This work aims to verify the impact of voltage dips propagated from the transmission grid on EV charging stations. Previous works in this topic have applied voltage dips directly to the terminals of the EV chargers, i.e. neglecting the transfer between the source of the dip and the EV chargers stations. Moreover, some works limited their analysis by considering only the magnitude and duration of voltage dips. This work aims to verify if the impact of dips on EV charging stations is distinct when considering the propagation and detailed characteristics of the dips. This work shows that the non-consideration of the propagation and detailed characteristics of the voltage dips might underestimate the impact on the EV charging station.
