CHARGING SYSTEM FOR ELECTRONIC VEHICLE AND METHOD FOR REMOVING HARMONIC THEREOF

摘要

An electric automobile charging system according to an embodiment of the present invention comprises: a first charger for receiving three phase alternating power from a system and supplying charging power for an electric automobile by using the three phase alternating power; and at least one second charger for receiving three phase alternating power from the system and supplying charging power for the battery of the electric automobile. The first charger removes a harmonic wave component included in current waves flowing therefrom to the system and current waves flowing from the second charger to the system.
