Abstract
An assembled battery includes: a case in which plural electric cells are accommodated; and an abutment member which abuts against the electric cells accommodated in the case to position the electric cells with respect to the case. The abutment member includes a first projection inserted into a first gap defined by the case and the mutually adjacent electric cells to align the abutment member.
Claims19
An assembled battery, comprising:
- a case in which a plurality of electric cells are accommodated, each of the electric cells having a flat rectangular parallelepiped shape;
- and
- an abutment member which abuts against top portions of the electric cells accommodated in the case to position the electric cells with respect to the case,
- wherein the abutment member includes a projection inserted into a first gap defined by the case and mutually adjacent electric cells to align the abutment member, and
- wherein the projection is tapered from its proximal end toward its distal end.
