The invention provides an energy management method and system for a hybrid electric drive heavy-load vehicle, and relates to the technical field of heavy-load vehicles, and the method comprises the steps: obtaining the vehicle operation information of the vehicle and the residual charge quantity of a second power source; when the vehicle is in a normal driving state and the vehicle load weight is larger than a first weight threshold value, if the vehicle is in a starting stage, the first power source and the second power source are controlled to be switched to a dual-power-source hybrid power supply mode; if the vehicle is not in the starting stage and the running gradient of the vehicle is larger than zero, the first power source and the second power source are controlled to be switched to a double-power-source hybrid power supply mode, and when the running gradient of the vehicle is smaller than or equal to zero, the power supply modes of the first power source and the second power source are controlled according to the residual charge quantity of the second power source; when the vehicle is in the braking state, the first power source is controlled to stop supplying power, and the second power source is switched to the charging mode. New energy is used, braking energy is recycled, two power sources are dynamically regulated and controlled, and energy conservation and emission reduction are achieved.
本发明提供了一种混合电驱动重载车辆的能量管理方法及系统,涉及重载车辆技术领域,所述方法包括获取车辆的车辆运行信息和第二动力源的剩余电荷量;当车辆状态处于正常行驶状态且车载重量大于第一重量阈值时:若车辆处于起步阶段,控制第一动力源和第二动力源切换至双动力源混动供电模式;若车辆不处于起步阶段,车辆运行坡度大于零时,控制第一动力源和第二动力源切换至双动力源混动供电模式,车辆运行坡度小于等于零时,根据第二动力源的剩余电荷量,控制第一动力源和第二动力源的供电模式;当车辆状态处于制动状态,控制第一动力源暂停供电且第二动力源切换至充电模式。使用新能源,回收制动能量,动态调控两个动力源,实现节能减排。
