A hybrid approach to optimal electric drive train design

This paper describes the methodology for developing algorithms for optimal design of an electric drive train for electric bikes and evaluating their performance. The design methodology is validated using simulation and experimental results. The behavioral model of the electric drive train is developed and the performance of the drive train subject to varying battery sizes and motor ratings are evaluated. The effect of reducing battery voltage on the vehicle speed and performance which is essentially the behavior of the brushless DC motor is presented with simulation and experimental results. This simulation model is very useful for optimizing the battery rating, motor rating and estimating the Range of electric bikes. Simulation and experimental results are presented.
