Improvement in Storage System by Battery-Supercapacitor Combination in Electric Vehicles

The paper is basically a review of development of power unit for electrical transportation vehicle. This paper critically analyses the challenges which can be faced in EV’s effective and efficient power unit. It also throws light on application of supercapacitor application as power buffer in electrical vehicles. It also describes design and control requirements of supercapacitor power buffer. Two cases for simulation are presented where supercapacitor and battery are connected in shunt as well as trough power converter for optimum utilization of supercapacitor. Finally, simulation results are presented and analysed
