I've never seen 300kw on a charger, but my Taycan got up to 270kw. It charged from 20% - 70% in 12 minutes at that rate. Hummer is just crazy inefficient and huge AF battery compared to every other EV out there, but it's a Hummer, so what do you expect? All good!
😁
@@Bfranklyn731 Did you really just contradict yourself like an idiot and managed to be upvoted by a circus of clowns? Yes. We’re fully aware that the largest fully electric pickup truck on the market also has a large battery. It’s common sense. Does parading around KZhead calling the Hummer “inefficient” make y’all feel better about your own EVs?
@@mybro727 not sure what your getting at, I just like the hummer ev. Wish I could get one
@@ferkdizzle ummm no😆
Still doesn’t justify the weight of this car
That's pretty scary power. At my work something consuming that kind of power is hard wired. Hard to believe it can be done so safely by clueless people. Tremendous engineering here.
I’m excited that TFL finally has a Hummer EV to test!!! Give it to Andre and let him go wild!!
TAKES 4 DAYS TO CHARGE IT! I HOPE YOU HAVE PLENTY OF TIME TO VIRTUE SIGNAL YOUR NIEGHBORS EVERY WEEKEND
0 to 60 in 3.3 seconds a 9000 lb vehicle is reckless and stupid, and the kind of person so impressed by that is likely to be the first to skewer a bus full of kids with one. I'm all in favor of performance and such but this is far beyond anything that belongs on a public street.
I heard the Lucid can hit 300 kW, however briefly. The Hummer needs this charging speed with its sky high consumption. All EV trucks should support 250 kW so you can get decent recharge rate when traveling at highway speeds or towing.
Agree. 250kw minimal sustained or its not practical for towing. Towing can consume 1kwh per KM or per mile. So 200kwh battery to 80% is 160km of range for 40 minutes of charging.
@@matter45 Megawatt Charging System (MCS) all the way. Up to 3.75 MW with the current standard!
Most modern EV's can hit 300kW charging, but that's on paper. Porsche can hit 350 but it charges on average 150-250kw. Real world is different than paper specs...
@@AndrewPL5 Only the 800V vehicles exceed 230 kW for more than a few minutes. Porsches can hit 270 kW. EGMP can do 240.
@@jghall00 like I said, they can on paper. Watching real world reviews on the vehicles prove otherwise. Mainly a charger issue and most non Tesla EV chargers suck. Again, proven by most reviews.
General public has no appreciation for the insane amount of power running through those cables. Hard to believe Joe Public can be trusted to handle this stuff.
Seriously. Mind blowing.
yup , they consume 1.67 month of my whole house electricity consumption in 50 minutes !!! crazy amount !!!
"That is...mind blown, Tommy!" *immediately shuts the door on him* lmao, you guys are too much
OK guys, you've convinced me - I don't want an EV...
$60 for 212 miles of range? Jeez… that’s kinda expensive.
So... .33-.43 @ 141kwh is $45-$60! For 212 miles, that's 19-28 cents per mile, but at $4-$5 per gallon, that's only... 17 to 20mpg, which is no better than most modern half ton pickups. Yay. And an hour to charge to drive 3 hours.
That's assuming you use public charging everyday. Daily DC charging ruins the battery capacity and quality long term. A lot of power companies offer reduced electricity costs at night ranging for residential use ranging from $0.02kwh to $0.07kwh. Regardless, the HUMMER EV is still extremely inefficient.
@@ap31996 of course. It's just so bad...
9:34 This wasn't a "moonshot" in the sense you're thinking. The interior of the GMC HUMMER EV is a celebration of the fact that GM helped build the Lunar Rover (an EV, obviously) for NASA.
Great job guys! Thanks for making this video.
lucid air has 800v.. reason it drives on 400v is because all the supplier subsystems are based on 400v not 800v.
Lucid is 900V. Everything designed in house.
