Abstract

In this paper, the charging current harmonics of EV are analyzed based on the harmonically coupled admittance matrix of three-phase rectification charger. The harmonic current calculation formula of single and multiple EV chargers in the grid is derived, and subsequent a probability method to assess the top oil temperature, hotspot temperature, relative aging rate and loss-of-life of distribution transformer affected by the charging current harmonics of EV chargers is proposed using the harmonic loss factor to quantify the impact of harmonic current on transformer and combining the probabilistic simulation method of charging load for multiple types of EV.
