Abstract

A climate controlling system including an HVAC system and a climate modification subsystem. The HVAC system adds conditioned air into a passenger compartment of an electric vehicle. The HVAC system transmits a signal indicative of its power consumption state. The climate modification subsystem is configured to alter the perceived temperature of a vehicle occupant. The climate modification subsystem transmits a signal indicative of its power consumption state. A controller is connected to the HVAC system and to the subsystem. The controller monitors the signals transmitted by the HVAC system and the subsystem. The controller apportions power between the HVAC system and the subsystem to achieve a minimum combined power consumption state while maintaining a predetermined occupant perceived temperature.
