초록

A device for determining the charge status of a battery (4) when it is discharged by a load (RL) and/or when it is charged by a power-supply circuit (1) in which a value representing the nominal charging time and discharging time respectively is stored in first (10) and second adjusting means (11) respectively and is applied to computing means (12). In response to clock pulses applied to the computing means by a clock means (13), the computing means calculate the charge status of the battery by expressing the elapsed discharging or charging time as a fra...
