Caution, caution, buddy! - Dane's unfortunate battery toasting attempt
Bad news for electric vehicle (EV) batteries during colder temperatures: their efficiency takes a hit, causing a decrease in electric range during winter months. Manufacturers have taken measures to combat this issue by installing heat pumps that quickly warm up the vehicle and battery, but these often come with an added price tag.
However, a rapid baking method isn't the solution for electric vehicle batteries.
Attention!
Danish police raised a red flag about using such a method to heat up energy cells.
The probable cause of the recent fire in the Danish town of Stenlille, about 80 kilometers from Copenhagen, was likely a toaster placed beneath the front of the vehicle by its owner to warm the battery. Luckily, no injuries were reported.
What we know, what we don't
Unfortunately, few details are available about the specific electric car model involved in the accident, as well as the ownership status of the affected property.

Do yourself a favor and steer clear of unconventional methods when it comes to charging or warming up rechargeable batteries, like EV batteries. Fire departments emphasize the importance of avoiding these risks due to the potential consequences.
As electric cars gain popularity, automobile manufacturers are investing in advanced battery technology, including batteries with improved heat management.
Despite the incident in Stenlille, the electric vehicle market continues to thrive. Numerous models garner interest due to enhanced range and performance.
Additional Insights
Avoiding using a toaster to heat an EV battery is not just a good idea – it's essential for safety reasons. Here's why:
- Risky Business: Toasters aren't designed for battery heating. They can trigger electrical fires, explosions, or overheating due to the high voltage and current present in EV batteries.
- Battery Damage: EV batteries need precise temperature regulation to maintain their performance and lifespan. Overheating with a toaster may result in uneven heating, leading to thermal runaway or battery damage.
- Legal and Ethical Consequences: Attempting to heat an EV battery with a toaster is both illegal and unethical. The safety risks are enormous, and property damage can occur as a result.
Instead, opt for these safer alternatives to protect battery efficiency in cold temperatures:
- Battery Pre-Heating: Modern EVs come with battery pre-heating options, utilizing the car's electrical system to warm the battery before driving. This ensures efficiency and an adequate range in cold weather.
- Smart Charging Practices: Use smart charging strategies during winter, such as monitoring tire pressure, conserving cabin heat, and minimizing energy consumption.
- Microwave Energy Solutions: Researchers are working on microwave energy solutions to enhance EV driving range in both hot and cold weather. They plan to use heat pumps with microwave energy for on-demand heating.
- Regular Maintenance: Regularly check battery health and adhere to the manufacturer's guidelines for maintenance. This will help alleviate the effects of cold weather on EV batteries.
