Abstract

Measuring transducer for electric vehicles having at least one tap arranged to tap at least one AC measurement value in an AC charging circuit, a transformer arranged to convert a frequency of the AC measurement value into a standard frequency of an energy supply grid and to output at least one AC measurement value with the standard frequency in an AC measuring circuit, and at least one standard meter arranged in the AC measuring circuit for detecting an electrical power with the AC measurement value at the standard frequency.
