Abstract
The paper presents a brief overview of the two main classes of lithium-ion batteries models for battery management systems: empirical and physical. Battery model at the system level is presented as a voltage response to the load or charging current. As an example of empirical model the equivalent circuit based model with linear second-order dynamics for voltage transient and nonlinear dependence of open circuit voltage from state of charge is presented. Class of physical models illustrated by the single-particle model, based on a quantitative description of diffusion processes in the electrodes and the kinetics of ion exchange. This electrochemical model was compared with the empirical equivalent circuit based model. On the basis of analogies proposed equivalent circuit for the single-particle model.

    Алексей Валерьевич, не могли бы вы подсказать примерно параметры для RC цепочки? Литиевый аккумулятор 20Ач. Общее сопротивление порядка 0.002 Ом. Как соотносятся сопротивления и примерный порядок емкостей. Спасибо.
