摘要:

准确估计锂离子电池荷电状态(state of charge, SOC)、电池健康度(state of health,SOH)以及预测电池剩余寿命(remaining useful life,RUL)是电池管理的重要内容,对延长电池寿命和保证电池系统可靠性具有重要意义。各国研究人员对电池状态评估与寿命预测方法进行了大量研究,提出了多种方法。首先,介绍了SOC与SOH的定义及已有估算方法,并进行了对比;然后,介绍了RUL的定义,并对主要方法进行了分类与比较;最后,总结了锂离子电池状态估计与寿命预测方面存在的挑战,并提出了未来的发展方向。

Abstract:

Accurate estimation of state of charge (SOC), battery state of health (SOH) and prediction of battery remaining useful life (RUL) of lithium-ion battery are important contents of battery management. It is of great significance to prolong battery life and ensure the reliability of battery system. Researchers all over the world have done a lot of research on battery state evaluation and RUL prediction methods, and proposed a variety of methods. This paper first introduced the definition of SOC and SOH and the existing estimation methods and compared them. Then, the definition of RUL was introduced and the main methods were classified and compared. Finally, the challenges of lithium-ion battery state estimation and RUL prediction were summarized, and the future development direction was proposed.

Key words: lithium-ion battery, state of charge (SOC) estimation, state of health (SOH) estimation, remaining useful life (RUL) prediction
