How Fast Can I Charge The GMC HUMMER EV In Just 15 Minutes? The Answer Is Surprising!

why would you start the charge at 53 % start it at 10% or 5% if you want to see the charge speed

The 100mi estimate is most likely at a lower soc since the batteries charge faster at a lower % and start slowing down as they get full.

As others have said, a SOC between 5 and 10% and a fully preconditioned battery in ideal climate (60-70 degrees) will net you the ideal charging rate.

Typically the highest charging speed is achieved when the battery is at less than 20% or so, depending on the car. From a certain point it'll start slowing down so starting the charge at 50% is not a good idea to test the charge speed.

Imagine if additional demand were present and everyone wanted to charge, you'd be sitting there for 2 hours

This vehicle is not a cost cutting electric vehicle.

Check to be sure you’re on a 500amp capable station. EA has derated a lot of their 350kw units to 350amps due to equipment issues… thus these high power 400v and 800v cars will never be able to pull max speed regardless of ratings. In addition to achieving said higher speeds at lower states of charge, of course.

0:39 I love that GMC didn’t leave out the automatic door lock feature on the Hummer EV twins as well. I love that feature on my Impala. Just walk away - small but actually very convenient.

I just watched a video that featured a new EV Hummer that was at 4%, when plugged in to home electric, it estimated 4 days until fully charged. Pretty handy.

Will be interesting to see a more complete charging cycle from a low SoC to, say, 80 or 90%

$15.00 for a 20 min charge to go 80 miles????

The cost is getting insane...it is the same cost per mile as my Ford Raptor at $4/gallon of gas...home charging in my area cuts that down tremendously but it is pretty ridiculous.

2:36 Okay, so you started the charge at over 50%, which is not going to give you very good numbers, and the HUMMER EV is unlikely to reach its peak at that battery percentage, even if the battery is conditioned.

I filled my tank with diesel in under 3 mins, I'm good for 400 miles. Bonus, i feed the plants and trees along the way 😎

This makes me super excited to go get 2 diesel trucks and have them for the rest of my life

Just an absolutely excellent informative video. Please do a few more charging videos.

Interesting video with a focus on the speed but what about the expense? $14 for 78 miles of range? At $4/gallon and 20mpg you'd have only spent $16 for basically the same range, and would have been in and out in 5 minutes with a full tank. Personally I value my time at more than $2/hr. And of course this is before the government achieves critical electric vehicle mass and starts levying comparable taxes on electricity as they do for gas (California is already partially doing this). At which point you'll have price parity or worse. And let's not forget the cost of entry here at over $100k. I don't get it.

350 kW will probably only happen if your charge <20%

Good to know that the charging speed from over 50% state of charge is decent for the Ultium platform. This should be the same battery as in the Chevy Silverado EV I ordered, but the Chev is a bit more efficient.

Thanks for the review. Quick calculation in my head, this is still much cheaper to power than my 2021 Raptor on 37s. I get 13.5 mpg. Just paid $4.35 per gallon. So it cost me $25.13 to go 78 miles vs $14.25 in Hummer. And the Hummer is much faster. Great information. Also much cheaper to charge at home, I pay about $0.15 per kWh at home. So about half price to drive around town vs road trips.
