The invention discloses a fuel cell vehicle hydrogen leakage detection method, device and equipment and a medium, and belongs to the technical field of fuel cell vehicles. The method comprises the steps that when a vehicle stops and flames out and the whole vehicle is powered off, a hydrogen leakage detection system is awakened to conduct hydrogen leakage routing inspection once every set time interval; during the hydrogen leakage inspection period of the hydrogen leakage detection system, a first voltage value of a storage battery and a second voltage value of a high-voltage battery are obtained in real time, and the storage battery is used for supplying power to the hydrogen leakage detection system; and determining whether to control the high-voltage battery to charge the storage battery or not according to the first voltage value and the second voltage value. According to the method, the hydrogen leakage detection system can continuously and normally work for a longer time in the parking period, and the situation that the vehicle cannot be normally started due to the fact that the electric quantity of the storage battery is insufficient is prevented.

    本发明公开了一种燃料电池车氢泄漏检测方法、装置、设备及介质,属于燃料电池汽车技术领域。该方法包括:当车辆停车熄火且整车下电时,每间隔设定时间唤醒氢泄漏检测系统进行一次氢泄漏巡检;在所述氢泄漏检测系统进行氢泄漏巡检期间,实时获取蓄电池的第一电压值和高压电池的第二电压值,所述蓄电池用于为所述氢泄漏检测系统供电;根据所述第一电压值和所述第二电压值,确定是否控制所述高压电池为所述蓄电池充电。该方法能够使得氢泄漏检测系统在停车期间可以更长时间的持续正常工作,并防止因蓄电池电量不足,导致车辆无法正常启动的情况发生。
