Abstract: A battery pack includes a housing defining an interior volume, a cell pack assembly positioned within the interior, a printed circuit board electrically connected to battery cells, electrical contacts in communication with the battery cells via the printed circuit board and providing electrical power to an external device and a detector in electrical communication with the printed circuit board. The cell pack assembly includes battery cells that collectively define a volume, wherein each battery cell includes a body, an anode extending from the body, and a cathode extending from the body. The body of each cell is configured to expand and contract. When the detector determines that the volume of the battery cells meets or exceeds a threshold volume, the detector is configured to generate a signal configured to warn the operator of a status of the stack or stop current from flowing to and from the battery cells.

Abstract: A battery pack has a housing, a core box, a stack of pouch cells, an end plate, battery pack terminals, and a circuit board. The core box is disposed in the housing and has a support surface. The stack of pouch cells are supported by the support surface. Each pouch cell has cell tabs that extend from a common side of the pouch cell. The end plate has slots, and the cell tabs extend through the slots. The battery pack terminals are electrically connected to the stack of pouch cells and can be electrically connected to an electrical device. The circuit board is coupled to the core box opposite the support surface. The circuit board is electrically connected to the stack of pouch cells and the battery pack terminals. The core box, the end plate, and the circuit board cooperate to enclose the stack of pouch cells.
