The invention provides an electric engineering machine multi-mode power supply system and an electric engineering machine thereof. The electric engineering machine multi-mode power supply system comprises a vehicle control unit, a high-voltage management unit, a power distribution cabinet, a power battery power supply assembly, a diesel engine, a range extender assembly, a transfer case assembly and a multi-actuator hydraulic assembly. The subsystems of the whole system are communicated through a CAN bus, and power input and power output of the control system are carried out through the whole vehicle control unit. Through the related functions of the system, the output current of the multi-mode power supply system can be maintained at a healthy and stable optimal value when the electrically-driven engineering machinery works in a dramatic load working condition, meanwhile, the cruising ability of the electrically-driven engineering machinery can be improved, and the stability of power output of a power system is effectively guaranteed.

    本发明提供了一种电动工程机械多模式供电系统及其电动工程机械,包括:整车控制器、高压管理单元、配电柜、动力电池供电组件、柴油机、增程器组件、分动箱组件、以及多执行器液压组件。整个系统的各个子系统通过CAN总线进行通讯,由整车控制单元进行控制系统的动力输入及动力输出。通过本系统的相关功能,可以使得电驱动工程机械工作在剧变负载工况时多模式供电系统的输出电流维持在一个健康、平稳的最优值,同时可以提高了电驱动工程机械的续航能力和有效保证了动力系统的动力输出的稳定性。
