The invention discloses a range extending type electric vehicle power assembly system. The range-extending type electric automobile power assembly system comprises a main lithium iron phosphate battery, a main lithium iron phosphate battery, an auxiliary lithium iron phosphate battery and an auxiliary lithium iron phosphate battery, the hydrogen fuel cell is used for supplying energy to the automobile or charging and supplying energy to the main lithium iron phosphate battery when the electric energy of the main lithium iron phosphate battery is insufficient; and the auxiliary lithium iron phosphate battery is used for supplying energy to the automobile when the automobile accelerates suddenly so as to realize acceleration of the automobile. According to the technical scheme, the problem of mileage anxiety is solved through the range extending function of the fuel cell and the power recycling function, and a driver does not need to worry about the endurance problem in the driving process of the electric vehicle. Moreover, the motor can be driven mainly by the main lithium iron phosphate battery and the hydrogen fuel battery, energy can be directly supplied, the main lithium iron phosphate battery can be charged, the hydrogen fuel battery does not participate in acting when only playing a charging role, the hydrogen fuel battery is not damaged in a high-power and high-load running state, and the service life of the hydrogen fuel battery can be prolonged.

    本申请公开了一种增程式的电动汽车动力总成系统。该增程式的电动汽车动力总成系统包括:主磷酸铁锂电池,用以为所述汽车供电;氢燃料电池,用以在所述主磷酸铁锂电池的电能不足时为所述汽车供能,或者为所述主磷酸铁锂电池充电供能;辅磷酸铁锂电池,用以在汽车急加速时为所述汽车供能以实现汽车的加速。本技术方案中,通过燃料电池的增程,以及动力回收功能解决了里程焦虑问题,驾驶员在电动车的行驶过程中不需要担忧续航问题。不仅如此,电机的驱动主要靠主磷酸铁锂电池,氢燃料电池即可直接供能,又可对主磷酸铁锂电池充电,氢燃料电池在只起充电作用中不参与做功,在大功率高负载的行驶状态下,对氢燃料电池没有损伤,可以延长氢燃料电池的使用寿命。
