Experimental verification of regenerative braking characteristics by applying different motor armature voltage

Abstract

Simpler design of control system is the key advantage of DC motor. In recent decade, however use of dc motor in battery-operated electric vehicles (BEV) are declined spectacularly. Without significant improvement of efficiency of such system the use of dc motor in BEV will be objectionable. Regenerative braking is the possible way to improve the efficiency. In this paper a novel regenerative braking mechanism for electric vehicles based on DC motor is proposed. The performance of the proposed braking system has been evaluated experimentally for different motor armature voltage. For this a prototype model of BEV has been used. Simulation results show that the proposed regenerative braking technique is feasible and effective. Also this research provides a new possibility of cost effective equipments and simplest system for regenerative braking to improve the drive distance of electric vehicles.
