Abstract

This thesis takes the Li-ion power battery as the researching object, and makes the experiment comparison on the popular battery dynamic equivalent circuit model. Though the analyzing result of the experiment, and combination of the power battery actual characteristics, the author points out the battery dynamic equivalent circuit model based on the first order RC net, and identificates the parameters, validates the simulation precision. At the same time, basing on this model, the author optimizes the popular estimating method of state of charge of power battery. At last, by the experiment, the thesis validates the precision of the estimating method.
