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: 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.

Abstract: Simultaneous fuelling and electrical charging of a plug-in electric hybrid vehicle (PHEV) is inhibited by detecting pre-charging electrical continuity between an on-board charger of the vehicle and a charging plug engaging the charger, and impeding opening of a door controlling access to a fueling port if the pre-charging electrical continuity exist. Simultaneous fuelling and electrical charging of a PHEV may further be inhibited by detecting whether a fuel door of the vehicle is in a fueling-permitting condition and, if the fuel door is in the fueling-permitting condition, preventing an on-board charger engaged with a charging plug from receiving charging current from the charging plug.
