[0037] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0038] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0039] The terms used in the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a", "said" and "the" used in the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0040] It should be understood that although the terms first, second, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, a first parameter may also be referred to as a second parameter, and similarly, a second parameter may also be referred to as a first parameter. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0041] Due to the differences between the international charging protocol and the national standard charging protocol and the special needs of vehicle manufacturers, a communication protocol converter EVCC is required for protocol conversion. Specifically, when the vehicle has a communication protocol converter EVCC, the communication protocol converter EVCC and the AC charging pile usually confirm the charging guidance during AC charging; when there is no communication protocol converter EVCC, the on-board charger and the AC charging pile usually confirm the charging guidance. In other words, the on-board charger implements different strategies depending on whether there is a communication protocol conversion module or not.

[0042] Currently, compatible communication protocol conversion modules on the market are usually implemented using the following two solutions.

[0043] The first method is to implement it through CAN signals, and determine whether the vehicle has a communication protocol conversion module by whether the communication protocol conversion module signal is received through the CAN network; the disadvantage of this method is that when the communication protocol conversion module signal is lost, the on-board charger cannot distinguish whether the communication protocol conversion module has a signal loss failure or is configured as the communication protocol conversion module does not exist.

[0044] The second method is to use the diagnostic identifier (DID) of the Unified Diagnostic Services (UDS) to implement it. The vehicle writes the UDSDID to the on-board charger when it is offline. The on-board charger implements different software through different DID information. This solution often requires diagnostic equipment to develop dedicated DID writing. If it involves the configuration of multiple controllers, it will increase the offline time of the production line, and the update and maintenance of the configuration information may require special diagnostic equipment or specific operating procedures, which will bring certain difficulties to the maintenance of the vehicle configuration information. If the on-board charger needs to adapt to more types of charging protocols or software requirements, the current method may not be able to fully meet all situations and needs further improvement.

[0045] In view of the problems in the above-mentioned related technologies, the solution shown in the following embodiments of this application can be adopted to solve how to achieve compatibility with national and European standard charging protocols in the on-board charger, so that the same on-board charger assembly can perform different software requirements in different situations. The solution shown in the following embodiments of this application can effectively manage and transmit configuration information, ensure the accuracy and stability of configuration information, and achieve flexibility and reliability in compatibility with different charging protocols.

[0046] Please refer to Figure 1 , which shows a schematic diagram of an implementation environment of a configuration information processing method provided by an exemplary embodiment of the present application. Figure 1 As shown, the implementation environment may include: a vehicle 110 and a diagnostic device 120 .

[0047] The vehicle 110 includes a vehicle control system 110 a , which may be connected to a diagnostic device 120 .

[0048] The above-mentioned vehicle control system 110a may include but is not limited to one or more of the following: a vehicle-mounted telematics box (TBOX), a vehicle dispatch monitoring terminal (TCU), a vehicle-mounted navigation system, a vehicle-mounted video monitoring system, a driving recorder, and an intelligent central console / vehicle computer. Among them, the vehicle-mounted TBOX provides remote communication capabilities, supports functions such as vehicle remote control, data upload to the cloud, remote diagnosis, and software over-the-air technology (OTA); TCU is used for vehicle monitoring and dispatch management, integrating satellite positioning, data communication, and vehicle status monitoring functions; the vehicle-mounted navigation system is used to provide map navigation services, and can plan driving routes for vehicles in combination with traffic information; the vehicle-mounted video monitoring system includes a vehicle-mounted video server, a camera, etc., for video monitoring inside and outside the vehicle, supporting video recording, remote viewing and downloading; the driving recorder is used to record video images and sounds during vehicle driving; the intelligent central console / vehicle computer integrates a touch screen device with functions such as infotainment, navigation, vehicle settings, and mobile phone interconnection (such as Apple CarPlay, AndroidAuto), etc.

[0049] The vehicle control system 110a may include a plurality of functional modules connected via a CAN network, and the plurality of functional modules may include a configuration module and an on-board charger functional module.

