The present invention relates to an electric vehicle charging control system, which detects characteristics of a device connected to a charging terminal when charging an electric vehicle to prevent an electric device, an electric heater, and the like from being connected and used, and detects a charge current amount to block a charge current depending on an overcurrent flow and a buffer state. Therefore, in a small electric vehicle charger installed and operated in a long-term parking facility such as an existing public parking lot, when other electronic devices other than an electric vehicle are connected, the electric vehicle charging control system detects impedance characteristics of an electronic device connected to the charge terminal to cut off power, and also detects overcurrent supply to cut off power, thereby improving the safety of the electric vehicle charger.

    본 발명은 전기자동차의 전원 충전 중에서 충전단자에 연결되는 기기의 특성을 감지하여 임의로 전기기기 및 전열기기 등을 연결하여 사용할 수 없게 하며, 충전 전류량을 감지하여 과전류 흐름과 완충 상태에 따라 충전 전류를 차단할 수 있는 전기자동차 충전 제어 시스템에 관한 것으로, 기존의 공공 주차장과 같은 장기 주차장 시설에 소규모의 전기자동차 충전기를 설치 운영시 임의의 사용자가 다른 용도로 활용하는 경우, 충전단자에 연결된 전자기기의 임피던스 특성을 감지하여 전기자동차가 아닌 다른 전자기기들이 연결되었을 경우 충전전원 공급을 차단하고, 과전류 공급을 감지하여 감지전원을 차단함으로써 전기자동차 충전기의 안전성을 향상시킬 수 있는 효과가 있다.
