摘要
以100Ah的锰酸锂锂离子二次电池锂离子电池组和30kW交流电机组成了动力系统,研制了MGL6486EV电动汽车。电池组的电压为304V,能量为37kWh,电池组采用了智能管理系统(BMS)和均衡系统。电动机采用全数字适量控制,并具有刹车能量回收和防溜车功能。在充电时智能充电机始终与BMS保持通信联系,以保证电池组安全快速充电。车辆最高车速可达117km/h,0~50km/h加速时间为6·80s,50~80km/h加速时间为7·34s,爬坡度超过20%,续驶里程为204km,百公里耗电仅为19kWh。到目前为止该车辆已运行5万多km。
Powered by spinel LiMn_2O_4-based 100Ah Li-ion secondary battery, an electric vehicle (EV) named MGL6486EV was developed with a 30kW AC motor. The total voltage of the battery system is 296V , and the total energy is 37 kWh. Intelligent battery management system (BMS) and the balancing system were adopted. Digital control has been applied to the motor, which serves such functions of braking energy regeneration and sliding prevention. The intelligent charging machine keeps all-time communication with the BMS...
