Abstract: A pair of end plates is a pair of members provided at both ends of a battery cell assembly in an array direction to clamp the battery cell assembly from both sides in the array direction. The pair of end plates has a plate upper surface and a recess. The plate upper surface is positioned on the same side as that of an electrode mounting surface. The recess is recessed from the plate upper surface and accommodates at least part of a coupling connector. With this configuration, a battery module and a battery monitoring unit mounting structure can prevent the battery module from increasing in size.

Abstract: A battery module includes a cell module including a plurality of battery cells, a smoke exhaust duct protruding from an electrode arrangement surface of the cell module and extending along an alignment direction of the plurality of battery cells, and a circuit board arranged so as to cover the smoke exhaust duct and the electrode arrangement surface. The circuit board is arranged in an inclined state to be non-parallel to the electrode arrangement surface.

Abstract: A fixation structure includes an electrical wire, a board, and a stapler. The electrical wire includes a core wire and a cover member. The electrical wire includes a core-wire covered part covered by the cover member, and a core-wire exposed part exposed from the core-wire covered part. The board includes a junction part electrically connected with the core-wire exposed part. The stapler includes a contact part and a fixation part. The contact part has a plate shape, and is positioned at a boundary between the core-wire exposed part and the core-wire covered part while contacting the core-wire exposed part and the core-wire covered part from a side opposite to the board when the core-wire exposed part is connected with the junction part. A pair of the fixation parts are provided on both sides of the contact part and fix the contact part and the board.
