The present invention relates to an electric vehicle charging system capable of preventing an accident due to heterogeneous abnormal current. The electric vehicle charging system allows or blocks the flow of alternating current flowing in an alternating current power line according to the generation of heterogeneous abnormal current in the alternating current power line by using an alternating current sensor which is installed in the alternating current power line and detects a low frequency component and a high frequency component in the alternating current flowing in the alternating current power line, thereby preventing an electric vehicle charging accident due to the generation of heterogeneous abnormal current in the alternating current power line by detecting heterogeneous abnormal current which can be generated in the alternating current power line such as arc and overcurrent by using one current sensor.

    이종의 이상 전류로 인한 사고를 방지할 수 있는 전기차충전시스템에 관한 것으로, 교류전원선에 설치되어 교류전원선에 흐르는 교류 중에서 저주파 성분과 고주파 성분을 검출하는 교류겸용센서를 이용하여 교류전원선에서의 이종의 이상 전류의 발생 여부에 따라 교류전원선에 흐르는 교류의 흐름을 허용하거나 차단함으로써 하나의 전류 센서를 이용하여 아크, 과전류 등 교류전원선에서 발생 가능한 이종의 이상 전류를 검출하여 교류전원선에서의 이종의 이상 전류 발생으로 인한 전기차 충전 사고를 방지할 수 있다.
