2024 Chevrolet Equinox EV DC Fast Charging Analysis

[@StateOfChargeWithTomMoloughney]

Note. @36:22 the Time to add each 10% battery chart is incorrect. On the 20% to 80% recordings it took 8 minutes to go from 70% to 80% on both stations, not 16 minutes as shown. The total time as 34 mnutes on both charging sessions. Hat tip to e-redj for noticing!

[@robertl2655]

The full charging time chart still shows 45 minutes for 10-80% or 223 EPA miles (FWD) or 200 EPA miles (AWD). Adding this number of miles in a Hyundai/Kia or the new Tesla highland would take half that time (or less). Even my crazy inefficient 2024 R1T DM large can pull more range in less time than the Chevy! Tom, you talk to these guys.... why can't GM get EV charging right? For years they sold the Bolt brothers with crippled fast charging and now they seem to be once again introducing a vehicle with charging that is two generations behind. Why does GM struggle so much with this?

What is the absolute best choice for the 2024 ford f150 lightning flash

[@carsonassociates3263]

It seems that DCFC rates come down to two things: maximum current capability, and pack temperatures during charging. Our vehicles don’t “request” kW during DCFC; they request a level of current (amps), and reduce the current requested when the pack gets too hot (and as the pack voltage rises to maximum SOC). It would be interesting to see the same test done at ambient temps of say, 40degrees. Would the colder air temperature allow 500A charging to be maintained for longer before thermal throttling?

[@carsonassociates3263]

@@joamiggDepends on beginning SOC and charge limit. Tortoise and the Hare: definitely faster charging “sprints” from a DCFC capable of 500A (the Hare), but if the battery pack heats up quickly and reduces the amps requested, the “slow and steady” 350A (or less) Tortoise might actually be just as fast, especially for a deep charge (like 10%-80%). For a quick 20%-50% charge, the 500A is the faster choice.

Was gonna come in guns blazing and telling you to stop listening to Kyle, and that DC speeds don't mean as much as he says. But then I watched and realise...yeah...that really is kind of slow. Maybe 150 kW is still okay for a 2024 model year vehicle, but only if you really can use 150 kW. Thanks very much for all the time you're spending and the good reporting you're doing for us.

[@kens97sto171]

The speed is not as important as the curve.. On that 350 session.. imagine if it did not de-rate.. and just had a smooth curve down to meet the 80% drop off curve. Would be a totally different result. BTW Kyle talks about the curve all the time.. and that peak speeds don't matter that much.

[@JonVB-t8l]

@@kens97sto171 When I road trip, because I drive a Tesla, I regularly arrive at a charger with 5% or sometimes less. (never concerned about them not working) In fact I sometimes speed up to arrive lower and maybe save a few minutes off my drive time. When you start at 5% you get that peak 250 until like 20% then I'm still at 170 by 50%. The best part about those peaks though is, my home is 40 miles from a super charger North or South. 45 miles charging at 1100mph is like 2-3 minutes, and I finish charging at home. It's literally faster than gas sometimes. This car charges too slow for me, but I'm sure people who don't road trip will be interested. It's just a bigger bolt in my opinion.

True. This highlights how unimportant DC fast charge times are for many folks. I only need to use a DC fast charger once every month or so. I don't mind waiting 15-20 minutes longer when I do if I have to. But those who rely on DC fast chargers may look for faster charging options.

I recently took a trip in a LYRIQ and only charged on EVgo 350s. I got good speeds at all but one, where there was a nose dive like you showed on the 350, that slowly recovered. Was a bit of a bummer, but we were eating lunch, so actually kinda nice. Anyway. GREAT video. Terrific content. Loved watching.

[@billjohnson3344]

Based on personal experience with the Lyriq, your ok charges (no Ultium dip) were due to not dipping nearly as low as SOC as Tom did. Most people will hover around 20%, your road trip didn't go nearly so low (assuming you mean your recent video). Will be interesting to see all of Tom's upcoming charge sessions and differing SOC's. But might be hard to fully qualify given different ambient temperatures.

[@devoe4096]

Same. It would be different if I could have a home charger.

[@RyanTobler]

You nailed it stating people want a consistent/reliable charging experience even if it’s a slower speed to manage thermals better. It’s crazy how the charging curve can be all over the place with no rhyme or reason. Can Chevy really fix this with a software update? I do have to say the few times I’ve fast charged I saw more consistent speeds on a 350kw charger. It would jump to 150 for about 10 minutes and then drop down into the 120s. That was in Barstow/Bakersfield 110+ heat going from about 20-60%. I did have one time where I got throttled to 30kw after about 8 minutes but I unplugged and plugged into a different charger and went back to the 120s.

