Abstract
A battery assembly (10) includes at least one battery cell (12) and a circuit carrier (15) in thermal proximity to the at least one battery cell (12). Located on circuit carrier (15) is a thermal fuse (18) which is formed from an electrically conductive resilient material such as beryllium copper. At least one end of the thermal fuse is coupled in a deflected state to a solder pad (20) located on circuit carrier (15) using a low temperature conductive adhesive such as low temperature solder (24). When the temperature of the at least one battery cell (12) reaches a predetermined trip point, the one end of the thermal fuse releases away from solder pad (20) due to the heat transfer from the at least one battery cell, thereby electrically disconnecting the at least one battery cell (12) from battery terminal (23).
