摘要
电动汽车的普及对动力电池相关的技术提出了更高的要求,使电池保持在合适温度区间工作的动力电池热管理系统已经成为各大厂商的核心技术需求.由于锂离子电池在冬季低温环境下性能下降、寿命衰减尤为明显,低温热管理技术更是近年来动力电池研究的重点.从锂离子电池在低温环境中的性能劣化机理出发,对低温热管理系统的发展现状进行了综述,并结合最新研究进展,归纳了一套电动汽车低温热管理评价方法.
Abstract
The widespread adoption of electric vehicles has raised higher demands for the technology related to power batteries.Consequently,a thermal management system that keeps the battery within an optimal temperature range has become a core technical requirement for major manufacturers.In recent years,the focus has shifted towards low-temperature thermal management technology,driven by the performance degradation and life decay of lithium-ion batteries in winter's cold conditions.Based on the degradation mechanism of lithium-ion batteries in cold conditions,the paper provides a comprehensive overview of the development status of low-temperature thermal management systems.Additionally,in conjunction with the latest research progress,it summarizes a set of evaluation methods for low-temperature thermal management of electric vehicles.
