Battery module

摘要

A battery module includes: a plurality of connecting members electrically connecting electric terminals of adjacent electric cells; and a flexible flat cable formed by flatly encapsulating an outer circumference of a flat conductor with an insulating resin and joining the plurality of connecting members. Portions of the flexible flat cable to be disposed between adjacent connecting members are provided with folded portions formed by folding the flexible flat cable at folded lines. The folded lines extend in a direction crossing a longitudinal direction of the flexible flat cable.

1. A battery module comprising:
electric cells each having a positive electrode terminal and a negative electrode terminal, the electric cells being aligned with each other; connecting members electrically connecting the electrode terminals of electric cells adjacent to each other; and a flexible flat cable including a flat conductor and an insulating resin that surrounds an outer circumference of the flat conductor and jointing the connecting members, the flexible flat cable including portions each of which is disposed between adjacent connecting members and is a folded portion that is folded at a folding line, the folding line extending in a direction crossing a longitudinal direction of the flexible flat cable, the flat conductor including conductors that are aligned with each other and are laminated with the insulating resin, and each of the conductors of the flexible flat cable including a single connecting portion that is exposed and electrically connected to a single corresponding connecting member of the connecting members, the insulating resin being peeled at the connecting portion.
