At least two module batteries are arranged and connected by wiring. The outside surface of a first side wall of a box faces a first direction and does not face the remainder of the at least two module batteries. A second side wall and a third side wall of the box are separated in a second direction. The first direction and the second direction are perpendicular. At least two string groups are linearly arranged in the second direction. A positive electrode bus comprises a positive electrode collector, a positive electrode extension section and a positive electrode penetration section. The positive electrode collector follows along the inside surface of the second side wall. The positive electrode extension section follows along the inside surface of the first side wall. The positive electrode penetration section penetrates the first side wall. The positive electrode collector, the positive electrode extension section, the positive electrode penetration section, and the wiring are conductive. A negative electrode bus also has a similar structure. |
