Questions Hartford drivers ask
How far can a Slate go in a Hartford winter?
About 163 miles on a typical January day (29°F) and about the same in the coldest week of the year (around January 21, 28°F on average), estimated from real EV drives at those temperatures. That's 20% below its 205-mile rating, mostly from heating the cabin and the battery. Hartford averages 60 days a year below freezing.
How much does it cost to charge a Slate in Hartford?
About $92 a month at home for 38 miles a day, at Connecticut's average home electricity rate of 24.2¢/kWh: about 8.0¢ a mile. A gas Ford Maverick on New England's average gas ($4.25 a gallon) costs about $189 a month for the same driving.
Can I charge a Slate on a regular 120 V outlet in Hartford?
At 38 miles a day, yes, all year: a 120 V outlet adds about 40 miles in 12 hours even in Hartford's coldest week, and about 49 on an average day.
Is it greener to drive electric on Hartford's grid?
Yes, more than most places. Hartford's grid (NPCC New England) is 30% cleaner than the US average, so a Slate charged on it makes 76% less CO₂ than a gas Ford Maverick.
