The invention discloses a high-voltage discharging method and device for a power battery, a vehicle and a storage medium, and the method comprises the steps: detecting the charging state of the vehicle, and charging the power battery through charging equipment when the charging state of the vehicle meets the high-voltage condition of a discharging loop; controlling the power battery to charge the standby power supply, and detecting the current electric quantity of the power battery; and when the current electric quantity of the power battery is larger than the preset electric quantity, controlling the power battery to supply power to the vehicle-mounted heating device. Therefore, the problem that when the environment temperature is low, quick charging is carried out, warm air is started at the same time, and consequently the risk of power shortage of a power battery is caused is solved, it is guaranteed that low-temperature quick charging is carried out smoothly, and the functional reliability and user experience of electric vehicle low-temperature quick charging are improved.

    本申请公开了一种动力电池的高压放电方法、装置、车辆及存储介质,其中,方法包括:检测车辆的充电状态,并在车辆的充电状态满足放电回路高压条件时,通过充电设备为动力电池充电;控制动力电池为预备电源充电,并检测动力电池的当前电量;在动力电池的当前电量大于预设电量时,控制动力电池为车载加热装置供电。由此,解决了在环境温度较低时进行快充,同时开启暖风,导致动力电池亏电的风险的问题,保证低温快充的顺利进行,提升电动车低温快充的功能可靠性和用户体验。
