Abstract
A battery bypass assembly for bypassing for bypassing a first battery cell electrically connected to a second battery cell. The battery bypass assembly has a first bypass contact and a second bypass contact. A voltage sensing mechanism is electrically connected between the first battery contact and the second battery contact for sensing a predetermined voltage loss. An expansive material within the housing expands upon the voltage sensing mechanism sensing a predetermined voltage loss. A plunger mechanism is moveable from a first position to a second position with a maintaining mechanism maintaining the plunger mechanism in the first position and moveable to allow the plunger mechanism to move into the second position. An actuating mechanism contacts the expansive material and the maintaining mechanism for moving the maintaining means upon expansion of the expansive material wherein the plunger mechanism, upon reaching the second position, bypasses the first battery cell.
