Abstract

Disclosed is a method (600) and a system for determining a welded condition of power contacts (110, 112) in an Outgoing Coil (OGC) within an Electric Vehicle Supply Equipment (EVSE) (102). The method (600) comprises initiating a condition verification process based on a set of predefined conditions. Upon completion of the condition verification process, a voltage pattern recognition process is executed to generate a voltage pattern by superimposing voltage pulses onto a power circuit of the EVSE. The method further comprises capturing an outlet voltage influenced by the voltage pulses superimposed on the power circuit. The method further comprises determining a welding status of the power contacts based on the captured outlet voltage. The method further comprises controlling an operational state of an associated charging outlet of the EVSE based on the determined welding status of the power contacts corresponding thereto.
