The on road performance of an Electric Vehicle is, to a large extent dependent on the performance of the drive train. The drive train determines how efficiently the energy in batteries is used to meet the driving requirements on road. The importance of efficiency is well known. With a ‘limited’ energy storage availability on board, it is important to see that the conversion of watt hours to kms happens in the most efficient manner. Also, in order to make driving simple and offer the best ‘on road’ convenience to customers, it is necessary to understand driving patterns and preferences of customers. This paper details the optimization of a drive train and development of ‘driving modes’ for an electric vehicle for use in India and Europe.
