The invention discloses an extended-range electric vehicle charging system, a charging control method and an extended-range electric vehicle, and belongs to the field of extended-range electric vehicles. When the temperature of the power battery is lower than a temperature threshold value and the power battery self-heating system cannot supply power to the battery self-heating system, the range extender can supply power to the battery self-heating system. Therefore, the battery self-heating system increases the temperature of the power battery. In this way, it can be guaranteed that the temperature of the power battery is kept at a certain temperature when the environment temperature is low, so that the range extender can charge the power battery conveniently, it is guaranteed that the power battery has enough electric quantity, the situation that the whole vehicle cannot work normally due to power interruption caused by electric quantity reduction of the power battery is avoided, and the reliability of the vehicle is improved.
本申请公开了一种增程式电动车充电系统、充电控制方法及增程式电动车,属于增程式电动车领域;在动力电池温度低于温度阈值且动力电池自加热系统无法为电池自加热系统供电时,增程器能够为电池自加热系统供电。以使电池自加热系统提高动力电池温度。这样能够保证在环境温度较低时,动力电池的温度保持一定温度,以便于增程器可以为动力电池进行充电,保证了动力电池具有足够的电量,避免了动力电池电量降低造成整车动力中断无法正常作业的情况,提高了车辆的可靠性。
