    Abstract: An electrified vehicle and method for heating a passenger cabin of an electrified vehicle that may include an internal combustion engine in addition to an electric machine and a traction battery for supplying the electric machine control an electric heating element to store thermal energy while the vehicle is connected to an external power source that is also used to charge the traction battery, and to extract stored thermal energy during operation of the vehicle with the electric heating element turned off to extend the electric driving range of the vehicle while also providing heat to the passenger cabin. The electric heating element may positioned and controlled to heat one or more elements directly by mechanical contact, or indirectly by heating a circulating liquid coolant to a temperature above a current or anticipated external ambient temperature.

    Abstract: A method of starting an engine is disclosed in which two or more starter motors are used to start the engine in an alternating sequence so as to equalize wear and reduce the wear of each starter motor by a factor equal to the number of starter motors provided. The starter motors are preferably positioned so as to minimize overlap between wear patterns produced by the starter motors on a cooperating ring gear 8 thereby extending the life of the ring gear.
