Battery-to-Wheel Efficiency of an Induction Motor Battery Electric Vehicle with CVT and Adaptive Control
This paper addresses inefficiencies in the power-train of an Induction Motor (IM) driven battery electric vehicle. The paper provides a new drive-train and strategy solution, and a comparative study, to demonstrate an overall battery-to-wheel efficiency gain. A continuously variable transmission is coupled with an IM drive and is simulated using an adaptive control algorithm. Battery DC-Watt hours per km driven is used to test the overall battery-to-wheel efficiency. A comparative study of battery-to-wheel efficiency is then preformed. Results of this paper show an overall increase in battery-to-wheel efficiency in the FTP-75 drive cycle when using a CVT in the two vehicles modelled.
