Hummer EV Charging Cost Calculator: What It Really Costs to Charge

This Hummer EV charging cost calculator shows what it costs to charge a GMC Hummer EV Pickup or SUV, per charge, per mile, and per year. The Hummer carries the largest battery in any production vehicle, so the gap between charging at home and charging on a road trip is wider than on almost any other EV. Pick your trim, your charging location, and your electricity rate to see real numbers. For the underlying math on any electric vehicle, see our full EV home charging cost calculator.

Quick answer

A full home charge of a 24-module GMC Hummer EV Pickup costs about $38 to $43 at the US average residential electricity rate, which works out to roughly $0.12 per mile. The same full charge on a Tesla Supercharger or Electrify America runs $90 to $110, closer to $0.26 to $0.30 per mile, about what a thirsty gas truck costs to fuel. The reason is size. The Hummer’s 212.7 kWh usable battery is more than double a typical EV, so every full charge moves a lot of energy. Enter your details below for your own number.

The Cost Drivers

Why the Hummer EV Costs What It Does to Charge

Two numbers set your bill: how much energy the battery holds, and how much energy the truck uses per mile. The Hummer is at the top of the chart on both. Here is what moves your cost, and why home and public charging land so far apart.

🔋212.7 kWh

The Biggest Battery on the Road

The 24-module Hummer EV Pickup 3X holds about 246.8 kWh gross and 212.7 kWh usable, the largest battery pack in any production vehicle. The 20-module pack on the 2X trims and the full SUV lineup holds about 177 kWh usable. A bigger tank means a bigger bill per full charge, even when the cost per mile stays in normal EV range.

📉57.8 kWh

Low Efficiency, per 100 Miles

At about 57.8 kWh per 100 miles in Edmunds testing, the Hummer EV is the least efficient electric vehicle they have measured, using roughly twice the energy per mile of a Tesla Model Y. Efficiency, not battery size, is what sets your cost per mile. It is why a Hummer costs more per mile than a smaller EV on the same electricity rate.

🏠2 to 3x

Home vs Public Charging

Charging at home on the US average rate near $0.18 per kWh is the cheapest option by a wide margin. Public DC fast charging from Tesla or Electrify America runs $0.40 to $0.50 per kWh, so the same energy costs two to three times as much. On a pack this size, that gap is $50 or more on a single charge.

🔌6 to 11%

Charging Losses and the Adapter

Not all the energy you pay for reaches the battery. Home Level 2 charging loses about 11 percent to heat and conversion, while DC fast charging loses about 6 to 7 percent. The 2026 Hummer uses a CCS port, so reaching Tesla Superchargers needs GM’s NACS to CCS adapter, a one time cost of about $225. These losses are already built into the numbers above.

The Math

How the Charging Cost Is Calculated

How is Hummer EV charging cost worked out on this page? The calculator starts with your trim’s usable battery size, adds the energy lost during charging, then multiplies by your electricity rate. Cost per mile uses the same logic against the truck’s real efficiency.

Cost per charge = (Usable kWh × Charge Window ÷ Charging Efficiency) × Rate

Cost per mile = (kWh per mile ÷ Charging Efficiency) × Rate

A full 0 to 100 percent fill of a 24-module Pickup moves 212.7 kWh into the battery. At home you draw about 239 kWh from the wall once the roughly 11 percent charging loss is counted, so at $0.18 per kWh the charge costs close to $43. Cost per mile uses the truck’s rated efficiency, about 0.59 kWh per mile for the 363 mile Pickup, which lands near $0.12 per mile at home. The electricity rate comes from the US Energy Information Administration. Charging efficiency and network rates come from published owner data and network pricing. Winter driving, towing, and off-road use all raise the kWh per mile, which is why cold months cost more. See the Hummer EV range calculator for how conditions change energy use.

Network Pricing

What a Charge Costs on Each Network

The same Hummer costs very different amounts depending on where you plug in. These are full charge figures at each network’s typical rate, with charging losses included. Cost per mile is shown for the 24-module Pickup, and it is similar across trims.

Where You Charge Typical Rate Full Charge, 24-module Full Charge, 20-module Cost per Mile
Home Level 2 $0.18/kWh about $43 about $36 about $0.12
Electrify America (Pass+ member) $0.36/kWh about $82 about $69 about $0.23
Public Level 2 $0.32/kWh about $76 about $64 about $0.21
Tesla Supercharger (via adapter) $0.42/kWh about $95 about $79 about $0.26
EVgo $0.44/kWh about $101 about $84 about $0.28
Electrify America (guest) $0.48/kWh about $110 about $91 about $0.30

Rates vary by state, time of day, and membership. Electrify America’s Pass+ plan lowers the per kWh price for a monthly fee, worth it if you fast charge often. A GM NACS to CCS adapter, about $225, is needed to use Tesla Superchargers with a 2026 Hummer, since it has a CCS port rather than a native NACS inlet.

EV vs Gas

Hummer EV Charging Cost vs a Gas Truck

The Hummer EV is heavy and thirsty for an EV, but it is still compared against full-size gas trucks and SUVs, which are not cheap to fuel either. Here is the yearly cost to drive 12,000 miles, electricity vs gasoline at about $4.20 a gallon.

