摘　　要：本文对锂离子动力电池的建模理论进行综述,详细介绍了三类动力电池模型,即微观层面的电化学模型、宏观层面时域的集总模型和宏观层面的频域模型,三种模型建模思路及其对应产热模型相互有联系也有区别。电化学模型基于动力电池的内部反应原理,准确度较高但计算复杂。时域集中模型计算量小,但精确度较低,而频域集中模型理论可以对电池内部机理的电化学阻抗谱实验提供理论指导。This article reviews the modeling and theory of lithium-ion power batteries, and introduces three types of power battery models in detail, namely, electrochemical models at the micro level, lumped models at the macro level in the time domain, and frequency domain models at the macro level. The three modeling ideas and their corresponding heat generation models are related to each other and have differences. The electrochemical model is based on the internal reaction principle of the power battery, with high accuracy but computational complexity. The time domain lumped model requires less computation, but its accuracy is relatively low. The frequency domain lumped model theory can provide theoretical guidance for electrochemical impedance spectroscopy experiments of battery internal mechanisms.
