Abstract

In this paper, a fuzzy controller is constructed on the basis of the hybrid electric vehicle’s (HEV’s) batteries fast charging during regenerative braking. The proposed method is based on Mascc law and the mathematical relationship between open circuit voltage with the internal resistance model and charge efficiency. A closed-loop control system simulation model is accomplished in Matlab and the rate of electric energy recovery for HEV is calculated with different control strategy. It is shown that the rate of electric energy recovery with the fuzzy control strategy is increased by 8.41% compared with the constant current charge method in the same brake condition, thus the fuel economy is greatly improved.
