Title:
EARTH LEAKAGE CIRCUIT BREAKER FOR ELECTRIC VEHICLE CHARGER
Document Type and Number:
WIPO Patent Application WO/2018/124374
Kind Code:
A1
Abstract:
The present invention comprises: a plurality of switches connected respectively to a current transfer line and a feedback transfer line between an external power source and a load; a diagnostic unit connected to a diagnostic line so as to output diagnostic current; an earth leakage sensor arranged to encompass the current transfer line, the feedback transfer line, and the diagnostic line, and sensing leakage current therefrom; and a control unit controlling opening/closing operations of the plurality of switches according to a comparison result between the leakage current and a reference value so as to control the connection between the external power source and the load, and thus the present invention has an advantage of allowing an electric vehicle charger to perform a self-diagnosis in real time.
