For nearly a week, frigid temperatures from Chicago to northern Texas have made life painful for electric-vehicle owners, with reduced driving range and hours of waiting at charging stations.

In Oak Brook, Illinois, near Chicago, on Monday, television reporters found Teslas that were running out of juice while in long lines for plugs at a Supercharger station. The temperature hit a low of minus 9 Fahrenheit (-23 Celsius).

Outside of Ann Arbor, Michigan, Teslas were plugged in at six of eight charging stations Wednesday as the wind howled with a temperature of 7 degrees Fahrenheit (minus 14 Celsius). At least one driver was nearly out of juice.
