Abstract
A battery-condition monitoring operation is performed by connecting a load resistor across the battery terminals for a time interval to draw a definite battery discharge current. A metering unit measures the voltage across the load resistor or that directly across the terminals of the battery. A timing switch sensible to the temperature of the load resistor automatically terminates the time interval, and a start switch is pressed to initiate the time interval; alternatively, the timing switch automatically initiates the measurement at successive time intervals. Latest at the end of the time interval, an arresting device prevents the metering unit from responding further to the metered signal, and the value most recently metered by the metering unit is persistently held, until the next such measurement operation, and constitutes an indication of the remaining capacity of the battery.
