System Design and Simulation on Powertrain of Electric Vehicle

With the issue of environmental pollution and energy crisis worsening day by day, the researches and applications of low-pollution and high energy-efficient electric vehicles have become the research trend in the automotive area nowadays. On the basis of analyzing the requirements of pure electric vehicles’ drive motors and power batteries, this paper makes a reasonable selection of the basic parts’ type of pure electric vehicles’ powertrain and the parameters matched. The matching parameter is proved to be reasonable by simulation.