How It Is Fueled Cost per Mile Yearly Cost, 12,000 mi vs Home Charging
Hummer EV, charged at home about $0.12 about $1,420 baseline, cheapest
Gas truck at 20 mpg about $0.21 about $2,520 about $1,100 more
Gas V8 truck at 16 mpg about $0.26 about $3,150 about $1,730 more
Hummer EV, public DC fast charging about $0.27 about $3,240 about $1,820 more

The pattern is clear. Charged at home, a Hummer EV costs less than half what a 16 mpg gas truck costs to fuel. Lean on public DC fast charging for most of your miles and the advantage disappears, landing close to the cost of running a gas guzzler. The break point is how much you can charge at home.

Cut the Cost

Six Ways to Lower Your Hummer Charging Bill

On a battery this large, small changes in how and where you charge add up fast. These are the highest impact habits for Hummer EV owners, ranked by how much they save.

1
Charge at home whenever you can. This is the single biggest lever. Home charging near $0.18 per kWh costs less than half of public DC fast charging. A 240 volt Level 2 setup and the Hummer’s 19.2 kW onboard charger can add a full pack overnight.
2
Move charging to off-peak hours. Many utilities offer a time of use rate that drops to $0.10 or less overnight. Set the Hummer or your charger to start after the peak window. On a 200 plus kWh pack, that alone can cut a full charge by a third.
3
Join a network plan if you fast charge often. Electrify America’s Pass+ and similar plans lower the per kWh rate for a monthly fee. If you use public DC more than a few times a month, the membership pays for itself on a pack this big.
4
Charge to 80 percent for daily driving. A 10 to 80 percent session is faster, keeps you in the cheaper part of the DC curve, and is easier on the battery. Save the full 100 percent fill for road trip mornings.
5
Precondition and avoid deep cold. Cold weather raises the kWh used per mile, so each mile costs more. Warm the battery while plugged in before you leave, and park in a garage where you can, so you are not paying to heat a cold pack.
6
Add solar or lock a fixed supply rate. Home solar can push the marginal cost of a charge near zero in daylight. If solar is not an option, a fixed rate supply plan protects a big charging budget from rate spikes.

Common Questions

Hummer EV Charging Cost Questions, Answered

At home on the US average rate of about $0.18 per kWh, a full 0 to 100 percent charge costs about $43 for a 24-module Pickup with the 212.7 kWh usable pack, and about $36 for a 20-module truck or SUV with the 177 kWh pack. On a Tesla Supercharger or Electrify America at $0.42 to $0.48 per kWh, that same full charge runs $90 to $110. Charging losses of about 6 to 11 percent are included in these figures.
About $0.12 per mile charged at home, and about $0.26 to $0.30 per mile on public DC fast charging. The Hummer uses roughly 0.55 to 0.60 kWh per mile, which is high for an EV, so its cost per mile is higher than a smaller electric car on the same rate. Even so, home charging keeps it well under the cost of fueling a comparable gas truck.
Charged at home, yes, by a wide margin. About $0.12 per mile at home compares with about $0.26 per mile for a 16 mpg gas truck at $4.20 a gallon, so home charging costs less than half. The picture changes if you rely on public DC fast charging, which at $0.27 per mile lands close to what the gas truck costs. How much you can charge at home is what decides whether the Hummer saves you money.
Home charging is usually two to three times cheaper per kWh than public DC fast charging. A full Hummer Pickup charge is about $43 at home versus $95 to $110 on a Supercharger or Electrify America. On a battery this large, that is a $50 to $70 difference on a single charge, which is why owners are advised to do the majority of their charging at home.
For 12,000 miles a year charged at home, expect about $1,420 a year, or roughly $118 a month. On public DC fast charging that rises to about $3,240 a year. Most owners land in between, doing daily charging at home and using public chargers on trips. Use the calculator above with your own annual mileage and rate for a tailored figure.
A Level 2 charger at home on an off-peak time of use rate is the cheapest by far. Many utilities offer overnight rates of $0.10 per kWh or less, which can bring a full charge under $25. Home solar can push the daytime cost of a charge close to zero. Public DC fast charging is the most expensive option and is best kept for road trips.
On a road trip you are charging on DC fast chargers, so budget about $0.26 to $0.30 per mile. A 10 to 80 percent Supercharger session on a 24-module Pickup adds roughly 150 kWh and costs about $65 to $75 at $0.42 per kWh. Because the Hummer uses a lot of energy per mile, road trip charging is where the running cost is highest. Our road trip calculator adds up stops and cost for a full route.
Yes, with an adapter. The 2026 Hummer EV has a CCS port, not a native NACS inlet, so it needs GM’s approved NACS to CCS adapter, about $225 one time, to use Tesla Superchargers. Once connected, pricing is Tesla’s usual rate, around $0.42 per kWh on average, which makes a full Pickup charge about $95. GM electric vehicles are expected to move to a native NACS port from the 2027 model year.
No. The federal clean vehicle tax credit ended for vehicles acquired after September 30, 2025 under the 2025 budget law, so it is not available for a 2026 purchase. Even before that, the Hummer EV did not qualify, because its price is well above the $80,000 MSRP cap that applied to electric trucks and SUVs. Some state, local, and utility charging incentives may still apply where you live.
Two reasons stack up. The battery is the largest in any production vehicle, so a full fill simply moves more kWh than any other EV, and public DC rates are charged per kWh. On top of that, the Hummer uses more energy per mile than any EV Edmunds has tested. Put a high per kWh rate against a very large, energy hungry pack and the fast charge bill climbs quickly. Charging at home is what keeps the overall cost reasonable.
