  • Publication number: 20140302356
    Abstract: A battery module includes a cell unit, a first end plate, and a binding band. The cell unit includes a plurality of battery cells arranged in a first direction. The first end plate is located on one side of the cell unit in the first direction. The binding band extends in the first direction and is coupled with the first plate so as to bind the first end plate and the cell unit. The first end plate has an external terminal surface directed to an opposite side with respect to the cell unit in the first direction. An external terminal is connected to the external terminal surface. The binding band is located on a side surface of the cell unit and is coupled with the external terminal surface.

  • Publication number: 20140302357
    Abstract: A battery module has a cell unit including battery cells and a battery monitoring element attached to the cell unit. The battery cells are arranged in a first direction. The battery cell includes pressure release section for releasing a pressure in the battery cell. The cell unit has side surfaces including at least one internal pressure release section surface which is a surface where the internal pressure release section is disposed. The battery monitoring element is disposed on a non internal pressure release section surface which is different from the internal pressure release section surface.

  • Publication number: 20140186688
    Abstract: A sealing member cap, which is to be inserted into a through hole of a cell case of an electric storage device together with a sealing member, includes an insertion portion. The insertion portion has a column shape and includes a recess into which the sealing member is inserted. The insertion portion includes a body section and a large cross-section section. The body section is located in the through hole when the sealing member cap is inserted into the through hole. The large cross-section section is located inside the cell case when the sealing member cap is inserted into the through hole. The recess is larger in cross-sectional area in a plane perpendicular to an axial direction of the insertion portion at the large cross-section section than at the body section.
