The invention provides a power supply duration-based power supply method and system for a hydrogen fuel cell stack and a hydrogen fuel electric vehicle. A control chip acquires the current power of a load end according to the current and voltage of the load end, and then acquires the current residual amount of hydrogen in a hydrogen storage device according to the total power which can be provided by the hydrogen storage device. The residual amount of hydrogen can be obtained at any time without other detection means or other external components, and use and replacement are convenient. A charging circuit is effectively controlled through the control chip, so that the charging mode of the hydrogen fuel cell stack on a lithium battery is changed, the effective utilization rate of hydrogen is improved, the service time of the hydrogen is longer, and the stroke of the hydrogen fuel electric vehicle is prolonged.

    本发明提供了一种基于供电时长的氢燃料电池电堆的供电方法、系统及氢燃料电动车,控制芯片根据负载端的电流和电压,从而获取所述负载端的当前功率,再依据储氢装置可提供的总功率,获取当前储氢装置内的氢气剩余量,无须其他检测手段,也无须其他外部组件,即可随时获知氢气剩余量,方便使用和替换。且通过控制芯片对充电电路进行有效控制,从而改变氢燃料电池电堆对锂电池的充电模式,提高氢气有效使用率,使得氢气的使用时间更长,加长氢燃料电动车的行程。
