time, etc.). In one example, the battery in the electric vehicle includes three battery packs. On the battery replacement control interface, the user can select different battery replacement modes such as single battery pack replacement, dual battery pack replacement, and triple battery pack replacement. If the user selects single battery pack replacement, the mobile terminal can control the electric vehicle to disconnect the electrical connection between one of the battery packs and the electric vehicle; if the user selects dual battery pack replacement, the mobile terminal can control the electric vehicle to disconnect the electrical connection between two of the battery packs and the electric vehicle; if the user selects triple battery pack replacement, the mobile terminal can control the electric vehicle to disconnect the electrical connection between the three battery packs and the electric vehicle.

[0077] After the user selects the required battery replacement mode, the mobile terminal controls the electric vehicle to start the corresponding power-off process according to the battery replacement mode selected by the user, so that the corresponding battery replacement process can be carried out according to the user's selection, thereby improving the freedom and flexibility of the battery replacement process.

[0078] According to some embodiments of the present application, reference Figure 4 , step 140 includes steps 410 to 420.

[0079] In step 410 , the mobile terminal controls the vehicle to start the high-voltage power-off process in response to the vehicle meeting the battery replacement conditions.

[0080] In step 420 , the mobile terminal controls the vehicle to start the low-voltage power-off process in response to the vehicle completing the high-voltage power-off process.

[0081] In the embodiments of this application, the term "high-voltage power-off" refers to the disconnection of the high-voltage electrical connection between the battery and the electric vehicle, resulting in the battery ceasing to supply high-voltage power to the electric vehicle. The term "low-voltage power-off" refers to the disconnection of the low-voltage electrical connection between the battery and the electric vehicle, resulting in the cessation of low-voltage power supply to low-voltage loads in the electric vehicle (e.g., lighting system, audio system, etc.). For example, this may include disconnecting the electrical connection between the battery and the vehicle's DC-DC converter, or disconnecting the electrical connection between the vehicle's DC-DC converters.

[0082] After the electric vehicle executes the high-voltage power-off process, the mobile terminal can continue to send a second power-off instruction to the electric vehicle through the communication connection with the electric vehicle, so that the electric vehicle is in a low-voltage power-off state, and then start replacing the battery.

[0083] Before replacing the power battery, the vehicle is controlled to perform high-voltage power-off processes and low-voltage power-off processes, thereby disconnecting the vehicle's high-voltage power supply and low-voltage power supply, improving the safety of the battery replacement process.

[0084] According to some embodiments of the present application, the battery replacement control method 100 further includes: the mobile terminal sending a first power-on instruction to the vehicle in response to the completion of the battery replacement of the vehicle. The first power-on instruction is used to instruct the vehicle to start a high-voltage power-on process.

[0085] In the embodiments of this application, the term "high-voltage power-on" refers to restoring the high-voltage electrical connection between the battery and the electric vehicle, so that the battery can begin providing high-voltage power to the electric vehicle. After the battery replacement is complete, the mobile terminal can send a first power-on instruction to the electric vehicle through a communication connection with the electric vehicle, thereby placing the electric vehicle in a high-voltage power-on state.

[0086] After the power battery is replaced, the mobile terminal controls the vehicle to start the high-voltage power-on process, so that the replaced power battery provides high-voltage power to the vehicle, realizing normal operation of the vehicle.

[0087] According to some embodiments of the present application, the battery replacement control method 100 further includes:

[0088] In response to receiving first vehicle status information from the electric vehicle, a clear instruction is sent to the electric vehicle. The first vehicle status information is used to indicate that the electric vehicle is in a normal state. The clear instruction is used to instruct the electric vehicle to clear status statistics generated during the battery replacement process.

[0089] During the battery swap process, statistics are collected on the relevant information generated during the swap process, including status information generated both inside and outside the swap station. After the battery swap is complete, the status statistics generated during the swap process need to be cleared to ensure the subsequent normal operation of the electric vehicle and to facilitate information statistics for the next battery swap process.

[0090] After the battery replacement is complete, the electric vehicle will perform a self-check of its status. If the vehicle status is determined to be normal, the electric vehicle will transmit first vehicle status information. Upon receiving this information, the mobile terminal can, through its communication connection with the electric vehicle, send a clear instruction to the electric vehicle. This clear instruction can be designed as needed, for example, including a "request to clear subtotal information" instruction. When the electric vehicle receives this clear instruction, it will clear the status statistics generated during the power battery replacement process.

[0091] After the battery replacement is completed, if the electric vehicle is in normal condition, the status statistics information of this battery replacement process will be cleared to reduce the impact of the status statistics information on the next battery replacement process.

[0092] According to some embodiments of the present application, the battery replacement control method 100 further includes: in response to receiving second vehicle status information from the electric vehicle, the mobile terminal disconnecting the communication connection with the electric vehicle. The second vehicle status information is used to indicate that the clearing of the status statistics information is complete.

[0093] After clearing the status statistics generated during the battery swap process, the electric vehicle may send a second vehicle status message to indicate the completion of the clearing. This clearing result instruction can be designed based on the detection requirements, for example, including a "subtotal information cleared completed" instruction. After receiving the second vehicle status message, the mobile terminal disconnects the communication connection with the electric vehicle, at which point the electric vehicle can exit the battery swap station.

[0094] When the status statistics information is cleared, the battery replacement process is considered to be completed. At this time, the communication connection between the mobile terminal and the electric vehicle can be disconnected, and the electric vehicle can perform subsequent operations normally.

