The invention provides a power battery overcharge protection method and device, a vehicle and a storage medium. The method comprises the following steps: acquiring a single voltage value of a vehicle power battery; judging whether the single voltage of the power battery is in an overvoltage state or not; and under the condition that the single voltage of the power battery is determined to be in the overvoltage state, the fuel battery of the vehicle is prohibited from being started. According to the method, starting of the fuel cell can be prohibited when it is determined that the single voltage of the power cell is in the overvoltage state, so that the fuel cell does not work and does not output power when the single voltage of the power cell is in the overvoltage state, the situation that the power cell is overcharged when the fuel cell charges the power cell is avoided, and the reliability of the power cell is improved. Forbidding the fuel cell to start can also reduce the frequency of emergency shutdown of the fuel cell in the scene, and prolong the service life of the fuel cell.

    本申请提供了一种动力电池过充保护的方法、装置、车辆和存储介质,该方法包括:获取车辆动力电池的单体电压值;判断动力电池的单体电压是否处于过压状态;在确定动力电池的单体电压处于过压状态的情况下,禁止车辆的燃料电池启动。该方法能够在确定动力电池的单体电压处于过压状态时,禁止燃料电池启动,使燃料电池在动力电池的单体电压处于过压状态的情况下不工作、不输出功率,避免燃料电池给动力电池充电造成动力电池过充的情况,禁止燃料电池启动还可以减少此场景下燃料电池紧急停机的频率,提高燃料电池寿命。
