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.

Abstract: An electric vehicle charge equipment (EVSE) for supplying a charge current to an electrical vehicle includes: a liquid cooled charge cable with a charge connector for connecting to the electrical vehicle; and a charge current regulating device for regulating the charge current based on a temperature of the cooling liquid. Regulating the charge current includes: charging the electrical vehicle with a first charge current for an initial time period and thereafter charging the electrical vehicle with a second charge current that is greater than the first charge current, and/or reducing the charge current as long as the temperature of the cooling liquid is below a temperature threshold, and/or charging the electrical vehicle with a first charge current as long as the temperature of the cooling liquid is below a temperature threshold and thereafter charging the electrical vehicle with a second charge current that is greater than the first charge current.
