A method of efficiently heating a passenger cabin of a vehicle includes heating a first fluid using a fluid heater. The first fluid flows through a thermal storage element to transfer thermal energy to the thermal storage element. The heating of the first fluid and the thermal storage element occurs during a recharging of a rechargeable power source used to power the vehicle. During operation of the vehicle and following discontinuation of the recharging of the rechargeable power source, the thermal energy stored to the thermal storage element is transferred to air to be distributed to the passenger cabin of the vehicle by flowing the first fluid through a first heat exchanger in thermal communication with the air to be distributed to the passenger cabin of the vehicle, thereby extending a range of the vehicle.

A hybrid vehicle controller controls a start or a stop of an engine according to a heating requirement or an engine-warming requirement. When at least one of the heating requirement and the engine-warming requirement is generated and a state of charge (SOC) of a main battery is higher than a specified threshold, the controller performs an SOC-fall-control to drop an SOC of a main battery. When the SOC of the main battery falls to a specified value, the engine is restarted. Since the engine can be started in a state where the SOC is lower enough than the upper limit by performing the SOC-fall-control, the engine output power can be converted into the heat for heating the passenger compartment or warming-up the engine. 1.
