摘要

本文建立了商用锂离子电池的连续离散动力学模型。通过等效电路对其进行建模，采用时域参数提取方法确定其值。由于参数根据电池的充电状态而变化，使用Simulink®Design Optimization™提出了基于最小二乘法的参数识别程序。

State-space modelling of a commercial lithium-ion battery

In this paper, a continuous and discrete-time dynamical model of a commercial lithium-ion battery is proposed. It is modelled through an electrical equivalent circuit, applying the method of parameter extraction in the time domain to determine its values. As parameters vary according to the state of charge of the battery, a procedure for parametric identification based on the least-squares method is presented, using the Simulink® Design Optimization™.
