Abstract

PURPOSE:To enable automatic charge and charge-stop of a battery by detecting the capacity of the battery by measuring the specific gravity of the electrolyte of the battery automatically by use of an optical means. CONSTITUTION:When the discharge of a battery 2 proceeds, and the specific gravity of the electrolyte decreases, light the amount of which corresponds to the specific gravity of the electrolyte is received by a light receiving part 4, and is converted into an electric signal before it is sent out into a monitoring circuit 5. The monitoring circuit 5 monitors whether the voltage of the battery has reached the Vmin, when the battery requires recharges. When the voltage of the battery is judged to have reached the Vmin, a charge indicating signal (Von N) is sent from a charge indicating circuit 5a, a driving circuit 6 actuates a switching circuit 7 after receiving the signal (Von N), and a contact 7a of the circuit 7 is switched from a terminal 7b to a terminal 7c so as to open a current feeding circuit which feeds current to a load 8. Next, a charging device 9 used for charging the battery 2 is turned on, and the battery 2 is charged with a charging circuit. Following that, as charge proceeds, and the value obtain in the monitoring circuit 5 by converting signals sent from the light receiving part 4 reaches the Vmax, which is the value obtained when the battery 2 is fully charged, a charge stop signal (Voff) is sent out of a charge-stop indicating circuit 5b.
