The embodiment of the invention discloses a multi-power-source engineering machinery energy management system, a method, a device and a storage medium. A second energy management unit in the system is used for controlling a first power storage battery system and a second power storage battery system to alternately supply power to a load; and a first energy management unit is used for controlling the range extender to charge the first power storage battery system or the second power storage battery system when the first power storage battery system or the second power storage battery system is idle. The independent power storage battery system is adopted to alternately supply power to the load, the range extender charges the power storage battery system when the power storage battery system is idle, the frequency of frequent charging and discharging of the power storage battery system is reduced, the service life of the power storage battery system is prolonged, the range extender does not directly supply power to the load, the range extender can stably work in an efficient energy-saving area, the working efficiency of the range extender is improved, and energy consumption is reduced.

    本申请实施例公开了一种多动力源工程机械能量管理系统、方法、装置和存储介质,该系统中的第二能量管理单元用于控制第一动力蓄电池系统和第二动力蓄电池系统交替为负载供电;第一能量管理单元用于控制增程器在第一动力蓄电池系统或第二动力蓄电池系统空闲时为第一动力蓄电池系统或第二动力蓄电池系统充电。本申请实施例采用独立的动力蓄电池系统交替对负载进行供电,增程器在动力蓄电池系统空闲时对其充电,减少了动力蓄电池系统频繁充放电的次数,延长了动力蓄电池系统的使用寿命,增程器不直接为负载供电,可使增程器稳定工作于高效节能区,提高了增程器的工作效率,降低了能耗。
