摘要: 作为新型储能器件的代表,锂离子电池因其优异的性能表现与环保特性得到广泛应用。然而,无论是低速充电导致的漫长充电时间,还是快速充电导致的电池退化仍然是阻碍锂离子电池进一步推广与发展的关键问题。鉴于此,对锂离子电池的快速充电策略进行设计成了近年的一个研究热点。为了总结研究进展,从快速充电策略设计的核心内容充电问题描述、电池模型建立、充电方法设计三个方面对现有的研究进行了系统的综述。首先,介绍快速充电策略设计的研究背景,调查充电问题的优化目标、约束条件、设计变量的设置方式;然后,简述锂离子电池的内部机理与几种常用的电池模型,并归纳融合机器学习的建模方法;接着,重点分析现有的不同充电方法,并根据方法特点进行分类与讨论;最后,基于研究现状总结未来的可能研究方向,希望为学者提供研究思路以设计更高效、更易应用的快速充电策略。

Abstract: As a representative of innovative energy storage devices, lithium-ion batteries have been widely used due to their excellent performance and environmentally friendly properties. However, the long charging time caused by slow charging and the degradation caused by fast charging remain critical issues that hinder the further promotion and development of lithium-ion batteries. To this end, the design of the fast charging strategies of lithium-ion batteries has become a hot research topic recently. To summarize the research progress, a systematic review of current research on this topic is presented from three aspects: formulation of the charging problem, establishment of battery models, and design of charging methods, all core elements in the fast charging strategy design. First, the research background of the fast charging strategy design is introduced. Specifically, how to set the optimization objectives, constraints, and design variables of the design problem is investigated. Second, the internal mechanisms of lithium-ion batteries and some commonly used battery models are briefly described, and the modeling methods that incorporate machine learning are also summarized. Additionally, various existing charging methods are especially analyzed and classified based on their characteristics. Moreover, based on the current research status, some future directions are given, aiming to offer researchers a valuable opportunity to design more efficient and user-friendly fast charging strategies.
