Slate Reality Check · St. Louis, MO
Slate truck in St. Louis, MO
Winter range, charging cost and how far it goes, worked out for St. Louis's weather, grid and prices.
St. Louis's winters are cool rather than cold: on a typical January day (32°F) a Slate gets an estimated 171 miles, 16% under its 205-mile rating, about the same as in the coldest week (around January 14, when it averages 32°F). By April it's back to about 201. Charging at home at Missouri's average rate (16.1¢/kWh) costs about $60 a month for 38 miles a day, about a third of the $184 a gas Ford Maverick costs on the Midwest's gas. St. Louis's grid (SERC Midwest) is 62% dirtier than the US average, but charging on it still makes 47% 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.

About 171 miles on a typical January day (32°F) and about the same in the coldest week of the year (around January 14, 32°F on average), estimated from real EV drives at those temperatures.

About $60 a month at home for 38 miles a day, at Missouri's average home electricity rate of 16.1¢/kWh: about 5.2¢ a mile. A gas Ford Maverick on the Midwest's average gas ($4.14 a gallon) costs about $184 a month for the same driving.
Can I charge a Slate on a regular 120 V outlet in St. Louis?
At 38 miles a day, yes, all year: a 120 V outlet adds about 42 miles in 12 hours even in St. Louis's coldest week, and about 50 on an average day.
