The embodiment of the invention provides a power battery charging control method, a battery management system, a medium and equipment, and the method comprises the steps: receiving the temperature, collected by each temperature sensor, of a preset position in a battery energy distribution unit when a power battery is charged; a corresponding temperature sensor is mounted at a preset position of the battery energy distribution unit; determining a target temperature according to the plurality of collection temperatures; whether the target temperature meets a safe charging condition or not is judged, and if not, a corresponding safe charging action is executed; thus, a temperature sensor is arranged at the preset position of a battery energy distribution unit (BDU), the temperature of the preset position of the BDU is collected in real time in the battery charging process, whether the battery meets the safe charging condition or not is judged according to the temperature of the BDU, and if not, the safe charging action is executed; the restriction of the BDU temperature on the charging process is reduced under the condition of large-current and high-rate charging, and the charging success rate is improved.

    本发明实施例提供了一种动力电池充电控制方法、电池管理系统、介质及设备,方法包括:在动力电池充电时,接收由各温度传感器采集的电池能量分配单元中预设位置的温度;所述电池能量分配单元的预设位置处安装有对应的温度传感器;根据多个采集温度确定目标温度;判断所述目标温度是否满足安全充电条件,若不满足,则执行对应的安全充电动作;如此,在电池能量分配单元BDU的预设位置处设置温度传感器,在电池充电过程中,实时采集BDU预设位置处的温度,根据BDU温度判断电池是否满足安全充电条件,若不满足,则执行安全充电动作,确保在大电流高倍率的充电情况下降低BDU温度对充电过程的制约,提高充电成功率。
