Abstract
A charge/discharge control circuit comprises two serially connected electric power sources and two overcharge/overdischarge detection circuits. A control circuit outputs a signal for controlling the charge/discharge of the electric power sources in accordance with signals from the two overcharge/overdischarge detection circuits. An intermediate voltage receiving circuit receives, in accordance with the signal from the control circuit, a voltage at a junction point between the two electric power sources and outputs a signal indicative of a relation of the relative voltage between the two electric power sources.
