The invention provides a fuel cell vehicle multi-energy hybrid power control method, device and system. When determining that the current running state of the whole vehicle is that the vehicle entersthe station or decelerates, preferably, the super capacitor feeds back braking energy, the fuel cell provides vehicle power output; when a vehicle enters a station or decelerates, the whole vehicle isin a braking energy feedback state; preferably, the super capacitor is charged, when the charging of the super capacitor reaches a threshold value, the power battery is charged, and the charging anddischarging times of the power battery are reduced by preferably charging the super capacitor, so that the service life of the power battery of the fuel battery and power battery hybrid electric vehicle is prolonged, and the cost of the fuel battery and power battery hybrid electric vehicle is reduced.
本申请提供的一种燃料电池车多能源混合动力控制方法、装置及系统,在确定当前整车运行状态为车辆进站或减速时,优先由超级电容回馈制动能量,并由燃料电池提供整车功率输出,即:当车辆进站或减速时,整车处于制动能量回馈状态,优选为超级电容充电,在超级电容充电达到阈值时,再给动力电池进行充电,通过优选给超级电容充电,来减少动力电池的充放电次数,从而提高燃料电池和动力电池混合动力车的动力电池使用寿命,进而降低燃料电池和动力电池混合动力车的成本。
