The invention provides an electric vehicle and a control method and device thereof, and the method comprises the steps: recognizing whether a main positive contactor is in an off state or not; and under the condition that the main positive contactor is in the off state, when the voltage of the high-voltage loop is greater than or equal to the first preset voltage, controlling a voltage converter to release the electric energy of the high-voltage loop into the storage battery, and recycling the electric energy discharged by high voltage into the storage battery. Thus, waste of the electric energy is effectively reduced, and the user experience is improved.

    本申请提出一种电动汽车及其控制方法和装置,其中,方法包括:识别主正接触器是否处于断开状态;在主正接触器处于断开状态的情况下,在高压回路电压大于或等于第一预设电压期间,控制电压变换器将所述高压回路的电能释放至蓄电池中,通过将高压泄放的电能回收至蓄电池中,有效减少电能的浪费,提升用户体验。
