Abstract

Each battery block is formed by a plurality of unit cells arranged. Coupling a plurality of battery blocks with each other forms a battery module. Guiding members, through which a rail is made to pass, is provided on an external surface of the battery block, where the rail is used to couple the battery block with another battery block. The guiding members are provided on at least two adjacent lateral faces of four lateral faces excluding electrode faces of the battery block.

Claims

1. A battery block formed by a plurality of unit cells arranged, wherein a guiding member, through which a rail is made to pass, is provided on an external surface of the battery block, the rail being used to couple the battery block with another battery block.

2. The battery block according to claim 1, wherein the battery block is formed in a rectangular parallelepiped shape, and

wherein the guiding member is provided on at least two adjacent faces of four faces of the battery block excluding two faces, positioned opposite to each other, on which a cathode external terminal and an anode external terminal thereof are arranged, respectively.

3. The battery block according to claim 2, wherein the guiding member is provided in an orientation such that the rail passes through in a direction parallel to a face where each of the cathode external terminal and the anode external terminal is arranged on each of their mounting surfaces, and

the guiding member is provided in a position where distances between the guiding members and the face having either the cathode external terminal or the anode external terminal are equal.
