Abstract

A battery protection device operates in conjunction with at least one battery. The battery has at least two conducting terminals and at least one conducting lead-in. The conducting lead-in is in contact with the conducting terminals for conducting circuits. The battery protection device comprises at least one cut-off unit. When the ambient temperature is higher then a predetermined value, the cut-off unit deforms itself and separates the conducting lead-in and the conducting terminal for cutting off the circuits. Wherein, the materials of the cut-off unit are Shape Memory Alloy (SMA). The battery protection device further comprises at least one reposition unit. When the ambient temperature is lower then the predetermined value, the reposition unit recovers back to its original shape. Then the reposition unit reconnects circuits by making the conducting lead-in contact the conducting terminal.
