The rapid development of lithium-ion battery technology has led to its widespread use in electric vehicles, aerospace, and mobile electronics. Accurate estimation of the state of health of lithium-ion batteries is a challenging task, and previous reviews have had deficiencies in classification, summary, and evaluation of estimation methods. This comprehensive review investigates and discusses 190 relevant studies, providing a thorough analysis of different perspectives on the definition of state of health, representative battery models, commonly used evaluation criteria, and explicit estimation schemes. The review also addresses the main problems and challenges in state of health estimation, proposes future development trends, and summarizes essential public datasets. Overall, this review offers valuable guidance for researchers and engineers working on state of health estimation and promotes further development in this field.
The rapid development of lithium-ion battery (LIB) technology promotes its wide application in electric vehicle (EV), aerospace, and mobile electronic equipment. During application, state of health (SOH) of LIB is crucial to enhance stable and reliable operation of the battery system. However, accurate estimation of SOH is a tough task, especially in its large-scale application. Thus far, a variety of works on the estimation of SOH of LIB have been proposed, along with several review studies that aim to summarize the current research status. However, there are some deficiencies in prior reviews, such as unclear classification, incomplete summary, and insufficient evaluation of estimation methods. Thus, to resolve the shortcomings, the enumeration method is used to fully screen published works related to SOH estimation, and a total of one hundred and ninety relevant studies are investigated for a thorough review and discussion. Besides, the definition of SOH from different perspectives and three representative battery models are summarized, respectively. Meanwhile, twenty commonly used evaluation criteria and two explicit SOH estimation schemes are comprehensively introduced, which all are tabulated in detail for systematic evaluation and fair comparison. Finally, the main problems and challenges in SOH estimation are fully discussed, meanwhile, three promising future development trends are proposed and some essential SOH public datasets are summarized. In general, this review is envisioned to offer insightful guidance to researchers or engineers working on SOH estimation and related research, thus further promoting the development of SOH estimation technology and exploration of potential research direction.
