  • Terminal rail connector on battery stack sides for bus bar module removal
    Patent number: 11502363
    Abstract: A battery pack assembly made up of a battery stack case housing a plurality of battery cells abutting each other is provided for powering a vehicle, such as an electric/hybrid vehicle, and/or a vehicle's electrical components. Each battery cell may be oriented such that their respective terminals alternate in polarity. The respective terminals of each battery cell may be shaped that the terminals frictionally engage a corresponding terminal connector on either side of the battery stack case, and disengage from a corresponding terminal easily. This allows individual battery cells to be replaced/removed without having to remove the entire battery stack.
