N2 - Due to the inconsistency of cells or the charger malfunction, the battery may suffer overcharge that damages the battery. The irreversible damage should be detected to reveal the hidden dangers while the batteries operating in its normal SOC range. In this paper, online identification and multi-model adaptive estimation (MMAE), are introduced for the comparative study on overcharge-induced damage diagnosis in the simulation case. Besides, the impact of different filters (Kalman filter, strong tracking Kalman filter, and H-infinity filter) on MMAE are discussed. On this basis, the improved model-based fault diagnosis framework is proposed to achieve better practicability and performance.
