According to the present invention, an electric vehicle charger fire detection system using a light-receiving lens and a sensor, comprises: an electric vehicle charger; and an electric vehicle charger fire detection device using a light-receiving lens and a sensor, installed in the electric vehicle charger to monitor and block an electric fire. The electric vehicle charger fire detection device using a light-receiving lens and a sensor, includes: an electric fire detection unit including a plurality of detection units which are a sensor having a light-receiving lens to detect a parameter for determining an electric fire; and a body unit for receiving the parameter detected by the electric fire detection unit to calculate an electric fire risk index (EFRI), and comparing the same with a reference threshold value to determine the occurrence of a fire. The electric fire detection unit includes a horizontal rotating detection module having a CO detection unit, an infrared flame detection unit and an ultraviolet detection unit mounted with a light-receiving lens in a front side in a cylindrical shape. Accordingly, the number of used sensors can be reduced by expanding a monitoring range using a light-receiving lens with a wide angle of view to monitor ultraviolet rays, visible rays, and infrared rays of flame generated during a fire inside or outside an electric charger.
