Title
(DE) TECHNIK ZUR ÜBERWACHUNG EINES KONTAKTS ZWISCHEN LADELEITERN ZUM LADEN EINES ELEKTROFAHRZEUGS
(EN) TECHNOLOGY FOR MONITORING A CONTACT BETWEEN CHARGING CONDUCTORS FOR CHARGING AN ELECTRIC VEHICLE
(FR) TECHNIQUE DE SURVEILLANCE D'UN CONTACT ENTRE DES CONDUCTEURS DE CHARGE POUR CHARGER UN VÉHICULE ÉLECTRIQUE
Abstract
(DE) Eine Technik zur Überwachung eines Kontakts zwischen Ladeleitern (114, 116) einer Ladestation (200) zum Laden eines Elektrofahrzeugs (150) wird beschrieben. Gemäß einem Aspekt umfasst eine Vorrichtung (200) einen Signalgenerator (202), der dazu ausgebildet ist, ein alternierenden Prüfsignal an den Ladeleitern (114, 116) auszugeben; und eine Auswerteeinheit (204), die dazu ausgebildet ist, auf Grundlage des Prüfsignals zu bestimmen, ob zwischen den Ladeleitern (114, 116) ein elektrisch leitender Kontakt besteht.
(EN) The invention relates to technology for monitoring a contact between charging conductors (114, 116) of a charging station (200) for charging an electric vehicle (150). According to one aspect, a device (200) comprises a signal generator (202), which is designed to output an alternating test signal to the charging conductors (114, 116), and an analysis unit (204), which is designed to determine whether an electrically conductive contact exists between the charging conductors (114, 116) on the basis of the test signal.
(FR) L’invention concerne une technique de surveillance d'un contact entre des conducteurs de charge (114, 116) d'une station de charge (200) pour charger un véhicule électrique (150). Selon un aspect, un dispositif (200) comporte un générateur de signal (202) qui est conçu pour générer un signal de contrôle alternatif au niveau des conducteurs de charge (114, 116) ; et une unité d'évaluation (204) qui est conçue pour déterminer, sur la base du signal de contrôle, si un contact électroconducteur est formé entre les conducteurs de charge (114, 116).
