An on-board charger (OBC) for an electric vehicle includes a charge unit, a controller, and a control pilot (CP) wake-up circuit. The charge unit is operable for receiving energy from an EVSE for charging a traction battery of the vehicle. The controller while awake can control the charge unit to charge the battery with energy from the EVSE. The CP wake-up circuit receives a control pilot (CP) signal from the EVSE, detects for a change in a current state of the CP signal while the controller is asleep, and generates a wake-up signal for waking up the controller in response to the current state of the CP signal changing to a new state. The CP wake-up circuit includes first/second detector circuits usable for detecting for a change in the current state of the CP signal to a first/second new state.
