Abstract: 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.

Abstract: Selective efficiency multi-phase traction inverters and chargers as heat sources for thermal conditioning of electric vehicles is provided. The traction inverter comprises a plurality of phases, each of the plurality of phases having at least one semiconductor switching device, the at least one semiconductor switching device configured to switch between at least three differing states, for thermal management of the electric vehicle components and compartments. The traction inverter includes a controller coupled to the plurality of phases, to operate the plurality of phases in a first mode of the traction inverter to drive the electric motor as a traction motor. The controller operates the plurality of phases in a second mode of the traction inverter as a first type of converter. The controller to operate the plurality of phases in a third mode of the traction inverter as a second type of converter.
