How Did It Go SO WRONG? Here's What Happened When We Tried a Hummer vs Rivian Charging Drag Race! 

check out the actual drag race HERE: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_gH2jxOqc74.html

I agree with Tommy. It's all about how many miles you can get during a session. This is how you plan your stops on a road trip.

Thank you for being the voice of reason, Tommy! Efficiency absolutely does matter when comparing charging rates. It's amazing how many people don't realize that. It's partially OEMs fault because they keep listing % over time rather than miles over time.

+1 to Tommy for knowing the difference between power and energy. 🙂 (And for defending the range gained per minute metric, even though you still got smoked.)

I would love to see all 3 EV trucks do a road trip race where they leave at the same time and have a destination several fast charging stations away and see who wins. ( like out of spec did with the electric SUVs)

It’s actually a more accurate drag race because you used the same charging points. You guys are still proving the non-Tesla network sucks

I really like the “miles added in 20 minutes” metric and comparison. Sure there’s a bit of wiggle room on driven efficiency, but I think it’s close enough to give an idea for realistic road trip charging. I’d like to see a Hummer vs. Ioniq 5 for range added. A battle of the 800v vehicles.

Miles in 20 minutes most valuable, in my opinion.

The charging speed is indeed relative to the battery size, 1C 2C 3C and so on. If you have twice as many buckets, you’ll need twice the flow to fill each bucket at the same rate

Forget range anxiety, charging anxiety is really the bigger issue. Last hunting trip I drove 200miles to deer camp, and saw one charging station about 100 miles out. If that one hadn't worked my whole weekend would have been ruined. For a daily commuter an EV may be fine, but as an only vehicle they are way too limiting, and that will continue to be the case until the network is significantly improved, in availability, and reliability.

I believe the 20 minute scenario is better for most people however that will vary greatly depending on the SOC of each EV. Maybe you should start at 10% for every EV and do 20 minutes and if it takes longer than 20 minutes to reach 80%, note it as additional time needed and run the test out until it does reach 80%. For vehicles such as the Ioniq 5 and smaller battery vehicles it would be nice to know if you can meet Hyundai's claim of 18 minutes for the 10-80%.

I also agree with tommy. If I am spending 20 minutes at the charging station, regardless of what the battery size is or what the charging speed is, I want to know how far I can go from that charge

A race based on range added calculated by using the EPA estimated range. For example, on Hummer EV, 329 divided by 212 times kWh added.

Absolutely brilliant - telling it like it is! I think there is real value in the miles per 20 minute metric, for road trip charging it is probably the most relevant stat, maybe followed by price, but as a distant second. To compare, a Model 3 coming in hot and empty might be able to get 200 miles in 20 minutes - I'm with both of you on the results that matter, 20 minute distance, and 10% to 80% time too - they are both relevant for EV road trips, in some respects this is a shortened version of Bjorns 1000km challenge, as it s a pretty good indicator of performance in that test too. Awesome to see a convert say Hi as a direct result of your videos - that must have been really rewarding. Keep up the good work - especially the charger shaming - it needs to get better, but please bench mark a Tesla too, in my experience, it just works 100% of the time.

Every EV driver on a road trip quickly realizes that real world miles per minute is the important metric. To improve this speed: Try to arrive at the charger with 15% or less remaining charge. Make sure the car knows about your plan so it can prepare the battery for 15-20 minutes. Don’t charge much higher than needed.

Tommy is of course right - Miles is the metric that matters. The Hummer has to have a higher charging speed because it is such a bad design for an EV given current capabilities - massive battery to compensate for massive weight. If you were at 90% of all fast chargers in the US, which dont have 350, the Hummer would be demonstrably worse in every way.

The Hummer is exactly what the old Hummer’s were, obnoxious and inefficient. The Hummer’s faster charging speed is an absolute requirement, as it needs fast charging to make up for the inefficiency and larger battery pack.

