Battery module

摘要

A battery module is fabricated as follows. A plurality of elements for electromotive force is accommodated in a one-piece cylindrical case and is arranged in series in an axial direction of the case. The elements for electromotive force are electrically connected through an electric connector passing through a resin partition wall which separates the elements for electromotive force from one another. The both ends of the case are sealed with sealing plates.
