A vehicle apparatus comprising a battery charger is provided. The battery charger is operably coupled to a power grid to receive AC energy during a vehicle charging operation and is operably coupled to a switching circuit for one of connecting and disconnecting the battery in the vehicle. The switching circuit includes a single resistor and is arranged to enable a pre-charge operation and a battery heating operation. The battery charger is configured to convert the AC energy into DC energy for delivering at least a portion of the DC energy to the single resistor for performing the battery heating operation when the vehicle charging operation is being performed.
