According to the energy management method of the battery, after the starting mode is determined to be the low-temperature cold starting mode, the request power of the vehicle is obtained, the actual output power of the fuel battery is determined, and the current energy management requirement can be determined by comparing the actual output power with the request power; then, according to the request power and the actual output power, determining recovery power or compensation power corresponding to the energy management requirement, and ensuring that the power battery is not overcharged by recovering the recovery power in the actual output power, so that the actual output power is compensated by the compensation power; the problem of insufficient power output of the vehicle is solved, so that the fuel cell can be smoothly started, and the problems that the electric quantity of the power cell is continuously reduced and even the vehicle is directly powered off are avoided.
本申请提供一种电池的能量管理方法,在确定启动模式为低温冷启动模式后,获取车辆的请求功率并确定燃料电池的实际输出功率,可以通过比较实际输出功率和请求功率来确定当前的能量管理需求,然后根据请求功率和实际输出功率确定能量管理需求所对应回收功率或补偿功率,通过回收实际输出功率中的回收功率来保证动力电池不会出现过度充电的危险,以补偿功率过对实际输出功率进行补偿,解决了车辆动力输出不足的问题,进而保证了燃料电池可以顺利的启动,避免了动力电池电量持续下降甚至车辆直接下电的问题。