Dont take the number from the dash but take the Real World consumption (the ones from your efficency tests) and compare to the kw gained. I dont trust these estimated numbers. You can even compare it to the Trailer consumption that way ... id like three numbers that way: range gained for City, Highway and Trailer if you have those numbers it would be awesome.

The charging speed IS related to the battery pack size...each cell has a max speed at which it can charge. The more cells you have the faster you can charge (assuming the same cells in each car). There are lots of factors, but the larger pack should be able to be charged faster

Again, big points on how we need to improve the charging network before everyone trades in their gas guzzlers. I’d love to see the Hummer and Rivian go off road together. Probably would be better to do a R1T and compare towing and functionality, although I love the R1S as a family hauler. The Hummer is not a family hauler by any means, but I think it might beat the Rivian off road, and lose functionality. Price is insane on both.

Miles added per unit time. I want to know how far I can go until I need to stop again. After seeing these videos along with the Munro teardown inspection, the Rivian doesn't strike me as a well designed, quality product.

I think what Tommy was saying is totally valid. The amount of kilowatt hours you add is irrelevant if it doesn't get you to your next destination due to vehicle efficiency. I'd be interested in a drag race to add 200 miles of range or something like that. Of course that is affected by your recent driving history...but maybe you can calculate a baseline using the manufacturer's specified range and available battery capacity to get a range per kilowatt hour.

Do you get a notification on your phone when charging stops or fails? I'm just wondering if you can go eat while you charge, or if you have to be watching.

The EVgo stations in Fort Myers are the only ones that actually work for CCS charging. The EA stations at Walmart are a real hit or miss situation. Sometimes they work and most of the time they don’t, really at the moment the sheer lack of consistent CCS stations keeps me with the Tesla product. Would be nice if the CCS system was as reliable as the Tesla network, but alas it will never be because the various automakers using CCS do not have any skin in the Charging game. They need to all build out CCS systems that will be as reliable as the Tesla system, or at the very least all convert to Tesla charging and help Tesla build out the network. Ridiculous how bad the CCS systems are.

Miles in 20 minutes is the most valuable info to a consumer. To get that data though, you should do a 70mph efficiency test then take the miles per KW/H times the KW/H of electricity dispensed in 20 minutes.

The real race, as Tommy pointed out, is how many miles are added. More specifically I look at how long it takes to charge to regain 150 miles. That’s about as far as I want to drive between rest breaks anyway. So say starting from a less anxious arrival charge of 20%, how long does it take to add 150 real miles?

Hummer gained 45% Rivian gained 44% That means they both charged at an effectively identical 1.3C charging rate. Compare that to a Model X, which will do 57% at a 1.7C charge rate over 20 minutes. Tesla is clearly getting a lot more thermal performance out of their battery packs.

Are you sure this isn't an issue with the Rivian R1S? This is still an early production model, right? I've been seeing a number of Rivian charging issues being reported related to Signet chargers (on both Electrify America and EVgo).

Battery size DOES affect charging speed. As battery gets full, it's able to accept less energy/time. Adding 10kw to a battery that's almost full will take more time than adding the same amount when the same battery is almost empty. Basically that's why the Hummer accept almost the amount of energy that goes in a Tesla in about 20 minutes vs a Tesla being charged to 100%.

Miles added in 20 minutes is a good metric but it should probably be hand calculated "kWh added" times "vehicle long term efficiency average" rather than relying on the vehicles GOM. 20 minutes is about how long I expect to be at a stop when travelling in my Ioniq5 and I think it is a reasonable amount of time for a stop.

Actually Tommy’s right, but you should calculate range added based on epa mpkWh (or your real world average mpkWh) and kWh added instead of what the vehicle happens to say for estimated range at that moment.

You charge both vehicles for X amount of time and then drive them on the same route/speed and see who gets back down to their pre-charge percentage first.

If i were hummer engineer id put to plugports so i could suck twice 350 kw Form two stalls each charging half the battery. If its half the time blocking two its the same than blocking one for double that time right?

The test is doomed to failure when trying to test the speed at stations that are not reliable. A better test would have been to plug in at the office at level 2. Or even level 1. In 20 minutes which would have more range added in. Since that is where most EV's are supposedly being charged up. The temps being equal sitting in the garage.

