Abstract
A battery pack (10) including at least one battery cell (26) and a circuit carrier (30) in proximity to the battery cell. Disposed in the battery pack, is a fuse (50) which is formed from an electrically conductive resilient material adapted to work as the fuse. The electrically conductive resilient material further is encapsulated with a material adapted to promote resistance to breakage due to shocks, bumping or droppage of battery packs into which the fuse is incorporated. When the temperature of the at least two battery cells reaches a predetermined trip point, the fuse releases from at least one of the batteries, due to the heat transfer from the battery cell, electrically disconnecting the battery cell from adjacent battery cells.
