Car air conditioning energy storage

Why do electric vehicles need air conditioning?

The air conditioning (AC) system provides cool, heating and ventilation in the cabin of the electric vehicles (EVs). It is necessary to control the interior thermal environments of the vehicle and ensure safety in visibility. Because AC systems are electrically powered, vehicle range is reduced drastically when the AC system is operating.

Can air conditioning extend the range of vehicles?

This review article discusses the significance and influence of different components of the air conditioning system, and methods followed by researchers to optimize the performance and reduce the energy consumption of the air conditioning system to extend the range of vehicles.

How to reduce power consumption of air conditioning system in electric vehicles?

Based on this review, the following methodologies were identified for the reduction in power consumption of the air conditioning system in an electric vehicle: By utilizing the condensate water, a vaporized moisture presence around the tubes of the condenser can be created to improve the heat transfer rate.

How much energy does a car air conditioner use?

The average energy used by a car’s automotive air conditioning system is around 6% of the total fuel used. The automotive air conditioner is the second largest fossil fuel user after automobile propulsion .

Why does a car air conditioning system use a lot of power?

Power consumption in a car air conditioning system increases due to this effect. The glass surfaces of the car allow the transmission of more heat energy into the cabin. To maintain a clear vision for the driver, the aerodynamic structure, and the appearance of the car, glass surfaces are unavoidable.

How can a battery-powered air conditioning system reduce fuel consumption?

With the help of an effective glazing system, 11.3–48% of power consumption can be saved. A reduction in cooling load of 3.4–20% was reported. During idle/stationary conditions, when a battery-powered motor was used for the air conditioning system, it reduced the fuel consumption by 25–30% in the case of an IC engine vehicle.
