How does an electric car air conditioning system work?
How does a Tesla's air conditioning work?
- It sits at the front of the car and draws power from the car's battery pack or Energy Storage System (ESS) in Tesla terms, which is located at the rear. The compressor, like in your IC engine-powered car, pushes the refrigerant through the chilling unit and cools the air before reaching the AC vent. The heater system is a little more complicated.
How do electric cars heat the cabin?
- An electric vehicle is approx 80% energy efficient meaning there is some waste heat available from the power electronics, the motor and battery pack. In production Evs most of these parts have a liquid coolant system so cabin heating can be plumbed in exactly like a conventional car heater system and/or into climate controlled seats.
How does the heater work in a car?
- The heater system is a little more complicated. In cars powered by an IC engine, the heating system draws heat from the engine's coolant. Around 30 per cent of the heat generated during combustion is transferred to the coolant, giving a ready heat source.
