摘要
城市轨道交通作为城市中旅客运输的主要载体,其安全一直是人们关注的焦点。文章设计了一款轨道交通车载储能系统,利用钛酸锂电池的储能特性及高倍率充放电特性,实现了车辆在离网故障下的应急自牵引及辅助系统的紧急供电,同时满足车辆制动能量的回收需求。
As the main carrier of passenger transport in the city,the safety of urban rail transit has been the focus of atention.In this paper,an on-board energy storage system for Rail Transit vehicles is designed,which makes use of the energy storage characteristics of Lithium titanate batteries and the high-rate charge-discharge characteristics to realize the emergency power supply of the emergency self-traction and auxiliary system of the vehicle under the off-grid fault,at the same time to meet the vehicle braking energy recovery needs.
