Abstract Methods and systems for estimating remaining life of an automotive propulsion battery are provided. A total usable capacity of the battery is calculated based on cycling the battery. A first component of degradation is calculated based on driving throughput of the battery. A second component of degradation is calculated based on aging of the battery. The total degradation is calculated based on the sum of the first component and the second component of degradation.
