How Electric Car Air Conditioners Work

The only source of energy for electric cars is the power source battery pack (EVs). As a result, the goal of electric automobile air conditioners is to chill and warm the atmosphere in the passenger cabin while using minimal energy from the battery.

In 2022, electric vehicles will be in high demand. On the tech aspects, the efficiency of Electric vehicle characteristics in contrast to standard petrol and diesel cars on the market is a major aspect of the issue.

The air conditioner is one of the most significant elements in a car since it is essential in the summer season. You can’t drive in high temperatures if you don’t have air conditioning.

Climate control system for electric vehicles

When building an electric car’s air conditioning system, several aspects must be taken into account. The source of electricity is the first big yet evident variation in climate control among IC-powered automobiles and electric cars. For instance, in Tesla models, which are at the forefront of electric vehicle technology, a compressor that operates with a 400 Volts of electricity which is utilised, which is quite close to the one used in our family refrigerators at our homes. 

The compressor is located in front of the vehicle and is powered by the vehicle’s battery pack, or Storage Battery (ESS) as Tesla refers to it. The Power Storage System is located at the back of the vehicle.The pump in an electric car, like the one in IC automobiles, drives coolant through all the cooling coils and freezes the air before everything reaches the vent. Similarly, the operation of an electric cooling system differs from that of an ic cooling system. Let’s take a closer look at the electric cooling system. 

Electric Cars Air Conditioning Problems

Electric cars are also hampered by extreme heat. According to AAA, driving ranges can be reduced by 17 percent when outdoor temperatures reach 95 fahrenheit and then the climate control is used inside the car. Extreme temperatures do contribute to reduced driving range than increasing our range, but it is the utilisation of the vehicle’s heating, ventilator, and climate control system in such conditions, notably the increased heat will have the largest impact on the battery.

The issue is that, unlike a car with just an internal combustion engine, which can use waste heat to warm the interior, EVs must use their batteries to power the temperature control system.

Less battery power necessitates more charging, which raises the vehicle’s operating costs. According to the AAA report, the usage of heat. 

Precautionary measure

In order to expand their sales market, EV makers will need to find a means to explain the consequences of harsh weather to customers. Owners can assist alleviate the effects of excessive changes in temperature on their vehicles in the meantime, according to AAA. While the automobile is still connected to a charger, take a little time to heat your car before starting your journey or you can precool it, instead of cooling the car when it’s not charging and draining the battery you can do this to save your battery and range of your car. If you’re travelling on a longer journey, make sure to plan for numerous charging breaks so you don’t end up stranded in the middle of the street with a flat battery.

How To Use  Electric Car Air Conditioning Efficiently

Many variables may lower an EV’s total range in the summer, just as they might in the winter, and the reaction is considerably different than gasoline-powered automobiles in many respects. There are various strategies to get your batteries in the best condition possible between excursions to extend your range. We’re going to look at some ideas today that can help you increase your range even while it’s scorching hot outdoors.

 Full charge your battery before you go for enhanced battery life.

Electric cars’ advanced technology needs the use of electricity to function. Processes take place in the automobile even while it is stationary and formally shut off. Battery management is one of the important procedures; if the battery becomes too hot, an active cooling mechanism kicks in to maintain the batteries within its safe functioning limits. Even overnight, this can cause battery drain. The best answer is to keep the automobile charged in between trips. It will not overcharge over the limit you specify, but if necessary, it will consume electricity to run the cooling system.

Avoid charging with different level charges until necessary

Another thing to think about is the charging speed. If you’re going to travel 40 to 60 kilometres tomorrow, a Level 1 charger would be the best to charge overnight and it should be enough to get you through the day. You can deal with a family emergency or heavy traffic. If users recharge their battery too quickly or with too much capacity, it will overheat, causing the battery management system to deplete the battery to cool the battery.

The very first thing to think about is how far you’ll have to travel the next day. An electric car battery’s optimal charging level will be 80%; charging it to 100% can cause it to overheat and make the bms cool the battery. If you’ve a long drive ahead of you, charging to 100% is the ideal approach. Tesla, for example, only allows for an 80 percent charge in most situations, requiring you to enter a certain configuration to reach the full 100 percent in case you need more.


A ‘preconditioning’ setting is available on most new electric vehicles. For a predetermined departure time, the car will prepare everything for you and optimal battery temperature. The car prepares these conditions, including air conditioners to battery temperature, so you can get in and start driving without turning up the air conditioning or keeping the window open to make it seem more comfortable inside. preconditioning systems draw electricity straight from the outlet, ensuring that your car is in top operating condition before you leave, all without exhausting the battery. This increases your driving range and comfort.

Place the vehicle in the shaded area

We’ve all had the unpleasant sensation of getting into something like a warm automobile after it’s been out from the sun all day. The sensation of toaster heat is genuine, and it can cause the automobile battery to overheat. If you can keep it plugged in in a shady location or in the garage, you’ll lessen the requirement again for battery to kick in, as well as the demand for air conditioner as well as other reactive cooling equipment while driving.

Additional passive cooling measures include tinted windows and a sunscreen for the window, both of which reduce such a need to chill the vehicle for convenience.


1) Are electric cars powerful enough to cool cars? 

Yes, electric cars are powerful enough to cool your vehicle like fuel vehicles. 

2) Will electric vehicle range get reduced if Ac is used while driving? 

Yes, the range of the vehicle will get reduced up to a few km if used while driving.

3) Are the above measures really effective in cooling the car? 

Yes, the above methods are scientifically proven to increase the cooling capacity of electric vehicle cars. 

4) Is buying an electric car a wise choice when considering cooling capacity? 

Yes, it will be the right option for people who want to reduce the cost of travelling, electric cars can cool your cars as much as fuel cars so don’t worry about cooling. 


I have seen people complaining about Air conditioning in electric cars, that is because they don’t know how electric cars work towards cooling or heating your car by reducing the range of your car.

We have covered everything about cooling and heating your car without worrying about depleting your battery life.  Air conditioning is very important for cars as in this era the temperature is rising gradually.

So if you want to have a pleasurable journey. Then you should know everything about the functioning of EV and ways to cool your car in other working proven scientific ways.
