The invention provides a method and device for controlling battery charging, a vehicle and a storage medium. And under the condition that the voltage out-of-range fault occurs in the charging process of the target battery in the target vehicle, the target battery is charged through the first voltage, the actual charging voltage of the target battery is tested, and whether the voltage out-of-range fault actually occurs in the target battery or not is determined. When the target battery cannot be normally charged, the actual charging voltage is greater than the first voltage. And therefore, the charging voltage of the target vehicle is increased, and the power battery is controlled to charge the target battery by adopting the second voltage. Therefore, when the target battery really has a voltage out-of-range fault in the charging process, the charging voltage of the power battery is enabled to be greater than the actual charging voltage of the target battery by regulating and controlling the charging voltage of the target battery, so that the normal charging requirement of the target battery is met. In this way, the target battery is not in an overcharge state for a long time in the charging process, and fire disasters or explosions caused by generation of excessive heat can be avoided.

    本申请提供控制电池充电的方法、装置、车辆及存储介质。在目标车辆中的目标电池在充电过程中发生电压超范围故障的情况下,通过第一电压向目标电池充电,来试探目标电池的实际充电电压,确定目标电池是否真正发生电压超范围故障。在目标电池无法正常充电时,表明实际充电电压大于第一电压。对此,目标车辆增加充电电压,控制动力电池采用第二电压向目标电池充电。这能够确保目标电池在充电过程中真正发生电压超范围故障时,通过调控向目标电池的充电电压,使得动力电池的充电电压大于目标电池的实际充电电压,以满足目标电池的正常充电需求。这样,目标电池不会在充电过程中长时间处于过充状态,能够避免产生过多的热量而引发火灾或爆炸。
