Slate Reality Check · Spokane, WA
Slate truck in Spokane, WA
Winter range, charging cost and how far it goes, worked out for Spokane's weather, grid and prices.
Spokane's winters are cool rather than cold: on a typical January day (32°F) a Slate gets an estimated 171 miles, 17% under its 205-mile rating, and about 168 in the coldest week (around December 21, when it averages 31°F). By May it's back to about 202. Charging at home at Washington's average rate (14.7¢/kWh) costs about $56 a month for 38 miles a day, about a third of the $237 a gas Ford Maverick costs on Washington's gas. And Spokane's grid (WECC Northwest), 18% cleaner than the US average, makes it 72% less CO₂ than gas.
Estimated. Almost no one's driving a Slate yet, so these come from 1,548 real drives in other EVs at each temperature (and Recurrent's winter study below freezing), applied to the Slate's rating. They switch to real Slate drives as owners log them.

Questions Spokane drivers ask
How far can a Slate go in a Spokane winter?
About 171 miles on a typical January day (32°F) and about 168 in the coldest week of the year (around December 21, 31°F on average), estimated from real EV drives at those temperatures. That's 17–18% below its 205-mile rating, mostly from heating the cabin and the battery. Spokane averages 41 days a year below freezing.
How much does it cost to charge a Slate in Spokane?
About $56 a month at home for 38 miles a day, at Washington's average home electricity rate of 14.7¢/kWh: about 4.9¢ a mile. A gas Ford Maverick on Washington's average gas ($5.33 a gallon) costs about $237 a month for the same driving.
Can I charge a Slate on a regular 120 V outlet in Spokane?
At 38 miles a day, yes, all year: a 120 V outlet adds about 41 miles in 12 hours even in Spokane's coldest week, and about 49 on an average day.
Is it greener to drive electric on Spokane's grid?
Yes, more than most places. Spokane's grid (WECC Northwest) is 18% cleaner than the US average, so a Slate charged on it makes 72% less CO₂ than a gas Ford Maverick.
