The invention provides a power control method and device of a fuel cell, electronic equipment and a vehicle, the power climbing speed of the fuel cell can be determined according to the current working temperature, the determined power climbing speed at the current working temperature can limit a certain range for control, and overload of the fuel cell is avoided; according to the output power and the power climbing speed of the fuel cell, the theoretical output power of the fuel cell at the next moment is determined, and power prediction of the fuel cell is achieved; the request power of the fuel cell is determined according to the current driving mode, the whole vehicle demand power and the theoretical output power, the request power of the fuel cell is determined through the relation between the whole vehicle demand power and the theoretical output power according to different driving modes, and on the premise that the power climbing speed of the fuel cell is allowed, the power climbing speed of the fuel cell is increased. Power control over the fuel cell in different driving modes is achieved, frequent overload operation of the fuel cell is avoided, and the service life of the fuel cell is prolonged.

    本申请提供一种燃料电池的功率控制方法、装置、电子设备及车辆,能够根据当前工作温度确定燃料电池的功率爬升速度,确定当前工作温度下的功率爬升速度可以为控制控制限定一定范围,避免燃料电池超载;然后根据燃料电池的输出功率和功率爬升速度确定燃料电池在下一时刻的理论输出功率,实现燃料电池的功率预测;根据当前驱动模式、整车需求功率和理论输出功率确定燃料电池的请求功率,根据驱动模式的不同,通过整车需求功率和理论输出功率的关系确定燃料电池的请求功率,在燃料电池功率爬升速度允许的前提下,实现不同驱动模式下对燃料电池的功率控制,避免燃料电池频繁进行超载运行,提高了燃料电池的寿命。