7:41 Hummer 96.9 kWh $10.03 at 12:56 Rivian 59.9 kWh $10.03 same price Hummer 37 kWh bonus.

In a real world scenario of an extended road trip (trying for max miles/time over the trip duration), you are pulling in with your just your safety margin left.. Depending on comfort level, let’s say that’s 10 miles of range, and then charging untill you add enough miles to get to the next charging stop. If that’s 150 miles (to stay high in the charging curve), then the test should be how quickly you can go from guesstimated 10 to 160 miles of range.

The size of the battery does determine how fast you can charge the battery without damaging it. That’s called the c rating. The bigger the battery the faster you can charge it safely

Who gets the most range in 20 minutes.... After all its about spending less time at the charger to get where you want to go. So what if the Hummer charges faster if it needs such a larger battery to get there but its not charging fast emough and I'm sitting at chargers all day.

Miles in 20 minutes most important , especially if you have babies or kids and your trying to get home as fast as possible if they are upset .

I think the 20 min is relevant as well as 10-80%. Maybe do both at the same time? Also I agree with tommy, I don’t care how many kWh are added I just care about how many miles I can drive for a given period of time I spent charging. :)

Dragrace Charging!? …I Love love this idea for future benchmark testing and an important performance mark for me when and IF I’m in the market for one of these expensive EVs. Awesome job Gentlemen.🙂👍

To me the more important number is how many miles of range I can get in 20 minutes. Adding KWh is great but it means nothing in relation to me getting to the next destination.

EVs' Archilles heel(s) are: (1) poor range, and (2) long refuel/recharge time... I am skeptical that EVs will ever approach current norms of about 500 miles range and 10 minute refueling... Think about it… Can you really replace all the energy needed to move a vehicle 500 miles in 10 minutes? Power losses (heat) in the charger and connection systems increase with the square of the current… Physics will dictate limits (at least until/if we discover high-temperature superconductors)… After the early-adopter phase, EVs will have to meet or beat those 500 mile and 10 minute range/refuel time numbers to achieve wide acceptance... Just sayin' 😎

10 to 80 would be cool. Both have good points but Tommy's mules added is how I think of gasification g up my car because I know a full tank gets me 408 miles. Keep these coming.

As always the real looser in this race is EVgo, as well as all other non tesla chargers. Do you really need a rocket scientist to make a system that can reliably dispense electricity, this is so sad

Could you do a charging curve next time please?

Miles I can drive with a 20 min charge is more important than how many kWh added. Small batterys will charge at a slower rate typically but also more likely fitted to smaller more efficient cars meaning it will equal out over a wide spectrum of cars on test and is more useful to real world usage. Some cars don't even tell you how big the battery is as they know it doesn't really matter, only how far you can drive matters.

This video was fun, I love the friendly banter!

so interesting to see them both discussing/arguing about the charging states of their vehicles. keep the awesome content coming!

Miles is more important that energy!

This was VERY good!! It showed the current state of the infrastructure. YES, it is at the very beginning stages and has some development to go, NO DOUBT! One VERY interesting point is how that charger, charged you $$$, it was by time spent and not electricity absorbed!!! WOW!! That is similar to using the large nozel at the diesel pump vs the standard nozzle and paying the same final price on the two mintues of pumping!!!

ICE vs. Electric. *Electric - per this test = 40 miles per dollar* *ICE = 7 miles per dollar* How? 4 miles per KWH (not in a hummer of course - but say in a telsa or polestar or lucid) 10 dollars for 100 KWH 10 dollars for 400 miles 40 miles per dollar Compared to gas car at 4 dollars a gallon. 28 miles per gallon (ave small sedan) 28 / 4 = 7 miles per dollar. Lets say a Rivian = 2 miles per KWH And an ICE truck = 16 miles per Gallon Now.... *Electric Truck = 20 miles per dollar* *ICE truck = = 4 miles per dollar* 8:10 -> 150 miles 96 KWH 10 bucks = about 15 miles per dollar for the Hummer (150 /10).

