At the U.S. average residential rate (16.9¢/kWh), a full home charge of the GMC Hummer EV (205 kWh, ~314 mi range) costs about $38.49 — 11.7¢ per mile. Public DC fast charging at ~43¢/kWh runs about $88.15 per full charge.

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

On a Level 2 home charger the GMC Hummer EV accepts up to 19.2 kW, so an empty-to-full charge takes about 12 hours (roughly 28 miles of range per hour). At a DC fast charger its ~350 kW peak gives a 10–80% charge in about 38 minutes. On a standard 120V outlet (Level 1), a full charge takes around 172 hours.

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

Any Level 2 (240V) charger works; the GMC Hummer 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: $38.49 per full charge at the national-average rate.

Living with a GMC Hummer EV: the cost story

The Hummer EV is the least efficient vehicle in our database — a three-plus-ton statement piece whose per-mile cost approaches what a decent gas sedan pays for fuel. Nobody buys it for the economics.

Credit where due: the 800-volt split pack takes on energy impressively fast, and off-road party tricks like CrabWalk are unique. Just know the meter will spin like nothing else on this site.

GMC Hummer EV charging speed & home charger

Cost does not depend on speed — a kWh is a kWh — but time does. These estimates use the GMC Hummer 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 Hummer 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 221 miles, more than most daily driving. See Level 1 vs Level 2 and how many kWh it takes to charge an EV.
