An ultra low cost electric vehicle heating apparatus, components thereof, and related method are herein described. A driver circuit operates a switching device at an intermediate state between fully-turned-off and fully-turned-on, in a high power dissipation heating mode, to efficiently produce heat energy for heating a passenger compartment, or energy storage system, of an electric vehicle. The driver circuit operates the switching device to have a fully-turned-off state and a fully-turned-on state in a main function mode for a traction inverter or an energy storage system charger of the electric vehicle. The driver circuit is operable to cycle the heating mode and the main function mode for combining such heating and such main function operation of the traction inverter, or the charger, without compromising the operation of the traction motor, or charger, while simultaneously eliminating many of the expensive resistive heating components in use by practitioners of the art.
