Abstract: A system and method for managing communications with a vehicle wireless charging station include a vehicle having a battery configured for wireless charging and a vehicle computing system having a transceiver and a processor programmed to broadcast a signal by the vehicle computing system using the transceiver to establish a communication link with a vehicle wireless charging station in response to a current vehicle location being within a specified range of a previously authorized vehicle wireless charging station. The system and method may include a vehicle HMI to prompt a user for input to authorize communication with a wireless charging station that is not recognized or that has not been previously authorized. Wireless charging related broadcasts may be inhibited when the vehicle is not within a specified range of a known wireless charging station location to conserve energy and reduce potential for unauthorized responses to the vehicle broadcasts.

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.

Abstract: An exemplary reporting method includes the steps of receiving diagnostic data from electric vehicle supply equipment, and then reporting the diagnostic data through an interface of an electrified vehicle. An exemplary electrified vehicle assembly includes a controller of an electrified vehicle. The controller is configured to receive diagnostic data from electric vehicle supply equipment. The exemplary assembly further includes an interface of the electrified vehicle configured to report the diagnostic data.

Abstract: Electric and plug-in hybrid vehicles connect to Electric Vehicle Supply Equipment (EVSE) to recharge a traction battery. Existing standards define the signal interface between the vehicle and EVSE including control pilot and proximity detect signals. The vehicle may use the status of these signals to detect when a connection is established with EVSE. The vehicle may indicate a connection when the signals provide conflicting statuses. The vehicle may prevent driving off and permit charging in the event of a proximity detect signal indicating a state of engagement other than connected as long as a valid control pilot signal is present. The status of the control pilot signal may be utilized to prevent drive-off and permit charging.

Abstract: A vehicle includes a traction battery, an auxiliary battery, a charger, and two DC-DC converters. A first DC-DC converter is connected between the traction battery and the auxiliary battery through a main contactor. A second DC-DC converter is connected between the charger and the auxiliary battery. The charger is configured to charge the auxiliary battery via the second DC-DC converter when the charger is receiving power. The second DC-DC converter is configured to charge the auxiliary battery when the first DC-DC converter is disconnected from the traction battery. The second DC-DC converter can charge the auxiliary battery independent of the charger charging the traction battery. The second DC-DC converter may be configured to generally maximize power conversion efficiency in a range of power outputs associated with charging the auxiliary battery.
