Abstract
A vehicle connected to electric vehicle supply equipment is configured to wake-up an onboard charger based on a pilot signal. A controller is configured to interrupt the pilot signal to prevent the pilot signal from subsequently waking the charger to reduce power consumed by the charger while the vehicle is connected. The interruption may be triggered by a completion of a charge cycle, an extensive charge wait interval, or a charging system condition that prevents charging. The controller may discontinue interruption of the pilot signal in response to a wake-up source other than the pilot signal.
