  • Power source device, electric vehicle comprising power source device, accumulator device
    Patent number: 9673430
    Abstract: A power supply device comprises plural battery cells having electrode portions, and bus bars connecting the electrode portions of the plural battery cells each other. The bus bar comprises a thin portion thinner than the other portion formed in at least one part of the end edge of the bus bar, and are welded to the electrode portion of the battery cell through the thin portion. The electrode portion comprises a pedestal portion, and an electrode terminal projecting from the pedestal portion, and the thin portion is disposed at the side surface of the electrode terminal. By this, at the time of welding the bus bar the thin portion is directly welded to the electrode portion, and without using other parts of the welding ring or the like the welding process is streamlined.
    Type: Grant

  • Battery having welded lead plate
    Patent number: 6379839
    Abstract: The battery has an electrode assembly inserted into a cylindrical external case. A lead plate connected to the electrode assembly is weld attached to the inner surface of the external case by an energy beam applied from outside the external case. The external case has a projection jutting from its inner surface. The energy beam is applied to the projection from outside the external case and weld attaches the lead plate to the inner surface of the projection.
