The invention provides a motor train unit auxiliary power supply system and an energy control method. The system comprises a controller and a load power supply module. The load power supply module is connected with the controller and is connected to a high-voltage direct-current bus of a vehicle traction system through a medium-voltage direct-current bus; and the load power supply module obtains electric energy from the high-voltage direct-current bus and stores the electric energy or supplies power to a load under the control of the controller. The auxiliary power supply system of the motor train unit can reliably supply power to the vehicle-mounted equipment under the normal working condition or the working condition that the high-voltage direct-current bus loses power.
本申请提供一种动车组辅助供电系统及能量控制方法,所述系统包括:控制器及负载供电模块;所述负载供电模块连接所述控制器,并通过中压直流母线连接至车辆牵引系统的高压直流母线;所述负载供电模块在所述控制器的控制下从所述高压直流母线获取电能并储存或向负载供电。本申请能够确保动车组辅助供电系统在正常工况或高压直流母线失电工况下,为车载设备进行可靠供电。