[0050] For example, in Figure 1 In the system shown, the vehicle control system 110a can receive the vehicle configuration information written by the diagnostic device 120 through the configuration module of the vehicle control system; the vehicle configuration information includes charging protocol conversion configuration information and charging configuration information, the charging protocol conversion configuration information is used to indicate whether the vehicle contains a communication conversion unit, the communication conversion unit is used to convert communication signals of different charging protocols, and the charging configuration information is used to indicate the configuration information involved in the vehicle charging; the vehicle control system includes a plurality of functional modules connected through a CAN network; thereafter, through the configuration module, the vehicle control system 110a can send the charging protocol conversion configuration information and the charging configuration information to the on-board charger function module of the vehicle control system; thereafter, through the on-board charger function module, the vehicle control system 110a can write the charging protocol conversion configuration information into the electrically erasable programmable read-only memory EEPROM in the on-board charger function module; when the vehicle is charging, the vehicle control system 110a can read the charging protocol conversion configuration information and the charging configuration information through the on-board charger function module, and communicate with the charging pile according to the charging protocol conversion configuration information and the charging configuration information.

[0051] Please refer to Figure 2, which is a flowchart of a configuration information processing method provided by an embodiment of the present application. The method is applied to a new energy vehicle including a power battery, and the method can be executed by a vehicle control system. Optionally, the vehicle control system can be Figure 1 The vehicle control system 110a in the system shown. Figure 2 As shown, the method may include step 210 , step 220 , step 230 and step 240 .

[0052] Step 210: Receive vehicle configuration information written by the diagnostic device through the configuration module of the vehicle control system; the vehicle configuration information includes charging protocol conversion configuration information and charging configuration information, the charging protocol conversion configuration information is used to indicate whether the vehicle contains a communication conversion unit, the communication conversion unit is used to convert communication signals of different charging protocols, and the charging configuration information is used to indicate configuration information of different charging protocols involved in vehicle charging; the vehicle control system includes multiple functional modules connected through a CAN network.

[0053] In the embodiment of the present application, the vehicle control system includes multiple functional modules, which communicate with each other through the CAN network, and the multiple functional modules work together to ensure the normal operation and safety of the vehicle. Among them, the controller area network (CAN) is a common vehicle internal communication network used to connect various electronic control units (ECU) inside the vehicle, such as the engine control unit, the brake system control unit, the air conditioning control unit, etc. The CAN network has a fast transmission speed and high reliability, and is used to transmit real-time data and commands inside the vehicle.

[0054] Among them, the configuration module of the above-mentioned vehicle control system is one of the above-mentioned multiple functional modules and is also the management center of the configuration information. Exemplarily, the developer can designate a main functional module among multiple functional modules as the management center of the configuration information. The main controller is responsible for coordinating and distributing the configuration information of the entire vehicle and has higher authority and processing capabilities. For example, the configuration module of the above-mentioned vehicle control system can be a power system controller, a body control module, a dedicated gateway module, etc.

[0055] The diagnostic device may be a vehicle diagnostic instrument. The diagnostic device may be connected to the configuration module via a diagnostic port and write the vehicle configuration information into the configuration module. Exemplarily, the diagnostic port may be a vehicle standard on-board diagnostics (OBD) interface; the vehicle configuration information may also include vehicle model, optional accessories information, software version, etc.

[0056] Exemplarily, the above charging protocol conversion configuration information can be represented by 0 and 1. 0 represents that the vehicle does not include a communication conversion unit, and 1 represents that the vehicle includes a communication conversion unit.

[0057] The above charging configuration information refers to various configuration information involved in the vehicle's onboard charger function module when supporting different charging protocols. Exemplarily, the charging configuration information may include configuration information corresponding to two or more of the following different charging protocols: national standard, European standard, American standard, Japanese standard, etc.

[0058] Exemplarily, the communication conversion unit may be a communication protocol converter EVCC. The communication protocol converter (Electric Vehicle Communication Controller, EVCC) is a module in the electric vehicle charging system, which is used to convert communication protocols between different charging standards to ensure that electric vehicles can be charged at different types of charging stations.

[0059] In a possible implementation, before the vehicle is completed and about to roll off the production line, the above-mentioned diagnostic device can be connected to the above-mentioned configuration module through the diagnostic port, and then the above-mentioned configuration module receives the vehicle configuration information written by the diagnostic device. In other words, in the software configuration process before the vehicle is completed and about to roll off the production line, the present application can carry the charging protocol conversion configuration information and the charging configuration information in the vehicle configuration information, without the need to develop new diagnostic equipment, and realize the configuration of the charging protocol conversion configuration information and the charging configuration information without affecting the production line time.

