Abstract
A system in an electric or hybrid vehicle includes two or more battery packs to power one or more motors of the vehicle to move the vehicle. A controller dynamically activates an operational mode of the vehicle during vehicle operation, the operational mode being one of a plurality of possible operational modes. Each of the possible operational modes defines which of the two or more battery packs are connected to the one or more motors and, based on two or more of the two or more battery packs being connected to the one or more motors, also defines an interconnection among the two or more of the two or more battery packs. The plurality of possible operational modes includes a first operational mode defining a series connection between the two or more battery packs and second operational mode defining a parallel connection between the two or more battery packs.
