The embodiment of the invention relates to the technical field of automobile discharging, and discloses a discharging method, device and equipment for an electric automobile under high voltage and a storage medium. The high voltage lowering instruction comprises a non-emergency high voltage lowering instruction and an emergency high voltage lowering instruction; the emergency high-voltage command refers to a collision emergency high-voltage signal and a battery thermal runaway emergency high-voltage command; the whole vehicle controller controls the whole vehicle to send a high voltage lowering instruction to the battery management system and the motor controller; and when the motor controller receives the high-voltage lowering instruction, executing a target discharge mode corresponding to the high-voltage lowering instruction, and determining to perform active discharge and/or passive discharge. According to the technical scheme, active discharge and passive discharge are effectively combined according to the target discharge modes corresponding to non-emergency high voltage and emergency high voltage conditions, so that the reliability of discharge control is ensured.
本发明实施例涉及汽车放电技术领域,公开了一种电动汽车下高压的放电方法、装置、设备及存储介质,该方法包括:整车控制器接收下高压指令;下高压指令包括非紧急下高压指令和紧急下高压指令;紧急下高压指令指碰撞紧急下高压信号、电池热失控紧急下高压指令;整车控制器控制整车将下高压指令发送给电池管理系统和电机控制器;电机控制器接收到下高压指令时,执行与下高压指令对应的目标放电方式,确定进行主动放电和/或被动放电。应用本发明的技术方案,针对非紧急下高压和紧急下高压情况分别对应的目标放电方式,将主动放电和被动放电有效结合,以保证放电控制的可靠性。
