The invention provides an energy management method and device for a fuel cell hybrid electric vehicle. The energy management method comprises the steps that the heating required power of a passenger compartment and the current fuel cell temperature are obtained; whether the current fuel cell temperature is greater than a waste heat utilization set threshold value or not is judged; if yes, the actual waste heat power of a fuel cell is calculated; and according to the actual waste heat power and the heating required power, all or part of the heating required power of the passenger compartment isprovided by the actual waste heat power. According to the energy management method, when the passenger compartment has heating required power, the waste heat of the fuel cell is fully utilized to provide heat for the passenger compartment, and the purposes of improving the energy utilization rate and improving the vehicle economy are achieved.

    本发明提供了一种燃料电池混合动力汽车的能量管理方法及装置,包括:获取乘员舱的加热需求功率,以及当前燃料电池温度;判断所述当前燃料电池温度是否大于余热利用设定阈值;若是,则计算燃料电池的实际余热功率;依据所述实际余热功率和所述加热需求功率,将全部或部分所述乘员舱的加热需求功率由所述实际余热功率提供。该能量管理方法综合考虑了在乘员舱有加热需求功率时,充分利用燃料电池余热为其提供热量,达到提高能量利用率和提升车辆经济性的目的。
