An improved electric vehicle regenerative braking strategy research

Abstract

How to protect the battery from overcharging and recover regenerative energy effectively are the key issues during the braking control process for electric vehicle. Among the existed braking control strategies, most of them didn't consider the battery overcharging problem. according to vehicle's braking force safety requirements on wheels and battery state of charge(SOC), both of a braking force distribution controller (BFDC) and a braking force regulator (BFR) are designed respectively, followed by the proposal of a practical electric vehicle regenerative braking strategy that considering battery SOC. Finally, experiments are carried on ADVISOR simulation platform, and results show that the vehicle obtains a good anti-overcharging ability. © 2012 Springer-Verlag GmbH.
