The invention discloses an energy management method and device of a hydrogen fuel electric vehicle and a storage medium in the technical field of battery control, and aims at solving the problems that in the prior art, the working efficiency of a hydrogen fuel engine is low, and the electric quantity use interval of a power battery cannot be controlled. Comprising the following steps: acquiring residual electric quantity information of a power battery in response to a received mode activation instruction; and whether the remaining electric quantity information is smaller than or equal to a preset threshold value X or not is judged, if yes, a control signal is sent to the hydrogen fuel engine according to a preset control strategy and the collected whole vehicle working parameters, the hydrogen fuel engine is made to generate electricity with the corresponding generation power till the remaining electric quantity information is larger than a preset threshold value Y, and Y is larger than X. According to the invention, the hydrogen fuel engine can be controlled to generate power at corresponding appropriate power, so that the system efficiency of the hydrogen fuel engine is improved to the maximum extent, the electric quantity of the power battery can be maintained in an appropriate use range, and the service life of the power battery can be prolonged.

    本发明公开了一种电池控制技术领域的氢燃料电动车辆的能量管理方法、装置及存储介质,旨在解决现有技术中氢燃料发动机的工作效率较低和未能控制动力电池的电量使用区间的问题。包括响应于接收到的模式激活指令,获取动力电池的剩余电量信息;判断剩余电量信息是否小于等于预设的阈值X,若是则根据预设的控制策略和收集的整车工作参数,向氢燃料发动机发送控制信号,使其以相应的发电功率进行发电,直至剩余电量信息大于预设的阈值Y,其中Y大于X。本发明能够控制氢燃料发动机以相应的合适功率进行发电,从而最大限度提高氢燃料发动机的系统效率,可将动力电池的电量维持在合适的使用区间内,以此可延长动力电池的使用寿命。
