How Does the Air Conditioning System in an Electric Car Work?
2 Answers
The working principle of an electric car's air conditioning system is: based on the signals detected by various sensors regarding the cabin temperature, evaporator temperature, engine coolant temperature, and other relevant switch outputs, it controls the operational states of the radiator fan, condenser fan, compressor clutch, blower motor, and air control motor to achieve automatic regulation of the cabin temperature. An electric car refers to a vehicle powered by an onboard power source, with wheels driven by an electric motor. They can be categorized into: 1. Pure electric vehicles; 2. Hybrid electric vehicles; 3. Fuel cell vehicles. The characteristics of electric cars include: 1. Pollution-free and low noise; 2. High energy efficiency; 3. Simple structure and easy maintenance.
I've been driving electric vehicles for several years, and the air conditioning is particularly refreshing. The principle is actually very similar to that of a household split air conditioner. The compressor is directly powered by the vehicle's battery, unlike traditional gasoline cars that rely on the engine to drive it. The refrigerant is compressed, flows through the condenser to dissipate heat and cool down, then passes through the expansion valve into the evaporator to absorb heat, and the air becomes cool when blown over it. The whole process reacts super fast—cold air comes as soon as you press the button, so there's no worry about delays in summer driving. The advantage of the electric compressor is that it consumes less power and operates more quietly. It doesn’t affect the range during long-distance driving and even comes with intelligent temperature adjustment. I often experience its efficiency in city traffic jams, feeling much more comfortable than with gasoline car air conditioning.
