The invention relates to a long-endurance battery replacement type pure electric vehicle. According to the pure electric vehicle, on-off conversion can be conveniently achieved to replace a power battery pack at the moment when the vehicle is stopped in the running process of the vehicle. According to the scheme, a power battery pack is divided into a power battery pack A and a power battery packB which have the same capacity and voltage and are independent, and when the power battery pack A supplies power to a driving motor, the power battery pack B charges the driving motor through a vehicle-mounted coreless permanent magnet generator; when the electric quantity of the power battery pack A is reduced to the set capacity, the vehicle-mounted controller can be controlled by a change-overswitch to automatically change the battery pack supplying power to the driving motor from the power battery pack A to the power battery pack B to supply power to the driving motor at the moment of parking; and the power battery pack A is converted to the vehicle-mounted coreless permanent magnet generator by the vehicle-mounted controller to continue to charge the vehicle-mounted coreless permanent magnet generator during running. The endurance mileage of the pure electric vehicle is effectively prolonged, the charging frequency is reduced, and the problem of difficult charging is relieved.
本发明涉及一种长续航换电式纯电动汽车,采取了汽车在行驶过程中能够利用车辆停车瞬间可以方便实现开关转换更换动力电池组的纯电动汽车。该方案动力电池组被分置为两组容量、电压相同且独立的动力电池组A和动力电池组B,在动力电池组A给驱动电机供电的时候,动力电池组B则利用车载无铁芯永磁发电机为其充电;待动力电池组A电量下降到设定容量时,可利用停车瞬间,通过转换开关控制车载控制器将给驱动电机供电的电池组由动力电池组A自动转换至由动力电池组B给驱动电机供电,而动力电池组A则由车载控制器转换至车载无铁芯永磁发电机在行驶中继续为其充电。有效延长了纯电动汽车的续航里程,减少了充电次数,缓解了充电难的问题。
