Battery management system plays a very important role in new energy pure electric vehicles. At present, there are many problems in the integrated system composed of multiple modules in new energy pure electric vehicles, and the CAN bus communication between each control unit is complicated and lagging. In this paper, the CANoe/MATLAB collaborative simulation method is used to carry out experimental research. Firstly, based on MATLAB/Simulink simulation, the multi-module communication mode is constructed, and the interaction relationship between the modules is analyzed. Secondly, the multi-module communication architecture based on CAN bus is constructed, and the realtime accuracy of communication between modules is verified. The experiment proves that CANoe/MATLAB collaborative simulation can easily design a communication strategy suitable for distributed battery management system.
