Winter range, charging cost and how far it goes, worked out for St. Louis's weather, grid and prices.

Questions St. Louis drivers ask
How far can an Equinox EV go in a St. Louis winter?
About 256 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. That's 16% below its 307-mile rating, mostly from heating the cabin and the battery. St. Louis averages 13 days a year below freezing.
How much does it cost to charge an Equinox EV in St. Louis?
About $63 a month at home for 38 miles a day, at Missouri's average home electricity rate of 16.1¢/kWh: about 5.5¢ a mile. A gas Equinox on the Midwest's average gas ($4.14 a gallon) costs about $184 a month for the same driving.
Can I charge an Equinox EV on a regular 120 V outlet in St. Louis?
At 38 miles a day, yes, all year: a 120 V outlet adds about 40 miles in 12 hours even in St. Louis's coldest week, and about 48 on an average day.
Is it greener to drive electric on St. Louis's grid?
Yes. St. Louis's grid (SERC Midwest) is 62% dirtier than the US average, but an Equinox EV charged on it still makes 44% less CO₂ than a gas Equinox.
