This paper presents simple equivalent models of electric vehicle (EV) chargers, based on the measurements of a range of actual EVs. The developed models of the EV chargers are capable of correctly reproducing instantaneous input current waveforms, retaining all relevant electrical characteristics, including harmonic content. To analyse the effects of increased penetrations EV chargers on low-voltage network, the developed EV charger models are combined with the models of existing loads, as a part of the aggregate residential load mix.
