BATTERY PACK HAVING A RUGGEDIZED THERMAL FUSE

摘要

A battery pack (10) including at least one battery cell (26) and a circuit carrier (30) in proximity to said at least one battery cell. Disposed in said 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 said batteries, due to the heat transfer from said at least one battery cell, thereby electrically disconnecting the at least one battery cell from adjacent battery cells.
