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.

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

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.

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

This vehicle is not a cost cutting electric vehicle.

Hummer 78 miles = $14 Lincoln SUV 20 miles per gallon needs 4 gallons = $20 Time spend 3 minutes. Lincoln is still better

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 😎

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.

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.

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.

guys, as an ev channel, this is an incredibly bad take. 350A EA station, starting at 50%, etc etc.

So over $14 for a whopping 78 miles of range!?! All in 18 minutes. I can fill up my Hyundai Sonata Hybrid in about 4 minutes, pay about $40 and get over 500 miles of range. So that Hummer is actually less efficient and more expensive to fill up than my Hybrid. Not impressed.

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.

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

350 kW will probably only happen if your charge

I love how people are skipping over the fact that they are paying MORE then gas now. I can't believe how many people really believed that charging would never be as expensive as gas.

$15 for 78 miles? I’ll pass on that.

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

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.

The main problem here is that you are starting the charge at a way too high SOC.

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.

Dayum. GM hiring video game designers to do their software was a smart move. Those menus and graphical interfaces make the screens in the Mach-E, Model Y, and Polestar 2 look like 1980s Atari.

And in that time I could have filled up my pickup, grabbed something from inside, and been down the road

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.

$14.24 doesn’t seem very cheap to travel only 75 miles

Lowkey 14.25 for 75 miles is almost the same as my Acura gets with the high gas prices and taking premium gas. Full supporter of electric vehicles but I was surprised at the price to charge this one.

The fact the Hummer charged from only half charged to 75% in less than 20 mins is actually pretty impressive since these are usually the *slowest* examples of fast charging rates.

Don’t forget to figure in the cost of your time to hang out with the charger 🔌

78 miles added. Real world usable amount is probably closer to 70. At $14.25/70 miles=$0.203/mile. For comparison, my ‘17 Escalade ESV does 20mpg hand calculated, at $4.50/gallon=$0.225/mile. Over a year of driving 8000 miles for me equals a savings of $176/year. Charging at home would cost about ~1/4 of the $0.31 the DC fast charge cost, at $0.08/Kwh, for a savings of $1381/year or $115/month.

78 Miles in 12 mins is pretty impressive. Let’s compare it to its closest gas truck competitor the RAM TRX, which avg 11mpg (if you’re babying it). At 78 miles that’s about 7 gallons of gas in the TRX. National “premium” gas prices is around $5. So let’s take 7 gallons x $5 would be $35 for the TRX compared to $14.25 for Hummer Ev. $0.31 is pretty expensive compared to home charging which avg $0.10-$0.20 per kwh if you’re on the grid. People who are off grid with solar $0. Also, some charging stations offer 1-3 hours free charging at 6 kwh which isn’t fast but better than having to pay.

Very interesting. Good video. We just did a 1500 mile trip in a Tesla model 3 and observed max charge rates when we started with a battery down at 20% or below. Overall, surprisingly easy and convenient to travel with fast charging.

Actually it takes 24 hours to fully charge in "fast charge", 4 days at home.

If it was summertime and 100° outside, and you just pulled off the highway, how would that affect the charge rate ?

This EV movement is fun to watch and very fascinating. Hopefully within 2-3 generations they have faster charging and more importantly range. Real world range is just where I want it to be to feel confident and comfortable.

The GM Ultium platform seems incredibly promising. Can’t wait to see it on more affordable cars like the Equinox

0:45 That might not actually be the maximum charging speed of the GMC HUMMER EV. More likely, that is due to the equipment's limitation. The HUMMER EV's pack is a double-stacked version of the Cadillac LYRIQ's pack, which has a peak charging speed of 190 kW, so the HUMMER EV's theoretical max charge rate is 380 kW. The problem is, the LYRIQ requires a full 500 A of current to achieve 190 kW, and that amount of current is not currently available on these chargers when operating between 500 V and 1000 V.

I just fueled up my SUV and I'm back on the road by the time you got your phone app connected. Curious... How much weight will it tow?

It’s 2:30 and it says it’ll be fully charged at 3:50, screw that and you still have to pay! I’ll stick with gas.

2:00 Oh, come on, GM! The flap on the Chevrolet Bolt EV's CCS port was by far the best DC pin covering option. This plug cap looks ridiculously difficult to work with.

So $14 to go from ~53% to 75%. That makes a “fill up” from 0 to100% cost over $60…

I wonder how many charging stations they had to stop at before they found one that worked...

Gunna be eating a lot of snacks and having a lot of drinks lol

I'm driving from NC to south FL, my 2020 F-150 get there in 8.5 hours. Hummer EV, 3 days...... yeah no

I have seen ENOUGH videos to KNOW max charging speed is a unicorn 🦄 event

Station is fully capable of 350kW; the battery is not. In fact, NO battery on the market is capable of consistant 350kW charging from 0% to 100%. You did charge at a higher percentage so if you were at say 20% you may see those speeds but only momentarily. The only car that can get remotely close to those speeds for an extended period is the Lucid Air and even then with a 900V battery gets around 300-310kW.