[@josephgallagher1440]

Hi Tom, thanks for sharing and providing your analysis! I have a 2024 Nissan Ariya Platinum that can charge up to 130 kilowatts. I performed my own testing on a EVGO 350 kilowatt fast charger and 100 kilowatt. I found that on the 350, I got to 127 max when I was around 20 percent and then gradually stepped down. It took about 28 minutes to go from 20 to 80 percent. Whereas on the 100 kilowatt the max was 75 and gradually decreased and took 40 minutes. I have noticed that the Ariya has been pretty consistent on the charging speed and step down voltage/kilowatt charging.

[@davidroddini1512]

So what I take from this is that for the Equinox, if you’re charging up to 80% it makes no difference whether you use 150kW or 350kW. In fact you might even charge quicker on the 150 due to thermal limiting on the 350. So you might as well just use the 150 and save the 350 chargers for vehicles that can take advantage of the higher speed. However, if you *have* to charge all the way up to 100% then the 350 will save you several minutes of charging time to reach 100%

[@davidroddini1512]

I personally like the charging curve as it encourages drivers *not* to use the 350 since the Equinox actually charges better on the 150.

[@bfvader]

Probably better for the battery in the long term to not have it bouncing off the temperature limit too...

[@RyanTobler]

I saw more consistent speeds on a 350 than he did. Mine got up to 150kwh and dropped down to the 120s for most of the charging session (20% to 60% range) and this was in 110 degree weather.

[@greenne]

​@RyanTobler yeah Tom is was having thermal issues...that is not a normal charge curve for this vehicle

[@Comfort031]

I haven’t had much luck on 150kW chargers. Some of them have trouble putting put the amperage needed to charge at a decent speed with the equinox’s pack voltage being so low

[@steveallwine1443]

I feel like you really need to use an OBD dongle and ”Car Scanner” to also follow along with the battery temperature and module temperature during charging. You should be able to precisely determine the temperature threshold where de-rating will happen.

[@ClarenceDold]

CarScanner and an OBD would allow monitoring the battery temperature. It also shows SOC, coolant pump RPM, DC volts, DC amps, and kW on my Bolt. It sounds like Tom is estimating the current draw based on the SOC% and a known battery voltage value. Maybe Carscanner can't be used for commercial endeavors. Other than that, it seems odd not to use it. I don't like the logging in CarScanner. I need to write a coalescing program to capture all of the data on one line. Tom could use video capture or screenshots.

[@eddysaad]

Great video and thank you for pointing out the issues with the EVEQ charging system, hope that GM take them into considerations. One of the issues I have with the video is making it a real-life scenario during long weekend trips. The 2 scenarios I'm looking for are a 150-to-300-mile range (or a range that tests the EV maximum EPA estimates) and scenario 2 is driving a longer trip 300-to-500-mile. While charging speed is important, most EVs owners have some access to home or work charging to replenish the miles used on daily or weekly basis as overnight charging is adequate to keep the EVs at 80%. What I would like to see is covering the scenarios above with multiple EVs and evaluate the total trip time, including charging time, the level of comfort in the ride, actual time lost due to waiting on charging, especially if not taking a break for bathroom runs and snacks/meals. From a theoretical perspective, using ABRP planner, the EVEQ is almost identical to Tesla MYLR from a total trip time perspective for a 300-mile road trip while the Ionics 5 RWD LR, takes 20 more minutes (assuming 100% state of charge leaving and arriving at 10%)!

[@mannyman4103]

I never precondition my Rivian R1T before fast charging(In the summer here in Arizona...) because it'll charge at 220kW for 3 minutes and then derate the EA chargers down to 40kW and it never picks up again. I love it when the charger only gives 150kW because it stays at 150kW all the way to about 60% and it's a lot better than thermal throttling..

