Can You Run AC While Charging EV?

Yes, you can run the AC while charging an EV. Electric vehicles are becoming more common, and people often wonder how they work during charging. One question that pops up a lot is about using AC while the car is charging. It might sound like a small thing, but it’s good to know how it affects your EV. Keep reading below to know what happens when running the AC while charging the EV:

Power Draw from Battery

When the AC is on, it uses electricity from the car’s battery. While charging, some of the incoming power goes to run the AC instead of fully charging the battery. This means the battery is getting less energy than if the AC were off. It’s a small change, but it can make charging take a bit longer, especially at public spots like EV charging stations in Bangladesh, where drivers may use the AC while waiting.

Slower Charging Speed

Because the AC uses some power, the battery charges more slowly. The charger still works, but the total time to reach full charge increases. How much slower depends on how strong the AC is and how fast the charger works. It’s not a huge delay, but it’s something to keep in mind if you’re in a hurry.

Battery Management System Adjusts

The car’s battery system watches and controls how much power goes where. When the AC is on, it makes sure the power is shared safely between charging and cooling. This helps keep your battery healthy and stops anything from overheating. The system does all this automatically, so you don’t have to worry.

Comfort Maintained

Even if charging slows a little, using the AC keeps you cool and comfortable. This can be really helpful on a hot day or while waiting in your car. You won’t have to choose between staying cool and charging the battery. Just remember, comfort may cost a few extra minutes on the charger.

Energy Efficiency Impact

Running the AC while charging does use more energy overall. It can make your EV slightly less efficient if you use AC a lot. That means a bit more power is used for cooling instead of storing it for driving. It’s not a big issue, but good to know if you’re watching your energy use.

What Functions Can Be Used During EV Charging?

Electric vehicles are smart and packed with useful features. When you plug in your EV to charge, your car doesn’t just sit there doing nothing. You can actually use some helpful functions while it charges. Want to know which ones? Here are the features that continue to function during EV charging:

Air Conditioning or Heater

You can turn on the AC or heater while the car is charging. Most EVs let you turn on EV while charging, so you can stay cool or warm without needing to unplug. This may slow charging just a bit, but it’s totally safe. It keeps you comfortable while the battery fills up.

Charging Status Display

While charging, the car shows how much power is going in. You can see how full the battery is and how much time is left. Some EVs even give you details like how fast it’s charging. This helps you plan your time better. It’s simple but really useful.

Cabin Lights and Screens

Need to find something inside the car at night? No problem — the lights inside still work. You can also turn on interior screens if you want. These don’t use much power and won’t affect charging much. It’s just like sitting in a parked car with the engine off.

Infotainment System

The screen in your car, music system, and apps can all work while charging. You can listen to music, watch videos, or check maps. Some EVs also let you browse the internet or play games. It’s a nice way to pass the time while waiting. You’re basically using the car like a mini entertainment center.

Phone Charging

Most EVs have USB ports or wireless charging pads. So while the car charges, you can charge your phone too. It’s handy if your phone is low and you’re waiting in the car. The phone uses only a small amount of power. It won’t mess with the car’s charging at all.

Climate Control Settings

Many EVs let you set the temperature before you even start driving. While charging, you can pre-cool or preheat the car. That way, it feels just right when you’re ready to go. This uses charging power but doesn’t hurt the battery. It’s a smart way to save time and energy.

How Much Power Does an AC Use During EV Charging?

When you run the AC while charging your EV, it uses extra power. The amount depends on how hot it is and how strong the AC runs. At first, the AC may use more power to cool the car down. Once the cabin is cooler, the power use drops to a lower level.

On average, the AC uses between 1 to 3 kilowatts of power. In very hot weather, it can go up to 6 kilowatts for a short time. This extra power comes from the charger, so charging may slow down a bit. But it’s still safe to use the AC while charging.

If your car is parked in the shade, the AC doesn’t have to work as hard. That means it uses less power and charging stays faster. Using a sunshade or parking under a tree can help keep the car cooler. This way, you stay comfortable without using too much extra energy.

Does Level 1 vs Level 2 EV Charging Make a Difference for AC Use?

Using the AC while your EV charges depends on the charger type. Level 1 and Level 2 chargers supply power at different rates, which affects how much power is left for other functions like AC. Below is a table comparing how Level 1 and Level 2 charging impact AC use:

What Should You Consider Before Using AC During EV Charging?

You might consider using the AC when charging your electric car. It sounds simple, but there are a few things to know before you do it. Using AC while charging can affect the process in small ways. To understand it better, check out the points below and see what matters most.

Charging Speed

When the AC is running, it takes some power from the charger. This means the car might charge more slowly than usual. It’s not a huge delay, but it can add extra time if the battery is low. If you’re in a hurry, turning off the AC can help speed things up. Knowing this helps you plan your charging time better.

Power Source Load

Running AC and charging at the same time puts more load on your home’s power. If your home charging setup isn’t strong enough, it could trip breakers or cause other small issues. Most modern setups can handle it, but it’s good to be sure. Always check your charger and power capacity. A stable setup means a safer and smoother experience.

Battery Usage

While your EV is charging, using the AC means the battery works a bit harder. The car has to manage charging and cooling together. This doesn’t damage the battery, but it can use a bit more energy overall. The car’s system balances this well, but it’s good to know what’s happening. It just means slightly more power is used during charging.

Charging Location

Where you’re charging makes a difference. If you’re charging at home, you usually have more time and comfort. But at a public charging spot, you might want to charge faster and leave. In that case, turning off the AC and finding a charging spot that partners with reliable service providers like Crack Platoon would be a better option. Always think about your location and how much time you’ve got.

Weather Conditions

Hot or cold weather can change how you use the AC. In summer, you’ll probably want the AC on while charging. But in cool weather, you might not need it at all. Using AC in extreme heat can use more energy and slow down charging. Knowing your weather helps you make a smart choice.

Comfort vs. Efficiency

Sometimes, staying comfortable is more important than saving a few minutes. If you’re tired or it’s really hot, using AC makes sense. But if you’re short on time, skipping it can help speed up charging. It’s all about what matters more to you at that moment. Think about whether you need comfort or quicker charging.
