ABSTRACT:
A series hybrid engine has an electric traction motor drive of the vehicle wheels and a regenerative braking system that converts the motor to a generator for the output of useful electrical energy, the latter being used either to charge the storage battery for a power source for the traction motor, or if the battery is charged, diverting the regenerative energy to a resistive heater located in the cooling circuit of an independently operated accessory driving ICE; the resistive heater providing heat to the coolant to preheat the ICE prior to engine start-up; or, alternatively, or concurrently to supply heat to the core of a heater for the passenger compartment of the vehicle, or, to store the heat in a heat battery type reservoir for future use.
