[0044] In order to make the purpose, technical solutions and advantages of this application more clear, the following is a further detailed description of this application in combination with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments described in the embodiments of this application are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0045] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "include" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0046] In order to make the following embodiments clear, the technical terms involved in the embodiments of the present application are first introduced:

[0047] TBOX (Telematics Box): TBOX is an electronic device installed in the vehicle to enable communication between the vehicle and external systems. It usually supports GPS positioning, mobile communications (such as 4G / 5G), remote diagnosis, vehicle monitoring and other functions. TBOX can communicate with other modules of the vehicle (such as BMS) to collect and transmit vehicle data.

[0048] VSU (Vehicle Status Unit): VSU is responsible for monitoring and recording various status information of the vehicle, such as speed, fuel consumption, battery status, etc., and sending this information to other modules or systems. It is usually used in conjunction with TBOX to provide real-time status data of the vehicle.

[0049] TSP (Telematics Service Provider): TSP is a company or organization that provides telematics services. It is responsible for processing, storing and analyzing vehicle data and providing users with various value-added services such as navigation, remote diagnosis, vehicle monitoring, etc. TSP usually interacts with vehicles through TBOX.

[0050] BMS (Battery Management System): BMS is a system used to manage and monitor battery packs. Its main functions include battery status monitoring (such as voltage, current, temperature, etc.), charging control, discharge protection, battery balancing, etc. In electric vehicles, BMS is a key component to ensure battery safety and extend battery life.

[0051] CAN (Controller Area Network): CAN is a serial communication protocol widely used in automotive and industrial control systems. It allows multiple electronic control units (ECUs) to communicate data efficiently and reliably in a network. The CAN bus has the advantages of high reliability, good real-time performance, and low cost. It is a standard communication protocol commonly used in automotive electronic systems.

[0052] As described above, the remote control function for vehicle batteries can support vehicle owners to manage the status of vehicle batteries in real time. In the current remote control method for vehicle batteries, remote control of vehicle batteries can only be achieved through a single remote locking and unlocking method. This remote control method is relatively simple and cannot adapt to complex vehicle application scenarios. The remote control effect of vehicle batteries is poor.

[0053] In order to solve the above problems, the embodiments of the present application provide a vehicle battery remote control system, method, electronic device and medium, in which the system includes a TBOX module, a TSP platform, a BMS module and a VCU module. Among them, the TSP platform serves as an intermediate platform for the user end to transmit control instructions, and transmits the remote control instructions for the vehicle battery from each user end to the corresponding TBOX module, thereby providing a unified export of standardized commands for the control instructions, and ensuring the remote control efficiency for the vehicle battery. On the other hand, the VCU module will periodically send the vehicle's driving status data and the vehicle's battery status data to the TBOX module and the BMS module respectively, so that the TBOX module and the BMS module can execute the vehicle battery remote control instructions according to the actual situation of the vehicle.

[0054] Specifically, when the TBOX module receives the vehicle battery remote control command from the TSP platform, the TBOX module first makes a preliminary judgment on whether to control or not based on the driving status data of the vehicle. When it is determined that the vehicle battery can be remotely controlled, the TBOX module can send the remote control command to the BMS module, because the BMS module executes the specific control command. Correspondingly, the BMS module needs to further determine whether the current battery state of the vehicle matches the preset remote control rules based on the command type of the received vehicle battery remote control command and the battery status data of the vehicle fed back by the VCU module, and then support the execution of the remote control command. When the two match, the BMS module executes the vehicle battery remote control command to achieve remote control of the vehicle battery. In this way, through the combined use of the BMS module and the TBOX module, the vehicle's driving status and battery status are used as references for the remote control of the vehicle battery, so that the actual control process can be more in line with the complex application scenarios of the vehicle, thereby effectively solving the problem that the current remote control method for the vehicle battery is relatively single, and improving the remote control effect of the vehicle battery.

[0055] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] Next, the vehicle battery remote control system provided by the embodiment of the present application will be introduced in conjunction with the specific embodiment drawings. Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a vehicle battery remote control system provided in an embodiment of the present application, Figure 2 The signaling interaction diagram between the modules in the remote control system of the embodiment of the present application is shown in the figure. In the scenario of remote control of the vehicle battery, the user can remotely control the vehicle battery through the authorized network platform or applet, which uses the TSP platform as a unified export for various vehicle battery control instructions, so as to centrally manage and monitor all control instructions and corresponding battery status logs through the TSP platform, so as to achieve stricter safety control, thereby greatly improving the safety of remote control of vehicle batteries.

