Carregadores de veículos elétricos e seu impacto na qualidade da energia elétrica

Abstract

With the intent of promoting a more sustainable socio-economic development and reducing the impacts caused by combustion vehicles, there is a growing incentive to use electric or hybrid cars as an alternative to the conventional ones. However, the viability of these vehicles is still questioned due to the autonomy of the batteries and the structure of the electricity network needed to supply their charging. This work aims to measure the impacts of the insertion of a charging system for electric vehicle batteries in the electric distribution network and compare it to the main indicators of the quality of the electric power described in PRODIST’s module 8, verifying the possible consequences that this change of technology for transportation may imply from the electric power distribution point of view. Modelling a DC-DC Boost converter of an electric vehicle charger with duty cycle control for power factor correction, it is possible to notice a great reduction in the magnitude of the peak of the input current as well as in the harmonic distortion level, approaching the power factor to the unitary value and complying with the established electric power quality indicators.
