Battery management system module development software integration method

Abstract

The invention discloses a battery management system module development software integration method. The problems of software development coupling and function extension difficulty in the prior art aresolved. The method comprises the following steps of S1, performing hierarchical and modular management on BMS software; defining a data management layer DIL which is responsible for data management of the modules and data interaction between the modules; s2, unifying interfaces among the modules, and defining interface functions of DIL and interface function names of the modules; s3, calling a module interface to perform data interaction; acquiring and releasing data defined in DIL using a unified interface function. The software is modularly managed, the coupling relation between software isrelieved, synchronous development, independent operation and debugging of all functional modules of a research and development team can be coordinated, and finally an integration function integrationtest is carried out. The modules are connected through DIL, different people can be allowed to achieve the same function in different methods only by keeping interface definition between the modules,and compatibility and function expansibility are improved.

Description

technical field [0001] The invention relates to the field of software development and integration, in particular to a battery management system module development software integration method. Background technique [0002] With the development of electric vehicles, the requirements for batteries, the core components of electric vehicles, are getting higher and higher. At the same time, as the industry pays more and more attention to functional safety, the management system control of batteries is becoming more and more complicated, and the complexity of software control is getting higher and higher. The higher the rate, the larger the amount of software code. The R&D team focuses on the research, development and testing of battery applications. However, the current BMS software architecture adopts a process-oriented application execution system, and often one person develops the software used for a project, resulting in low code reuse rate, high coupling between modules, poo...
