[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the 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 accompanying 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 to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0041] Combination 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, the system comprising: a graphical interface, a custom parameter module, a firmware configuration module, an online compilation module and a firmware management module; wherein:

[0042] Graphical interface for displaying visualization of custom parameter modules, firmware configuration modules, and online compilation modules;

[0043] The custom parameter module is used to customize the parameter names that need to be obtained and perform related operations on firmware custom parameters;

[0044] The firmware configuration module is used to select and modify the firmware's functional configuration and custom protocol; specifically includes: basic configuration unit, custom CAN message unit, custom Modbus message unit and custom UART message unit.

[0045] The online compilation module is used to automatically convert user-defined configurations (parameter configurations of custom parameter modules and firmware configuration modules) into program codes. Specifically, a standardized program code template is first defined, and the configurable parameters in the template are extracted as software configurable parameters. Automatic conversion into code means replacing the parameters in the standard program template with the user-configured parameters in the software interface. Furthermore, the firmware file (bin file) for BMS software upgrade is compiled and generated. Specifically, the open source compilation tool chain is called to compile the generated code and generate a bin format file that can be burned to the BMS board.

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

[0047] By using the present invention, users can configure the basic parameters, functions and protocol contents of BMS products 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 firmware files for BMS product upgrades.

The specific workflow is as follows Figure 2 shown.

[0051] 2. Functions and parameters:

[0064]

[0065] 3. Customized message:

[0069] ①Configure the frame ID (multiple messages cannot be repeated);

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

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

[0072] ④A CAN message consists of 8 bytes in one frame, and the content can be a fixed value or optional data item.

[0073] 3.2Modbus message:

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

[0075] ①Protocol ID;

[0076] ②Starting address;

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

[0078] 3.3UART message:

[0082] ③ Check the start byte;

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

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

[0085] The following is an introduction to the specific working process of the system in conjunction with the accompanying drawings;

[0086] 1. New firmware: Figure 3 As 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): See Figure 4 As shown, the operation process includes: a. Select the original parameter; b. Enter the parameter alias; c. Modify the number of bytes, the coefficient (the multiple relationship with the original parameter), and the offset (the position offset value with the original parameter); d.

The compilation process is completed by the background and does not require user 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" (reference Figure 6 After the CAN protocol message is configured, the corresponding generated C code is as follows Figure 7 After these C codes are generated, they are compiled by a compiler to generate upgrade firmware that can be burned into the BMS board.
