混合动力电动汽车蓄电池特性的路试研究

Research on Road Test of Auxiliary Power Hev Battery-Behavior

针对提高蓄电池驱动能力问题,提出了一种将蓄电池的能量全部用于驱动电动汽车的辅助混合动力配置方式.对纯电动、辅助混合动力2种方式下蓄电池工作特性进行了道路实验对比,包括匀速、加速条件下充放电电流与电压特性的比较及一次充电续驶里程的比较.实验表明,辅助混合动力配置方式可以有效地缓解蓄电池的电压下降,使电动汽车提高10%续驶里程.

Propose a kind of auxiliary-hybrid configuration which make all the accumulator cell energy for driving the electric vehicles to improve the drive capability of accumulator. Through contrastively analyzing with electromotion and auxiliary-hybrid, the battery behavior of road test was studied. The test includes comparing of the battery characteristics under charge-discharge current and voltage on condition of even pace and acceleration, and also the comparing of one time charge current of the driving range. It comes to the conclusion that auxiliary hybrid configuration can reduce rapid declining of the battery voltage effectively and increase the driving range of electric vehicles by an additional 10%.
