车用锂离子电池加热系统研究进展

Research progress of automotive lithium-ion battery heating system

锂离子与其他二次电池相比具有比能量高、自放电率低等优点,适用于电动汽车(EV)和混合动力汽车(HEV)。锂离子电池低温下性能较差,使用受到限制。通过对国内外锂电池组热管理技术研究进展回顾,重点总结了已被采用的热管理技术特点。

Compared with other secondary batteries, lithium ion has the advantages of high specific energy and low self-discharge rate, and is suitable for electric vehicles (EV) and hybrid electric vehicles (HEV). Lithium-ion batteries had poor performance at low temperatures and their use was limited. Through reviewing the research progress of thermal management technology of lithium battery packs at home and abroad, the adopted characteristics of thermal management technologies were summarized.
