  • Battery voltage monitor and disconnection circuit
    Patent number: 5668465
    Abstract: A battery saver circuit compares the battery terminal voltage to a programmable reference voltage and disconnects the battery from the load when the measured battery voltage falls below a predetermined minimum value. The reference voltage is programmable by a transfer function generator which varies the reference voltage in accordance with the current drawn by the load to account for the voltage drop in the line series wiring. A fault indicator is included to prevent chatter in the relay by raising the battery voltage necessary to reconnect the battery to the load. The fault indicator is reset when the battery is recharged.
