The invention discloses a vehicle power battery thermal runaway processing method and system, a controller and a vehicle. The vehicle comprises a super capacitor, and the method comprises the steps that when it is detected that a power battery has the thermal runaway risk, the vehicle is controlled to be powered off, and the power battery is controlled to be separated from the vehicle; and starting the supercapacitor as a driving power supply of the vehicle, so that the vehicle runs to a separation position far away from the power battery. Therefore, after thermal runaway of the power battery occurs and the power battery is separated from the vehicle, the vehicle is driven by the super capacitor to be away from the power battery falling area, and the risk that the vehicle is ignited by the thermal runaway power battery is reduced.

    本发明公开了一种车辆动力电池热失控处理方法、系统及控制器、车辆。其中,车辆包括超级电容器,该方法包括:当检测到动力电池存在热失控风险时,控制车辆下电,并控制动力电池从车辆脱离;启用超级电容器作为车辆的驱动电源,以使车辆行驶至远离动力电池的脱离处。由此,能够在动力电池发生热失控,动力电池脱离车辆后,通过超级电容驱动车辆远离动力电池掉落区域,降低热失控动力电池引燃车辆的风险。
