The invention discloses a fuel cell energy management control method. The fuel cell energy management control method comprises the following steps that the temperature T of a power cell is obtained, if T is less than or equal to a first temperature threshold T1 or T is larger than or equal to a fourth temperature threshold T4, the power cell is controlled not to be allowed continuous charging, andthe fuel cell is controlled not to be started; if T2 is larger than or equal to T and T is larger than T1, the power cell is controlled to be allowed low-power continuous charging, the power P of thefuel cell is controlled to be less than or equal to a first power threshold P1, and SOC of the power cell is less than SOC2; if T4 is larger than T and T is larger than or equal to a third temperature threshold T3, the power cell is controlled to be allowed low-power continuous charging, the power P of the fuel cell is controlled to be less than or equal to a second power threshold P2, and SOC isless than a third SOC threshold SOC3; and if T3 is larger than T and T is larger than T2, the charging power of the power cell is controlled according to the SOC range, and it is controlled that P4 is larger than or equal to P and P is larger than or equal to P3. The situation that the power cell still has continuous high-power charging at high SOC and high and low temperatures is avoided, and itis guaranteed that the power cell has good service life and safety.

    本发明公开了一种燃料电池能量管理控制方法,包括:获取动力电池温度T,若T≤第一温度阈值T1或T≥第四温度阈值T4,控制动力电池不允许持续充电,控制燃料电池不启动;若T2≥T>T1时,控制动力电池允许小功率持续充电,控制燃料电池功率P≤第一功率阈值P1,且动力电池SOC<SOC2;若T4>T≥第三温度阈值T3时,控制动力电池允许小功率持续充电,控制燃料电池功率P≤第二功率阈值P2,且SOC<第三SOC阈值SOC3;若T3>T>T2时,根据SOC范围控制动力电池的充电功率,控制P4≥P≥P3。避免出现动力电池在高SOC和高、低温下仍有持续高功率充电的情况,保证动力电池有良好的使用寿命和安全性。
