Design of Hardware-in-the-Loop Test System for New Energy Vehicle Battery Management System

The new energy vehicle battery management system test platform built by hardware in the loop technology can verify the control strategy of the new energy vehicle battery management system, which is of great significance for reducing the test cost of the bench and the real vehicle and improving the development efficiency. In this paper, a hardware in the loop simulation target machine control model is designed to simulate the voltage, current, temperature and other parameters of the battery pack. Analyze and process the data collected by the battery management system based on the hardware in the loop, verify the control strategy of the battery management system, and verify that it can meet the simulation of most working conditions through testing, and further verify the correctness of the battery management system controller, and reduce the development cost.
