摘要: 简述了锂离子电池等效电路模型和电化学模型的研究进展。由于具有耗时短、技术开发效率高等优点,仿真模型被广泛应用于锂离子电池衰减机制分析、状态诊断及寿命预测。锂离子电池仿真模型主要包括等效电路模型和电化学机理模型。等效电路模型主要应用于锂离子电池荷电状态诊断。电化学机理模型主要应用于锂离子电池衰减机制分析和健康状态诊断,并为寿命预测提供技术支持。等效电路模型的结构过于单一,在锂离子电池寿命后期适用性降低。电化学机理模型结构复杂,计算量大,在线性应用能力较差。总结了现阶段常用的锂离子电池等效电路模型和电化学模型的建模原理及模型结构,阐述了每种模型在电池研究中的具体应用,并分析了其各自的优势及局限性。通过以上分析,并结合最新的建模理论,对建立具有高精度、高适用性锂离子电池仿真模型的研究方向进行了展望。

Abstract: The models of lithium-ion batteries, including equivalent circuit models and electrochemical models, are reviewed. Models are used for the degradation mechanisms analysis, state estimation and life prediction of lithium ion batteries due to the time-effectiveness and applicability. The equivalent circuit models are more applicable for state of charge estimation and the electrochemical models are suitable for the degradation analysis and state of health estimation of lithium ion batteries. The simple and fixed model structure for equivalent circuit models and the complicated model structures and heavy computation for electrochemical models limit their application. The authors summarize the principles and structures of equivalent circuit models and electrochemical models. Then the application of these models is described and the merits and limitations of each model are elaborated. Then, based on the analysis mentioned above and the state-of-the-art modelling theory, the future research direction on more accurate and universal battery models is put forward.
