How much does it cost to charge a GMC Sierra EV?

At the U.S. average residential rate (16.9¢/kWh), a full home charge of the GMC Sierra EV (170 kWh, ~440 mi range) costs about $31.92 — 7.8¢ per mile. Public DC fast charging at ~43¢/kWh runs about $73.10 per full charge.

How long does it take to charge a GMC Sierra EV?

On a Level 2 home charger the GMC Sierra EV accepts up to 19.2 kW, so an empty-to-full charge takes about 9.8 hours (roughly 41 miles of range per hour). At a DC fast charger its ~350 kW peak gives a 10–80% charge in about 31 minutes. On a standard 120V outlet (Level 1), a full charge takes around 143 hours.

What home charger do I need for a GMC Sierra EV?

Any Level 2 (240V) charger works; the GMC Sierra EV's onboard charger caps AC charging at 19.2 kW, so a 80A unit on a 100A circuit reaches that limit — a more powerful charger will not charge it faster. The electricity cost is the same at any speed: $31.92 per full charge at the national-average rate.

Living with a GMC Sierra EV: the cost story

The Sierra EV is the Silverado EV in nicer clothes — same platform, same giant packs, same fast-for-its-class charging. The Denali trim's price positions it against luxury trucks, where its running costs look even better by comparison.

Like all the full-size electric trucks it lives or dies by home charging: on DC-network pricing alone, its big pack makes road-trip fill-ups genuinely expensive single transactions.

GMC Sierra EV charging speed & home charger

Cost does not depend on speed — a kWh is a kWh — but time does. These estimates use the GMC Sierra EV's onboard AC limit (19.2 kW) and its typical DC fast-charging peak (~350 kW); real sessions taper as the battery fills.

Home charger sizing: the GMC Sierra EV tops out at 19.2 kW on AC, so a 80-amp charger on a 100-amp circuit reaches its limit — a bigger unit adds nothing. Overnight (8 hours) on Level 2 restores about 332 miles, more than most daily driving. See Level 1 vs Level 2 and how many kWh it takes to charge an EV.
