Abstract

Presented a method for designing aging experiments to aid in fitting aging models Demonstrated this method with LiFePO4 cells By placing the batteries in different cycling scenarios we observed three distinct aging behaviors Normal use: These cells age in the "expected" way when considering amp-hours processed Light use high voltage: These cells age quickly in comparison to amp-hours processed Light use low voltage: These cells age slower in comparison to amp-hours processed This method can be readily applied to other battery types and chemistries to develop aging models.
