Industry jargon

A/C

Glossary A/C A/C means air conditioning, the vehicle system used to cool and dehumidify the cabin. In an EV, climate control is powered from the electrical energy available to the vehicle rather than by mechanically driving a compressor from an engine. Air-conditioning demand can reduce driving range because it adds to the vehicle's energy consumption. A/C should not be confused with AC, meaning alternating current in electrical engineering.
