The invention discloses a charging control method for a low-voltage storage battery, a vehicle control unit and a new energy commercial vehicle, and the charging control method for the vehicle control unit of the new energy commercial vehicle comprises the steps: controlling a battery management system corresponding to the low-voltage storage battery to be periodically awakened under the condition that the new energy commercial vehicle is in a power-off state; when the battery management system is awakened and it is detected that the low-voltage storage battery meets the remote charging condition, the key state and the charging state of the vehicle are obtained; and controlling the charging state of the low-voltage storage battery according to the key state and/or the charging state. According to the charging control method, the low-voltage storage battery can be charged in time when the low-voltage storage battery is lack of electricity, the problem that the vehicle cannot be normally started due to the lack of electricity of the low-voltage storage battery is avoided, and the intelligent charging control function of the low-voltage storage battery is achieved.

    本发明公开了一种低压蓄电池的补电控制方法、整车控制器和新能源商用车,用于新能源商用车的整车控制器,补电控制方法包括:在新能源商用车处于下电状态的条件下,控制低压蓄电池对应的电池管理系统周期性唤醒;在电池管理系统被唤醒且检测到低压蓄电池满足远程补电条件时,获取车辆的钥匙状态和充电状态;根据钥匙状态和/或充电状态控制低压蓄电池的补电状态。该补电控制方法能够在低压蓄电池亏电时及时为低压蓄电池补电,避免因低压蓄电池亏电导致的车辆无法正常起机的问题,实现低压蓄电池智能补电控制功能。
