All those electric cords aren't for charging electric vehicles, they're for keeping the engines warm enough that they'll start when it gets very cold. Depending on the owner's preference, a vehicle may just have a block heater that warms the water, or that plus an electric blanket around the battery, and/or electric blankets on the oil pan and transmission. Some people warm their vehicle interiors as well, but that gets very expensive.
