OSTI ID:6842799
A battery-charging system comprises a source of direct current connectable across the terminals of an electrochemical battery, a circuit for connecting the source with the battery, a relay coil, and a Zener-type breakdown device. The circuit includes a switch in series with the battery and the source, the switch having a first position wherein the source is connected with the battery and a second position wherein the source is disconnected from it. The switch is operated by the relay coil. The breakdown device, which becomes conducting upon attainment of a predetermined battery voltage, is connected in series with the coil and the switch for disconnecting the device from the battery. Upon breakdown the coil is energized and the switch is moved from its first position to its second position.