[0057] like Figure 1 As shown, in the vehicle battery remote control system provided in the embodiment of the present application, it specifically includes a TBOX module 100, a BMS module 200, a VCU module 300, a TSP platform 400 and a user terminal 500. Among them, the VCU module serves as a vehicle body control unit, which sends the collected vehicle driving status data and vehicle battery status data to the TBOX module and the BMS module respectively, so that the TBOX module and the BMS module can remotely control the vehicle battery according to the actual received status data.

[0058] The TBOX module 100 is used to determine whether the vehicle battery can be remotely controlled according to the vehicle driving status data, and when it is determined that the vehicle battery can be remotely controlled, send the vehicle battery remote control instruction to the BMS module.

[0059] The TBOX module is used to receive the vehicle driving status data periodically transmitted by the VCU module, as well as the vehicle battery remote control instructions from the TSP platform. When the TBOX module receives the vehicle battery remote control instruction, if the vehicle is in driving state at this time, then the current battery remote control may have a certain impact on driving safety. Therefore, in order to ensure the driving safety of the vehicle, when the TBOX module receives the vehicle battery remote control instruction, the TBOX module needs to determine the current driving state of the vehicle based on the vehicle driving status data periodically transmitted by the VSU module, and use this to determine whether the vehicle can be remotely controlled at present. Only when it is confirmed that the vehicle can be remotely controlled at present, the TBOX module will send the vehicle battery remote control instruction to the BMS module, so that the BMS module can execute the corresponding vehicle battery remote control instruction.

[0060] In the embodiment of the present application, the TBOX module communicates with the TSP platform through the communication protocol HTTP / HTTPS, and the data packet encapsulation between the two can adopt the 32960 protocol. The TBOX module sends the message containing the vehicle battery remote control instruction to the BMS module through the CAN communication bus. In addition, in the actual application scenario, the TSP platform needs to have a command issuing interface, a issuing record query interface, and a development interface to receive commands sent by other platforms, so as to support the user end to remotely control the vehicle battery and real-time query of the battery status.

[0061] For details, please refer to Figure 3 The flow chart of a TBOX module judging whether the battery of the vehicle can be remotely controlled is shown in the figure. As can be seen from the figure, when the vehicle is currently in driving state, the TBOX module does not execute the vehicle battery remote control command, and temporarily stores the vehicle battery remote control command in the module, while monitoring the vehicle driving state data periodically transmitted by the VSU module in real time. Only when the vehicle driving state data transmitted by the VSU module changes from the original driving state to the non-driving state, the TBOX module can allow the execution of the vehicle battery remote control command, and send the vehicle battery remote control command to the BMS module, and the BMS module will execute the specific control steps.

[0062] Correspondingly, if the current driving state of the vehicle itself is a non-driving state, it means that the BMS can execute specific battery control instructions, and the TBOX module can directly send the vehicle battery remote control instructions to the BMS module.

[0063] In one possible implementation, in order to prevent potential network risks, when the TBOX module receives a vehicle battery remote control command, it can also identify the control authority of the user end through the user authority identification unit built into the TBOX module. When it is identified that the user end does not have the remote control authority of the vehicle, the vehicle battery remote control command is intercepted to ensure the network security of the vehicle.

[0064] Specifically, the user authority identification unit can be found in Figure 4 The flowchart of a user authority identification shown in FIG. 1 specifically includes the following steps:

[0065] S101: Determine the identity of the user terminal according to the vehicle battery remote control instruction;

[0066] S102: Matching the identity of the user terminal with a preset whitelist set to determine the remote control authority of the user terminal over the vehicle.

[0067] First, when the TBOX module receives the vehicle battery remote control command, the user authority identification unit obtains the identity of the user terminal contained in the vehicle battery remote control command, and matches and filters its identity with the pre-set identity in the preset whitelist, so as to realize the identity identification of the user terminal and obtain the user terminal's remote control authority for the vehicle.

[0068] The identity identifier of the user terminal may be an IP address, a port name, etc. of the user terminal, which is not specifically limited in this embodiment.

[0069] S103: When the remote control authority is none, the TBOX module is prohibited from sending the vehicle battery remote control instruction to the BMS module, and the remote control authority information is fed back to the user end through the TSP platform.

[0070] S104: When the remote control authority is yes, send the remote control authority information and the vehicle battery remote control instruction to the BMS module.

