Research on Road Test of Auxiliary Power Hev Battery-Behavior

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%.
