The invention relates to the technical field of vehicles, in particular to a braking energy recovery method and device, a fuel cell vehicle and a storage medium, and the method comprises the steps that the current allowable recovery power of a power battery of the fuel cell vehicle during braking energy recovery is obtained; the output power of a fuel cell of the fuel cell vehicle is reduced to preset power, and the target recovery power of the braking energy is calculated according to the current allowable recovery power and the preset power; and the current power of the energy recovery motor is increased to the target recovery power, and braking energy recovery is conducted according to the target recovery power. Therefore, the problems that in the prior art, the battery recovery power is determined by the output power of the fuel battery and the recovery power of the braking energy, the high output power of the fuel battery reduces the recovery power of the braking energy when the vehicle is braked, and the fuel battery keeps working normally are solved. The brake energy recovery effect is poor; the brake energy is wasted, and the like.

    本申请涉及车辆技术领域,特别涉及一种制动能量回收方法、装置、燃料电池车辆及存储介质,其中,方法包括:获取燃料电池车辆在制动能量回收时动力电池的当前允许回收功率;降低燃料电池车辆的燃料电池的输出功率至预设功率,并根据当前允许回收功率和预设功率计算制动能量的目标回收功率;增加能量回收电机的当前功率至目标回收功率,并按照目标回收功率进行制动能量回收。由此,解决了现有技术中电池回收功率由收燃料电池的输出功率和制动能量的回收功率决定,车辆制动时燃料电池的高输出功率会使得制动能量回收功率降低,且燃料电池保持正常工作,导致制动能量回收效果较差和制动能量的浪费等问题。
