Abstract

A battery unit has a battery encapsulation formed by first and second encapsulation parts joined by a weld along a weld zone, with a battery contained in the battery encapsulation between the first and second encapsulation parts. Either the battery has a recess exstending along the weld zone, or overlaping edges of the first and second encapsulation parts are bent away from the battery to form a recess. The recess provides a heating insulating space that protects the battery from damage during welding along the weld zone.
