Abstract

Different state-of-health (SOH) estimation methods for Lithiumion batteries have been proposed in the literature. Even though these methods are showing good accuracy, they are developed for optimal laboratory conditions and do not consider various limitations, which are encountered in real-life applications. Therefore, in this paper, we proposed an alternative method for SOH estimation of NMC-based Li-ion batteries considering a reduced voltage interval for which the capacity fade is determined.For validation of the proposed SOH method, six different calendar aging cases have been considered.
