Abstract:
A vehicle includes an electric machine, a battery, an inverter, and a controller. The controller switches the inverter at a switching frequency selected to generate an AC current to heat the battery, adjusts a d-axis current of the electric machine to increase a battery heating power, and adjusts a q-axis current of the electric machine according to the adjusted d-axis current.
