2025 Tesla Model Y in Charleston, SC
Winter range, charging cost and how far it goes, worked out for Charleston's weather, grid and prices.
Charleston's winters are cool rather than cold: on a typical January day (51°F) a Model Y gets an estimated 262 miles, 5% under its 277-mile rating, about the same as in the coldest week (around January 15, when it averages 51°F). By May it's back to about 290. Charging at home at South Carolina's average rate (15.5¢/kWh) costs about $58 a month for 38 miles a day, about a third of the $186 an average small SUV costs on the Lower Atlantic's gas. And Charleston's grid (SERC Virginia/Carolina), 23% cleaner than the US average, makes it 77% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 139 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 277-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Charleston drivers ask
How far can a Model Y go in a Charleston winter?
About 262 miles on a typical January day (51°F) and about the same in the coldest week of the year (around January 15, 51°F on average), estimated from real EV drives at those temperatures. That's 5% below its 277-mile rating, mostly from heating the cabin and the battery.
How much does it cost to charge a Model Y in Charleston?
About $58 a month at home for 38 miles a day, at South Carolina's average home electricity rate of 15.5¢/kWh: about 5.0¢ a mile. An average small SUV on the Lower Atlantic's average gas ($3.86 a gallon) costs about $186 a month for the same driving.
Can I charge a Model Y on a regular 120 V outlet in Charleston?
At 38 miles a day, yes, all year: a 120 V outlet adds about 45 miles in 12 hours even in Charleston's coldest week, and about 48 on an average day.
Is it greener to drive electric on Charleston's grid?
Yes, more than most places. Charleston's grid (SERC Virginia/Carolina) is 23% cleaner than the US average, so a Model Y charged on it makes 77% less CO₂ than an average small SUV.