Ultimately, Tommy's metric makes sense - how far can you go with 20 minutes of charging. The challenge is in making sure all of the variables involved are equal. Getting a solid miles per kWh figure is the first step - relying on the guess-o-meter is about like relying on the car's own MPG calculations - sketchy at best. Looking at EPA combined figures, that puts the Hummer at 1.39 miles/kWh and the Rivian at 2.08 miles/kWh. Now that there's a efficiency number to work with, it's down to showing up at the same state-of-charge and making sure the charger is in working order (which as the Micas show us, is a real challenge). But they got a charging number - in 20 minutes the Hummer slurps down 96.8 kWh to the Rivian's 59.9 kWh. Using EPA combined mileage numbers, the Hummer picked up 135 miles of range to the Rivian's 125 miles. Obviously, the Achilles' heel of the Hummer is its prodigious consumption, and it will knee you in the groin if you are stuck on a slow charger. In one hour at a 50kW charger, the Hummer only picks up 70 miles of range to the Rivian's 104 miles. If it's a cold or hot day, those numbers will dip even farther. The worst-case Ioniq 5 gets 2.94 miles/kWh. On their 77.4 kWh battery, going 10-80% in 20 minutes means they have to onboard 54.2 kWh in that timeframe, which should be easily possible on the same (working) charging station the Hummer and Rivian used. That brings you 159 miles of range in 20 minutes. Or, in my 50kW charger example, an hour gets you 147 miles. Either way, there's a reason Roman and Nathan used the Ioniq 5 on their electric Cannonball trip.

Love these videos, they really show how much this technology is in its infancy. Loved the look on Tommy's face when he realized he "lost".

Still look for mile per kilowatt at 60, 65, and 70 mph. I would be curious to see how each truck does. When driving my Chevy Bolt around I find that at 60 mph I get the best efficiency and going up to 65 drops it by 1/4 to 1/3 and going 70 can drop it a little over 1/3 of the efficiency. Just to give some real world examples my bolt can do between 3 to 3.8 m/kw at 60, 2.7 to 3 m/kw at 65, and 2.4 to 2.6 m/kw at 70. What people have to take into account is that these numbers are multiplicative and just that little but of change can have a massive effect on actual range because the battires are a fixed size. So a 66 kwh battery can have a range of 250, 198, and 175 respectively

So I'm sure there's another factor you haven't taken into account: -- Throttling algorithms The charging station is charging by the minute (or by time at least) not by Kw dispensed. The Hummer was hoovering up nearly 300 Kw/hr for about 20 min. At some point their algorithms will kick in and throttle the charging rate (i.e. charging speed limited by charging station). So in a perfect world, more akin to a company charging per Kw, and not per session time, the Rivian would probably get the same amount of miles per time (10 min, 15, min, 20 min, etc.) as the Hummer.

Now do an efficient EV...

What might be a better test is to "charge to 100%, drive , time how long it takes to add charge sufficient to add 200 miles of range." That's more indicative of road-tripping. Especially caravan road tripping where multiple vehicles are likely to stop at the same time. And would take into account both efficiency and charging speed. A more efficient EV would do better, an EV with better charge curve would do better.

EV charging sucks. When I go to ANY gas station, the pump works about 99.9% of the time. With charging, one charger didn't even work. What a pile of elephant 🐘 💩💩💩💩. Then, one vehicle cost more for the same amount of power dispensed. That is crooked AF.

