EV Owners Struggle with Tesla Charging in Cold Weather

What to Know

• Low temperatures slow the chemical reaction within lithium-ion batteries, reducing the efficiency of Tesla charging in cold weather.
• Many EV drivers experience slower charging speeds, reduced range, and longer wait times at Supercharging stations during the winter.
• Using a home charging station, preconditioning your battery, and keeping your vehicle in a heated garage can help reduce the strain of cold temperatures. 
• Hawthorne Auto Square offers a wide selection of EVs and hybrids that perform reliably year-round, keeping Los Angeles drivers on the road no matter the season.

The Science Behind the Struggle: Why EV Batteries Hate the Cold

When temperatures drop, many electric vehicle (EV) drivers report sluggish charging, reduced range, and longer wait times at public charging stations. For Tesla owners in particular, charging in cold weather can be significantly more challenging, causing their vehicles to slow to a halt or stop working altogether. The lithium-ion batteries that power these vehicles don’t perform at their best below freezing, limiting how far you can drive and how quickly your car can power back up. 

In this guide, we’ll break down why Tesla charging slows in cold weather, what you can do about it, and offer tips for finding an EV that runs smoothly year-round.  

Why Is My Tesla Charging So Slowly in Cold Weather?

Cold temperatures slow the chemical reactions within electric vehicle batteries, reducing their ability to accept energy. During charging, lithium ions move from the cathode to the anode to store power. Low temperatures make these ions travel more slowly, reducing the battery’s ability to store energy and forcing the vehicle to charge at a lower speed to protect the battery from damage. 

The American Automobile Association (AAA) found that, on average, EV winter range loss drops by 12% at an ambient temperature of 20°F compared to 75°F. But if you think turning the cabin heater on will help, think again. The increased energy demand from warming the interior can make matters worse, resulting in a 41% decrease in battery range.

Real-World Frustrations: What EV Owners Face at the Supercharger

Cold winter weather can turn a routine charging stop into an hours-long ordeal. Slower charging speeds mean some Tesla drivers spend up to 90 minutes waiting for their car to power up. The chilly temperatures also affect charging cables, connectors, and port latches, making it harder to plug in or start charging. With wait times stretching three to four times longer than normal, crowded Supercharger lines can leave many drivers frustrated and stressed. 

Is This a Tesla Issue or an EV-Wide Problem?

Slow winter charging affects all EVs that use lithium-ion batteries. Cold temperatures slow the chemical reactions within the battery, doubling charge times and making it harder for the vehicle to store energy. 

According to tests by AAA, the following EVs were most affected by cold temperatures. Here’s a look at their range reductions at 20°F (with the HVAC off and with it running):

• BMW I3s: -20.43% / 50.3%
• Tesla Model S 75D: -11.3% / -38.1%
• Chevrolet Bolt: -10.12% / -46.4%
• Nissan Leaf: -10.27% / -31.3%
• Volkswagen 3-Golf: -6.86% / -36.10% 

Winter Charging at Home vs Public Stations

Charging your EV at home during the winter offers a convenient, cost-effective way to skip the long Supercharger lines. Home charging is often the most affordable option, and allows you to precondition the battery and cabin without dealing with slow Tesla Supercharger winter speeds. 

A few other ways you can reduce the impacts of cold weather on your EV include:

• Plugging your EV into a charger as soon as you get home, while it’s still warm.
• Leaving the vehicle in a heated garage or under a car cover to keep the battery warmer than the ambient air.
• In extreme cold, turning on your car’s heater to warm up the inside while it’s charging.
• Knowing the correct tire pressure and checking it often to prevent underfilling and added resistance when you’re driving.
• Never letting the battery charge fall below 20%, as it requires more power just to warm up enough to start charging. 
• Turning on eco-mode to reduce your car’s energy requirements. 

Considering Alternatives or a Tesla Trade-In

Swapping out your Tesla for an EV that performs better in the winter can help you skip the stress of long charge times and reduced range. Many drivers trade in their EVs for hybrid models that include a gas backup to keep you moving on the coldest winter days. Without sole reliance on lithium-ion batteries, these vehicles maintain their performance and require less electric car winter maintenance.

Exploring current listings and talking with the pros at Hawthorne Auto Square can help you determine whether a trade-in or alternative model is the right choice for your winter driving needs.

Frequently Asked Questions

Can cold weather damage my EV?

Cold-weather effects are generally temporary as EV systems regain their original charging and discharging abilities when temperatures warm up. Keeping the vehicle warm, preconditioning your Tesla battery, and avoiding exposure to extreme cold can help minimize the impact.

What’s the ideal temperature range for an EV battery?

The ideal operating temperature for an EV battery is between 68°F and 86°F. However, the temperature at which it’s most efficient depends on the model. 

What if I see steam during Tesla charging in cold weather?

If odorless steam rises from the front of the vehicle during cold-weather charging, it is generally not cause for concern. Some models have a heat pump that produces this steam while charging the battery.
