This paper describes a new traceable measurement system, designed for the characterization of inductive charging stations for electric vehicles. The measuring system is able to measure on-site the performance and efficiency of the charging station and converters. The basic relative uncertainty is 10-3 but actual measurement conditions could worsen this figure. The measurement system aims at accurately measure the power at the batteries and the power transferred from the ground to the onboard resonant circuit and makes possible a benchmarking between station measuring systems. Finally, it allows the characterization of the magnetic emissions by correlating them with the electric current in the coils.
