چکیده :

In this paper, an adaptive observer is proposed to detect voltage sensor fault and state of charge fault in a battery management system of an electric vehicle considering the ageing effect. Aging mechanism in lithium-ion batteries will lead to a decrease in capacity and a rise in resistance of the whole cell. In designing the observers, calendar and cycle ageing effects on the capacity and resistance of the battery cell are modeled as unknown parameters, and adaptive observers will update these estimating ageing parameters to have a more accurate fault detection for aged batteries. Some Simulations have been conducted on a Li-ion cell to demonstrate the performance of the proposed approach
