The invention discloses a fuel cell whole vehicle energy management method. An intelligent driving system, a fuel cell whole vehicle VCU, a battery management system BMS, a fuel cell controller and a fuel system are included. The method has the beneficial effects that the fuel cell constantly changes along with the required power of the whole vehicle according to the power output capacity of the fuel cell, the required power of the whole vehicle is predicted and adjusted in time in combination with the map preset in the intelligent driving system, the dynamic property of the whole vehicle is guaranteed, meanwhile, it is guaranteed that the fuel cell works in the optimal working area, and the service life of the fuel cell is prolonged. The problem that required power calculation meets actual requirements when the fuel cell carries out power following calculation is solved, and the contradiction between energy management power limitation and the whole vehicle power requirement is solved; based on a fuzzy energy management strategy and a global optimization strategy, the overload problem of the fuel cell is reduced, and the dynamic property of the automobile and the efficiency of the fuel cell are kept in the optimal state in the whole process.
本发明公开了一种燃料电池整车能量管理方法,包括智驾系统、燃料电池整车VCU、电池管理系统BMS、燃料电池控制器、燃料系统;本发明的有益效果是:燃料电池按照自身功率输出能力,时刻跟随整车需求功率变化,同时结合预置在智驾系统的地图,进行整车需求功率预测,及时调整整车需求功率,保证整车动力性的同时保证燃料电池工作在最佳工作区,解决燃料电池进行功率跟随计算的时候需求功率计算符合实际要求,解决能量管理功率限制和整车动力性需求之间的矛盾;基于模糊型能量管理策略、全局优化策略,降低了燃料电池的过载问题,使全过程汽车动力性、燃料电池效率保持最优状态。
