Electric excavator integrated control system and electric excavator system
The invention provides an electric excavator integrated control system and an electric excavator system. The high-voltage input end of the high-voltage power supply management system is electrically connected with the power battery, and the high-voltage output end of the high-voltage power supply management system is electrically connected with the motor controller, the external plug-in working module, the alternating-current vehicle-mounted charging module and the DC/DC conversion module. The motor controller, the vehicle control unit, the external plug-in working module, the alternating current vehicle-mounted charging module, the DC/DC direct current conversion module and the power battery are in communication connection through a CAN bus. All control systems of the electric excavator are integrated into a whole, the space utilization rate is increased, magnetic compatibility design of the whole excavator is facilitated, in addition, part of power electronic components in the integrated control systems are shared in function, part of high-voltage circuit relays, fuses and high-voltage input ports are shared, and the production cost is reduced to a certain degree.
本申请提供了一种电动挖掘机集成控制系统及电动挖掘机系统，高压电源管理系统的高压输入端与动力电池电性连接，高压电源管理系统的高压输出端分别与电机控制器、外接插电工作模块、交流车载充电模块以及DC/DC直流转换模块电性连接；电机控制器、整车控制器、外接插电工作模块、交流车载充电模块、DC/DC直流转换模块及动力电池通过CAN总线通信连接。通过将电动挖掘机的各个控制系统集成为一体，提高了空间利用率，且利于进行整车的磁兼容性设计，另外，集成控制系统内的部分电力电子元器件功能共用，部分高压电路继电器、熔断器、高压输入端口共用，在一定程度上降低了生产成本。
