  • Activation mechanism for a reserve battery cell
    Patent number: 9647276
    Abstract: A biasing mechanism for pressurizing an electrolytic solution of a reserve battery cell, the biasing mechanism containing a compressed spring and a trigger operatively associated with the compressed spring. The trigger is configured to release the compressed spring to pressurize the electrolytic solution.
    Type: Grant

  • Contoured battery case based on cell shapes
    Patent number: 9190642
    Abstract: A battery case houses a battery with a plurality of non-prismatic electrochemical cells and at least one electronic component. The battery case includes a plurality of cell housings and at least one electronic component housing that accommodates the at least one electronic component. The plurality of cell housings each (1) define an internal space sized to accommodate one of the electrochemical cells, and (2) include (a) an internal surface at least a portion of which is shaped to substantially correspond to a non-prismatic exterior surface of the one of the electrochemical cells to be housed by the cell housing, and (b) an external surface at least a portion of which follows contours of a corresponding portion of the inner surface.

  • Activation mechanism for a reserve battery cell
    Patent number: 8603658
    Abstract: An activation mechanism for a reserve battery cell generally includes a housing with a chamber containing an electrolytic solution and a delivery device configured to discharge the electrolytic solution from the housing. The delivery device includes a compressed spring configured to be released in response to an external force to initiate the discharge of the electrolytic solution from the housing.
