Survey of harmonic emission of electrical vehicle chargers in the European market

This paper presents results of comprehensive tests of 18 different on-board electric vehicle battery chargers (EVBCs), representing the majority of currently available passenger-car-type EVs in the European market. The presented analysis compares the harmonic characteristics of EVBCs, concentrating on the impact of variations in supply voltage magnitude on emission of low frequency harmonics, as well as their total harmonic distortion and total harmonic current indices. The results provide information on the harmonic performance of EVBCs, classification of their harmonic characteristics and their potential impact on harmonic power flows in residential networks.
