The document discusses how electric vehicle range is affected by cold weather and cabin heating use. It shows data that range decreases by 19% without cabin heat and 40% with maximum heat due to energy use. Graphs also show how auxiliary energy load and range decrease with lower temperatures. The document advocates that electric vehicles can have lower total ownership costs compared to gas vehicles, and fleet optimization software can help lower costs.
