A charging system for an electric vehicle comprises a charger connector configured to connect to a charge port on the electric vehicle and includes a housing, a first conductor passing through the housing, a second conductor passing through the housing, and a current sensor configured to sense current flowing through at least one of the first conductor and the second conductor to a battery system of the electric vehicle. A charger-side controller includes an arc fault detection module configured to selectively identify a DC arc fault in response to measured current sensed by the current sensor and to stop charging the electric vehicle in response to detecting the DC arc fault.
