Abstract
An assembled battery () provided by this invention has a plurality of secondary batteries () connected in series, and has a first bypass circuit () including a Zener diode () connected in parallel so that the connection is in the inverse direction during charging with respect to the series connections, and a second bypass circuit () including a varistor () connected in parallel to the secondary batteries () and the Zener diode (). The Zener voltage of the Zener diode () is set to a prescribed first voltage value, and the varistor voltage of the varistor () is set to a second voltage value equal to or greater than the first voltage value.
