Characterizing the degradation process of Lithium-Ion Batteries using a Similarity-Based-Modeling Approach

Authors: L. Quintero, Vanessa; Perez, Aramis; Jaramillo, Francisco; Orchard, Marcos

Description: This article proposes a Similarity-Based-Modeling (SBM) approach capable of characterizing the degradation process of a lithium-ion (Li-ion) battery when discharged under different current rates and different State-of-Charge (SOC) ranges. The degradation process can be represented through a biexponential model. In this regard, it is possible to determine the equivalent cycle-by-cycle efﬁciency which has low values at the beginning of the degradation process until it reaches a higher and steady value. The lifespan of the batteries is analyzed through the use of Monte Carlo simulations which intends to represent a more realistic way of how the batteries are used.
