Power management strategy for battery electric vehicles

Abstract

This study presents a novel power management strategy (PMS) for a small urban electric vehicle. Enhancing battery electric vehicles driving range and their batteries’ lifetime are possible through developing a more effective PMS for them. Fuzzy logic control (FLC) is proposed to control the power control unit (PCU) of the battery management system. The control devices used are verified and experimented by simulations to evaluate their performance using the MATLAB software. The good performance of FLC can be observed in terms of settling time and peak overshoot from the simulations result. The simulation results show that the proposed PCU can decrease the energy loss inside the battery and increase the battery lifetime.
