The invention discloses a charging method for a power battery during a hydrogen energy automobile key in an OFF gear state. The method comprises the steps: carrying out intelligent charging when the key is in the OFF gear state: judging whether an electric quantity of a power battery generated by a battery management system selects to supplement electricity or not; before charging, sending charging information to T-BOX, and using a cloud end to remind a user that a mobile phone APP end confirms whether charging is carried out currently or not; and during charging, sending charging informationto the T-BOX, and using the cloud end to notify the user mobile phone APP end. And if a charging fault occurs in an intelligent charging process, a vehicle control unit sends a charging high-voltage state to a power battery and fuel cell stack management system and sends charging fault information to the T-BOX, the cloud end reminds the user mobile phone APP end and the vehicle control unit entersa dormant state after charging high-voltage power-off is completed, and charging is ended. After the charging method is adopted, when the automobile key is in the OFF gear state, the power battery isintelligently charged, and therefore a problem that the automobile cannot be started due to feeding of the power battery is solved.
本发明公开氢能汽车钥匙处于OFF档状态时动力电池的充电方法，钥匙处于OFF档状态时，进行智能充电：判断电池管理系统所发出的动力电池电量选择是否补电；补电前，发送充电信息至T‑BOX，云端提醒用户手机APP端确认当前是否充电；充电时，发送充电信息至T‑BOX，云端通知用户手机APP端。智能充电过程中若出现充电故障，整车控制器发送下充电高压状态给动力电池、燃料电池电堆管理系统，同时发送充电故障信息至T‑BOX，云端提醒用户手机APP端，充电高压下电完成后，整车控制器均进入休眠状态，结束充电。采用上述充电方法后，汽车钥匙处于OFF档状态时，将对动力电池进行智能充电，从而防止出现因动力电池馈电而导致车辆无法启动的问题。