TOM! Another great video. Wow this is an interesting one. I think it puts a little polish on the idea that A 150 kW max car should never use a 350 kW charger. It’s a small piece of the puzzle that is the EV charging landscape. It seems like there’s always something new to learn. Can you start a series on EVSE that do not have a built-in cable. Or it would be great to see a series that focuses on better charging options for multifamily, housing, and public charging options. Best for small businesses. Tesla has their destination network, which is great, but they ask you to install a minimum of six destination chargers as part of their application process. I’m sure they just don’t want to have Tesla drivers show up to a small location expecting a charge and then there are no available destination chargers if the business has only installed one or two, and it seems reasonable that if you could just buy a Tesla wall connector and add it to the destination charger map, it would be overrun with single units Everywhere as small businesses game system by getting on the national map with only $1000 investment. I have friends in the middle of nowhere in Kansas and they want to start offering EV charging, but I know it’s complicated based on states that don’t allow you to sell electricity unless you are a large scale provider. I think a solution would be to rent the double ended cables as needed for a small charge. I feel like it would also help keep the units much more undamaged. Maybe you could sell an online course for $25-$100 that explains everything someone would need to start that small business. I know you had a lot of problems with your DC fast charging equipment years ago, but maybe there are new products on the market that could really help a small business at least offer this as an amenity

[@newscoulomb3705]

So maybe it's just me, but I actually don't see the problem here. Yes, there are some improvements and tweaks that need to be made to the charging profile, but given how fresh the model is, it's not bad. For reference, if you plugged these numbers into Out of Spec's "10% Challenge," the Chevy Equinox EV would still be on par with or even beat a number of EVs with "better" charging profiles like the Tesla Model Y and VW ID4. Also, for a model that is being pushed for current and former Chevy Bolt EV owners, you try selling those customers on the idea that charging from 20% to 80% in 35 minutes or driving 500 miles at freeway speeds with only two 20-minute charging stops is somehow "bad." For people who rarely if ever drive more than 300 miles in a day (at least 75% of the population according to BTS data), this really is a non-issue.

[@G-Rated]

It’s not just you. People are overly & hyper critical of *gm’s* Ultium platform in their very first generation and with their very first models. They simply won’t get the same grace that Rivian, Tesla, nor Ford has received even for the same exact things like ridding their vehicles of Apple CarPlay. People are extra critical of General Motors in everything they do and this seems to be a problem for reviewers. I think reviewers have higher expectations for GM than they do for Tesla and Ford but that will only further the gap making *gm’s* products better than the competition as time goes on.

I'm sure many more charge tests are to come. Personally I haven't seen the GM dip yet and if operating normally (no thermal) the Equinox will do 10-80 in about 35'ish minutes. I've seen this repeated on several Tesla Superchargers(magicdock).

Try leaving the AC on set to like 68F... I found on my Bolt EV a slight improvement and different behaviour when charging with the car ON.. but AC off.. vs Car ON and Ac ON.. about 3-5 KW better. And when the car is off.. a similar result.. I think the car waits too long to start cranking the AC compressor for cooling. The Equinox may be doing the same thing.. It de-rated soon when on the 350kw... the de-rate happened later on the 150.. but then happened anyway... it seems the cooling programming is waiting a little too long to start going. rivian has this issue also a bit. Great video... defiantly seems like just going to a 150 station is best.. no need to take the 350 just to save 5 min.

[@jeffreywilhite1071]

I have the same Equinox EV 2RS as you Tom. I’m not seeing the thermal throttling when using the EVGO 350’s. Today I went from 40% to 80% in 17 minutes. When the session ended at 80% I was still pulling 91kW. It was a steady decline from 156kW. Did you precondition the battery? I don’t believe you mentioned that. This may seem strange, but I feel it charges better today than it did when I first got it. I have 12,500 miles so far. Look forward to your future Equinox videos.

[@StateOfChargeWithTomMoloughney]

How cool was it where you were charging? The warmer it is outside the worse the thermals will be, preconditioning or not

[@erikstephens34]

I was just going to comment the same thing. I have a LT Blazer EV with the 10 module Ultium Battery as well (85KWh). The biggest station I have charged at was a 200KW rated station at 350A. I used the precondition function upon navigation to a DCFC so it would have fully pre-conditioned. I charged from 14% to 88% and I was pulling a similar 110+KW at about 50% SOC and I was pulling 88KW at 80%. The ambient temperature was 86F (30C).

[@lawrenceasero2207]

If my math is correct you can add about 150-175 miles of range in 1/2 hour. Given the 300 mile range of the Equinox, you can drive 4 hours then break for 1/2 hour to go to the bathroom, stretch your legs, charge the car, eat a snack. So I would say a 500-550 mile road trip is comfortably doable in the Equinox. Anything over that would make the slow charge times a problem. Would be interesting to know who actually takes a road trip where the drive more than 500 miles in a day.

