摘要: 随着新能源汽车的广泛使用,动力锂离子电池的热安全性问题日益突出。本文以Bernardi生热机理为基础,耦合不同物理量,分别从电化学-热耦合模型、电-热耦合模型和热滥用模型来介绍单体电池的热特性。由于电池能量密度的增加与行驶工况复杂程度的提高,动力锂离子电池容易发生热量堆积,甚至造成热失控,对此,文中梳理了商用动力电池包的常用冷却方式。最后,根据对影响电池模组安全性的热失控蔓延机理及实测结果,介绍了阻断单体及基本模块热失控传播的有效方法。

Abstract: With the widespread use of new energy vehicles, the thermal safety of power lithiumion batteries has become increasingly prominent. In this paper, based on Bernardi thermogenesis mechanism and coupled with different physical quantities, the thermal characteristics of single battery is introduced from electrochemical-thermal coupling model, electro-thermal coupling model and thermal abuse model respectively. Due to the increase of battery energy density and the increasing complexity of driving conditions, power lithium ion batteries are prone to heat accumulation and even cause thermal runaway. In this regard, this paper summarizes the common cooling methods of commercial power battery packs. Finally, based on the thermal runaway propagation mechanism and the measured results affecting the safety of the battery module, effective methods for blocking the thermal runaway propagation of the monomer and the basic module is introduced.

Key words: lithium ion battery, thermal model, thermal management, thermal safety
