COMMUNICATION INTERFACE SYSTEM FOR CHARGING BATTERY OF ELECTRIC VEHICLE AND CHARGING METHOD USING THEREOF, ELECTRIC VEHICLE HAVING COMMUNICATION INTERFACE SYSTEM FOR CHARGING BATTERY

摘要

The present invention relates to a communications interface system for charging a vehicle battery, a method for charging a vehicle battery using the same, and an electric vehicle with the communications interface system, and more specifically, to the communications interface system for charging a vehicle battery, the method for charging a vehicle battery using the same, and an electric vehicle with the communications interface system, wherein the communications interface system defines a coupler connection state of an electric vehicle supply equipment (EVSE) and a charging limiting current instruction in a charging system interface protocol as an interface item used while communicating with a battery management system (BMS), thereby enabling a electrically and functionally stable charging operation.
