电动汽车当前阶段的首要设计目标是获得与传统汽车相近的驾驶性能和续驶里程，且制造成本要控制在合理范围。为实现这一目标，提出了一种精简型无级变速机构，并对采用了固定速比减速器和精简型无级变速器的两种纯电动汽车的驾驶性能和能源利用率进行对比。结果表明，相比于固定速比减速器，精简型无级变速器提高了电机的工作效率且减少了电能消耗，同时整车制造成本和使用费用也有所降低。

The primary objective of electric vehicle for the present time is to attain the driveability and driving range similar to that of conventional vehicle, and control the manufacturing cost in a reasonable range. For this end, we put forward a streamlined continuously variable transmission (CVT) mechanism, and compare the driveability and energy utilization rate of two pure electric vehicles equipped with fixed speed ratio reducer and streamlined CVT respectively. The results show that compared with the fixed speed ratio reducer, the streamlined CVT increases operating efficiency of motor, reduces power consumption, meanwhile cut down vehicle manufacturing cost and TCO.
