"Tesla Charging Woes: Frigid Chicago Exposes Electric Vehicle Challenges"

Extreme cold weather in Chicago caused Tesla electric vehicles to struggle to charge at Supercharger stations, with some owners waiting for hours and experiencing faster battery drain. The cold also affected lithium ion batteries in smartphones and other devices. Tesla recommends keeping the vehicle plugged in and maintaining a charge of at least 20% to cope with extreme cold. The Arctic air is affecting wide sections of the U.S., leading to school closures and dangerous road conditions, with a new surge of cold air expected later in the week.
