35 BEST Tips How Does AC Work in an Electric Car (Facts)

Electric cars have become increasingly popular over the last few years, and with that comes a lot of questions about how they work.

One of the most common questions is how does air conditioning work in an electric car?

The air conditioning system in an electric car works similarly to the one in a traditional gasoline-powered vehicle. A small electric motor engages the compressor, just like the engine's power would normally do in a conventional automobile.

Once this process is engaged, it pushes refrigerant through a chilling unit and cools the air before reaching the AC vents inside the vehicle. This process is powered by energy from the car’s battery, which means that running your AC will reduce your range slightly.

The Three Phases of Air Conditioning in an Electric Car

The air conditioning system in an electric car has three phases: an electric compressor, a three-phase inverter, and a cooling loop. The compressor takes power from the Energy Storage System (ESS) located at the back of the vehicle and disperses chilled air through the vents.

The three-phase inverter converts direct current drawn from the battery into alternating current for powering up all electrical components including AC compressors.

Finally, there is a cooling loop which circulates ethylene glycol coolant throughout all parts of the vehicle to keep it at optimal temperature levels.

How Does Climate Control Affect EV Range?

Heating or air conditioning can have a big impact on an electric vehicle’s range because it uses up energy from its battery pack.

When you turn on your AC or heater, more electricity is being used to power those systems than when you are simply driving without them activated.

This means that if you plan on taking long trips with your EV, you should be aware of how much energy these climate control systems are using up so that you can plan accordingly and make sure you have enough charge left to get where you need to go!

Your Request: Explain how the electric compressor works 

The electric compressor in an electric car's air conditioning system is the device that compresses the refrigerant to increase its temperature and pressure.

The electric compressor is powered by the vehicle's battery and is designed to function in a similar fashion to a traditional engine-driven compressor.

When the AC system is activated, the electric compressor is powered on and it draws a small amount of energy from the battery to engage the compressor pulley. The compressor then circulates a specific refrigerant (such as R1234yf) around the system to absorb heat from the cabin air into the refrigerant.

The electric compressor has a DC electric motor that drives a swash plate, which in turn drives a variable displacement piston. The piston moves up and down inside a cylinder to compress the refrigerant which raises its temperature and pressure.

The high-pressure, high-temperature refrigerant then flows through a compressed hose to the condenser where it is cooled by air flowing over the fins. Then, the refrigerant flows through an expansion valve where it is converted back into a low-pressure, low-temperature gas.

Finally, the refrigerant circulates through the evaporator, where it absorbs the heat from the car's cabin and cools the air before it's distributed through the AC vents. The whole process is controlled by the AC system's controller, which adjusts the refrigerant flow rate and compressor speed to maintain the desired temperature and humidity level in the cabin.

In summary, the electric compressor in an electric car's air conditioning system works by compressing the refrigerant, raising its temperature and pressure, and circulating it through the system to cool the air in the cabin.

It's an essential component of an electric car's AC system that helps keep passengers comfortable and cool during hot weather while minimizing the system's impact on battery life.

What is the three-phase inverter and how does it work? 

The three-phase inverter is a crucial component of an electric car's air conditioning system that converts the direct current (DC) drawn from the battery to alternating current (AC) for powering up all electrical components, including the electric compressor.

In an electric vehicle, power from the battery flows in a single direction, which means it is DC electricity. However, electric compressors require AC electricity to operate. The three-phase inverter solves this problem by converting the DC power from the battery to AC power that can be used to power the electric compressor and other components in the AC system.

The three-phase inverter consists of electronic components that can switch the DC voltage back and forth across a set of three power outputs at a rate of 50 to 60 times per second. This alternating current is then passed on to the electric compressor and other electrical components, which require AC power to operate.

The inverter also controls the speed and torque of the electric compressor, which helps to optimize the AC system's performance and reduce energy consumption.

The inverter is controlled by the AC system's controller, which constantly monitors the temperature and humidity levels in the cabin and adjusts the inverter's output to maintain a comfortable environment. In addition to powering the AC system, the three-phase inverter also powers other electrical components in the car, such as the complementing battery, traction motor, and electric power steering.

In summary, the three-phase inverter is a critical component of an electric car's air conditioning system that converts the DC power from the battery to AC power that's needed to power up the electric compressor and other electrical components.

This component contributes to the efficient operation of the AC system and helps to conserve the energy stored in the battery.

Your Request: Can you give more details about the cooling loop? 

The cooling loop is a key component of an electric car's air conditioning system that circulates ethylene glycol coolant throughout all parts of the vehicle to keep it at optimal temperature levels. The cooling loop consists of a network of pipes, hoses, and radiators that work together to manage the engine temperature.

The coolant from the cooling loop is circulated through the AC system to absorb the heat generated by the electric compressor and other components in the AC system. This heat is then transferred to the radiator at the front of the vehicle by circulating the coolant through the condenser located in front of the radiator, where it is cooled by the air flowing over the condenser fins.

The cooled coolant then circulates back through the cooling system to the compressor and evaporator to absorb more heat, and the cycle is repeated. The radiator, located at the front of the vehicle, is cooled by airflow as the vehicle moves through space which allows it to cool down sufficiently.

The cooling loop plays an essential role in managing the temperature of electric vehicles by keeping the battery, electric motor, and other critical components at an optimal operating temperature. A well-designed cooling loop is essential for electric vehicles as high temperatures can damage the battery and other components in the drivetrain.

In summary, the cooling loop is an integral component of an electric vehicle's air conditioning system that manages the temperature of the vehicle by circulating coolant through the AC system, battery and electric motor to absorb heat and then dissipating it through the radiator.

This ensures that the vehicle and its components operate optimally and helps to prolong the lifespan of the vehicle.

How does climate control affect EV range? 

Climate control has a significant impact on the range of an electric vehicle. Both heating and air conditioning consume energy from the battery, which results in reduced range. The amount of energy consumed depends on several factors, including the temperature outside, the desired temperature inside the cabin, and the duration of use.

When an electric vehicle's climate control system is turned on, it draws energy from the battery to heat or cool the cabin. This can cause the battery to discharge faster, reducing the potential range. In cold weather, the climate control system will use more energy to heat the cabin and battery, which further impacts the range. Similarly, during hot weather, the AC system requires more energy to cool the cabin, which also drains the battery faster, thus affecting the range.

Research has shown that using an electric vehicle's climate control system can significantly reduce its range. For example, it has been reported that using the heater in an electric vehicle can reduce the range by up to 50%. Similarly, running the AC system can reduce the range by up to 30%.

To maximize the range of an electric vehicle, it is advisable to minimize the use of climate control as much as possible. In cold weather, preheating the car while it is still plugged in and in the comfort of a garage can help extend the battery life. In hot weather, parking the car in a shaded area or using a sunshade can help keep the temperature down in the cabin, which then reduces the amount of energy needed to cool it.

In conclusion, using an electric vehicle's climate control system has a significant impact on its range due to the energy consumption required to maintain a comfortable temperature in the cabin. Taking steps to manage temperature while driving, using seat warmers instead of the heater as much as possible or switching to eco mode may help reduce the impact of climate control on the vehicle's range.