[@billjohnson3344]

What was the ambient temperature for each of these charges, and how long did you precondition? Both seem to be a big factor in whether you see the thermal derate. Hope GM responds to this - all the Ultium vehicles showing this dreaded 'Ultium dip' when charging at high power, low SOC, and mid to hot ambient temperature. People in very hot climates seeing even worse, with propulsion limited and turtle warning lights, and A/C switching to blowing warm air during the charging.

[@BrianLangeProper]

Also curious about this! Also- in winter ambient temperatures, would we see a bigger gap between the performance of the 150 and 350, and by how much 🤔

[@ChuckvdL]

Tom, the other big users of DCFC are folks who cannot L2/L1 charge where they park. So the speed of fast charging can be a big factor to their buying decisions as well. It’s a less than ideal (and far more expensive) way to go, but many folks have no access to charging while at home/work/commuting. It can make a difference between 15-20 minute sessions (same as a busy gas station) or taking well over an hour or more. I’ve found that when cars charge slow they are more often (ironically) fully charged to avoid having to charge more often.. people will go eat dinner, or shop, and just leave the car at the DC charger for an hour or more.

[@StateOfChargeWithTomMoloughney]

You're 100% correct. An EV isn't the best choice for everybody, and if you cannot charge at home or work, you need to make sure the charging times will fit into your schedule, as well as the available charging locations and their usual utilization rate (are they frequently full). The Equinox will likely need 10-20 minutes longer to charge than other comparable EVs, so if that extra time waiting each week is a problem, then I wouldn't recommend getting it. However, currently, only a very small percentage of EV owners can't charge at home or work. That is going to change, though, as adoption rates increase. Owners need to do their research and know what they are getting into before buying and finding out it doesn't work for them. I hope my videos like this help people better understand how long they will need to wait when charging.

[@havnfunb4]

I would like to see you do a 30-80% on a 350kw charger as I have been finding it takes 25 mins or less with the charger hitting 158/159kws each time on Electrify Canada stations and holding that or just under 150 for a few mins before dropping to a lower charge. Not sure if preconditioning helped but I always try and do it prior to going to the station. Weather is a bit cooler up here also 😊

Nice call outs Tom! It’s really sad that my 2017 Bolt charged faster back then vs 7 year newer Chevy EV. Seriously?!?

[@StateOfChargeWithTomMoloughney]

It depends on where you charge. I charge at home 95% of the time and it costs me $16.00 to fully charge it at home. if you use public fast chargers, the cost is comparable to gas, though. Don't use public fast chargers unless you need to.

Great points Tom. I agree on your observations of the Lightning being repeatable and expected. The thermals are sorted on the Lightning. Would love it if Ford can find a way to bump the charge speeds. I saw a post on X that the 2024's are pulling 500a in the boost phase. Would like to see what that means in your charging curve tests. GM had lots of time to sort out the charging and thermals here and every one of the Ultium products the charging is still screwy and unpredictable. Not a good feeling and clearly not optimized. GM needs to get this sorted out.

[@MichaelW-kx3wz]

Tom as a fellow numbers geek love your videos - quick request could you do the same test with the new Ioniq 5 -

[@hieyeque1]

The limiting factor on extremely high KWh throughput is often heat. If you are trying to get as many miles as you can in a short period of time, heat is not an issue. Suppose you charge for 10 minutes at a high rate of charge - that will work for you. However, if you are trying to do a long charge session, a slower charge rate will often have a faster completion time because it can maintain a higher average. I saw this on my Tesla Model 3. I was graphing charge performance and found that the car did better when it stayed at 80 to 100KW as apposed to hitting 170KW and getting hot. Then it would drop down to the 40's and 50's later in the charge. For road tripping, long charges were required and thus, I wish I could select a slower peak charge, for a faster overall experience.

I am interested in seeing your future 10-90% charge performance test. Could we see the "charging power graphs" for the 20-80% charge sessions? I also think that it would be interesting to see a 20 minute charge and range test for between 0-60% and 10-60% battery life, ie, before the initial thermal de-rating occurs.

[@smartelectriccar]

Amps!! My F150 Lightning charges slower on lower amperage charging stations. The KW nameplate on DC chargers doesn’t help me choose what would charge my truck best.

