  • Patent number: 11205820
    Abstract: In an upper cell unit (2146) and a lower cell unit (2147) comprising five battery cells, positive electrode terminals (2162, 2172) are set apart and aligned vertically, and negative electrode terminals (2167, 2177) are set apart and aligned vertically. When an electrical device body is rated at 36V, device-side terminals are in contact only at the upper terminals (2162, 2167), and short circuiting of the lower terminals (2172, 2177) is effected using a short bar 2059. When the electrical device body is rated at 18V, the upper and lower terminals (2162 and 2172, 2167 and 2177) are simultaneously made to contact the device-side terminals, and the upper cell unit (2146) and the lower cell unit (2147) assume a parallel connected state. Thus, it is possible to automatically switch the output voltage when a battery pack is mounted according to the difference in terminal shape on the electrical device body side.
