How Does Cold Weather Affect Electric Car Performance?

Electric cars in the United States are becoming more popular every day, and for good reason – they’re efficient, save money on gas, and help reduce emissions. But even with these benefits, some people may still be hesitant to switch to electric cars due to worries about how cold weather might affect their vehicle’s performance.

In this post, we’ll explore how cold weather affects electric car performance and offer tips for keeping your car running smoothly during the colder months.

How Cold Weather Affects Electric Car Performance in the United States

As the weather gets colder, you may notice that your electric car’s battery doesn’t seem to last as long. This is because cold weather can significantly impact electric car batteries, causing them to lose power and range more quickly and slowing their charging.


When the temperature drops, the battery’s chemical reaction slows down, producing less power. This can cause the car to have reduced acceleration and range.

The cold weather can reduce the capacity of electric car batteries by up to 40%. This means that an electric car that can travel 100 miles in warm weather may only be able to travel 70 miles in cold weather.

The colder it gets, the harder it is for the battery to maintain its charge. In extreme cold, the battery may lose power. This can cause range anxiety among drivers, as they worry about being stranded with a dead battery.

This reduced range can be a significant problem for drivers who commute long distances or live in rural areas where charging stations are few and far between.

In fact, it is one of the main reasons electric cars have not been widely adopted in colder climates.


As the temperatures drop, electric car owners may notice that their cars take longer to charge.

The battery in an electric car is made up of many cells that store energy. When it’s cold out, these cells have reduced efficiency and functioning. Therefore, the charging process is slower in cold weather.

Tire Pressure

As the weather gets colder, tire pressure in electric cars can be affected. Cold weather can cause the air inside the tires to contract, which can lead to a decrease in tire pressure. This can impact the car’s performance and make driving more challenging.

The reduced tire pressure will require more juice from your electric vehicle, inevitably impacting the range of your car furthermore.

It is essential to check your tire pressure regularly during the winter months to ensure your car is running correctly. If you notice a decrease in tire pressure, you should inflate the tires to the proper level.


EVs in Alaska also tend to lose range when the temperature drops due to the increased power consumption of their heaters. This can be a problem in areas with freezing weather, as the loss of range can make it challenging to complete a journey.

Does Cold Weather Affect EVs Start?

When it comes to electric vehicles (EVs) in the United States, one of the most frequently asked questions is whether cold weather affects their ability to start. The simple answer is yes; cold weather can have an impact on an EV’s battery and charging system.

However, it’s important to remember that this impact is typically very minor and doesn’t usually present significant problems for EV owners. In fact, EVs are actually designed to perform better in cold weather than traditional gasoline-powered cars regarding starting up!

So, if you’re worried about how your EV will start in the winter months, there’s no need to stress.

How to Improve EV Charging Speed in Winters?

As we know how cold weather affects electric car’s performance, it’s essential to understand how to keep them charged during winter. Below we discuss a few tips to help improve EV charging speed in winters.

Precondition the Battery

Preconditioning is simply bringing the battery up to an optimal temperature before charging.

There are a few different ways to precondition your EV battery:

  1. Plug in and turn on your charger before you park your car. This will help warm up the battery as it charges.
  2. If your EV has a built-in heater, use it to heat the battery before you start charging.
  3. Park your car in a warm garage or other enclosed space before you begin charging.

Doing this will help improve the battery’s charging speed and overall performance in cold weather. So if you’re an EV driver, ensure to precondition your battery before heading out on a cold weather drive.

Time Your Charge

The time of day you charge your electric vehicle (EV) can significantly impact how fast your car charges.

Most people charge their EVs overnight when electricity rates are lower. But if you’re looking for a quick boost during the daytime, there are a few things to keep in mind.

First, consider the temperature. Cold weather can reduce the charging speed of some EVs, so it’s best to charge when it’s warmer out.

Second, check the voltage and amperage of your charger. Higher voltages will charge your EV faster, but make sure your charger can handle the increased power draw.

Finally, try to avoid peak times for electricity usage. Charging during off-peak hours can help you get the fastest charge possible.

Park Your Car in a Garage

If you own an electric vehicle (EV), one of the best things you can do to keep it charged and ready to go is to park it in a garage. While this may seem common sense, many EV owners don’t think about it until they experience problems with their charging speed.

When you park your car outside, the extreme temperatures affect your charging speed. If it’s too hot or too cold, your battery will not charge as quickly.

Parking in a garage will help protect your battery from extreme temperatures and keep it at a consistent temperature. This will allow for faster charging and longer battery life.