[0071] Correspondingly, when the user has remote control authority, the information that the user has remote control authority and the control command are sent to the BMS module. After receiving the information that the user has remote control authority, the BMS module can execute the specific control command. In this way, through the screening and matching between the preset whitelist set and the user's identity, the identity authority identification for the user can be effectively realized, so that the control command without remote control authority can be intercepted, thereby ensuring the network security of the vehicle.

[0072] The BMS module 200 is used to determine whether the vehicle battery status data matches the preset remote control rules based on the instruction type of the vehicle battery remote control instruction and the vehicle battery status data, and to remotely control the vehicle battery through the vehicle battery remote control instruction when the vehicle battery status data matches the preset remote control rules.

[0073] After the TBOX module makes a preliminary judgment on the vehicle battery remote control command, the BMS module implements the specific control logic of the control command. When the BMS module executes the vehicle battery remote control command, if the vehicle battery status is not sufficient to support the corresponding control command, the lack of direct control over the battery status judgment will cause damage to the battery. Therefore, in order to prevent such situations and improve the remote control effect of the vehicle battery, when the BMS module executes the remote control command, based on its reference command type, the BMS also needs to determine whether the vehicle battery status data matches the preset remote control rules, so as to determine whether the vehicle battery remote control command can be executed at present.

[0074] The preset remote control rules are related to the command type of the vehicle battery remote control command, and different command types correspond to different preset remote control rules. When the vehicle battery status data does not match the preset control rules, it indicates that the current battery status cannot support the execution of the command, thereby ensuring the safety of battery use.

[0075] Next, the process of the BMS module executing the vehicle battery remote control command will be introduced in conjunction with the specific embodiment drawings.

[0076] See also Figure 5 , which is a schematic diagram of a flow chart of a BSM module executing a vehicle battery remote control instruction provided by an embodiment of the present application, specifically comprising the following steps:

[0077] S201: Determine whether the vehicle battery remote control instruction is a charge restriction instruction or a discharge restriction instruction;

[0078] S2011: when the vehicle battery remote control instruction is a charging restriction instruction, extracting the battery SOC value and the total charge capacity from the battery status data of the vehicle;

[0079] S2022: When at least one of the battery SOC value and the total charge capacity is greater than the preset charging threshold value corresponding to each of them, the charging power of the battery of the vehicle is limited through a charging limit instruction so that the charging power is not higher than the preset first threshold value.

[0080] In the vehicle battery remote control system of the embodiment of the present application, the remote control instructions for the vehicle battery are divided into charging limit instructions and discharging limit instructions. Among them, the charging limit instruction is used to limit the charging power of the vehicle battery, and the discharging limit instruction is used to limit the discharging power of the vehicle battery. As can be seen from the foregoing, in order to ensure that the battery is not damaged, before executing the vehicle battery control instruction, it is necessary to determine whether the state of the vehicle battery can support the execution of the instruction. Therefore, in the specific execution stage of the instruction, different judgment processes are provided for different instruction types such as charging limit instructions and discharging limit instructions, so that different judgment processes can be adopted according to different instruction types, thereby ensuring that the battery is not damaged.

[0081] Specifically, when the vehicle battery remote control instruction is a charging restriction instruction, it is necessary to extract the battery SOC value of the vehicle battery and the total charge of the vehicle battery from the battery status data of the vehicle. When any of the battery SOC value and the total charge is greater than the preset charging threshold value corresponding to each of them, it indicates that the charging condition of the vehicle exceeds expectations. At this time, the charging power indicated in the charging restriction instruction can be limited so that the charging power of the vehicle battery is not higher than the preset first threshold value, thereby realizing the charging restriction of the vehicle battery.

[0082] In this way, by limiting the battery SOC value, when the battery SOC value reaches a certain level, the charging power can be limited to avoid overcharging the battery. Furthermore, by limiting the total charge amount, the battery can be prevented from accumulating too much heat when charged at high power for a long time, further protecting the health and life of the battery.

[0083] S2013: when the vehicle battery remote control instruction is a discharge limit instruction, extract the battery SOC value and the operation log of the BMS module from the battery status data of the vehicle;

[0084] S2014: If the battery SOC value is greater than the preset second threshold value and there is no power limit fault log in the operation log, the discharge power of the vehicle battery is limited based on the discharge limit instruction so that the discharge power is not higher than the preset third threshold value.

[0085] Correspondingly, when the vehicle battery remote control instruction is a discharge limit instruction, it is necessary to extract the battery SOC value and the operation log of the BMS module from the battery status data of the vehicle. If the battery SOC value is greater than the preset second threshold, and there is no fault log related to the power limit function in the operation log of the BMS module. At this time, the discharge power of the vehicle battery can be limited based on the discharge limit power specifically indicated in the discharge limit instruction to set the discharge power of the vehicle battery below the preset third threshold.

