Abstract
A method for gathering information from battery sensors—for instance, information regarding the state-of-charge (SOC), temperature and/or other characteristics of battery cells in a vehicle battery pack—and using that information to estimate or predict battery degradation or state-of-health (SOH). According to an exemplary embodiment, the method uses both a time-based algorithm and an event-based algorithm to predict or estimate battery degradation. The event-based algorithm may select certain data from the battery conditions (e.g., a state-of-charge (SOC) swing (ΔSOC) or an SOC maximum (SOC)), instead of using the entire set of battery condition data, and may use this information in its prediction or estimate.
