Role of Motor Mass Reduction in the Performance of EV, HEV and FCV

The end consumers of EV, HEV and FCV need better fuel efficiency, drive range, cost effective without any compromise in comfort and luxury and the government bodies require independency on foreign oil, better carbon footprint and sustainability in transportation. It has also been observed that the weight of vehicles is increasing from one generation to the next generation. Heavier the vehicle more will be the fuel consumption and emission. So mass reduction of drive train components has become necessary to provide space for performance improvement of the vehicles. The advancement in the area of material technology, casting technology and use of lightweight materials has paved the way for the motor mass reduction. With the help of simulation on NREL ADVISOR small car with three dive train technology EV, HEV and FCV and conventional vehicle on three drive cycle HWFET, US06 and UDSS, this paper investigates how the performance of HEV, FCV and EV get affected and by the motor mass reduction of these vehicle while keeping other vehicle parameters unchanged.