This might be the first car review I’ve seen with a successful session of charging from an EA station. Albeit slow. Public charging other than Tesla is a joke.

O.K.. So, now perform a recharge from 5% to 100% and let us know how many minutes it takes. LOL 😂😂😂😂😂

“Sorry work, you’re gonna have to give me 40 mins to charge my vehicle before I can make it in”

Where's tommy? He's the ev guy. He can tell of experiences charging far better than Andre.

5:39 That's going to be very helpful because right now, EV owners are having to guess whether there is a factor affecting their car's maximum charge or an issue with the charger itself. This will save people a lot of time charger hopping if they aren't seeing the speeds they expect to be seeing.

I regularly get over 1000 mph when charging my M3 at a Tesla Supercharger. Those are only rated for 250 kwh.

The energy cost using that charging station at 31¢/kWh is not much less than the cost of gas. I'm an EV fan, but, there's a reason for the slow adoption rate. The cost differential of a new EV far exceeds the energy savings.

I'd go insane putting up with this random charging bs

175-180 kW at 50% is quite good speed actually. Not many EVs would be able to do that (as seen in Mr.Bjorn Nyland's Channel)

$14.25/78miles = $0.18 per miles. That's more expensive than I thought. No thanks

This makes me super excited for the Silverado EV.

Wow 45.9 kW filled an 82 mile gap in charge. Even with the Hummer EV using some of power to condition or cool the battery during charging, that puts it well under the 2 mile/kWh line. Slurping electrons!! Thank you for the first look, Andre. Good to see the real deal and what its like!

And there's my issue with EV.....in 12 minutes I can have filled my F150 XLT with 36 Gallons that gets me over 500 miles plus get my snacks/drinks and be back on the road. When I can charge an EV to 300+ mile range in 10 minutes or less it makes sense, until then, it's kinda worthless to me.

I noticed in one of the videos that they guys were having an issue with the folding mirrors. I have noticed on my Hummer ED1 that my mirrors only auto fold when I lock the truck from either the remote or by pushing the lock button on the door handle. Hope this helps if they are still trying to figure this out.

I would like to see a gas powered Silverado and a EV Silverado drive across the country leaving the same starting, the same route, and same finish point! LA to NY. Interesting to see what the time taken for said trip, the cost to refuel and recharge, and overall performance.

If it becomes normal to charge EVs at 350 kW or more, I wonder how that will effect (no pun intended) the grid. Is it in needs of upgrades? Maybe not now, but if we say 1/3 of the vehicles on the road is electric 20 years from now, are we making the necessary preparations? 🧐

4 days to charge LOL!

VERY Suspicious that you have to 'calculate' what it cost for charging... 🤔 Also: $14.25/78 mi = $0.18 per mile. Not great. (Ya Ya I Know, "But it's better when you charge overnight at home")

Since some people will be saying that's expensive, you're correct; Electrify America makes money from these sessions, unlike Tesla. Thats why.

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

How is this worth it? You spent over $14 for less than 80 miles of range and it took 12 minutes of charge time. The $0.31/kWh is outrageous!

*I dont like this oversimplification of something which is extremely complex* 😤 😠 😡 1- How Far did you had to travel to reach a 350kw Charger ? 2- What is the Availability of this Chargers ( Currently ) *not in 5 years time* after you sold the car 🤦‍♂️ 3- If there's no 350kw Chargers available ( Most likely ) how long would it take to charge using a Home wall Charger or a 7kw Charger ? . I means if there's something like 10 to 20x 350w chargers this is completely pointless until the infrastructure is there as supposed to being like a (LOTERY) regarding who get's to this 350kw chargers first

Correction to my last comment, I didn’t factor the stupid amount of batteries that GM had to use to make up 300 or so miles of range of this truck. 212KWH battery pack. Least efficient EV ever built

I heard many of Electrify America's 350kW chargers can't charge at that rate. They need an updated module to get to that true 350kW speed. EA is working on replacing those on their chargers.

You want to make a video "how is Hummer Ev charging " and you come with 53% soc ?

I got 2 things out of this - the Hummer EV has battery preconditioning (this is good!) and it functions on Electrify America (I’d hope so, but sometimes new models have issues). $0.31/kWh is totally acceptable for DCFC. This is a joke of a charging test starting at 50+%. Do better, TFL.

From zero to 30 percent it can charge at 350kW. Then 30 to 40 percent is about 250kW. Then after that it settles in around 170kW. I think the throttling factor is the thermal management of the battery system.

