CHARGING APPARATUS AND METHOD OF OPERATING THE SAME

A charging apparatus for use with an electric vehicle includes a power transmission path, a switch, a first controller, a communication unit, and a second controller. The switch is disposed on the power transmission path. The communication unit is coupled to a second connection port. The first controller is coupled to the power transmission path, the switch, the second controller, and the communication unit. When the second controller receives a first request from a power management system and correspondingly notifies the first controller, the first controller switches from a first signal to a second signal to communicate with the electric vehicle and turns off the switch, and when the first controller receives a first EV notification provided from the electric vehicle, the controller turns on the switch.
