A Self-traction Scheme for Exported Urban EMUs

In response to the self-traction requirements of an exported urban Electric Multiple Unit (EMU), this paper conducts calculations on the self-traction characteristics of EMU and a comprehensive comparison and selection of different types of batteries, considering factors such as energy density, cycle life, and safety performance. It proposes a detailed self-traction circuit scheme with optimized topological structure and supporting control strategies involving energy management and fault protection mechanisms, and finally forms a complete and practical self-traction solution. This solution not only meets the technical specifications of this project but also provides valuable reference for the subsequent promotion and application of self-traction technology in urban EMUs, laying a foundation for improving operational flexibility and emergency response capabilities.