[0060] Step 220: Send the charging protocol conversion configuration information and the charging configuration information to the on-board charger function module of the vehicle control system through the configuration module.

[0061] It should be noted that the configuration module can send the vehicle configuration information corresponding to each functional module to the corresponding functional module through the CAN network. In the embodiment of the present application, the vehicle configuration information corresponding to the on-board charger functional module includes charging protocol conversion configuration information and charging configuration information.

[0062] Among them, the above-mentioned on-board charger function module can be an on-board charger OBC. The on-board charger (OBC) is a key component in electric vehicles. The main function of the on-board charger is to convert alternating current (AC) into direct current (DC), and then transmit the power to the vehicle's power battery for charging.

[0063] Step 230: The charging protocol conversion configuration information is written into the electrically erasable programmable read-only memory EEPROM in the on-board charger function module through the on-board charger function module.

[0064] Among them, Electrically Erasable Programmable Read-Only Memory (EEPROM) is a non-volatile memory that can save data even when the power is off. Compared with traditional Electronically Programmable Read-Only Memory (EPROM), EEPROM can be erased and rewritten in the circuit, which makes EEPROM convenient for configuration update.

[0065] In one possible implementation, after writing the charging protocol conversion configuration information into the EEPROM in the on-board charger function module through the on-board charger function module, the developer can use a diagnostic tool or a programmer to read the EEPROM in the on-board charger function module to verify whether the charging protocol conversion configuration information has been correctly written to confirm the correctness of the charging protocol conversion configuration information.

[0066] Step 240: When the vehicle is charging, the charging protocol conversion configuration information and the charging configuration information are read through the on-board charger function module, and the charging pile is communicated according to the charging protocol conversion configuration information.

[0067] When the vehicle is charging, the vehicle control system identifies the charging protocol corresponding to the charging pile through the on-board charger function module; then, the vehicle control system reads the charging configuration information corresponding to the charging protocol through the on-board charger function module; then, the vehicle control system reads the charging protocol conversion configuration information through the on-board charger function module to obtain whether the vehicle contains a communication conversion unit to verify whether the vehicle supports the charging protocol.

[0068] For example, taking the above-mentioned charging configuration information as an example, which can indicate the configuration information of the national standard and the European standard involved in vehicle charging, after the vehicle control system identifies that the charging protocol corresponding to the charging pile is the European standard through the on-board charger function module, the charging configuration information corresponding to the European standard charging protocol can be read through the on-board charger function module; afterwards, the vehicle control system reads the charging protocol conversion configuration information through the on-board charger function module to obtain whether the vehicle contains a communication conversion unit. In the case where the vehicle contains a communication conversion unit, the vehicle can support the European standard charging protocol. Afterwards, the on-board charger function module can communicate with the charging pile through the charging configuration information corresponding to the European standard charging protocol and the communication conversion unit to charge the vehicle.

[0069] In summary, the scheme shown in the embodiment of the present application, during the configuration information writing process, writes the charging protocol conversion configuration information of whether the vehicle contains a communication conversion unit, as well as the charging configuration information of different charging protocols, into the on-board charger function module, so that the on-board charger function module can run on vehicles that support different charging protocols, and achieves the compatibility of the on-board charger function module with different charging protocols, thereby improving the applicability of the on-board charger function module. Among them, this scheme writes the charging protocol conversion configuration information into the EEPROM in the on-board charger function module, which can avoid the loss or error of configuration information due to external factors, and improves the stability and reliability of the on-board charger function module.

[0070] In addition, compared with solutions involving different on-board charger functional modules for different charging protocols, the on-board charger functional module of this solution is universal, which can avoid failures caused by incorrect assembly of the on-board charger functional module during vehicle assembly, thereby improving the efficiency of vehicle assembly.

[0071] Based on the above Figure 2 In the solution in the embodiment shown, in a possible implementation solution, the above step 220 can be implemented as follows:

[0072] Broadcast vehicle configuration information in the CAN network through the configuration module;

[0073] The vehicle configuration information is received through the on-board charger function module, and the charging protocol conversion configuration information and the charging configuration information are extracted from the vehicle configuration information.

[0074] Among them, after receiving the vehicle configuration information broadcast by the configuration module, the on-board charger function module can parse the above vehicle configuration information, identify and extract the vehicle configuration information related to the on-board charger function module.

