An incipient fault, unlike other types of faults in battery systems, is characterized by its gradual and subtle development, making it difficult to detect using traditional fault detection methods that rely on sudden or large deviations from normal operating behavior. It represents the initial stage of a fault that is slowly emerging, as opposed to a sudden or catastrophic failure. The key distinction is the magnitude and rate of change of the fault's impact on the battery's behavior. Other types of faults, such as a short circuit or a sensor failure, typically cause large and abrupt changes in voltage, current, or temperature that are easily detected. An incipient fault, on the other hand, causes only small and gradual changes that can be easily masked by normal operating variations, sensor noise, or modeling errors. For example, a gradual increase i....
