The invention relates to means for a calibration standards-compliant determination of the electrical energy transferred from a charging station, which make a measurement at the transfer point, that is to say at the vehicle-side end of the charging cable, unnecessary. Here, the electrical energy transferred from a charging station is determined by a measurement of the energy before the transfer point, wherein the reactive power component from the termination point as far as the transfer point is compensated. The reactive power component is determined from at least one second electrical variable, for example a resistance of a conductor or a conductor shield, which is in a fixed relationship with an analog electrical variable that is relevant to the transferred electrical energy, for example an ohmic total resistance of at least two conductors involved in a charging circuit.
A measuring apparatus for capturing electrical energy transferred from a charging station, wherein a charging cable for forming an electrical connection between a connection point of the charging cable on the charging station and a transfer point of the charging cable on an energy sink is at least sometimes assignable to the charging station, and wherein the charging cable comprises a conductor set having a plurality of conductors, wherein the measuring apparatus comprises:
