ELECTRIC VEHICLE, CHARGING STAND, AND METHOD FOR CHARGING THE ELECTRIC VEHICLE
First Claim
1. An electric vehicle comprising:
- a battery management system (BMS) for managing a state of a battery pack in response to charging of the pack or operating power supplied from the battery pack;
a charging unit for charging the battery pack using a charging current supplied through a connector;
a vehicle communication unit for communicating with a charging stand through a communication terminal included in the connector; and
a vehicle control module (VCM) for, upon receiving a request from the charging stand during vehicle charging, transmitting vehicle information including not only unique vehicle information but also a battery-pack charging state received from the battery management system (BMS) to the charging stand through the vehicle communication unit.

Abstract
The present invention relates to a system for charging an electric vehicle and to a method for charging the electric vehicle. A charging stand which supplies electric power for charging to the electric vehicle performs user authentication or vehicle authentication for the electric vehicle to be charged, so as to prevent unauthorized charging or theft and thus enable the electric vehicle to be stably charged. In addition, a connection circuit is used as a connection cable or a connector for charging, which interconnects the vehicle and a charging side by means of a single line to enable both the vehicle and the charging side to recognize the interconnection, thus simplifying the configuration of the circuit for enabling the vehicle and the charging side to recognize the interconnection, and enabling both the vehicle and the charging side to easily recognize whether or not they are interconnected.