[@jghall00]

So basically, drive 150 miles, stop, charge, repeat? The biggest saving grace with this curve is Supercharger access. If I had to stop frequently relying on EA, no way I would risk it. Too many derated, congested, or out-of-service chargers. GM really gimped the charging on this thing. Was it really necessary to keep the cost down?

[@brianbeans2190]

Just further proof that in spite of all the Ultium hype from GM their EV engineers are still taking stupid pills when it comes to fast charging. This thing DC fast charges as slow as my 2017 Bolt EV! No improvement whatsoever. Funny thing is the Blazer EV 100 kWh pack isn't really all that much better as far as I can see from other reviews. It'll do it in 37 to 40 minutes, on a 350 kw DC Fast Charger?? Really GM? I really would like to lease the Blazer EV too. I love the styling, it's looks. Looks like a car a man would want to buy, but with this slow DC Fast charging? They must be smoking dope.. SMH man. They do not learn. Guess Nissan and Hyundai are going to be my only practical choices for my next EV. I do take roadtrips, so DC Fast charging times matter. Thanks for this informative and insightful review. Oops! Take that back about Nissan. Just checked their fast charging times. No-ooooh! Does it in the same time as the blazer. Okay, I guess it's looking like Hyundai or Kia win the DC Fast charging prize. I've spent too much time at DC fast chargers in the Bolt to ever want to settle for another slow fast charging car. I'll buy a plug in hybrid first. Never again with the slow DC Fast chargers. I think Hyundai Kia raised and set the bar. The rest of them better play catch up. Peoples time is precious. They seem to understand that in a way the other ev makers don't. No way in hell I'm buying Elon's anti-union shop fascist-mobile either. That guys been a real disappointment in terms of personal character. Not buying anything with his name attached to it.

[@l10industries]

My dad and I made a cross country road trip from Missouri to North Carolina. He has a 2023 Bolt EV and I have a Hyundai Ioniq 6. He literally spent several times as much time as me at charging stations. My average stop was 10 minutes for the trip while his was close to an hour. It is a real game changer in terms of roadtripping. I don't know why no other legacy American brand is taking DCFC seriously. Hyundai Kia Group beat them up for their lunch money and are eating their lunch. I wonder what sort of technical differences there are for going 800V (800V class.) Why hasn't literally everyone switched yet?

[@rossm9200]

I did the math before swapping my EUV for an Equinox. Even with the change in efficiency and the Equinox's mediocre charging curve, DCFC with the Equinox was considerably faster. I can't remember the numbers and I'm too lazy to redo the math, but I believe it was approximately 33% faster.

[@G-Rated]

But I can't do anymore slow DC Fast charging, so I'm going to have to compromise somewhere. I like the utility of a hatchback, but I'm not doing anymore 1 hour dc fast charging stops like with my Bolt. Screw that. I'm all or doing my part with switching to ev's, but I gotta get where I'm going in decent time too. I'm just expressing disappointment in GM is all. They promised something with Ultium that they haven't delivered in terms of DC fast charging performance, and it's just ruining the decision making process for me, because what I want is a BLAZER EV! But 40 minutes for a 20%-80% DC Fast charge??!! When a damn Hyundai or a Kia can do it in half the time??!! Arrgh!!

[@Miata822]

By about 4:00 I'm already imagining the conversations between Chevy drivers and the "helpful" Taycan/Lucid/KIA drivers waiting to charge. OK, continuing the video now, but I'll be cringing the whole time thinking of the confusion this is going to cause. I'm sure GM had a reason to go this route, but the ONE thing this nation didn't need was more confusion and controversy about charging. EDIT: OK, watched. I'm sure GM will work on that wild charge curve. Great to see that website. Yes, I keep screenshots for planning trips. I have a product review request but will send that separately.

[@DumbDadDuties]

We clearly need more instrumentation from both the vehicle and the chargers. The vehicles should report battery temps, fan speeds, etc. The chargers need to provide volts, amps & kw.

[@johnanderson9735]

Great info! The charging cost here would make me not want to ‘upgrade’ to the Equinox. It would be nice if GM did more in this area, that might make this a somewhat competitive EV.

[@wolfman9999999]

The metrics make sense. The 350kw EVSE pushing so much current is heating up the system. Eventually it catches up with the car and forces a derate. GM needs to give this a look over and update the software.

