Abstract
A battery diagnostic system stores capacity degradation models for batteries of a specific type mapped to sets of battery cycle models formed by voltages and/or currents measured at different capacities. Each capacity degradation model is mapped to a set of battery cycle models associated with different battery capacities. The system, upon accepting measurements indicative of a battery cycle and a current capacity of the test battery, compares the battery cycle of the test battery with the battery cycle models of different capacity degradation models associated with a value of the battery capacity closest to the current capacity of the test battery to select a battery cycle model closest to the battery cycle of the test battery and the degradation capacity model mapped to the selected battery cycle model. The system estimates future degradation of the capacity of the test battery based on the retrieved capacity degradation model.