[0075] In an embodiment of the present application, the configuration module can broadcast vehicle configuration information in the CAN network, so that the on-board charger function module can extract the charging protocol conversion configuration information and charging configuration information related to the on-board charger function module from the broadcast vehicle configuration information. This solution can improve the efficiency of the configuration module in sending vehicle configuration information and reduce the network resource consumption when the configuration module sends vehicle configuration information.

[0076] Based on the solutions shown in the above embodiments of the present application, in a possible implementation scheme, the above step 220 can be implemented as follows:

[0077] The configuration module extracts the charging protocol conversion configuration information and the charging configuration information corresponding to the on-board charger function module from the vehicle configuration information, and unicasts the charging protocol conversion configuration information and the charging configuration information to the on-board charger function module.

[0078] Exemplarily, the configuration module carries a specified identifier in the charging protocol conversion configuration information and the charging configuration information. At the same time, the identifier can only be recognized by the on-board charger functional module, avoiding the situation where the charging protocol conversion configuration information and the charging configuration information are received by other functional modules.

[0079] In an embodiment of the present application, the configuration module can send the charging protocol conversion configuration information and the charging configuration information to the on-board charger function module in a unicast manner. This solution can improve the accuracy of the configuration module sending the vehicle configuration information to the on-board charger function module through the CAN network, thereby saving the network resource consumption occupied by the CAN network when sending the vehicle configuration information, and improving the transmission efficiency when the CAN network sends the vehicle configuration information.

[0080] Based on the solutions shown in the above embodiments of the present application, in a possible implementation scheme, the above configuration information processing method further includes the following steps:

[0081] When an error occurs in the on-board charger function module reading the charging protocol conversion configuration information, a configuration request is sent to the configuration module through the on-board charger function module, where the configuration request is used to request to obtain the charging protocol conversion configuration information;

[0082] The configuration request is received through the configuration module, and the charging protocol conversion configuration information is unicasted to the on-board charger function module.

[0083] The above configuration request refers to a request sent by the on-board charger function module to the configuration module to resend the charging protocol conversion configuration information so as to verify again whether the vehicle contains a communication conversion unit.

[0084] Exemplarily, after receiving the configuration request sent by the on-board charger function module, the configuration module can resend the charging protocol conversion configuration information through the CAN network, and carry a specified identifier in the charging protocol conversion configuration information. The identifier can be recognized by the on-board charger function module. In other words, the resent charging protocol conversion configuration information can be received and processed by the on-board charger function module.

[0085] In an embodiment of the present application, when an error occurs when the on-board charger function module reads the charging protocol conversion configuration information, the on-board charger function module can request the configuration module to send the charging protocol conversion configuration information again via unicast; this solution can improve the accuracy of the on-board charger function module in reading the configuration information.

[0086] Based on the solutions shown in the above embodiments of the present application, in a possible implementation scheme, the configuration module is one of the following functional modules:

[0087] Body controller BCM functional module, vehicle controller VCU functional module.

[0088] Among them, the body control module (BCM) function module is an electronic control unit (ECU). The BCM function module is mainly used to manage the non-drive-related systems of the car, that is, functions unrelated to the vehicle's powertrain system. The BCM function module can be located in the central position of the vehicle to communicate with multiple subsystems.

[0089] Among them, the vehicle control unit (VCU) function module is a higher-level control unit. The VCU function module is mainly responsible for coordinating all subsystems of the vehicle, especially playing a core role in electric vehicles. The VCU function module can be integrated in the central control area of ​​the vehicle to better monitor and manage the operating status of the entire vehicle.

[0090] Based on the above embodiments, this embodiment shows that the configuration module can be a BCM functional module among multiple functional modules, or a VCU functional module among multiple functional modules. This solution realizes the reception and transmission of vehicle configuration information by reusing the existing functional modules in the vehicle control system, which can simplify the structure of the vehicle control system.

[0091] Based on the solutions shown in the above embodiments of the present application, in a possible implementation scheme, the vehicle configuration information includes one or more of the following information:

[0092] Charging protocol configuration information, on-board charger configuration information, battery management system configuration information, user interface configuration information, remote service configuration information, fault diagnosis configuration information, and safety configuration information.

[0093] The charging protocol configuration information may be the configuration information of the charging protocol corresponding to the sales area of ​​the vehicle. For example, if the sales area of ​​the vehicle is China, the charging protocol configuration information includes the charging protocol information supporting the national standard. For another example, if the sales area of ​​the vehicle is Europe, the charging protocol configuration information includes the charging protocol information supporting the European standard.

