N2 - How to use the lithium-ion power battery effectively, how to improve the discharging efficiency and the cycle-life of the power battery is a hotspot of research in battery-electric vehicle(BEV) field. The fuzzy comprehensive evaluation method is used to evaluate the factors that influence the discharging efficiency and the cycle-life of the power battery.The demanded dynamic performance is judged by average value of traction pedal in a fixed period; The weighting coefficients are confirmed according to the relative importance of each parameter,and the intelligent control strategy is made according to the judging result. The intelligent control strategy is loaded to the pure vehicle controller and verified by real vehicle.The result indicates that the intelligent control strategy made by using the fuzzy comprehensive evaluation method can prevent the battery to be overcurrent or overdischarge. The discharging efficiency of the battery is improved , and the range of vehicle is lengthenned under the public traffic mode.
