电动汽车动力锂离子电池可靠性关键技术综述
Overview of Key Reliability Technologies for Power Lithium-ion Batteries Used in Electric Vehicles
摘要
Abstract
As power lithium-ion batteries play a key role in the electric vehicle industry,ensuring their working re-liability has become a research hotspot at present.In this paper,the materials and manufacturing processes of lithium-ion batteries are reviewed.The battery state estimation and remaining useful life prediction methods are summarized in detail,and the advantages and disadvantages of these methods are discussed.From the perspective of battery manage-ment system,the relevant knowledges of equalization management system and thermal management system are sorted out in turn.From the perspective of electric vehicle hybrid energy storage system,the performance degradation mechanism under actual working conditions and the relevant technologies are elaborated upon.Finally,the status quo of key tech-nologies related to the reliability of power lithium-ion batteries used in electric vehicles is summarized from four aspects,and the development possibilities in the future are forecasted.关键词
