  • Patent number: 8580427
    Abstract: In this assembled battery, connections between electrode terminals of electrical cells and connection members for the electrode terminal are reliably maintained for a long period of time. The electrode terminal is formed in a tapered pillar shape whose width decreases from the front end of the electrode terminal toward a battery case. Also, a groove, which is shaped from the front end toward the battery case and divides at least a portion of the front end into segmented portions, is provided to the electrode terminal. The segmented portions are elastically deformable to move close to or away from each other. The bus bar (connection member for the electrode terminals) includes a through-hole whose width decreases from the front end of the electrode terminal toward a battery case. The bus bar is fitted to the electrical terminal, by elastically deforming and moving the segmented portions close to each other.
