To cope with restrictions, the fault can be incorporated into a battery state (e.g., short circuit (SC) current, sensor fault) as U 1, S O C, f T , . The fault severity can be directly estimated from the battery state, which leads to the improvement in fault response time and fault estimation accuracy.
Changes in the state are recorded to achieve battery fault diagnosis. The method is validated using real-world operation data from four EVs with varying specifications. In Ref., an efficient fault diagnostic scheme for battery packs is proposed. The scheme utilizes a novel sensor topology and a signal processing procedure.
In-situ diagnosis is a promising trend, allowing for real-time monitoring of battery health during operation. This approach uses embedded sensors to capture data and adaptive algorithms to adjust fault detection thresholds based on battery behavior.
