Claim 19:
20. A battery charging method, comprising:
receiving power from a charging station by wire using a charge port;
electrically connecting a battery with the charge port via first and second electrical conductors;
by an inverter module, receiving power from the battery and outputting power to via outputs of the inverter module to U, V, and W phases of an electric motor, the electric motor including stator coils, and the outputs configured to output positive reference potentials to the electric motor; and
by a switch, electrically connecting and disconnecting a first end of a third electrical conductor to and from the first electrical conductor,
wherein the third electrical conductor includes a second end that is directly connected to the U phase of the electric motor and one of the outputs of the inverter module.
