A vehicle includes a traction battery, an auxiliary battery, and a charge port configured to mate with a connector of a charging station. The charge port has a pilot pin. A control pilot circuit includes a first switch arranged between the pilot pin and a ground. The pilot circuit further includes a second switch arranged between the pilot pin and the ground. The second switch is configured to close in response to the voltage of the auxiliary battery being less than the threshold to induce the first voltage change in the pilot signal, and open in response to the voltage of the auxiliary battery exceeding the threshold.

Pilot control circuit for charging a vehicle with a charging station

A vehicle includes an Alternating Current (AC) source, a receptacle, and a switch. The AC source has a line and neutral potential. The receptacle is carried by a body of the vehicle and includes line, neutral, and ground conductors, and a ground fault interrupter (GFI) circuit. The switch is coupled between the AC source and the GFI circuit configured to selectively short the neutral and ground conductors.

Dual use vehicular AC generator

A vehicle includes an electric machine, a traction battery to power the electric machine, and a starting, lighting and ignition (SLI) battery. The vehicle also includes a galvanically isolated DC-DC converter connecting the batteries and having a bus capacitance in parallel therewith. The vehicle further includes a contactor to electrically connect the traction battery in parallel with the bus capacitance, and a controller. The controller, in response to a command to close the contactor, activates switches of the DC-DC converter to drive energy from the SLI battery to the bus capacitance before closing the contactor.
