The invention discloses an intelligent electricity supplementing system for new energy automobile storage battery power shortage, which comprises a high-voltage battery, a vehicle control unit and a storage battery which are electrically connected, and further comprises an external voltage measuring device used for measuring the voltage of the storage battery, and the external voltage measuring device is electrically connected with the vehicle control unit; when the external voltage measuring device measures that the current voltage of the storage battery is lower than a set threshold value, triggering warning information is sent to the vehicle control unit; and the vehicle control unit controls the high-voltage battery to charge the storage battery to a preset voltage value according to the trigger warning information. The current voltage of the storage battery is monitored in real time through the external voltage measuring device, the electric energy of the whole vehicle does not need to be consumed, and therefore extra power shortage of the storage battery cannot be caused; as long as the current voltage of the storage battery is monitored to be lower than the set threshold value, the vehicle is awakened and the high-voltage battery is controlled to charge the storage battery, so that travel troubles caused by power shortage of the storage battery are prevented.

    本发明公开了一种新能源汽车蓄电池亏电时的智能补电系统,包括电性连接的高压电池、整车控制器、和蓄电池,还包括用于测量蓄电池电压的外接测压装置,所述外接测压装置与所述整车控制器电性连接;当所述外接测压装置测得所述蓄电池当前电压低于设定阈值时,即向所述整车控制器发出触发警示信息;所述整车控制器根据所述触发警示信息控制所述高压电池为所述蓄电池充电至预定电压值。本发明通过外接测压装置实时监测蓄电池的当前电压,而无需消耗整车电能,因此不会造成蓄电池的额外亏电;只要监测到的蓄电池当前电压低于设定阈值,即唤醒车辆并控制高压电池为蓄电池充电,以此防止蓄电池亏电造成出行困扰。
