Component selection for an electric vehicle: A review

Electric vehicles are widely used for pollution free transportation but it has been observed that distance travelled by battery operated electric vehicle is very less as compared with the other fuel powered engine and poor regenerative energy recapturing from the vehicle's kinetic energy. There are so many types of losses in power converter which increase consumption of battery energy. For increment of distance travelled by electric vehicles and increment of recapturing of regenerative energy we have to improve performance of all component used in electric vehicle like electric motor, power converter and energy storage system like battery or ultra-capacitor. This paper presents comparative study of all components used in an electric vehicle. This paper also concluded that which drive or converter is suitable for electric vehicle is being proposed. Best coordination of all components can lead to optimize power consumption in electric vehicle. Energy dissipated in power train during the operation of conversion from electrical energy to mechanical energy and vice-versa should be minimize, it cans be achieved only by using a converter whose efficiency is high like interleaved boost converter. There are various methods of modifying power converter to get more efficiency and increased power rating is explained, like using multi model method of boost converter.
