A comparative study of different control strategies of On-Board Battery Chargers for Battery Electric Vehicles

摘要

On-Board Battery Charger is one of the key components required for the emergence and acceptance of Battery Electric Vehicles (BEVs). The control strategy of the battery charger plays an important role in the development of BEVs. Therefore, the proper selection of this control strategy can significantly improve the performance of the BEVs during charging mode from the grid. In this paper, a comparative study of different control strategies of on-board battery chargers for BEVs is presented. In this research, three control strategies are designed and applied to control the power flow of the on-board battery charger during charging mode from the ac grid. These control strategies are hysteresis current control (HCC), Proportional-Integral Control (PIC) and Proportional-Resonant Control (PRC). These control strategies are designed and analyzed by using MATLAB/Simulink. The simulation and experimental results are provided.
