According to the fuel cell output power control method provided by the embodiment of the invention, the running power of the energy storage device, the whole vehicle demand power and the safety voltage minimum output power are obtained, if the safety voltage minimum output power is greater than or equal to the whole vehicle demand power, the idle state is determined, and the current energy storage state and the residual electric quantity of the power cell are monitored; if the energy storage is in a saturated state and the residual electric quantity of the power battery is greater than or equal to an electric quantity control threshold value, improving the power of the energy storage device and determining the energy storage increment power, and when the sum of the energy storage increment power, the operation power of the energy storage device and the required power of the whole vehicle is greater than or equal to the minimum output power of the safety voltage, determining the sum as the output power of the fuel battery; according to the method, the power of the energy storage device is adjusted according to the energy storage state when the vehicle is in the idling state, redundant power is stored or counteracted to determine the output power of the fuel cell, it is guaranteed that the output of the fuel cell in the idling state is consistent with consumption of the energy storage device, and the power output of the whole vehicle is zero.

    本发明实施例中的燃料电池输出功率控制方法,通过获取储能装置运行功率、整车需求功率和安全电压最小输出功率,若安全电压最小输出功率大于或等于整车需求功率,则确定为怠速状态,并监听当前储能状态和动力电池剩余电量,若储能饱和状态,且动力电池剩余电量大于或等于电量控制阈值,提高储能装置功率并确定储能增量功率,当储能增量功率、储能装置运行功率和整车需求功率的功率之和大于或等于安全电压最小输出功率,将其确定为燃料电池输出功率;本方法在车辆怠速状态时根据储能状态调节储能装置功率,对冗余功率进行存储或抵消,以确定燃料电池输出功率,保证燃料电池在怠速状态下输出与储能装置的消耗一致,实现整车功率输出为零。
