• It may price greater than $100 to fill the GMC Hummer EV’s huge battery pack at a fast-charging station.
• We carried out our charging take a look at at an Electrify America station, which prices $0.43 per kilowatt-hour.
• The Hummer maxed out at a formidable 287-kW charging price, second solely to the Lucid Air on this yr’s subject of EV of the 12 months contenders.
Welcome to Automobile and Driver’s Testing Hub, the place we zoom in on the take a look at numbers. We have been pushing automobiles to their limits since 1956 to offer goal information to bolster our subjective impressions (you possibly can see how we take a look at here).
It prices some huge cash to replenish a giant pickup truck’s fuel tank—particularly today. However what if we instructed you that even an electrical pickup truck may crest the $100 mark when it comes time to replenish the battery? That is what we discovered after we plugged the 2022 GMC Hummer EV in for a fast-charge session.
For our charging take a look at, we plugged the Hummer in at an Electrify America station to go from 10 p.c cost to 90 p.c cost. At present charges of $0.43 per kWh, including 80 p.c cost price us $81, together with gross sales tax. Extrapolating from that, to go from 0 p.c to 100% cost at a DC fast-charging station would price over $100. The Hummer did hit a formidable 287-kW peak cost price, second solely to the Lucid Air among the many 20 rivals on this yr’s subject of EV of the Year contenders. However its common between 10 and 90 p.c state of cost was a much less wowing 98 kW and, partially as a result of the pack is so giant, it took an hour an 49 minutes so as to add that 80-percent cost.
Now, you would possibly discover that multiplying the Hummer EV’s whole battery capability of 212.7 kWh by $0.43 does not fairly come to $100. However there are charging losses, as evidenced by our 80 p.c fill that took 177.9 kWh, about 5 p.c greater than what made it into the pack (80 p.c of the overall capability is 170.2 kWh). And our session in Michigan added a 6 p.c gross sales tax, which after all varies by state.
Charging prices may also fluctuate by state, and by charging supplier. However the level stays: though GM has tried to recast the Hummer for the electrified period, that does not imply it is low cost to gas. It’s, in spite of everything, a 9640-pound, 1000-horsepower, four-wheel-drive pickup truck that prices six figures, it doesn’t matter what it is powered by.