It's all about miles added per minute PERIOD! Who cares how much power you draw, max or otherwise. How much time do I have to spend charging to get to the next one. That is the only metric that matters. Tesla owner here, with Rivian coming soon. So excited to get the Rivian, but as a road tripper watching all these public charging nightmares has me second guessing this decision. Tesla Supercharger are just everywhere. EA has what 4 stations when you get there. Maybe they all work or not. But when I pull up to a supercharger with like 20 stalls, none broken, plug in, it just starts charging in about 10 seconds. I can go for breakfast, lunch, or whatever, and it will keep charging, nor errors, or whatever, which is so unacceptable. So..........on the fence about trading in my tesla for my much anticipated Rivian. I'm Q2, so I have time. It''s not looking good at this point. Rivian is strapped for cash. They are losing on very vehicle, and have said they have cut back on expenditures. What does that mean: less Rivian chargers???? if so, will keep my Tesla

So here's what you should do: - I don't care what editorial direction you want to declare a "winner" as long as you give all the data. Personally since I'm buying a vehicle and not a charging system, I care about mileage more than KWh, so to answer your argument Tommy is right. - feel free to give us KWh added, I still am curious whose tech did better - give us charging speed over time so we can optimize our curves - give us mileage added. Do this by charging for a period of time, and then multiplying the energy added by the efficiency from the EPA (removing any bias from driving style as this is standardized) IMO the "winner" should be the most miles in the latter, over a 30 time. The time is up to you and the viewers at large. Personally I'd prefer to stop for 5-10 mins just for gas, or 30-45 for a sit down meal. So 20 is a bit of a dead zone. But I'm fine with whatever, really. I do think time is good for this "drag race" though. Charging curves are the most important thing, though. Start at 0, charge to max, and plot the charge over time. Then extract all the metrics from there. In fact, you could extract infinite "drag races" from that data, see how much each added from 10% within a period of time, and calculate the miles added. You can do this for any length of time and starting state of charge.

EVgo might finally rethink their per minute rate as more fast charging EVs will become more common. For example in my 2022 Bolt EUV for the same 20 min and $10.03 it will add at its beat about 15kWh definitely less than 20kWh.

For me the most interesting factor is that the Hummer sits on an Ultium pack, and so the Hummer charging speeds will be relevant to the Silverado / Sierra EVs (same pack) and will inform somewhat how the Blazer / Equinox can charge. And those vehicles will be Rivian efficient or better, because Tommy's right - it's about how far I can go after I plug in for 20 minutes and am not charger limited. Based on how capably the Hummer chargers, the rest of the Ultium vehicles are promising!

Electrify America is going to convince millions NOT to buy an EV.

Rivian's do not like being charged at over 150 kw. Anytime I've charged at 350 kw chargers with the Rivian taking in around 200 kw, it gets that Slower due to battery cooling warning and slows down to levels less than what the 150 kw chargers maintain at. If you're charging to 50%, possibly the 350 kw will get you more in less time, but if charging to 80%, they always seem to work out to about the same amount of time.

My experience with EVGo has been terrible. I got $250 free charging with my 2022 Nissan Leaf. I would not pay their prices. Easily the most expensive chargers I've found since they charge by minute and not by kwh like almost everyone else. Also their chargers are more often broken than not.

Misunderstanding energy and power, kWh vs. kW is unacceptable for an EV channel. That's what, 6th grade science? Sorry guys, unsubscribed.

Well no chit the charge failed in parallel! You were trying to pull 450kWs from the grid! Never mind the traffic lights behind you went out for a few seconds😂🤦‍♂️

Tommy is right. The metric that matters is how many miles were added in a given amount of time. The winner of a charging race is the vehicle that can gain the greater amount of miles in the fastest time. The "finish line" is a predetermined number of miles. The question is how many miles should be the goal or "finish line "? I think 130 miles should be the number. This would be half the miles needed for a week of average vehicle use based on current statistics (260/wk=13,520yr). A potential buyer of an EV wants to know how much time per week they can expect to spend charging at a fast charge location and how many times per week? This would be interesting to know especially for any potential buyers that do not have a capability to charge an EV at home. I think a time limit of 20 minutes per charging session is also good. I know for me 20 minutes would be the maximum amount of time I would be willing to sacrifice out of my day. Being mindful that an ICE vehicle can be fueled in 5 minutes and last at least 90% of the week. I think that 20 minutes twice a week is all that I would be willing to sacrifice for an EV. The results of such a charging test would be very interesting and useful to a prospective EV buyer. It would help answer the question of how viable of an option is an EV. Roman, your comment on the range being effected by driving style is not relevant. Yes, of course we know that range varies depending on driving conditions. But the purpose here is to simply get an estimated range based on average driving conditions.

