In this paper, a 3R-C equivalent circuit model is adopted to balance the model accuracy and complexity requirements. The SOH represents the extent of a battery's aging, usually refers to the attenuation of the rated capacity of a battery. When 80% of the rated capacity is reduced to, the battery is considered to have reached its end of life [7, 8].

2018年9月1日 · In developing different ECMs by impedance analyzer fitting, it was proved that the 8RC model is more precise in all frequencies compared to the 2RC and 3RC models. The 8RC circuit fitting leads to 3.3% average error in impedance presentation, while the 3RC and 2RC models are at 20.8 and 29.3%.

In this paper, models with different complexity are studied, from a model with a single RC element to three RC elements. The models are compared, and their suitability for this particular cell is discussed. The 3RC model yielded the best results; however, the differences from the 2RC model are relatively small.
