Abstract
A vehicle charging system (10) for an electric vehicle (14) comprises a housing (102) with a DC charging port (108) held by the housing in an internal cavity (134), with a connection end for connecting to the charging device (100) and connected to a power cable (105). The vehicle charging system includes a charge controller (30) for controlling the vehicle charging along the DC charging port. The vehicle charging system includes an arc sensor (34) in the internal cavity, configured to detect an arcing event at the connection end of the DC charging port. The arc sensor includes a light detector (180) with a multimodal diversity detector, configured in a first mode to detect light from the arcing event and in a second mode to detect an arcing noise signature from the arcing event.The arc flash sensor is operationally coupled to the charge controller to control the vehicle charging when an arc flash event is detected.
