CHARGING APPARATUS AND CHARGING METHOD OF OPERATING THE SAME

A charging apparatus includes a first terminal, a second terminal, a switch unit, a control unit, and a communication unit. The switch unit is turned on or turned off to control whether the first terminal is coupled to the second terminal. The control unit sets a first time from the switch unit receiving a control signal to the switch unit actually being turned on or turned off. The control unit and the electric vehicle mutually transmit a communication signal through the communication unit. The control unit calculates a second time when the current reaches to a zero point based on an abnormal state indicated by the communication signal, and calculates a third time when the switch unit operates at the zero point based on the first time and the second time, and provides the control signal to turn off the switch unit at the third time.
