2026 Chevrolet Equinox EV in Boise, ID
Winter range, charging cost and how far it goes, worked out for Boise's weather, grid and prices.
Boise's winters are cool rather than cold: on a typical January day (32°F) an Equinox EV gets an estimated 257 miles, 16% under its 307-mile rating, and about 252 in the coldest week (around December 24, when it averages 31°F). By May it's back to about 315. Charging at home at Idaho's average rate (13.7¢/kWh) costs about $54 a month for 38 miles a day, about a third of the $199 a gas Equinox costs on the Rocky Mountains's gas. And Boise's grid (WECC Northwest), 18% cleaner than the US average, makes it 71% less CO₂ than gas.
Partly estimated. 1 of 5 temperature bands are from 86 real drives of this model; the rest come from 1,548 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 307-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Boise drivers ask
How far can an Equinox EV go in a Boise winter?
About 257 miles on a typical January day (32°F) and about 252 in the coldest week of the year (around December 24, 31°F on average), estimated from real EV drives at those temperatures. That's 16–18% below its 307-mile rating, mostly from heating the cabin and the battery. Boise averages 33 days a year below freezing.
How much does it cost to charge an Equinox EV in Boise?
About $54 a month at home for 38 miles a day, at Idaho's average home electricity rate of 13.7¢/kWh: about 4.7¢ a mile. A gas Equinox on the Rocky Mountains's average gas ($4.47 a gallon) costs about $199 a month for the same driving.
Can I charge an Equinox EV on a regular 120 V outlet in Boise?
At 38 miles a day, yes, all year: a 120 V outlet adds about 39 miles in 12 hours even in Boise's coldest week, and about 48 on an average day.
Is it greener to drive electric on Boise's grid?
Yes, more than most places. Boise's grid (WECC Northwest) is 18% cleaner than the US average, so an Equinox EV charged on it makes 71% less CO₂ than a gas Equinox.
