Tesla Troubles in the Chill: A Guide for Electric Vehicle Owners to Avoid Cold Weather Issues
As frigid temperatures grip the United States, certain electric vehicle owners are encountering a harsh reality: Low temperatures have the potential to render their cars inoperable.
This predicament became evident recently when Tesla owners in Chicago found their electric vehicle (EV) batteries had become depleted in sub-zero temperatures.
Furthermore, drivers reported issues with some Tesla charging stations, noting malfunctions or, in cases where they were operational, extended charging times for their vehicles.
Electric vehicles, commonly referred to as EVs, are recognized for experiencing decreased efficiency in colder temperatures.
Cold Weather Impact on Electric Vehicle Range and Battery
Cold weather negatively impacts the efficiency of electric vehicles, as per research conducted by Recurrent, revealing that temperatures below freezing can lead to a reduction in driving range by up to 30% across 18 popular EV models.
Recurrent’s Case pointed out that an EV with a nominal range of 200 to 215 miles might only cover 150 to 175 miles in cold weather.
However, he emphasized that even this diminished mileage is often sufficient for the average driver, considering that most EV users cover an average of 30 miles per day.
In cold temperatures, the chemical and physical reactions occurring within an electric vehicle’s (EV) battery demand additional time, as outlined by Recurrent.
The reduction in temperature hinders these physical processes, consequently diminishing the power accessible to the EV.
Furthermore, unlike vehicles propelled by internal combustion engines, electric vehicles lack the capability to utilize the motor’s heat for warming the vehicle’s interior.
Preventing Electric Car Battery Issues in the Cold
Electric vehicles may experience extended charging times in cold weather, partially due to the fact that most EVs are designed to elevate their battery temperatures when faced with low temperatures, according to Alex Knizek, the Manager of Automotive Testing and Insights at Consumer Reports.
They advocate for warming up the EV’s cabin while the vehicle is connected to a charger and prior to embarking on a drive.
This approach ensures that the car utilizes energy from the grid (charger) to generate warmth rather than relying on the battery itself.
Furthermore, it is advised to precondition the battery before utilizing a DC fast charger.
This process can typically be initiated by directing the navigation system to a DC fast charger or using a designated button that triggers the preconditioning process.
Tesla did not promptly respond to CBS MoneyWatch’s request for comment.
However, the company’s website recommends maintaining the battery charge level above 20% in extremely cold conditions.
Additionally, Tesla acknowledges that energy consumption may rise during such conditions due to increased energy usage for heating both the battery and cabin.
