Winter range, charging cost and how far it goes, worked out for Portland's weather, grid and prices.
Winter barely touches range in Portland: at a typical January's 42°F, a Slate gets an estimated 192 miles on a charge, within 7% of its 205-mile rating. Charging at home at Oregon's average rate (16.0¢/kWh) costs about $59 a month for 38 miles a day, about a third of the $223 a gas Ford Maverick costs on the West Coast's gas. And Portland's grid (WECC Northwest), 18% cleaner than the US average, makes it 73% less CO₂ than gas.

Can I charge a Slate on a regular 120 V outlet in Portland?
At 38 miles a day, yes, all year: a 120 V outlet adds about 47 miles in 12 hours even in Portland's coldest week, and about 50 on an average day.