@@bahamatodd lucid claims it does nominal 900v but it really does 300kw in practice which puts it at less than 900v. The software is not designed in-house they use QNX, the DC/DC etc all provide 400v to HVAC etc none of that runs on 900v (which is really
@@bahamatodd The Lucid Air battery uses 6,600 21700 cells. 220 series x 30 parallel = 6,600 cells. Using 220 series, 3.636 V nominal cell voltage, the pack nominal voltage is 800 V. Using 220 series, 4.2 V peak cell voltage, the pack peak voltage is 924 V. Usable Energy = nominal voltage times the capacity = 800 x 150 = 120 kWh (slightly higher than 118 kWh - but this is only an approximation of net energy).
I saw my first Lucid yesterday and I think that one can charge fast too, great video, free charging ain't bad
Sounds like future GM vehicles may get two charge ports so you can combined two lower output stations to get rapid charging.
I was just thinking this the other day
It'll be interesting to see how the guy behind you in line reacts when you take two charging spots.
Didn't tesla offer this as an option years ago
@@jrod6236 I don’t think so. They have two ports on some vehicles, in some markets, but it’s because they use their own proprietary plug, like Apple does with their ridiculous charging cable, and then also a port for a region standard plug. But the car does not allow dual input for faster charging.
@@motors1103 similar to how we fill up a 48gal F250 then another 80gal gas in the boat we’re towing lol. Ever have to swipe you’re credit card at the pump 4 times?
Good job guys, looking forward to more Hummer content!
Sorry guys. It dropped because I turned my AC on at home 😂
GM estimate for charge times are 246 hours at 8 amps, 164 hours at 12 amps, 30 hours at 32 amps and 20 hours at 48 amps. That would be 0% to 100%, got these numbers from an online GM training course for the Hummer EV.
The amount of power flying into that thing is impressive! Calculated in miles per hour of charging only comes in at 438, which is still great! I’ve seen my Tesla charge at just under 600 miles per hour though
So most people in the USA either can't afford this vehicle, or can't get one because it's not available even if they could afford it. Waiting realistically to charge this on a trip could possibly take several hours if you didn't have access to one of these high power charging stations in your area. It's a cool vehicle in the way a yacht is a cool boat.
EV's are a neat idea - but by the time you finish charging the vehicle - my gas powered Hummer and I will be heading down the highway ahead of you about an hour.
11:41 It appears that the HUMMER EV's charging profile might not be completely finalized, but also, the Hyundai and KIA E-GMP cars will do the same thing occasionally. It seems that they are just doing a system check mid-charge to make sure everything is okay with the battery and charger. In fact, it's possible that that might have even been on EVgo's end.
At first I was considering one of these, but this just sounds totally impractical. You have to locate one of these stations that's convenient for you, then you have to kill probably close to 2 hours had they been near empty and filled up completely, then you're still paying probably 100 bucks. On top of that, once they get the population on EVs, they'll crank up the charging cost to equal what you would have paid in gas anyway. This would probably take several days to charge at home. I think im going to pass
plus no bed. that spare takes up a lot of room back there. Not practical at all. I guess a Hummer isn't intended to haul stuff
It would take exactly 24 hours to charge on the home charger I have for my two plug ins. 19 hours if I upgraded it to 50 amps. But that's from 0-100%. And you'll almost never be in that situation. The worst case scenario would be if you're coming back from a road trip and you return with nothing left. But even then you only need enough to get you though the next day, which for most people is going to be less than 100 miles.
This garbage can is Miles Out Of Reach for middle class Americans one of the many punch lines is that if America experiences and EMP I sent here by a hostel Nation just one could shut down the entire grid and these electric sleds would serve very well as boat anchors
Hilarious how they talk about how much “faster” this is than a Tesla. A Tesla would go from 20 to 80 percent on a 330 mile battery in 15 minutes. It’s all about miles per minute. Also a similar range charge at a Tesla Supercharger would be like $15. So funny how they act like this is such a good thing for the Hummer
Saw one of these here in Ft Worth over the weekend and I have to say it did look cool as hell!
Saw one of these on a so cal fwy not to long ago. Forgot how big a presence hummers had on the road!