Roman, Please get it right. It's the charging of CCS1 vehicles NOT all EV'S have that problem. The ones that use the NACS - Tesla connectors don't have that problem.

Battery packs are a big difference in size , range sucks on the hummer . For over 200kw battery size. Imagine a 200kw battery on a Small car 😮 over 600 mile range

The connection errors are the most frustrating thing to me. How difficult can it be to let someone plug something in and charge something up? If I could pull up in an EV, plug in, leave it, walk across the parking lot for lunch, bathroom etc, and KNOW for SURE my car would be charged 20 minutes later it would not. be so bad. However all theses connection issues with EVGO and Electrify America mean you have to babysit it the entire time. Its pathetic. As for which number matters most, they are both important but I do think the miles added is the most practical. If you are trying to get home and need a boost that tells you what you need. Of course you can't rely on any of the numbers, every charging station is different, battery percentage, battery temp all matter. It was disappointing to see the Rivian throttle because of battery temp they should be managing that with cooling.

The size of the battery doesn't matter ... The real question is how many miles you can get in the duration of charging. The Bigger battery in the Hummer would have been excellent, if only the car had 10,000watts worth of electric outlets like a Ford Lightening.

20 to 80 is best with time range and price becouse the hummer is like my armor 13 it charges slow it's huge and not rly good at using it's battery but It doesn't mather my phone will murder and iphone 14 pro max at max spec at max battery at anything so yeah the real answer to EVs is atlest 200 kwa and atlest 800 volt charging with atlets 600 amps so fast charge and big battery there is no way in hell you can make enough stations that will help me if my wife is giving birth and my battery is only 130 kw that shit is like working with a handicap even before I start also 90 000 ? I'm sorry but if we count in price we get duble the car for 20 grand more that's like buying a new Honda or a new Lambo difrence how is that in any way the hummers problem I swear your son is anty GMC aweys making fun of it for being to big or bulcky or not good enough are you crazy? For 110 grand you get the best ev period right now nothing comes close what will you get a 300 mile Tesla plad or a 300 mile monster truck I'm so surprised that in the literal county with the biggest manly men next to Russia and Japan and you people actually defend this little shit cars don't get me wrong I like rivien but that's like what do you want to buy a Suzuki swift or a jeep grand Cherokee with better fuel economy like u not only have a huge car but It can go longer then the rivien for what like 2000 pounds extra ? For me sorry but there is nothing that can touch the hummer right now and it's a staple for what you have to do if u want an actual useful ev couse the most people dont drive more then 60 mile a day shit is a joke ? Where do you live for that to be the case ? An island ? I personally do 100 and more some times every day so no a leaf up Id3 are jokes .. u want to charge me 40 grand for a bike with 4 doors I don't care who makes them but right now only 4 cars are usable vinfast vf9 radar rd6 Tesla model y and x and hummer ev rivian r1s is a maibe but not rly sure as far as I saw and I watched everything on RU-vid for it it seems a overprised shit same like the the lucid air cars ..

This reminds me of all the times I've pulled into a gas station, paid, started pumping, and then got a major error that wouldn't let me continue. Wait, no. That's never happened. A) Gas pumps are much more reliable. B) Gas stations are manned, so when a pump does malfunction, they can tape it off, so you don't waste your time. C) There are more payment options - including cash - so that you don't have to stand around hoping some crappy app functions properly. EV charge stations should be modeled after gas stations. Their current setup is garbage.

We simply do not have the grid structure to support multiple charging stations in many locations capable of pumping 100s of amps @ 800 volts and be reliable. You are talking $Trillions of dollars and completely new technologies...

What would I like to see? The Hummer EV for $50k. It doesn't really matter to me which > $100k EVSUV charges faster, since I will never own either one.

