Abstract: At present, there is no effective traceability system for the value of DC electric energy. DC electric energy cannot be measured and traced to the national standard, which is not convenient for accurate billing and settlement. This paper studies the on-site calibration technology of DC charger electric energy measurement, analyzes the error of DC electric energy measurement, and proposes a scientific and feasible DC energy measurement traceability scheme, which provides important support for ensuring the accuracy of DC measurement. The experimental results show that the on-site verification and error analysis method of DC charging electric energy measurement proposed in this paper is feasible and effective.

Key words: DC charger, electric energy measurement, accuracy, traceability
