AC compressor

The AC Compressor in a Tesla is an electrically-driven component responsible for circulating refrigerant throughout the vehicle's climate control system. Unlike traditional engine-driven compressors, Tesla's version operates on high-voltage power from the battery, enabling precise control over cooling and heat pump functions (where equipped). Key functions include maintaining cabin temperature, battery thermal management, and supporting the heat pump system in newer models. It's a critical component for both passenger comfort and battery efficiency, particularly in extreme weather conditions.
