锂电池在地铁改造工程中的应用分析

Analysis on Lithium Batteries Application in Existing Line Reconstruction for Urban Rail Transit

铅酸蓄电池设备体积及重量较大,当机房环境较差时,蓄电池工作寿命受到影响,设备故障率增高,存在有热失控风险。锂电池具有体积小巧、重量轻的明显优势,耐高温能力较为突出,充放电循环性能优异,充电快,更为环保。分析不同种类锂电池的特性,与主流铅酸蓄电池性能进行对比,结合地铁工程特性提出锂电池在地铁改造工程中的应用建议。

The volume and weight of lead-acid battery equipment is large.When the environment of the computer room is poor,the operating life of the battery will be aff ected,the equipment failure rate increases,and there is a risk of thermal runaway.Lithium battery has the obvious advantages of small size,light weight,high temperature resistance,excellent charge-discharge cycle performance,fast charging,more environmental friendly and so on.Therefore,this paper analyzes the characteristics of diff erent types of lithium batteries and compares them with the performance of mainstream lead-acid batteries.Combined with the characteristics of rail transit,the application suggestions of lithium batteries in the reconstruction of existing lines of urban rail transit are put forward.
