The present invention relates to a roaming system for charging an electric car, which provides roaming service for charging an electric car, and comprises a roaming management unit, wherein when receiving a request for charging a charger managed by a roaming system for charging an electric car from a user who did not subscribe to a roaming system for charging an electric car, a roaming management unit interworks with a charger and permits a user who did not subscribe to a roaming system for charging an electric car to use a charger if a user can roam. The charger capable of roaming for charging an electric car comprises a control unit, wherein when receiving a request for charging from a user who did not subscribe to the roaming system for charging an electric car, the control unit interworks with the roaming system for charging an electric car and permits charging of the user who did not subscribe to the roaming system for charging an electric car if the user can roam. The roaming server for charging an electric car comprises a roaming control unit, wherein when receiving a request for charging through a charger managed by a first electric car-charging system from a user who subscribed to a second electric car-charging system, the roaming control unit identifies whether the user can roam, and interworks with the charger and permits use of the charger according to a charging request by the user who can roam.
