| description | 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. |
