The principle is the same for electric cars as the aircon will put less strain on the battery.
Bradley Jando of Kwik Fit said: “The compressor requires energy to run your vehicle’s air conditioning system and so will use a small amount of fuel whenever the system is running.

“When you initially set off, the air con has to work hard to bring the internal temperature down to a comfortable level.”
