The invention discloses an energy management control method for an electricity-electricity hybrid fuel cell vehicle. When the vehicle meets the condition of opening the fuel cell system; the vehicle control unit comprehensively calculates the current required power of the fuel cell system according to the residual electric quantity SOC of the power battery, the current driving intention of the driver, the accessory electric appliance power requirement and the like; a weight ratio is calculated according to the dynamic scale factor K, a currently permitted minimum power value Pr1 is obtained through comparison, then dividing the operating power of the fuel cell system into six fixed-point power operating points, and the fixed-point required power of the fuel cell system is determined through a fixed-point interpolation query mode when set power filtering time t1 is reached; and when the power of the fuel cell system reaches the required power, the next required power is updated after the filtering time t2 for continuous operation of the power is set. The power of the fuel cell system can stably change along with the whole vehicle power trend, and the risk that the service life of the fuel cell system is shortened due to frequent change of the fuel cell power is effectively avoided.
本发明公开的是一种电电混合燃料电池汽车能量管理控制方法,在整车满足燃料电池系统开堆条件下,整车控制器根据动力电池剩余电量SOC、当前司机驾驶意图、附件电器功率需求等综合计算燃料电池系统当前的需求功率,由动态比例因子K计算权重比,并通过对比获取当前许可的最小功率值Pr1,然后将燃料电池系统运行功率划分为六个定点功率运行点,在达到设定功率滤波时间t1时,通过定点插值查询方式确定燃料电池系统定点需求功率;燃料电池系统功率达到需求功率时,设定功率持续运行的滤波时间t2后更新下一个需求功率。本发明可以满足燃料电池系统功率能够稳定跟随整车功率趋势变化,有效避免燃料电池功率频繁变化导致燃料电池系统寿命降低的风险。
