Provided are an electric vehicle charging apparatus, a system thereof, and an operation method thereof. The electric vehicle charging apparatus according to one embodiment of the present invention comprises: a charging electricity conversion unit which receives an alternating current electricity from a grid and converts the same into a direct current electricity; and a charging electricity control unit which supplies the converted direct current electricity to an electric vehicle or an energy storage device. When charging the electric vehicle, the charging electricity control unit connects the direct current electricity supplied to the energy storage device and the direct current electricity converted from the alternating current electricity supplied from the grid in parallel and supplies the same to the electric vehicle. Provided are the electric vehicle charging apparatus capable of supplying the stored direct current electricity in parallel, the system thereof, and the operation method thereof.