So, if you want to charge your EV as quickly as possible, be sure to park it in a garage. It will help keep your charging port clean, protected from the elements, and at a consistent temperature. This will all lead to faster charging times and longer battery life.

Use a Level-2 Charger When Possible

If you’re lucky enough to have access to a Level-2 charger for your electric vehicle (EV), make sure to use it whenever possible! Level-2 chargers can deliver up to 10 times the charging power of a standard Level-1 charger, meaning your EV will charge much faster.

Level-1 chargers are the standard 120-volt outlets found in most homes, while level-2 chargers use 240 volts and can provide up to 19 miles of range per hour of charging. In other words, if your EV has a 24 kWh battery and you’re using a level-2 charger, it will take approximately two hours to charge from empty.

Now, level-1 chargers are fine for most people since they’re easy to find and use. However, if you have the option to upgrade to a level-2 charger, we highly recommend doing so. Here’s why:

Level-2 chargers are much faster. As mentioned above, level-2 chargers can provide up to 19 miles of range per hour of charging, which is significantly faster than the roughly four miles per hour you’ll get from a level-1 charger.

Level-2 chargers are more convenient. If you have a long commute or frequently take road trips, being able to charge your EV quickly and efficiently is a huge convenience. With a level-2 charger, you can charge your EV half the time it would take with a level-1 charger, which means less time spent waiting for your car to charge.

Unfortunately, while level-1 chargers are pretty much ubiquitous, level-2 chargers are still somewhat rare. However, their availability is growing rapidly, and many public places (like shopping malls, parking garages, and office buildings) now offer level-2 charging stations.

How to Improve EV Range in Winters?

When it comes to electric vehicles (EVs), one of the biggest concerns is range anxiety – the fear that the battery will run out of power before reaching the destination. This is a legitimate concern, as EVs typically have shorter ranges than gasoline-powered cars.

However, some steps can be taken to help improve an EV’s range that we discuss below.

Preheat the Car

Preheating the interior of an EV before driving can help to improve range in two ways. First, it warms up the battery, which can help to increase its efficiency.

Second, it reduces the amount of work the heater must do while driving, which also helps to improve efficiency. In both cases, preheating can help increase an EV’s range.

Change Your Driving Style

Your driving style is one of the most significant factors in how far your EV will go on a charge. Here are a few tips to help you get the most range out of your EV:

Avoid Hard Acceleration

Accelerating too quickly can drain your battery faster than gentle acceleration. Instead, try to accelerate gradually whenever possible.

Limit Use of High-power Features

Features like air conditioning and heated seats can draw power from your battery, so using them sparingly can help improve your range.

Drive at a Consistent Speed

Varying your speed uses more energy than driving at a consistent speed. So, if you can keep your speed steady, you’ll likely see an improvement in your range.

Use Cruise Control

Cruise control can help you maintain a consistent speed and reduce energy consumption.

Limit Use of Auxiliary Lights

Using your headlights and turn signals can draw power from your battery. So, if you can avoid using them when possible, it can help improve your range.

These tips can help you get the most out of your EV and improve your range. Of course, other factors can affect your EV’s range (like weather conditions), but driving intelligently is an excellent place to start.

Use Regenerative Braking to the Fullest

Another effective way to improve your electric car’s range in cold weather is to use regenerative braking.

When you brake in an electric car, the motor acts as a generator and produces electricity stored in the battery. This process is called regenerative braking, which can help improve your EV’s range by up to 10%.

To make the most of regenerative braking, you need to know how it works and how to use it properly.

As mentioned earlier, regenerative braking occurs when you brake in an electric car. The motor slows down the wheels while also generating electricity. This electricity is then stored in the battery, which can later be used to power the car.

It would help if you kept a few things in mind when using regenerative braking. First, you need to brake early and smoothly. Sudden stops will not only use up more energy but can also cause the regenerative braking system to overheat.

Second, you must let go of the brake pedal as soon as possible. If you keep your foot on the brake, it will reduce the amount of electricity generated.

Finally, you must ensure your battery is sufficiently charged before using regenerative braking. The regenerative braking system will not work correctly if the battery is too low.

Keep Your Tires Inflated Precisely

One simplest and most effective thing is ensuring your tires are properly inflated. Cold weather causes tire pressure to decrease, leading to a decreased range and reduced fuel economy.

To get the most out of your EV in cold weather, check your tire pressure at least once weekly. You can find your vehicle’s recommended tire pressure in the owner’s manual or your car’s doorjamb.

Once you know the ideal tire pressure, use a tire gauge to check your tire pressure and inflate it as needed.