[0117] Based on the above embodiments, this embodiment shows a variety of contents corresponding to vehicle configuration information. For example, vehicle configuration information may include configuration information related to electric vehicle charging and configuration information for electric vehicle fault diagnosis. It is possible to uniformly configure different vehicle configuration information, improve the processing efficiency of various vehicle configuration information, and further expand the application scenarios of this solution, thereby improving the applicability of the above configuration information processing method.

[0118] Based on any one or more of the above embodiments, the embodiment of the present application proposes a method for an on-board charging assembly that is compatible with a communication conversion module through a CAN software configuration function, selects a main controller as the configuration module, writes the vehicle configuration information to the main controller, and the main controller broadcasts the configuration information to the CAN line. The on-board charger receives the CAN configuration information and filters whether there is a configuration of the communication protocol conversion module, and stores it in the internal EEPROM. Subsequently, it reads its own EEPROM to obtain whether there is a communication protocol conversion module, thereby achieving the purpose of compatibility with the communication protocol conversion module.

[0119] Please refer to Figure 3 , which shows a flow chart of a method for configuring a vehicle-mounted charging assembly compatible with a communication conversion module through a CAN software configuration function according to an exemplary embodiment of the present application. Figure 3 As shown, the method includes the following steps.

[0120] First, a controller is selected as the configuration main controller 301. The configuration main controller 301 may be a body controller BCM or a vehicle control unit VCU.

[0121] Secondly, when the vehicle is about to be offline, the diagnostic device 302 is connected to the configuration main controller 301 through the diagnostic port, and the diagnostic device 302 writes the vehicle configuration information of the vehicle into the configuration main controller 301. Among them, the vehicle configuration information includes charging protocol conversion configuration information and charging configuration information. The charging protocol conversion configuration information is used to indicate whether the vehicle contains EVCC, and the charging configuration information is used to indicate the configuration information of the European standard and the national standard involved in the vehicle charging.

[0122] Afterwards, the configuration main controller 301 sends the vehicle configuration information to various controllers of the entire vehicle, including the on-board charger 303, through the CAN network.

[0123] The on-board charger receives the charging protocol conversion configuration information and the charging configuration information sent by the configuration main controller 301, and stores the charging protocol conversion configuration information in the EEPROM. Each time it runs, the on-board charger reads the charging protocol conversion configuration information from the EEPROM to run different interactive logics.

[0124] It should be noted that the international fast charging protocol is different from the national standard fast charging protocol. For example, in the European standard fast charging protocol, the BMS interacts with the charging pile through PLC communication, while in the national standard fast charging protocol, the BMS interacts with the charging pile through CAN communication. The role of EVCC is to replace the BMS to interact with the European standard charging pile, convert the European standard PLC communication into CAN communication, and then transmit it to the BMS, so that the BMS is compatible with both national and European standard charging without modifying the software.

[0125] In summary, the above method can update the configuration information of each controller of the vehicle at the same time by configuring the main controller once, which simplifies the maintenance and update process of the vehicle and improves work efficiency. Using a unified configuration main controller can reduce the adaptation of multiple controller configurations during the development of diagnostic equipment, reducing costs and development cycles. By storing the charging protocol conversion configuration information in EEPROM and reading the configuration at each run, it can avoid configuration information loss or errors due to external factors, thereby improving the stability and reliability of the on-board charger software.

[0126] Exemplarily, the above method can achieve the compatibility of the on-board charger with the national standard and European standard charging protocols. Through the communication protocol conversion module and configuration management, the on-board charger can adapt to the charging requirements of different standards, thereby improving the flexibility and availability of the on-board charging assembly. By introducing the configuration master node and EEPROM storage, centralized management of vehicle configuration information is achieved. This can simplify the configuration process, improve management efficiency, and ensure the stability and reliability of configuration information. By storing configuration information in EEPROM, reliable reading and execution of data in various environments is guaranteed, improving the stability and reliability of the equipment.

[0127] In other words, this method can achieve compatibility with the national standard charging protocol and the European standard charging protocol in the on-board charger, and manage the configuration information of the entire vehicle by configuring the main node and the communication protocol conversion module, so as to execute different software requirements in different situations.
