Example Embodiment

[0039] Example 1

[0040] Such as figure 1 As shown, a method for configuring a vehicle communication protocol for a battery management system includes the following steps:

[0041] (1) Pre-encode all battery information in the BMS to generate a system application library; for example, the code corresponding to voltage is 0001, the code corresponding to current is 0002, and the code corresponding to SOC is 0003, etc.;

[0042] (2) Configure the content of the vehicle communication protocol;

[0043] (3) Call the battery information in the system application library according to the content of the vehicle communication protocol;

[0044] (4) Generate the vehicle communication protocol content code from the called battery information.

[0045] Wherein, the content code is a code that conforms to the vehicle communication protocol format, and is uploaded to the external device through the vehicle communication protocol.

[0046] Wherein, the content of the vehicle communication protocol incl...

Abstract

The invention discloses a battery management system full-vehicle communication protocol configuration method. The method comprises the following steps: carrying out unique coding on all battery information in a BMS (battery management system) to generate a system application library; carrying out configuration on the content of a full-vehicle communication protocol; calling the battery information in the system application library according to the content of the full-vehicle communication protocol; and enabling the called battery information to be generated into full-vehicle communication protocol content codes. According to the method, for different full-vehicle communication protocols, software code of a full-vehicle communication module at the bottom layer does not need to be modified, thereby reducing project development time and workload, improving project development efficiency and quality, improving confidentiality of the software code and reducing complexity of project development. The invention also provides a battery management system full-vehicle communication protocol configuration system, which comprises a system application library generation module, a protocol content configuration module, a battery information calling module and a protocol content code generation module.

Description

【Technical field】 [0001] The invention relates to the field of battery management, in particular to a method and system for configuring a vehicle communication protocol in a battery management system. 【Background technique】 [0002] With the rapid development of the new energy industry, the application range of BMS (battery management system) is becoming wider and wider, and there are more and more project developments. In the actual project application process, different projects will have different vehicle communication protocols, and the ID, content, and period of each frame of data are also different. Therefore, project engineers need to modify software program codes for different customer projects, which increases the complexity of project development, and at the same time, the development efficiency is not high. 【Content of invention】 [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and propose a method ...
