Abstract

PURPOSE:To make it possible to perform charging control of a battery having oscillating voltage at a set point of falling voltage of the battery for general use by controlling a timer circuit by detection signal at the close of charging time of the battery. CONSTITUTION:When the charging is commenced, a charging terminal detection circuit 4 and a timer circuit 3 output 'Hi' level, a switch circuit 2 is in a state of 'closed', power supply 1 is connected to a battery 5 to start the charging. In case of battery having oscillating voltage, the charging voltage characteristic peak of the battery until such a time is memorized to the voltage of the battery 5 by a circuit to memorize the peak voltage in possession of the charging terminal detection circuit 4. In other words, when oscillating voltage is lower than the falling V of the charging terminal detection circuit 4, 'Hi' level is outputted and the timer 3 is in a state of resetting, when it is higher than the falling voltage V, 'Lo' level is outputted and the timer 3 operates. After repeating this state, the timer 3 outputs 'Lo' level, the switch circuit 2 is in a state of 'open', the power supply 1 and the battery 5 are cut off and the charging terminates.