16:08 That's actually in keeping with how GM has done EVs. The Bolt EV works the same way. 0% to 50% is the fastest, 50% to 70% is passable, and after 70%, you're better off moving to the next charger unless your at the location for more than just charging (e.g., eating a Popeyes).
all EVs work the same way
@@tychang8669 No they don't. Some EVs have extremely high peak charging at the beginning with a steep ramp down starting around 20% to 30%. Others maintain a much flatter charging profile. The Audi e-tron charges at ~150 kW flat from 0% to ~85%. And that's just nickel batteries. LFP can charge at peak rates nearly all the way to full.
@@newscoulomb3705 he knows his stuff and GM has the research
Can't wait for the upcoming videos and reviews on this
Another great video, I can watch you guys all day long
Great video guys
The 800V/400V charge/drive switch is good engineering, not cost savings (don't know what would even mean here). It's an Ultium feature.
I'm assuming when you put it in WTF mode it also switches back to the 800V mode as well.
@@sipher3516 this is TFL. Half the staff is anti-GM.
If an 800V battery is more efficient, an 800V driveline is also more efficient. The engineers would have to answer the reason for the switch.
I charged my Tesla model 3 at a super charger the other day and it added 80 miles of range in 12 minutes at over 500 mph. Didn't see the kws added but seems about the same.
Awesome video guys
Was there any charging animation on the headlamps?
Did 60% of a charge in about an hour... while the Hummer is nice, EV still has a very long way to go before it competes with gas in anything other than instant acceleration. I'm definitely looking forward to what the future brings and these are big steps being made. Good video!
That’s honestly terrible compared to current EVs.
This video was brought to you by the nearest coal fired power plant.
Roman & Tommy, Next time I wonder what would happen if you grabbed the charger next to it and plugged it in once the original charger slowed down. This would show if it’s the charger itself that’s heating up and slowing things down or the battery on the vehicle slowing things down. This might be a way to get charged faster by switching chargers every 15-20 mins. While this is better still waiting an hour to get 212 miles miles of range doesn’t compare to a 5 min fill up which adds 500 miles of range on an IC truck.
My thoughts exactly. A non-issue, though, if you charge at home nightly for daily driving rather than depending on a charging station.
Any auxiliary AC power outlet? What maximum power output?
You guys had me crunching numbers on this one. I don’t know what gas is price for you’re at, but around here right now this hummer would be getting around 10 1/2 miles to the gallon, on a strictly economic basis. Check my math tell me if I’m missing something: 212 miles of range at an estimated $60. Gas around here is +/- 3 dollars per gallon. That same $60 would purchase 20 gallons of gas. Dividing 212 miles by 20 gallons gives an equivalent of 10.6 miles per gallon. Seems like a hummer to me.
EA has charges that charge by the minute. Charge for 15 minutes and move on, laughing at how cheap the charge was.
Most places are closer to $4 a gallon then $3!
@@gmv0553 $2.80/gallon here in GA. I could fill my car from empty and get 600 miles of range in literally five minutes and it would cost about $45. EVs are for suckers.
So when do you guys get the one that you ordered?
until they can get the " fill up" down to 10 mins / 15 max...ev's are a hard no for me...i know most pp charge at home overnight, but i do a lot of road trips
We're already there with the sedans. Model 3 and y come to mind. Some people even complain that the car charges too fast and that they don't have time to go to the bathroom and grab a bite any more.
I’m pumped to see the videos on this beast!
I wonder if the limit to start reduction is the vehicle temp or the charger temp. I wonder what would happen if you move to a different charger if that would allow for another highspeed charge or not.
@Larry Butler if it's the battery temp, then you have a point. If it's the charge station, then you are crazy.
9000 pounds, it’s 4000kgs. Here, in France you can’t even drive it with a car license. You need a truck license.
Added range (miles) per minute is what's matters.
3:46 You can press the Session Details button at the lower left of the screen to see a breakdown in current, voltage, power, etc. It's much more informative than the base screen.
@2:21 can someone clarify for me please; charger says output to 920 Vdc but cable has 600Vdc written on it !?
Can’t wait to see the hummer doing some off-road testing
Maybe the EVgo is not used to charging at that high of kw for long periods of time and was overheating, so it slow down it protect itself
How strong is that roof incase of a rollover
Wait til you charge it at home LMAO
If the slowdown in charge rate is due to heat, then this is kind of like laptop computers which have an amazingly fast CPU/GPU but then throttle back the speed right away because their thermal design cannot dissipate the heat fast enough. It would be better to have a somewhat slower max charge rate which could be extended for a much longer period of time.
