The recent Arctic air enveloping the United States has presented a predicament for Tesla drivers in Chicago. Many found their cars stuck in lengthy queues at Supercharger stations, struggling with diminished charging efficiency due to the severe cold.

Common challenge for electric vehicles

The issues faced by Tesla owners in frigid temperatures highlight a common challenge for electric vehicles, irrespective of the manufacturer. The culprit is the lithium-ion batteries used in these vehicles, known for their susceptibility to cold conditions, especially below freezing.

Cold’s impact on lithium-ion batteries

The impact of cold on lithium-ion batteries is a familiar experience for anyone who has seen their smartphone’s battery drain rapidly when exposed to freezing temperatures. The same principle applies to electric vehicles, affecting their charging capabilities and overall battery performance.

Tesla’s cold weather best practices

To tackle extreme cold, Tesla recommends specific measures to enhance the charging experience and maintain optimal battery performance. One crucial recommendation is to keep the vehicle plugged in and ensure a minimum charge of at least 20%.

Preparing for charging in extreme cold

In Tesla’s Cold Weather Best Practices guide, the emphasis is on preparing the car for charging in severe cold conditions. Actions like defrosting the car and setting the cabin’s climate before driving not only enhance driver comfort but also contribute to warming the battery.

Optimizing charging conditions

For effective charging in cold weather, Tesla suggests using its Trip Planner to navigate to a charging location at least 30-45 minutes before arrival. This ensures optimal battery temperature and charging conditions. If the drive to the charging spot is shorter, the guide recommends preconditioning the battery before starting the journey.

Unique Tesla considerations in cold weather

Tesla owners face some specific challenges in cold weather, such as the emission of odorless steam during charging. According to Tesla, this is a normal occurrence related to the heat pump on some models and poses no cause for concern.

Addressing door opening challenges

Another unique consideration is the potential difficulty of opening the door on a Model S with a drained battery. In normal circumstances, the car adjusts the windows automatically to facilitate door opening. However, Tesla advises users to always connect to a low-voltage power supply before attempting to open a door with no power to avoid potential window damage.

Widespread cold weather challenges across the US

The recent cold snap is not unique to Chicago, as extreme weather conditions are affecting various parts of the United States. Both the East and West Coasts are witnessing freezing rain, snow, and other winter precipitation. Cities such as Washington, D.C., Baltimore, and New York are bracing for some of the coldest days of the year, while areas like Colorado are grappling with dangerously cold and snowy conditions, leading to highway closures and school shutdowns.

The challenges faced by Tesla drivers in Chicago shed light on the broader issue of electric vehicles’ susceptibility to extreme cold. As the cold weather continues to grip various regions, it becomes crucial for electric vehicle owners, irrespective of the brand, to follow recommended practices to optimize performance and address specific challenges associated with low temperatures.
