Abstract: To guarantee an accurate energy measurement, the DC meter must withstand the occurring disturbances without losing its measurement accuracy. This must be proven during conformity assessment of the electricity meter. This paper investigates disturbances occurring on the DC side of charging stations for electric vehicles for a set of different charging stations and electric vehicles. Furthermore, a testbed for DC energy meters is presented which is able to generate combined voltage and current signals, consisting of the DC signal and an additional AC interference up to 150 kHz. To enhance the accuracy of the AC signal measurement a method for compensating the DC component is used.
