Tesla patents selective heat-suction cooling to extend range without adding battery capacity

Tesla has disclosed a patent for a new cabin climate-control technology that selectively draws in hot air from specific zones to improve cooling efficiency. The system adds a suction function to existing HVAC equipment, creating negative pressure at certain points to pull in hot air and recirculate it after adjustment. The patent says it could cut air-conditioning power use by up to 7.4 percent at about 40 degrees Celsius and proposes activating the feature only when needed.
