Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0040] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0041] Combined with Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a system for graphically configuring and automatically generating BMS upgrade firmware, which includes: a graphical interface, a custom parameter module, a firmware configuration module, an online compilation module, and a firmware management module; where:

[0042] The graphical interface is used to display the visual graphs of the custom parameter module, the firmware configuration module, and the online compilation module;

[0045] The online compilation module is used to automatically convert the user-defined configuration (parameter configurations of the custom parameter module and the firmware configuration module) into program code. Specifically: first define a standardized program code template, extract the configurable parameters in the template as software-configurable parameters, and automatically convert the code by replacing the parameters configured by the user in the software interface with the parameters in the standard program template. Further, compile and generate the firmware file (bin file) for BMS software upgrade. Specifically: call the open-source compilation toolchain to compile the generated code and generate a bin-format file that can be burned into the BMS board.

[0046] The firmware management module is used to manage the firmware files of the BMS software generated by compilation.

[0047] Using the present invention, the user can configure the basic parameters, functions, and protocol content of the BMS product through a graphical interface. After the configuration is completed, the system automatically generates structured C code according to the configuration, and the generated C code can be directly used to compile and generate a firmware file for BMS product upgrade.

[0048] The following details a system for graphical configuration and automatic generation of BMS upgrade firmware of the present invention:

[0049] 1. System working process:

[0050] In the embodiment of the present invention, the BMS program is modularly designed to form a standardized engineering template, and at the same time, the selectable functions and parameters are extracted and provided to the user, and converted into customizable parameters. The user can freely modify the function configuration and custom protocols (protocols such as UART, MODBUS, and CAN) to meet the personalized customization requirements of the BMS. The specific working process is as Figure 2 shown.

[0051] 2. Functions and parameters:

[0052] Different standard projects include different basic functions. This part of the functions is determined by the standard project and is an essential function. This part of the functions only provides configurable parameters. Different standard projects have supporting default parameters, and the user only needs to modify a small part of the parameters that need to be modified.

[0062]

[0063] Table 4 Other Parameters

[0064]

[0065] 3. Custom Message:

[0066] In the embodiments of the present invention, the message is the data format for communication between the BMS protection board and other devices. When the fixed messages provided by the standard project cannot meet the requirements, the user can generate the message format they need by customizing the message.

[0067] 3.1 CAN Message:

[0068] In the embodiments of the present invention, multiple CAN messages can be customized. The items that need to be configured for each message are as follows:

[0069] ① Configure the ID of the frame (non-repeating when there are multiple messages);

[0070] ② Frame type (standard frame, extended frame);

[0071] ③ Endian mode (big endian mode, little endian mode);

[0072] ④ Each CAN message has 8 bytes per frame, and the content can be fixed values or optional data items.

[0073] 3.2 Modbus Message:

[0074] The Modbus message has only one frame. The items that need to be configured are as follows:

[0075] ① Protocol ID;

[0076] ② Starting address;

[0077] ③The message content can be a fixed value or an optional data item, and the byte length shall not exceed the maximum length limit of Modbus protocol communication.

[0078] 3.3 UART Message:

[0079] In the embodiments of the present invention, the UART message can be customized into multiple frames, and each frame needs to configure the received message and the response message simultaneously. The items to be configured are as follows:

[0080] ①Endianness mode (big-endian mode, little-endian mode);

[0081] ②Check mode (CRC check, XOR check, sum check);

[0082] ③Check start byte;

[0083] ④The received message content is a fixed value;

[0084] ⑤The response message content can be a fixed value, an optional data item, or a check code.

[0085] The following introduces the specific working process of the system with reference to the attached drawings;

[0086] 1. Create a new firmware: As Figure 3 shown, fill in the project model, firmware name, and firmware version in sequence, and then click the OK button to add the firmware.

[0087] 2. Add custom parameters (optional operation): Refer to Figure 4 shown, the operation process includes: a. Select the original parameter; b. Enter the parameter alias; c. Modify the number of bytes, modification coefficient (multiple relationship with the original parameter), and offset (position offset value from the original parameter); d. Click the OK button to add the custom parameter.

[0088] 3. Add custom Bit type parameters: Refer to Figure 5 shown, the operation process includes: a. Enter the parameter name; b. Enter the number of bytes; c. Select the parameter item represented by each bit; d. Click the OK button to add the Bit type parameter.

[0089] 4. Basic function configuration: The operation process includes: a. Enter the firmware version; b. Select the cell type according to the type of battery pack cells; c. Select whether heating, current limiting, and CAN parallel operation functions are required; d. Set the basic parameters according to the battery pack parameters. The generated code is shown in Figure 6 shown.

[0090] 5. Custom CAN Message (Optional Configuration): The operation process includes: a. Enter the message ID; b. Select the frame type (standard frame / extended frame); c. Select the endian mode (big endian / little endian); d. Select the message content. The generated code can be seen in Figure 7 as shown.

[0091] 6. Custom Modbus Message (Optional Configuration): The operation process includes: a. Enter the communication protocol ID; b. Enter the starting address; c. Select the message content. The generated code can be seen in Figure 8 as shown.

[0092] 7. Custom UART Message: The operation process includes: a. Select the endian mode (big endian / little endian); b. Check mode (CRC check, XOR check, sum check); c. Enter the starting byte of the check; d. Enter the received message; e. Select the response message content.

[0093] 8. Submit for Generation: Submit the configuration file to the server.

[0094] 9. Wait for the server to compile and generate the firmware file: Convert the user's custom configuration into structured C code according to certain rules, and then use the standard project and the generated code file to compile and generate the bin file. The compilation process is completed by the background without the user's participation. The rules for generating structured C code refer to: converting basic parameters and functions into macros, or converting custom messages into code functions, etc.; for example, if a value is entered for the undervoltage protection value, the generated C code is "#define SC_CUV_Threshold 2700" (refer to Figure 6 shown in line 28 of Figure 7 as shown). After configuring the CAN protocol message, the corresponding generated C code is as

[0095] shown. After generating this C code, then use the compiler to compile this C code to generate the upgrade firmware that can be burned into the BMS board.