Was thinking the same, a good peak is useless, it ended up taking a long time anyway.
How long would it take to charge at home on a level 2 charger from 20%-80%?
forever
Does riding with the roof down drop the range? Thanks for all the cool reviews!!
Can ev's run ac or heater while charging when weather is extreme?
The area I'm in at this moment has two DC charging locations near me. First location has three stations. A 150kW unit, but it has only been putting out 36kw, a 150kW unit, that fails to initiate, and a 50kW unit. The other location has two 50kW units. I spent a total of 1 hour charging yesterday (two 30 minute sessions at 50kW). Charging this Hummer would be painful if you only had access to 50kW chargers.
With small electric RC vehicles the charging rule of thumb is to charge at a rate that matches the MilliAmpHour MAH capacity of the battery. So a larger battery can charge faster basically. For example, a 700 MAH battery should charge at .7 amp and a 7000MAH battery should charge at 7amps. With the Hummer EV having the biggest battery on the market I’m not surprised it also charges the fastest with that in mind.
Yep, that’s the C rating, or capacity per hour. Even at 300kw they’re only charging at 1.4 C. Model 3 maxes out around 2.5 C when it’s under 15%
You also have to consider paying k voltage and cooling. When I did RC, my version of cooling was a fan. These vehicles are more sophisticated. And higher voltage means faster charging without increasing current, which builds heat.
A wise man once said, “ain’t nobody got time for that”.
So it looks like higher peak charging is not needed, but the ability to hold that higher state of charge longer. I've seen that in my Leaf. After 50%, it can drop rate.
Might be a dumb question, that’s the only charging port in the back of the vehicle? Just thinking for towing purposes.
this bad boy consume of 1.67 month of my whole house electricity consumption(84kwh) in 50 minutes !!! crazy amount !!!
How about C-tops? Like cruciform (cross shape).
I just saw a Barrett Jackson where a Hummer ev sold for over 300k it might have even been 400 I forgot. It was so many times msrp my mind can't even remember what that sucker paid. I get the 110k but why you'd pay much over that is beyond me
Tax writeoffs
Lets see this roof off in Moab! I have to get my red rock fix vicariously through you guys since I'm so far away!
If it slows due to heat I wonder what would happen if you changed charges halfway through charging. Is it thd charger heat or battery pack heat?
The battery pack will always be your weak link. You can only charge a cell so fast before the negatives outweigh the benefits.
"I don't like square burgers lol" I drive a Bolt so seeing a charging session like this (on evgo no less) is mind-blowing. I can't wait till this trickles down to cheaper cars.
happy you guys finally got a hummer ev ... I CANT WAIT TILL I GET MINE ...
In 4 minutes my Honda CR-V tank would have been filled already at 500 miles of range
Looks like charging to 50 or 60% may be the key to getting back on the road faster (assuming one can make it to the next charging station).
Then back on a charger in an hour 😂
Those Rode mics are absolutely absurd to me 😂👌🏻 Great review as always though 😂👌🏻
At least the display didn’t read “one car at a time please”😂
I'm excited for these next videos about the new hummer
Have this truck... takes me a couple hours to get to 80% on the supercharger evgo. At home... LOL a week to fully charge!!!! 1 Mile per hour. Really hoping other chargers are...faster... and its not my truck!! Love your very informative videos!!! :))
I wonder if at some point it would be better to have 2 chargers plugged in to a vehicle. If you had the batteries as 2 separate units like old school dual fuel tanks. I feel like that would significantly reduce the charging time
This is called parallel charging and it looks like some manufactures are considering this but your limitation is still the plug your changing and the station you pull energy from . And on top of this bms systems in the distraction of energy per cell already divide the energy . Limitation is really how fast you can safety charge each individual cell. If the cell can be charged in 10 mins then in theory the entire pack could be theoretically charged in 10 minutes regardless of size but it’s once again the distraction , heat management, Volts , Amps and charging losses . A pack of 200kwh size to charge in 10 mins should probably take some kind of insane cooling system of cables , the pack , the charger and extreme voltages of 4000 volts at 2000 amps
GM has applied a patent for this
How long would it take at a 50 kw charger ?
