Feasibility Study on Safety Protection Technology of Lithium Titanate Battery for Urban Rail Transit Vehicles

Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 5

Abstract

Objective Safety issues such as short circuit, thermal runaway, and resulting explosion of lithium-ion batteries have become one of the bottlenecks for the application and development in urban rail transit vehicles. Therefore, the urban rail transit industry urgently needs to research the safety protection technology for lithium titanate batteries to ensure the normal operation and safety of urban rail transit. Method Through analysis of battery cell design selection, module design and verification, battery management system design, charge and discharge management, fault management, system testing and verification, battery pack simulation design, experimental verification, and implementation of other physical protection measures, the feasibility of safety protection of lithium titanate batteries in urban rail transit is validated. Result & Conclusion By implementing various protective measures, the safety risks of short circuit, thermal runaway, and explosions of lithium titanate batteries can be reduced to a controllable range, thereby ensuring the safe application of lithium titanate batteries as a backup and temporary power supply system in urban rail transit vehicles.
