The power supply system of centralized power EMU consists of traction power supply system and auxiliary power supply system.Among them,the auxiliary power supply system plays an important role in supplying power to equipment such as air conditioners and sockets on the vehicle to ensure the comfort of travelers.This paper begins with the auxiliary power supply system of CR200J EMU,and discusses the current state of the technology of DC 110 V chargers,AC 380 V three-phase inverters,AC 220 V single-phase inverters and storage batteries,as well as their technical shortcomings.Combined with the latest development concepts such as carbon peak,carbon-neutral,intelligent manufacturing,etc.,the future technological development trend of auxiliary power supply systems is predicted in terms of energy savings,high efficiency,light weight,intelligent BMS,etc.,and the feasibility of the core key technology is analyzed and verified.