These guys have a funny definition of 10 minutes.
Can’t wait to see you guys take this monster on your TFL off-road course 👍👍👍 maybe see if the crab walk feature is actually useful or just a gimmick

What is the cost per mile on that recharge?
Once it dropped at 52% I would have moved stall. Might be the cable/stall that is overheating/throttling. Moving the stall would have told you if that was the case.
Can't wait until you put it up against the Ford lighting and the Rivan
300kW at 400amps! I wonder if the Hummer EV is limiting it at 400amps or if that’s the charge station. At 500amps it would be over 350kW. Great info thanks for the video!
3:15 I believe plug and charge should be active on the HUMMER EV; it's been working flawlessly on my Chevy Bolt EV for several months. Either way, I'm not sure that paying with a credit card is a valid price. It should be considered the worst-case-scenario pricing.
I can't think of anything more fun to spend 70 bucks to sit at a "fast charger" for an hour a couple times a week. Lol.
Most likely the battery overheated, & rapidgated suddenly. BMS told charger to slow down, battery cooling caught up and brought the speed back up
Charger cable probably overheated.
A neighbor has one. Looks pretty amazing, except from the side view. Great charge rate! Not the best, but a close second. 👌
Great video! I suspect the charging was at times limited by the station and then limited by the truck. Looking forward to your other video's. Including a towing test.
So how much $$ to charge it to full
What are the pros and cons of 400v and 800v also what exactly are the components that make an EV 800 volts? Thanks in advance!
Advantage of 800 V: less current in the charging cable and connector, maybe less current in the cable to the inverter and motor (if it also drives at 800 V). Disadvantage: Higher voltage components required (inverter), some components re not readily available for 800 V (heater stacks, servo pumps, DC/DC for 12 v, etc.). And some DC fast charging stations cannot deliver more than 500 V, so and additional inverter is required to use them. Wrap-Up: 800 V makes sense for massive electron guzzlers (like the Hummer), but probably are overkill right now for for efficient cars like Model 3 or Model Y.
@@bernhardleopold6702 As an example: If I want to turn a Model Y to 800 volts the only component I'd need to replace/install is an 800 volt inverter, anything else?
Over $60 to charge up your EV? That’s about the same when I would pay to put gas in my truck so there is no savings Therefore I could be in and out in less than two minutes filling my truck up with gas
If you guys had the truck on, it will slow it down when the AC in the cabin tries to cycle at the same time as the battery cooling.
It looks like it comes off its peak charging rate around 38%... That's disappointing, but it should have definitely held 150 until at least 80% there's no excuse for that.
wish i could afford an EV with 800V architecture, but im poor. I'm forced to stick with my old silverado
These guys get excited about wasting 1 hour to drive 250 miles, imagine how excited they would be filling up an F150 with a 36 gallon fuel tank in 10 minutes and being able to drive 600 miles.
let’s do it again but get an actual dollar total
750 miles! I’ve got 12,840 on mine already! We went from Maine to Florida to visit my family, then from Maine to California a week after we got back! I’ve never had so much fun on road trips!
In the Hummer vs Rivian test, did GM's programming defeat the Hummer by maxing out its top speed at 106mph?
I just seen a trailer with 3 Hummer EV's on a trailer on I-75 south!
Ok on the fluctuation of the amperage delivered, this is a mix of investigation and speculation so grab your salt shaker, but I would imagine Tommy is right about the temperature being the regulator. It appears that information such as the battery, cable, and internal components of the charging station temperatures, CAN be monitored and, presumably, the charging rate varied to cool things down if it overcomes a certain threshold. AND he's right about Popeye's being the choice as well ;-)
is that laowhy86?
Good video however I'm not sure why all the excitement for a 1 hour (60) minute charge? Most of the chargers are not the level 3 and with the limited range (range anxiety) and the hight cost of the vehicle - still like my gas powered cars/trucks. With the savings in cost that buys a lot of gas anywhere from 5-7 years worth. Love your guys channel.