Test starting with 30 mile reserve, then charge for 20 minutes. Most miles added wins. Personally, anything over 2 hours driving (120 -150 mi) is as far as I go before needing a break.

I know you are related, but please stop arguing! This is supposed to be fun. Hummer wins! $10 for 150 miles is pretty cheap. Why the price difference though?

Do another "drag race" using 150kW stations. Those are still much more common than the 350kW ones. That's where more efficient vehicles such as the R1S shine.

Has anyone tried to make the Hev more efficient? By changing tires and body? Seems like it would be a great idea. If you could make it quickly/easily swappable, you could have an efficient commuter during the week and a hummer on the weekend.

Neither of these vehicles would work for anyone that I know. My friends and I cannot afford a vehicle that costs over $ 100,000. Yes, they may be cheaper to operate in terms of fuel/energy, but the cost of entry makes these vehicles something that only the fairly affluent can purchase.

Miles gained per minute of charging is most important! I wouldn't count on those unfair charging costs to make an EV purchase decision because evgo may get better at billing for amps used. If that happens the Hummer will cost about 20 to 30 percent more per mile of charging.

They charged $10 for the Rivian, and $10 for the Hummer ... And yet the Rivian got like half the charge.

My take away from this; if you are inpatient, waiting to find a charger that works? Get a Tesla. I would be taking a hammer to these POS chargers!👎🤮😡

The guy is correct -- the most helpful metric would be # of miles added after 20 minutes... or # of minutes it takes to add 120 or 150 miles of driving

Love your coal powered trucks😂. Lithium mining and coal powered = environmental disaster. Plus getting rid of lithium batteries is also a nightmare for the environment.

Tommy is 100% correct here. Miles added is the most important metric for fast charging. Who cares if you add 200 kWh in 20 minutes if that only takes you 100 miles down the road. You would much rather add 100 kWh in 20 minutes and drive 110 miles in a much more efficient vehicle.

his analogy about the two batteries was wrong. Adding more batteries DOES improve charge rates. Companies have been adding cells to phones to allow them to charge faster.

Tommy is right that range/miles added is what actually matters. The Hummer charges so fast because the battery is huge and lithium ion batteries charge much faster at lower states of charge. The Hummer has much more headroom to charge fast. The problem is then the Hummer only gets 1.6 miles per kwh on average. A good real world test is to do a roadtrip with multiple charging stops to see which truck is "faster." Also EV charging stations are still an unreliable mess and a lot of charging ability and speed is simply luck at this point.

OMG, with the slow refilling already being an issue against EVs, coming up to a charge station and having IT fail would frustrate me to no end. And this seems to be a common issue. EVs have a long way to go to be mainstream.

Efficiency! Help your old man Tommy. Saying mi/kwh is of no consequence is like saying mpg is not either. When I road trip miles per minute is the only real metric I care about.

I think the calculation should have been this: look at the kwh that were added, then look at the average kw/mi for each vehicle to determine the miles added back by the charging. Sure the HEV probably added more kwh to the battery in 20 minutes but it also burns more kw/mi.

Real world miles gained makes the most sense. The whole idea of faster charging is to spend less time doing it. So you can charge 200 Kwh battery in 5 minutes, but it won't matter if you have to do it every 5 minutes.

Both start at 10% SoC, then charge for 30 minutes, then see how far you can drive until SoC is back at 10%. The one that can drive the longest wins.

This video clearly shows me Roman doesn’t really knows what he is talking about. Range is the relevant metric. And there is a big difference between energy kWh an power kW.

Correction to the 1st part of the video. When he says "welcome to world of EV's" no sir....welcome to the world of non Tesla EV's

Road trip with family charging tablets and phone. Also stop rest area in a location with no charging station. No way it's just about miles if you're thinking about your Family's comfort

If you try to road trip an EV, there's one word you will become VERY familiar with. ANXIETY!

I want to see towing a boat from house to lake and back during summer. Also, house to trail and back 2 snowmobiles during winter. How far away and back can you go on home charging? How does real world conditions limit you.
