聚合物锂离子电池温升及散热特性研究

Research of temperature rising and heat dissipation of lithium-ion polymer battery

对聚合物锂离子电池组在大功率输出过程中,由于内阻功耗引起的温升特性建立最大温升和最小温升模型,并对叠片式散热建立数学模型并进行了数值计算。通过分析研究得知,电池组的温升效应明显,采用适当散热布置时,电池内部的温升效应可以得到有效抑制。

In the paper,the research of temperature rising caused by power dissipation of lithium-ion polymer battery was made in the process of high-power output,which included the theoretical analysis of its temperature rising of maximum and minimum value and numerical computation under some conditions.The numerical and theoretical re-sults show that the temperature rising caused by power dissipation can be controlled when the fin construction is properly arranged.
