With the deterioration of the air pollution, growing public concerns over the exhaustion of global fossil energy and the explosive growth of passenger vehicles, the improvement and popularity of electric vehicles (EVs) have increased in market share. The primary goal of EV powertrain design is achieving the same performance, e.g. launching and driving range, as that of Internal Combustion Engine vehicles. To realize this target, a novel propulsion system is proposed in this paper. A comparison of driving performance and energy saving are completed among single reduction, continuously variable transmission (CVT) and proposed system on EVs. The simulation results show that the optimized motor propulsion system has a significant improvement on battery energy saving, range extension and vehicle cost.