[@perperers2502]

I'm glad I decided to buy a fast charging car after seing this. But I still have problems when all chargers are occupied by slow charging cars. Normally when I get access my car is charged to 80% faster than most of the cars around me even as they started their sessions a lot before me. I drive a Hyundai Ioniq5 and charge at Ionity stations if they are available along my route. On 400V chargers I don't reach half the speed I see at Ionity where I normally can reach over 230 kW for a shorter period. I believe 800V EVs are the future. The thermal limits are much easier to handle with higher voltage.

[@photogravity]

Agreed on the 800v cars. There are some folks who defend the 400v architecture as if it were a central tenet to their actual being, but I’ve seen the light of 800v and simply can’t look back, if it is a car that will be used for travel on a regular basis as is the case with my Ioniq 6. In relation to the lower power chargers, I travel through Quebec and into the maritimes on a regular basis and will often use the 100kw/400v chargers. The Ioniq will immediately start charging at 90kw (seems to be an inverter limit) and hold it there the entire time I’m plugged in. It affords me more time to stretch, get a coffee, make a sandwich or whatever I want to do without rushing to get unplugged because the charge is finished.

[@caryrae73]

I’m sure you know but we can now use GM EV’s on V3 superchargers. GM is charging $225 for adapters through them.

[@billvandermolen5907]

Not really sure that its surprising to see that 350 is as "slow" as 150. Everything I have read/learned about Equinox EV so far (from this channel especially), is that the Equinox design favors long battery life over fast charging times. As a rule, fast charging reduces battery life with one of the variables being heat. So given that info, of course GM is going to code it such that fast charging temps are really lower compared to other vehicles that may not be coded for longer battery life. For some like myself that want this car as a daily commuter car more than a road trip car, I find this a bit encouraging. I will more likely use fast chargers now at work-place stations because the heat is controlled, and fast charging is now less of a concern affecting battery life.

[@gregpochet4812]

If this car started at $$28k for the base model to $38k for the top, then the slow DCFC could be acceptable. At $35k+, I wouldn't trade my Bolt in for the Equinox.

[@johnpoldo8817]

It was a mistake to cancel the Bolt as I’ve rented several and it’s a great EV for city driving. Advantage of Equinox is size, only important if you need more cargo space.

[@EnjoyingmyEV]

Tom, Could you please do a 20%-80% recorded session on a V3 with the A2Z adaptor now that GM has access to the Tesla Supercharger network.

[@StateOfChargeWithTomMoloughney]

I will

[@scottbalak7123]

Has GM said why they chose such a low pack voltage? My guess is cost/performance trade off? I agree that consistency of experience is a must. I don't use DC fast charging much on my Lightning ER, but the couple times I've road tripped I did get better performance from an EA 150kw than an EA 350kw. In my cases I believe it was charger related; however, the 150s consistently outputted ~167kw for the 15 minute boost period and kept me maxed up to 80%. The lightning charge experience is very consistent. I agree with your statement that the common customer will view charging in terms of minutes and frankly they'll probably say anything within +-3 minutes is "the same". By the time you park, get your McDonalds, watch some youtube....who's counting seconds. IMHO....no new EV pack should be below 600V. The issue with EV adoption is not range capacity (KWH), it's charge rate (KW). If batteries could be charged in 5 minutes nobody would care they only have 250 mile of range. Also...maybe chargers should have AMP ratings, not KW ratings. Just my 2 cents.

[@KevinMasterson-se5pv]

Great info. Can we see home charging speeds at different amperage. Best for me is a 30 amp circuit. 24 amp charge . Or even at 16 amp charge 20 amp circuit

[@billjohnson3344]

This is just a calculation - no need to test. Level 2 charging is flat across the full range of SOC. 24A (at 240VAC) charge is 5.76kW, battery is 85kWh, 85kWh / 5.76kW / 90% charge efficiency = 16 hours 0->100%. Same calculation for 16A yields about 24 hours from empty to full. Most people will see much less time, daily charging to 80% and not discharging anywhere near zero.

[@LJLion]

This is why I like my SR XLT Lightning 98kwh pack, consistent charging curve , 20 min from 10 to 80%. Very repeatable and efficient thermo. I've seen 170kw for the first 12 min or so, then 98kw, then like 40kw at 80%. Nothing out of whack. 80%, time to pack up and leave. No reason to be charging past that .

What charges faster, equinox or leaf?

[@LarsDennert]

From memory, the rivian is also about 5 min difference between a 150 and 350 despite being able to pull 220.

