Impact of EV Chargers on Total Harmonic Distortion in the Distribution System Network

Abstract

Battery electric cars are mostly charged by on-board chargers, which are connected to the distribution grid. Charging of Electric Vehicles (EVs) increases additional energy demand to the grid. The main goals of each charging strategy are to charge EV in distribution grids with the lowest price electricity, provide stability during charging and prevent over-demand of energy. The main purpose of the research is to show the effect of harmonics of voltage and current on the low voltage network during charging of an EV.
