The embodiment of the invention provides an energy control method and device for a fuel cell vehicle, electronic equipment and a readable medium, and the method comprises the steps: obtaining the high-efficiency point power of a fuel cell, searching a corresponding lithium battery SOC interval when the fuel cell can be operated at the high-efficiency point power according to the high-efficiency point power, and if the SOC of the lithium battery is in the SOC interval, executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step of executing the step; controlling the fuel cell to take high-efficiency point power as power output, if the SOC of the lithium battery is lower than the minimum value of the SOC interval, increasing the power of the fuel cell and detecting the SOC of the next time period according to a preset time interval, if the SOC of the next time period is lower than the SOC of the previous time period, continuing to increase the power of the fuel cell, and if the SOC of the next time period is lower than the SOC of the previous time period, continuing to increase the power of the fuel cell; and if the difference value between the SOC of the next time period and the minimum value of the SOC interval is greater than the preset SOC value, re-controlling the fuel cell to take the high-efficiency point power as power output. By adopting the method disclosed by the invention, the fuel cell can work at a high-efficiency power point for most time, and the hydrogen loss of the fuel cell vehicle can be obviously reduced.

    本发明实施例提供了一种燃料电池车的能量控制方法、装置、电子设备及可读介质,所述方法包括:通过获取燃料电池的高效率点功率,根据高效率点功率查找燃料电池可处于高效率点功率运行时对应的锂电池SOC区间,若锂电池的SOC处于SOC区间,控制燃料电池以高效率点功率作为功率输出,若锂电池的SOC低于SOC区间的最小值,增大燃料电池的功率并按照预设时间间隔检测下一个时段的SOC,若下一个时段的SOC小于前一个时段的SOC,则继续增大燃料电池的功率,若下一个时段的SOC与SOC区间的最小值的差值大于预设SOC值,则重新控制燃料电池以高效率点功率作为功率输出。采用本发明该方法,能使燃料电池大部分时间都工作在高效率功率点,能明显减少燃料电池车的氢气损耗。
