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...
A device for indicating the charge status of a battery during charging and/or discharging, comprising: a power-supply circuit for charging the battery and/or energizing a load; means for generating pulses during charging and/or discharging of the battery; computing means for computing the charge status on the basis of the generated pulses, and indicator means for indicating the computed charge status, characterized in that the means for generating pulses comprise clock means for generating clock pulses, the computing means comprise: first adjusting means...