[@peterbland7227]

Shocking (no pun intended) how far behind GM is in battery engineering compared to Tesla and Hyundai/Kia. Having said that, we’ve had an EV for two years, and I think we’ve charged away from home less than ten times. Home charging is the norm.

[@Comfort031]

I dont think its engineering per se, as in battery chemistry. Its the design of the pack, eg cells in series and parallel. The Ultium platform is modular. Lower capacity vehicles like the Equinox have less cells, and hence a much lower pack voltage than, say, the Hummer. The Hummer can charge MUCH faster as a result. That was likely a cost cutting measure so they didnt try to make any changes to boost the voltage of lower kWh battery packs. A bit unfortunate. Ive had issues with Shell DCFCs only charging my Equinox at 15-38 kW. 250 kW chargers are much better. Had I known this I likely wouldve gotten an eGMP vehicle like Ioniq 5 or EV6 instead. I dont fast charge much but I would really like to have the ability to charge very quickly on a road trip. Besides the poor fast charging, though, I am extremely happy with my Equinox. Excellent range, plenty of passenger space and cargo room. The seats are very comfortable. Its the only car I’ve ever owned that my back doesnt start hurting after long trips. Only other thing I wish it had was more power in the FWD model as its a bit sluggish on the highway.

[@bjcouche1]

When the 350KW charge station thermal limits at around 20 minutes (0-100 test) how do you know that it's the vehicle's battery causing the derate and not the vehicles charge inlet overheating? Or more likely the charge station connector overheating. Did you place the charge station in a "tech mode" to video the CCS PLC comm data in order to determine what current the vehicle was requesting, and what the charge station was providing? Remember, the charge station has no idea what the vehicle can accept, if "cells are balancing", none of that. All the charge station gets is 2 command values from the vehicle. Current request, and maximum voltage limit. The charge station can however deliver LESS current if it chooses, like if the connector pins are overheating, the cable is overheating, the liquid cooling in the cable has failed, a power module in the charge station overheats, another car plugs in and the cabinet needs to share power, etc. Without knowing BOTH the vehicle current request and the charger current provided, you don't know for sure if a portion of your observed curve is affected by a charger limit or a vehicle limit. You could try another brand (charger hardware manufacturer, not network provider) 350KW charge station, but I suspect similar results because most 350KW cables and plugs, are only rated for 350A continuous and 500A peak for about 15 minutes before they overheat and the charge station has to reduce current to let the pins cool down before ramping the current back up. Do you know of a charge station your Rivian or F150, can get 500A for more than 20 minutes? If so, then try that one with the Equinox.

[@StateOfChargeWithTomMoloughney]

I used these same chargers a week earlier with multiple Lucid Air charge recordings where it was charging at a much higher rate for longer periods without any derating. It wasn't the stations, it was the vehicle.

[@consolemaster]

Some folks want to stretch after driving some time....but, for me, the exercise of walking to the bathroom and coming back is enough. I don't usually spend 20-30 minutes charging. Therefore, ICE is still right for me. Chargers and battery tech still will be out another 10 years. I think it will start to innovate when we're closer to 2030. Currently, fast chargers are slow to expand while the rate of EV sales outpace charger development. So, I'm sticking with ICE at the moment. More freedom and flexibility. Plus, most 4 cylinders have range of 500-600 miles.

Really interesting video. Fast charging a Blazer EV, I’ve noticed a ton of heat dumping out behind the front wheels. I’d be curious to know if you’re able to meaningfully help cool the Equinox by opening the hood or maybe even using a battery powered fan to help provide some extra air flow. It’ll be interesting to see if the 350/150 difference is greater when the weather is cold.

[@garyclark6747]

Basically if you’re at 10% or greater use the 150kW charger. Use the 350kW if your at single digit SOC and you don’t mind heating up the battery to save a few minutes. 👉🏼My use case is we own one vehicle therefore my tool of choice must be a jack of all trades and the IONIQ 5’s 0% to 82% of 22 minutes fulfills the 20% of all energy I’ve taken in quite well. 🎯For us the multiple charging stops during road trips this rapid charge speed saves hours; even though it’s a small % of energy taken in over all. Although we enjoy the journey, these are nessisary miles to traverse vs a scenic casual road tour. We prefer to enjoy the drive rather than to wait at a charging stall filling time with other activities. I hope GM (Ford/Rivian/ETC) uses the current state of the market to correct these Voltage Issues. 43:41
