Slate truck in Baltimore, MD
Winter range, charging cost and how far it goes, worked out for Baltimore's weather, grid and prices.
Baltimore's winters are cool rather than cold: on a typical January day (37°F) a Slate gets an estimated 182 miles, 11% under its 205-mile rating, about the same as in the coldest week (around January 15, when it averages 37°F). By April it's back to about 202. Charging at home at Maryland's average rate (21.4¢/kWh) costs about $79 a month for 38 miles a day, against $192 for a gas Ford Maverick on the Central Atlantic's gas. And Baltimore's grid (RFC East), 22% cleaner than the US average, makes it 75% 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 Baltimore drivers ask
How far can a Slate go in a Baltimore winter?
About 182 miles on a typical January day (37°F) and about the same in the coldest week of the year (around January 15, 37°F on average), estimated from real EV drives at those temperatures. That's 11% below its 205-mile rating, mostly from heating the cabin and the battery.

About $79 a month at home for 38 miles a day, at Maryland's average home electricity rate of 21.4¢/kWh: about 6.8¢ a mile. A gas Ford Maverick on the Central Atlantic's average gas ($4.31 a gallon) costs about $192 a month for the same driving.
Can I charge a Slate on a regular 120 V outlet in Baltimore?
At 38 miles a day, yes, all year: a 120 V outlet adds about 45 miles in 12 hours even in Baltimore's coldest week, and about 50 on an average day.
Is it greener to drive electric on Baltimore's grid?
Yes, more than most places. Baltimore's grid (RFC East) is 22% cleaner than the US average, so a Slate charged on it makes 75% less CO₂ than a gas Ford Maverick.
