Research on the Modularization of the Auxiliary Power Supply System of the High-Speed Train

The auxiliary power supply system is an important part of the high-speed train, which provides a comfortable environment for passengers and ensures the safe operation of trains. Based on the modularization technology in the design of the auxiliary power supply system, we consider the product demand as input condition, consider the key parameters of the auxiliary power supply system as an output, and standardize the mapping rules and configuration rules of each module of the auxiliary power supply. In the case of CRH2A, based on the modularization technology, we design the key parameters such as the auxiliary power unit (APU) capacity and the battery capacity, which indicate that the use of modular technology can quickly design customized and personalized products to meet customer demand.
