The invention provides a multi-source composite power supply ground electric vehicle energy management method, a controller and a vehicle. Firstly, load demand power is obtained, and meanwhile, the charge state of each power source is obtained; predicting the target demand power of the vehicle in the target time period according to the load demand power; calculating first output power of the fuel cell according to the target demand power; according to the charge state, the first output power and the current load demand power, determining second output power of the fuel cell, third output power of the lithium battery and fourth output power of the super capacitor; therefore, the power source system is controlled. The output of the fuel cell follows the load change as much as possible according to the current load demand power, meanwhile, the target demand power is predicted, the first output power needing to be output by the fuel cell is calculated, and the following process of the fuel cell is smooth and stable as much as possible according to the first output power, so that the service life of the fuel cell is effectively prolonged; the vehicle cost is reduced.

    本发明提供了一种多源复合供电地面电动车辆能量管理方法、控制器及车辆,首先获取负载需求功率,同时获取各个动力源的荷电状态;然后根据负载需求功率预测目标时段内车辆的目标需求功率;接着根据目标需求功率,计算燃料电池的第一输出功率;再根据荷电状态、第一输出功率和当前的负载需求功率,确定燃料电池的第二输出功率、锂电池的第三输出功率以及超级电容的第四输出功率;从而对动力源系统进行控制。本发明依据当前的负载需求功率使燃料电池的输出尽可能的跟随负载变化,同时预测目标需求功率,计算出燃料电池需要输出的第一输出功率,按照第一输出功率使燃料电池的跟随过程尽量平滑和稳定,从而有效提高燃料电池的寿命,降低车辆成本。
