The invention provides an energy management method and system for a fuel cell vehicle. The energy management method and system are applied to a vehicle control unit of the fuel cell vehicle. Comprising the steps that the current temperature of the position where the fuel cell vehicle is located and the lowest environment temperature in a future preset time period are obtained; whether the lowest environment temperature is smaller than or equal to a first temperature threshold value is judged; if yes, executing a winter energy management strategy on a fuel cell of the fuel cell vehicle; and if not, executing a normal-temperature energy management strategy on the fuel cell of the fuel cell vehicle. According to the invention, the technical problem of life attenuation caused by cold start of the fuel cell in a low-temperature environment is relieved.

    本发明提供了一种燃料电池车辆能量管理方法和系统,应用于燃料电池车辆的整车控制器;包括:获取燃料电池车辆所在的位置的当前温度和在未来的预设时间段内的最低环境温度;判断最低环境温度是否小于或等于第一温度阈值;如果是,则对燃料电池车辆的燃料电池执行冬季能量管理策略;如果否,则对燃料电池车辆的燃料电池执行常温能量管理策略。本发明缓解了低温环境下燃料电池冷启动会造成寿命衰减的技术问题。
