The invention discloses an intelligent charging method and system for a storage battery and a hydrogen fuel cell vehicle. The method comprises the steps: receiving charging request information sent by a T-BOX, wherein the charging request information is used for requesting charging the storage battery; waking up a DCDC based on the charging request information in order wake up a BMS by the DCDC, and waking up the charging of the storage battery through the BMS; enabling the DCDC, and after the DCDC is successfully enabled, controlling a high-voltage power battery to charge the storage battery. In this way, the VCU can control the high-voltage power battery to charge the storage battery, the problem that the hydrogen fuel cell vehicle cannot be normally started due to the fact that the storage battery lacks power when the hydrogen fuel cell vehicle is stalled for a long time can be solved, the problem that the voltage of the storage battery is low after the hydrogen fuel cell vehicle is upgraded can be solved, a BCM state is not needed to trigger charging of the storage battery, and the effect that charging of the storage battery can still be triggered in the state of lack of the BCM can be achieved.

    本申请公开了一种蓄电池的智能补电方法、系统及氢燃料电池汽车,该方法包括:接收T‑BOX发送的补电请求信息,补电请求信息用于请求给蓄电池补电;基于补电请求信息唤醒DCDC,由DCDC唤醒BMS,并通过BMS唤醒给蓄电池补电;使能DCDC,在DCDC使能成功后,控制高压动力电池给蓄电池补电。通过这种方式,VCU可以控制高压动力电池给蓄电池补电,可以解决因氢燃料电池汽车长时间放置时会引起蓄电池馈电,而导致氢燃料电池汽车无法正常启动的问题,可以解决在氢燃料电池汽车升级结束后蓄电池的电压较低的问题,无需BCM状态来触发蓄电池补电,可以达到在缺少BCM的状态下依旧能够触发给蓄电池补电的效果。
