The invention provides a fuel cell vehicle and a whole vehicle energy control system thereof, which comprises the following steps: after a power-on signal sent by a power distribution assembly is obtained, sending starting power to a high-power fuel cell engine; after a starting success signal fed back by the high-power fuel cell engine is received, idle speed power is sent to the high-power fuel cell engine; when it is judged that the current vehicle speed reaches or exceeds the preset target value, the target power, fed back by the power battery, of the first control period is sent to the high-power fuel cell engine with the preset control period as the unit, integral calculation is conducted on the whole vehicle average power in the current control period, and the set power of the next control period is generated; and when it is judged that the current vehicle speed is smaller than the preset target value and continues to be smaller than the preset detection time, idle speed power is sent to the high-power fuel cell engine. In addition, an existing whole vehicle energy control scheme has the problems of short service life of a power battery, overhigh temperature and poor whole vehicle performance.

    本发明提供了一种燃料电池汽车及其整车能量控制系统,包括:在获取到配电组件发送的上电信号后,发送启动功率给大功率燃料电池发动机;在接收到大功率燃料电池发动机反馈的启动成功信号后,发送怠速功率给大功率燃料电池发动机;当判断到当前车速达到或超过预设目标值时,以预设控制周期为单位,发送动力电池反馈的第一个控制周期的目标功率给大功率燃料电池发动机,对当前控制周期内的整车平均功率进行积分计算,生成下一个控制周期设定功率;当判断到当前车速小于预设目标值,且持续小于预设检测时间时,发送怠速功率给大功率燃料电池发动机。此外,现有整车能量控制方案存在动力电池寿命短、温度过高,整车性能差的问题。
