A COMPARATIVE STUDY OF LI ION TRACTION BATTERIES EQUIVALENT CIRCUIT MODELS FOR ELECTRIC AND HYBRID VEHICLES
The paper presents a comparative study of different equivalent circuit based models of Li Ion batteries. To identify and evaluate the accuracy of battery models, the most representative experimental data we used the time varying charge discharge load regimes that reproduce real or close to real modes of operation of traction batteries, which are used with combined power units as a part of hybrid vehicles. The paper shows the results of simulation of different equivalent circuits with calculation of SOC and losses in the batteries.
