The invention particularly relates to an energy management system of a fuel cell, a vehicle and a method, an acquisition module is used for acquiring a first whole vehicle mass and a first slope value of the vehicle and a first road working condition of a position where the vehicle is located after the vehicle enters a preset continuous driving state; the first drive axle assembly is respectively connected with the second drive axle assembly and the fuel cell system; one end of the super capacitor is connected with the fuel cell engine, and the other end is connected with the second drive axle assembly; and the control module is connected with the first driving assembly and the second driving assembly, and is used for determining an energy distribution strategy of the first driving axle assembly and the second driving axle assembly based on the collected data, controlling the super capacitor to absorb and unload energy, or controlling the first driving axle assembly and the second driving axle assembly to enter a kinetic energy recovery mode. Therefore, the problems that the fuel cell system cannot be quickly unloaded and the energy distribution of the double-electric-drive axle is uneven during emergency braking of the vehicle are solved, the performance of the whole vehicle is improved, and the service life of the fuel cell is prolonged.
本申请特别涉及一种燃料电池的能量管理系统、车辆及方法,其中,采集模块用于在车辆进入预设的持续行驶状态后,采集车辆的第一整车质量、第一坡度值和车辆所处位置的第一道路工况;第一驱动桥总成分别与第二驱动桥总成和燃料电池系统相连;超级电容的一端与燃料电池发动机相连,另一端与第二驱动桥总成相连;控制模块与第一驱动总成和第二驱动总成相连,用于基于采集到的数据确定第一驱动桥总成和第二驱动桥总成的能量分配策略,控制超级电容吸收卸载能量,或者,控制第一驱动桥总成和第二驱动桥总成进入动能回收模式。由此,解决了车辆在紧急制动时燃料电池系统无法快速卸载及双电驱桥能量分布不均等问题,提高了整车性能和燃料电池寿命。
