摘要
电池管理系统是锂离子电池高效、安全运行的重要保障。电池的状态估计在电池管理系统中发挥着重要的作用。健康状态是锂离子电池状态估计的重要指标之一。通过对近几年国内外锂离子健康状态估计方法相关文献的整理,综述了锂离子电池健康状态的定义和估计方法,并对现有的估计方法进行了分类和阐述。最后针对现有估计方法的不足,提出未来需要改进的方向。
Battery management system is an important guarantee for the efficient and safe operation of lithium-ion batteries,in which the battery state estimation plays an important role.The state-of-health(SOH)is one of the important indicators for the state estimation of lithium-ion batteries.In this paper,the definition and estimation methods for the SOH of lithium-ion batteries are reviewed through the summary of related literatures in recent years,and the existing estimation methods are classified and described.Finally,aimed at the shortcomings of the existing estimation methods,the direction of improvement in the future is put forward.
