The embodiment of the invention provides a fuel cell power control method when a vehicle is in a high-power demand working condition. The method comprises the following steps: when the vehicle is detected to be in the high-power demand working condition, providing whole vehicle demand power by adopting power cell pulse discharge power and gear fuel cell power within a preset target time; and whenthe actual output power of the power battery is greater than the stable constant-current discharge power of the power battery and the duration time is greater than the target time, controlling the power of the fuel battery to be increased to the target power, wherein the target power is calculated by subtracting the stable constant-current discharge power of the power battery from the actual required power of the whole vehicle, and the sum of the fuel cell power rising time and the preset target time is smaller than or equal to the power cell pulse duration time. According to the embodiment ofthe invention, the long-time high-power requirement of the vehicle can be met, energy can be saved, and the maximization of energy utilization rate and benefit is realized.
本发明实施例提供一种车辆处于大功率需求工况时燃料电池功率控制方法,包括:当检测到车辆处于大功率需求工况时,在预设的目标时间内,采用动力电池脉冲放电功率和挡位燃料电池功率提供整车需求功率;当动力电池实际输出功率大于所述动力电池稳定恒流放电功率,且持续时间大于所述目标时间时,控制燃料电池功率升载至目标功率;其中,所述目标功率通过所述整车实际需求功率减去所述动力电池稳定恒流放电功率计算得到;所述燃料电池功率升载时间和所述预设的目标时间的和小于等于所述动力电池脉冲持续时间。本发明实施例能够满足车辆长时大功率需求,且能够节约能源,实现能源利用率效益的最大化。
