Capacity Fade Modeling of a Lithium-ion Battery for Electric Vehicles
This paper introduces a capacity fade model for Lithium-Ion batteries based on Single Particle model (SP model), a type of reformulated form of Psuedo 2D model first proposed by Doyle et al. The model simulates the loss of active material in the cathode and formation of solid electrolyte interphase (SEI) in the anode, resulting in capacity fade and resistance increase. The numerical model was suggested for the calculation of voltage profiles and parameters for capacity fades were determined so that cell testing data fit to calculated results. The results show that tested cell experienced about 34% loss of active material and 0.06 Ωm2 impedance increase after 3000 charge-discharge cycles. The developed methods can be used not only to calculate the performance degradation for battery pack by scaling up to vehicle level, but also to cascade targets for cell- module-pack-vehicle levels. The further studies were planned to investigate capacity fades for vehicle driving.
