锂离子动力电池热管理系统的研究

Research on thermal management system of lithium ion power battery

目前电动汽车上应用最广泛的电化学动力源是锂离子动力电池,因为其具有高比能量、长循环寿命等显著的优点。然而,电池本身的温度变化会对电池的安全性、性能、寿命等造成较大的影响。所以,本文重点介绍,在特定的环境下,研究电池温度变化的特性,并且通过电池温度合理有效的控制,利用关键技术分析,其本身就具有重要的现实意义。

At present,the most widely used electrochemical power source in electric vehicles is lithium ion power battery,because of its high specific energy,long cycle life and other significant advantages.However,the temperature change of the battery itself will have a great impact on the safety,performance and life of the battery.Therefore,this paper mainly introduces that it is of great practical significance to study the characteristics of battery temperature change in a specific environment,and to make reasonable and effective control of battery temperature and use key technologies for analysis.
