Development of a HiL Test Bench for Battery Management Systems

  • The growth in battery electric vehicle sales increases the need for Battery Management Systems (BMS). This work shows a deep dive into the BMS and the development of a hardware in the loop test-bench for such electronic control units. The test bench will be used for teaching and the development of new functions for BMS. This work also serves as a basis for teaching in the field of BMS and covers the most common functions of a BMS like state estimation, e.g. State of Charge, current, temperature and voltage measurements and balancing methods. Additionally, this work shows how data for the parameterization of the BMS is determined using battery cycling measurements and electrochemical impedance spectroscopy (EIS). All this information is used to create an accurate battery pack model for hardware in the loop simulation. The battery model runs on a cell emulator, connected to the BMS. With a graphical user interface, different test scenarios can be applied. Students of the course can insert errors and investigate the behaviour of the BMS.
