The invention provides a control method and device of an electric vehicle, a vehicle control terminal and a storage medium. The control method comprises the following steps: when a thermal runaway signal of a first battery system is obtained, controlling a second battery system to perform self-inspection; obtaining a self-checking signal of a second battery system; if the self-checking signal is normal, controlling the second battery system to start to supply power to the PDU; and controlling the PDU to supply power to the whole vehicle cooling system, and starting the whole vehicle cooling system to cool the first battery system. When the thermal runaway of the power battery system is detected, the other battery system supplies power to the PDU, and the whole vehicle cooling system is started to quickly and actively cool the power battery system, so that the thermal diffusion can be greatly inhibited, further expansion of the thermal diffusion can be effectively avoided, the harm of the thermal diffusion can be effectively reduced, and the service life of the power battery system is prolonged. And the safety of the electric automobile is improved.

    本发明提供一种电动汽车的控制方法、装置、车辆控制终端及存储介质。上述控制方法包括:当获取得到第一电池系统的热失控信号时,控制第二电池系统进行自检;获取第二电池系统的自检信号;若自检信号为正常,则控制第二电池系统启动为PDU供电;控制PDU为整车冷却系统供电,并启动整车冷却系统为第一电池系统降温。本发明当检测到动力电池系统热失控时,由另外一路电池系统为PDU供电,启动整车冷却系统对动力电池系统进行快速主动降温,可以对热扩散起到极大的抑制作用,能有效避免热扩散的进一步扩大,可有效降低热扩散的危害,提高了电动汽车的安全性。