[0086] In this way, the discharge is limited when the SOC of the vehicle battery is greater than the preset second threshold value, which can ensure that the battery is protected at a higher state of charge. The battery may experience performance degradation or even damage at a low state of charge. By limiting the discharge power, the battery can be prevented from over-discharging at high SOC values, thereby extending the battery life. Accordingly, the discharge power is limited while ensuring that there is no power limit fault log in the operation log, ensuring that the battery management system operates normally and that there are no faults that may cause battery damage. This can prevent unnecessary protection of the battery under abnormal circumstances, which may affect the normal use of the vehicle.

[0087] In a possible implementation, a status feedback unit is also provided in the BMS module, and the status feedback unit is used to transmit the execution status of the vehicle battery remote control instruction and the battery status data of the vehicle battery back to the TBOX module through the CAN communication network, so that the TBOX module transmits the battery status data after the control instruction is executed to the user end, so that the user end can check the battery status of the vehicle battery in time after the instruction is executed, thereby optimizing the user experience of remote control of the vehicle battery.

[0088] It should be noted that in the vehicle battery remote control system of the embodiment of the present application, the communication between the modules is completed based on the CAN communication matrix composed of the CAN communication networks between each other. In the communication matrix of the embodiment of the present application, it is required that the CAN communication must contain the relevant protocols of the following information. That is, the message information (charging limit, discharging limit, control authority and shutdown) that the TBOX module can send to the BMS module, and the battery status data, control authority information, etc. that the BMS module can feedback through the CAN communication network.

[0089] In another possible implementation, a monitoring unit is also provided in the BMS module. As can be seen from the foregoing, when the TBOX module user terminal has the remote control authority for the vehicle, it will send information that the user terminal has the remote control authority to the BMS module, so as to use it as the basis for the BMS to execute the remote control command. Therefore, when the BMS module receives the remote control authority information fed back by the TBOX module, it can monitor the heartbeat signal from the TBOX module in real time to ensure that the BMS module always remains online and operates normally.

[0090] The monitoring unit will pre-set a preset time. When it receives the remote control authority information fed back by the TBOX module, it will monitor the heartbeat signal of the TBOX module based on the preset time. If the BMS module fails to receive the heartbeat signal of the TBOX module within the preset time, the BMS module will automatically limit the discharge of the vehicle battery. The specific measures for the discharge limit processing include limiting the discharge power of the battery so that it is not higher than the preset threshold. This can prevent the battery from being over-discharged in the event of failure of the TBOX module or communication interruption, thereby protecting the safety and life of the battery.

[0091] The embodiment of the present application provides a vehicle battery remote control system, in which the system includes a TBOX module, a TSP platform, a BMS module and a VCU module. Among them, the TSP platform serves as an intermediate platform for the user end to transmit control instructions, and transmits the remote control instructions for the vehicle battery from each user end to the corresponding TBOX module, thereby providing a unified export of standardized commands for the control instructions, and ensuring the remote control efficiency for the vehicle battery. On the other hand, the VCU module will periodically send the vehicle driving status data and the vehicle battery status data to the TBOX module and the BMS module respectively, so that the TBOX module and the BMS module can execute the vehicle battery remote control instructions according to the actual situation of the vehicle.

[0092] Specifically, when the TBOX module receives the vehicle battery remote control command from the TSP platform, the TBOX module first makes a preliminary judgment on whether to control or not based on the driving status data of the vehicle. When it is determined that the vehicle battery can be remotely controlled, the TBOX module can send the remote control command to the BMS module, because the BMS module executes the specific control command. Correspondingly, the BMS module needs to further determine whether the current battery state of the vehicle matches the preset remote control rules based on the command type of the received vehicle battery remote control command and the battery status data of the vehicle fed back by the VCU module, and then support the execution of the remote control command. When the two match, the BMS module executes the vehicle battery remote control command to achieve remote control of the vehicle battery. In this way, through the combined use of the BMS module and the TBOX module, the vehicle's driving status and battery status are used as references for the remote control of the vehicle battery, so that the actual control process can be more in line with the complex application scenarios of the vehicle, thereby effectively solving the problem that the current remote control method for the vehicle battery is relatively single, and improving the remote control effect of the vehicle battery.

[0093] A vehicle battery remote control method provided in an embodiment of the present application is introduced below. The vehicle battery remote control method described below and the vehicle battery remote control method described above can refer to each other.
