Abstract
A system and method for charging an electric vehicle includes a calibrated energy meter and a calibrated time meter, wherein the calibrated energy meter is characterized by a minimum charge current that is accurately measurable due to the calibration. The system and method is configured, when charging the electric vehicle with an actual charge current during a charging session, for initially metering the actual charge current with the calibrated energy meter as long as the actual charge current is in a range between the rated charge current and the minimum charge current or a value related to the minimum charge current and thereafter, when the metered charge current falls below the minimum charge current (Imin), for metering a charge time with the calibrated time meter until the charging session ends.
