A gigantic battery pack can be found in the GMC Hummer EV, but, when you’re out on the road, it can be a little too expensive to charge. One Hummer EV was charged from zero to 100% on an Electrify America charger by Kyle Conner from Out of Spec Reviews, as covered by InsideEVs. Thanks to a 246 kWh battery with 212 kWh usable capacity, the GMC Hummer EV has a stated range of 329 miles. To fully charge the battery at a 350 kW charging station, it took 2 hours and 32 minutes in the test. As the charger reported a delivery total of 224 kWh of electricity, it suggested charging losses of approximately 5%.
Before taxes and fees, it comes to a total of $96.32 at Electrify America’s standing rates of $0.43/kWh. So when we consider all the factors, that rounds up to over $100 for a full charge. And before taxes for Electrify America Pass+ members, who are only charged $0.31/kWh for a $4 monthly fee, that drops to $69.44, said a report on The Drive.
But Conner somehow managed to score a complimentary charging session and saved himself big money in the process. Some Electrify America stations alternatively charge per minute rather than per unit of electricity consumed. Given rates of $0.32/min and $0.24/min respectively, it is possible to fully charge the Hummer EV for around $50, or $37 for Pass+ members at those stations. Of course, it is assumed that the Hummer EV is charging at full speed on a 350 kW charger.
A cheaper option would be charging at home, as to fully charge the Hummer EV, at the national average electricity rate of $0.13/kWh, would only cost approximately $30. In some states with cheaper rates of $0.07/kWh like Colorado, that gets down to just $16 or so.
So to put it simply, the high cost comes down to the Hummer EV’s gigantic battery. Other EVs mostly sporting over 300 miles of range make do with batteries on the order of 75 to 120 kWh. Kia EV6 and the Tesla Model 3 are very good examples of those. The Hummer EV’s kerb weight of 9,046 lbs simply takes a lot more energy to accelerate all that heft. So basically, it is just not as efficient as other electric vehicles on the market.
In more understandable words, let’s say you pay $100 to travel 329 miles, and at the current national average gas price of $3.76 for regular, that would pay for 26.6 gallons of fuel. Now you divide 329 miles by 26.6 gallons, and you get 12.4 mpg. So the aftermath is that if you are paying the max rate to charge your Hummer EV with Electrify America, you are paying as much as you would be to drive an ancient gas guzzler.
In case you are buying the Hummer EV, you must make a cheap charging plan for it, or just simply charge it at home.