Will the grid handle ALL cars being EV? Elon Musk has said that the entire US electrical power requirement could be supplied by one 300x300 mile area of solar panels. I thought "whaaat, no way" so I did the math and it is very conservatively true. Home charging currently is about one third of the charge cost in this video. I believe that it is not emphasized enough that home charging will be the vast majority of all electrical vehicle charging, not roadside charging (I also believe that the convenience of home charging will easily counterbalance the inconvenience of much less frequent roadside charging (not for trucking though, hmm)). Lucky enough, home charging almost always takes place overnight when the grid is not highly used. I haven't but someone should do the math of how much electrical power it would take for all electrical power consumption, including the charging of ALL vehicles being electric, overnight versus the typical overall daytime consumption. The rough math is not actually too hard to do. The current grid at current max use likely has a relatively small buffer to overload. If the calculated overnight factor (including all EVs charging) exceeds the current daytime max then the grid has to be upgraded. I haven't done the math, the factor could be even or it could be 5 or 20 times. If the grid has to be upgraded then you can bet the cost of at home charging will rapidly be increased to likely even more than the current fuel costs. I highly suspect that reduced cost to the consumer will NOT ultimately be a benefit for EV conversion but more likely will be justification by the powers that be to increase the "fuel" cost of vehicle travel! Someone has to do that math.

Your videos have convinced me to go look at the hummer over a Cybertruck. The charging was my biggest issue. The US has to do better for other vehicles. Tesla owns the market in this and I’d like to be fully electric but not fully Tesla. I love my X but mainly for the FSD. This charging system is great tho.

could have filled up 20 gas powered cars in this time, these ev's are a joke!

350,000 watts per hour 350kw. That's a shit load of electricity. It's going to add more to your electric bill then it would with filling up gasoline. Once you past 2 or 3 tier electric rates then double and triple in price per Kw.

15 minutes charge is like filling an 18 wheeler truck gas tank 🛻

Wait till those government taxes/fees/electricity price increases kick in. So at $14 you got about a 100 miles. That's roughly 3.25 gallons of gas where I live, my vehicle gets 30 mpg . 3.25x30= 98.5 miles. Savings?

Loving this new channel. Keep up the good work Andre, and everyone at TFL.

I want to see the cost when charging from 50 percent to 100%. I know most lithium batteries take way more energy to get the final 25 %.

Something about monthly subscriptions don’t sit well with me when it come town owning a car and driving. Can I be blocked out of charging my car?

so if your getting 20mpg it's about the same cost to fill

So the cost to charge would be $14.24 for 78miles or $28.48 for 156miles or $42.72 for 234miles

This thing is expensive to charge, but think about a gas version that would get like 10mpg. You would need $120 or more of fuel to go 300 miles. Approximately $60 of electricity at that rate.

14 dollars for 70 something miles? And it's that slow with only one vehicle using the charging station? And yet the clown secretary of transportation suggested everyone change to EV to avoid high gas prices. Bruh...

New to this I don't see these charging stations everywhere so can you just charge at home? What do you do in a camping situation?

Andre : I drive 71 miles each day for six day a week. Spent $60 dollars in gas every week with either my 2 trucks. How much I am going to spend each week charging the Hummer EV ???

Come on TFL, starting a fast charge session at that SOC, is just silly... and you know it...

I just calculated the cost for me to go 78 miles in my Volkswagen Jetta Tdi Sportwagen on bio-diesel that I made myself from used vegetable oil was free.

Why so in his face with the camera? Are we going up his nose? Love the content but god damn.

Its great you can use chargers at the places you are visiting for more than couple hrs or so. But if you going to make a quick pit stop to charge for a few miles to you destination, thats the question I would like to know. Gas its like 5-7 mins fill and you're off. Don't worry about filling up until the tank is 1/4 tank or close to empty. I would rather get a Hummer Hybrid with a V8.

More proof that will push me to buy gas powered with my next purchase.

What kind of whr/mile or miles per kWh is the hummer getting? Because it weighs so much it doesn’t have to be rated by the EPA. Therefore, no one really knows how inefficient this thing really is.

Amazing how much energy it takes to go down the road. We use an average of 30kwh per day in our house!!! lol

Ehh I’ll just wait another 4 years for the cybertruck release

My Ford Eco boost gets 31mpg, which only costs my $7.95 do drive the same 78 miles you just paid $14.20 for. Gas here in Denver is $3.18.

ABB chargers definitely seem to be the most reliable of the manufacturers that Electrify America is using

This charging test does not bode well for the GM Hummer EV. I don't know what GM was thinking taking their most inefficient vehicle of all time and deciding to make one of their first EVs out of it. The H2 Hummer earned a reputation for being a vehicle for people that are proud to waste money. It only had a few good years of sales at a time when gas was super cheap and the brand died quickly when gas prices went to $4 per gallon in ~2007. After that, it was seen by many as a sign of stupidity on the part of anyone that still owned one. This is probably why you barely ever see them today. This, and large super duty trucks used for long distance towing, are the worst case scenario for EVs. I think GM is going to sell very few of these. Really bad product choice that was probably made by some geezer MBA, bean counter, or marketing schmuck that was given a leadership position and has nostalgia for something many others would associate with failure. Don't bother with an assembly line GM. Just hand build them in a warehouse somewhere. A few per week is plenty to keep up with long term demand.