[0095] According to some embodiments of the present application, the battery replacement control method 100 further includes: in response to receiving the second vehicle status information from the electric vehicle, the mobile terminal generates a battery replacement result signal. The battery replacement result signal is used to indicate that the battery replacement of the electric vehicle is completed.

[0096] In some embodiments, the battery replacement result information can be uploaded to the cloud platform to generate a battery replacement order. The battery replacement order will be sent by the cloud platform to the user's mobile terminal, and the user can pay the fees incurred during the battery replacement process in the corresponding app.

[0097] It should be noted that the order in which the mobile terminal disconnects the communication connection with the vehicle and generates the battery replacement result signal can be designed according to usage requirements, and this disclosure does not limit this.

[0098] After the battery replacement process is completed, a replacement result signal is generated to indicate that the battery replacement is complete and the electric vehicle can leave the battery replacement station.

[0099] Based on the same technical concept, the embodiment of the present application provides a battery replacement control device. The embodiment of the battery replacement control device can refer to the embodiment of the control method, and the repeated parts will not be repeated.

[0111] Memory 607 and mass storage device 606 are examples of computer-readable storage media for storing instructions that are executed by processor 605 to implement the various functions described above. For example, memory 607 may generally include both volatile memory and non-volatile memory (e.g., RAM, ROM, etc.). In addition, mass storage device 606 may generally include a hard drive, a solid-state drive, removable media, including external and removable drives, memory cards, flash memory, floppy disks, optical disks (e.g., CDs, DVDs), storage arrays, network attached storage, storage area networks, etc. Memory 607 and mass storage device 606 may be collectively referred to herein as memory or computer-readable storage media and may be non-transitory media capable of storing computer-readable, processor-executable program instructions as computer program code, which may be executed by processor 605 as a specific machine configured to implement the operations and functions described in the examples herein.

[0119] An embodiment of the present application further provides a computer program product, comprising instructions, which, when executed individually or collectively by one or more processors of a mobile terminal, enable the mobile terminal to execute the control method in any of the above embodiments.

[0120] 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.

[0121] If the communication connection between the battery swap station and the electric vehicle is disconnected and the user needs to replace the battery in the electric vehicle, they can use their mobile terminal to capture the electric vehicle's license plate number when the electric vehicle enters the battery swap station and upload it to the cloud platform corresponding to the battery swap station. The cloud platform identifies the electric vehicle's communication address (for example, Bluetooth MAC address) based on the captured license plate number and sends the electric vehicle's communication address to the user's mobile terminal. Based on this communication address, the user's mobile terminal can establish a communication connection with the electric vehicle. After the communication connection is established, the mobile terminal can obtain status information sent by the electric vehicle.

[0122] After the electric vehicle stops at the corresponding battery swap station, the system determines whether the electric vehicle meets the battery replacement conditions based on the acquired electric vehicle status information. The battery replacement conditions include at least one of the following: vehicle door status, steering wheel status, vehicle gear status, parking brake system status, and brake pedal status. Each of these battery replacement conditions is verified sequentially. First, the system determines whether the electric vehicle's doors are closed. If not, a voice or text prompt "Please close the doors" is issued. If the doors are closed, the system determines whether the steering wheel has returned to the center position. If not, a voice or text prompt "Please return the steering wheel" is issued. If the steering wheel has returned to the center position, the system determines whether the electric vehicle's gear is in neutral. If not, a voice or text prompt "Please shift to neutral" is issued. If the gear is in neutral, the system determines whether the parking brake system is engaged. If not, a voice or text prompt "Please apply the parking brake" is issued. If the parking brake system is activated, determine whether external force is applied to the brake pedal. If the user has not released the brake pedal, issue a voice prompt or text prompt such as "Please release the foot brake". If the user has released the brake pedal, the mobile terminal provides the user with a battery replacement control interface. On the battery replacement control interface, the user can select different battery replacement modes and whether to replace the battery. After the user determines the battery replacement mode and determines to replace the battery, the mobile terminal controls the electric vehicle to power off according to the battery replacement mode selected by the user. The mobile terminal first controls the electric vehicle to start the high-voltage power-off process. After the electric vehicle completes the high-voltage power-off process, it controls it to start the low-voltage power-off process. After the electric vehicle completes the low-voltage power-off process, the battery can be replaced.

[0123] After the battery replacement is completed, the mobile terminal sends a first power-on instruction to the electric vehicle. The electric vehicle starts the high-voltage power-on process according to the first power-on instruction. After completing the high-voltage power-on process, the electric vehicle performs a self-check on the status of the vehicle. When it is determined that the vehicle status is normal, the electric vehicle will send the first vehicle status information. After receiving the first vehicle status information, the mobile terminal sends a clear instruction to the electric vehicle. The electric vehicle clears the status statistics generated during the battery replacement process according to the clear instruction. After clearing the status statistics, the electric vehicle sends a second vehicle status information to indicate that the clearing is complete. After receiving the second vehicle status information, the mobile terminal can disconnect the communication connection with the electric vehicle and drive away from the battery swap station. In addition, after receiving the second vehicle status information, the mobile terminal can also generate a battery replacement result signal and upload it to the cloud platform. The cloud platform generates a battery replacement order based on the battery replacement result signal, and the user can pay the corresponding fee for the battery replacement order in the corresponding App on the mobile terminal.
