The invention discloses a vehicle energy management method, device and equipment and a storage medium, and belongs to the technical field of hydrogen fuel automobiles. When the hydrogen fuel cell charges the high-voltage power cell, the actual output power of the hydrogen fuel cell and the energy recovery power of the whole vehicle are obtained; determining the actual recharging power according to the actual output power of the hydrogen fuel cell and the energy recovery power of the whole vehicle; when the actual recharging power is greater than or equal to a first recharging power threshold value of the high-voltage power battery and less than or equal to a second recharging power threshold value of the high-voltage power battery, recording a first continuous charging duration; the actual output power of the hydrogen fuel cell is adjusted according to the actual recharging power, the first recharging power threshold value and the first continuous charging duration, it is ensured that the vehicle system power is within the allowable recovery range of the power battery pack in the mode, the battery pack is not polarized, the power battery pack is protected, and the service life of the vehicle is prolonged. And the problem that redundant power cannot be discharged is avoided.

    本发明公开了一种车辆能量管理方法、装置、设备及存储介质,属于氢燃料汽车技术领域。本发明通过在氢燃料电池对高压动力电池进行充电时,获取氢燃料电池的实际输出功率和整车的能量回收功率;根据氢燃料电池的实际输出功率和整车的能量回收功率确定实际回充功率;在实际回充功率大于等于高压动力电池的第一回充功率阈值且小于等于高压动力电池的第二回充功率阈值时,记录第一持续充电时长;根据实际回充功率、第一回充功率阈值以及第一持续充电时长对氢燃料电池的实际输出功率进行调整,通过上述方式确保车辆系统功率在动力电池包允许回收范围内,使得电池包不出现极化现象,保护了动力电池包,避免产生多余功率无法泄放的问题。
