The invention relates to the technical field of vehicles, in particular to a vehicle high-voltage power-on and power-off control method and device, a vehicle and a storage medium, and the method comprises the steps that a direct-current charging ignition signal of the vehicle, the current state of a battery management system, an alternating-current charging ignition signal, a key ignition signal and a remote high-voltage connection request signal are collected; matching a power-on and power-off control strategy of the high-voltage system according to the direct-current charging ignition signal, the current state of the battery management system, the alternating-current charging ignition signal, the key ignition signal and the remote high-voltage connection request signal; and performing high-voltage power-on and power-off control on the high-voltage system according to the power-on and power-off control strategy of the Therefore, the problems that due to the fact that high voltage and large current of a vehicle are suddenly changed in the power-on and power-off process of the high-voltage system, safety accidents can be caused by the improper power-on and power-off sequence, the reliability of the high-voltage system is reduced, and the service life is shortened are solved, a more accurate high-voltage power-on and power-off control method is provided, and the reliability and safety of the system are enhanced.

    本申请涉车辆技术领域,特别涉及一种车辆高压上下电控制方法、装置、车辆及存储介质,其中,方法包括:采集车辆的直流充电点火信号、电池管理系统的当前状态、交流充电点火信号、钥匙点火信号和远程高压连接请求信号;根据直流充电点火信号、电池管理系统的当前状态、交流充电点火信号、钥匙点火信号和远程高压连接请求信号匹配高压系统的上下电控制策略;根据高压系统的上下电控制策略对高压系统进行高压上下电控制。由此,解决了由于车辆在高压系统上下电过程中存在高压电与大电流突变现象,上下电的顺序不当会造成安全事故,导致高压系统可靠性降低、寿命缩短的问题,提供更精确的高压上下电控制方法,增强系统的可靠性与安全性。
