Abstract: The Battery Management System BMS is an important part of the Electric Vehicle (EV) energy management. It provides important parameters of the vehicle control strategy. However, BMS works in a complex electromagnetic environment of the electric vehicle, therefore improving the Electromagnetic Compatibility (EMC) performance of the BMS is extremely essential to guarantee the vehicle safety and reliability. The electromagnetic environment of a Hybrid Electric Vehicle (HEV) and its coupling mechanism to the BMS is researched in this paper, and by the optimisation design the EMC performance of the BMS is greatly enhanced. Results show that the optimised BMS can be a good adaptation in the HEV complex electromagnetic environment.

Keywords: HEVs; hybrid electric vehicles; BMS; battery management system; EMC; electromagnetic compatibility; EMI; electromagnetic interference; vehicle energy management; vehicle control; optimal design.
