Abstract

Increments in vehicle emission and demand for fossil fuels, making vehicle manufacturers around the world to look forward into alternative ways in introducing new electric vehicle model that would vastly capture the market. Best strategy of OEM now is to make competitive edge in the market and satisfy customer demands on the basis of range and pricing of the vehicle. Various EV part manufacturers producing the parts at different specification and price level. Where OEMs are trying to tune up vehicle at highly efficient performance (in the sense of range) and at lower pricing. EV’s are facing challenges in mileage issue. Range of the EV is mainly depending on the performance of electric drive systems such as battery, traction motor, controller and gearbox. For EV OEMs it is most important task to select best substitute parts amongst various alternatives for their EV to improve efficiency of  the vehicle. This study focuses on improving the efficiency of the EV by selecting efficient battery amongst various alternatives and attributes with the help of decision making and optimization techniques. The procedure is divided in 3 parts. First is data collection of battery alternatives available in market and their attributes, second is to use of hybrid MCDM Ahp-Topsis technique and finally validate them by cross checking against actual vehicle level testing of the part. We have selected efficient battery with the help of Ahp and Topsis methods amongst six alternatives and four attributes of the batteries.
