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.
