Abstract Based on the requirement of output voltage of battery cell in battery management system (BMS) testing platform, we designed the battery cell simulator project. On the strength of analysis of current and voltage ripple with the volt-second balance principle, we simulated the bi-directional half-bridge DC-DC current by Matlab/Simulink and analyzed the influence of inductance, PMW frequency and duty ratio to voltage ripple. Several tests were carried out including output voltage accuracy test, dynamic response time test and system consistency test. The results showed that the precision of output voltage is within 0.2% and dynamic response is kept within 100 ms. Moreover, well consistency was achieved in different cell simulators. The experimental results indicate that the cell simulator conforms to the practical application and the implementation for the simulator provides prerequisites for the BMS test platform.
