The invention aims to disclose a direct-current power generation and power supply management system for engineering vehicles. The direct-current power generation and power supply management system comprises an engine controller ECU, a generator, a generator controller GCU, a power motor, a motor controller MCU, a power distribution unit PDU and a power control unit PCU. Compared with the prior art, the power control unit PCU is used for coordinating and managing energy of an engine, the generator and a power utilization system (each motors and motor controllers MCU) through CAN communication and the power distribution unit PDU according to requirements of a vehicle controller VCU, and ensuring of stable and efficient operation of a vehicle power grid; the generator controller GCU is used for controlling generator current parameters and maintains bus voltage stability; series power supply work of the system can be realized through scientific power utilization and power generation management of the power utilization system and rapid and stable response of the power generation system, rapid response of power utilization loads is realized within 3 seconds, and the purpose of the invention is realized.

    本发明的目的在于公开一种工程车辆用直流发电与电源管理系统,它包括发动机控制器ECU、发电机、发电机控制器GCU、动力电机、电机控制器MCU、动力分配单元PDU和动力控制单元PCU;与现有技术相比,动力控制单元PCU负责根据车辆控制器VCU的要求,通过CAN通讯和动力分配单元PDU对发动机、发电机、用电系统(各电动机以及电机控制器MCU)的能量协调与管理,并确保车辆电网的稳定高效运行;发电机控制器GCU控制发电机电流参数,维持母线电压稳定;通过对用电系统的科学用电和发电管理,以及发电系统的快速稳定响应,即可实现系统的串联供电工作,在3秒之内实现用电负荷的快速相应,实现本发明的目的。
