Electric compressor, like a home aircon unit.
With a 0.9kWh NiMH battery (usable capacity about half that), the Yaris hybrid gets about 5-10 minutes of aircon before the engine kicks in. The engine runs for maybe a minute and then turns off again.

7.5kW, although I expect newer ones are less powerful.HomeOwnersHub website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
