电池热效应分析

Thermal performance analysis of batteries

电池在充放电过程中由于内阻等方面影响会产生热量,而电池在高温下循环会严重影响电池整体的性能与寿命。基于国内外实验和理论分析,概述了几种电池热效应模型。对其内部多种发热效应进行了总结。并计算了产热量,得到了放电过程中的产热值及电池温度场分布,为将来进行电池温升效应研究及散热措施提供了依据。

Heat was produced during the charge process as a result of the internal resistance and so on.However,the performance and cycle life would be seriously affected in a high temperature.Thermal models were generally introduced in this paper base on the experiments and theories,and the thermal performance of the batteries was investigated.After calculation,the sum of heat and the temperature distribution was obtained,which provided a basis for the research of future temperature rising effect and heat dissipation.
