Study on regenerative braking of electric vehicle

This paper discusses the regenerative braking system for electric vehicle (EV) that performs regenerative energy recovery based on analytical deduction of several regenerative braking systems with the microscopic view of pulse width modulation (PWM) driving, a constant regenerative current control scheme is proposed, thereby providing improved performance and the energy recovery efficiency at minimum cost. Experimental results of EV show that the proposed regenerative braking control strategy has not only excellent control performance, but also make the very significant energy saving possible.
