This abstract first appeared for US patent application 18602319 titled 'Control Strategy for Mixed Chemistry Battery Pack

Original Abstract Submitted

An electrical system includes a high-voltage battery pack assembly having a first cell set with a first group of energy storage cells and a second cell set having a second group of energy storage cells connectable to the first cell set. The first cell set includes at least one first battery chemistry cell and the second cell set includes at least one second battery chemistry cell. At least one switch is in electrical communication with the first or second cell set. Battery connection terminals are in electrical communication with at least one of the first or second cell sets. A controller is configured to determine an operating strategy of the high-voltage battery pack assembly and place at least one of the first cell set or the second cell set in electrical communication with the battery connection terminals in response to the operating strategy of the high-voltage battery pack.
