@Jason Gordon I just drove from Southern CT to northern VT. Left with 90%, had to charge twice and Never saw more than 120kw on a 350, and 85kw on a 150. Luckily there was a level 2 charger where I stayed to make the trip back only equally as painful as the ride up. It took 90min more than it did last time I drove up with my ICE.

Our family has or does own all 3 E-GMP vehicles and 5 in total (the GV60 due to the EV6 getting totaled by an elderly driver that should not have been on the road). 16-85% in 17 mins is probably the best net charge in an I5. Always good period in summer if the 350 chargers are working. But even in winter (22F) I did 31 mins 12-80%. The bottom line after thousands of miles and lots of road trips: E-GMPs charge GREAT!

Thank you Tom for the in-depth analysis videos. Should I expect a 2023 EV6 Wind RWD with the 77.4 kWh battery to have similar charging curves as your test of the 2022 EV6 GT-line?

[@MachE_Mutt]

Love your 70mph and charging tests Tom! Have you ever used Car Scanner to record a charge session? There's tons of interesting info. For example, I see the same slight increases in charging power on my Mach-E using a 150. It is requesting 395v, +or-, for the entire time and varies the amps to control the charging power. The EA unit matches the requested amps very closely. However, the charger output voltage steadily climbs from about 350v at the start to about 380v at the end. This was for a 40 to 80 session, outside temp 86, battery temp 91F to 100F. I see the same thing on an EVgo 100 where voltage starts about 350 and then levels off at 380. The Pro version ($5) lets you graph any of the data on one chart so it's really easy to make some quick comparisons.

[@johannel8104]

Thanks Tom. That's an awesome result 👍

[@ingoldsby]

Just something to note. That 32kw charging when it is throttled may in fact be the charger itself. That is what the EA cabinets throttle to when the cable is overheating. You will run into this frequently where some cables will only charge at 32kw because their temperature sensor is malfunctioning. Switching to another cable will then allow full charging speed.

[@COSolar6419]

I rarely use DC fast chargers on our Ioniq 5. The last time I plugged in at 50% SOC on a Electrify America 350 kw charger. The car was taking 240 kw almost immediately and stayed at that rate until 60% SOC. It then dropped off to 125 kw until around 80%. I don’t think I would subject the battery to that on a everyday basis it’s good to know it’s possible.

[@COSolar6419]

@Defective Degenerate I suspect that applies to all EVs and the type of driving most people actually do.

[@JohnGeorgeBauerBuis]

@Defective Degenerate exactly. People without access to home or workplace charging and drivers of taxis/livery or delivery vehicles will be the heaviest users of DC Fast Charging stations.

[@andrewt9204]

This is also probably a function of good thermal management more than voltage architecture. These "small" battery packs don't benefit too much from higher voltage as each individual cell will be hitting its full C rate regardless, creating heat. But it does potentially decrease the sizing of wires needed and certainly the cooling of wires from the AC/DC converter all the way to the battery. I wonder what the throttling point of a Tesla is at 200+ kW. When it peaks at 250kW, it only stays there for a few % before backing way down. Meanwhile the cooling fans are going full speed trying to cool the pack down. As for this car, I have a hunch that those slow moments might have more to do with an absorption time to determine a more accurate charge level. Ripping at that high level for so long will tend to cause false voltage readings. Either way, this is a great charging vehicle. I wonder if they utilize better pre-conditioning than the Ioniq 5? I haven't watched any review videos of the EV6 yet.

[@Dqtube]

Don't forget the charging station. Also there is a thermo mamagement. It's easier to handle 300 amps at peak for a longer period of time than 500 amps.

[@techyjames1945]

That is very good charging rate. Less than hour for full charge. Definitely seems that the 800 Volt systems are proving their advantage at fast charging. 10 to 80 is what I tend to use on the road with my Tesla.

[@theblubus]

There must've been some updates in the year since this video was made or maybe it's a difference between the GT and the Wind trim levels. But in our '22 Wind, we didn't see that charging rate drop off down to 5kW after the bulk running at 230kW. The highest we've seen was 235kW on Electrify America. At 80% SoC, our car will drop down to about 150kW and will gradually lower to about the same 119kW you also saw. We were making long 70mph 4hr driving stints in 90F weather with the A/C set to 71F and the car fully loaded with people and luggage. We also were using Android auto so there wasn't any battery conditioning before we arrived at the public chargers. Overall charging times were spot on with about 13 minutes on average to charge from 15-20% to 80-82%. It would finish before the 4 of us could get out the car, use the bathrooms and get back to the car lol

Tom, you are the EV battery professor! ☺️ Too bad the EV6 cannot prevent thermal throttling even when starting at 10 %, but Hyundai had another claim: 20-80 % in 15 min, maybe this heats it up just the right amount. Taycan seems to have a more capable cooling system, so the slowdown only comes at 80 %. The later drop to 3-4 kW with Kia/Hyundai for about 2 min. is often claimed to be for battery checks and to prevent plating. 🤷

[@MbT379]

[@ArtiePenguin1]

Not a bad video, but Tom I really wish you'd use an OBD2 adapter. It would be really helpful to see technical data like battery temperature, voltage, and amps coming in from the charger. Just recording the kilowatts shown on the EA station screen really isn't enough data. I've had a hard time finding EV6 DC fast charging videos with the aforementioned technical data on KZbin.

[@repairvehicle]

Do you have video that shows which cars can be charged with ccs1 charge port?

[@EVZacOfAllTrades]

Tom, you should do an advanced video E-GMP deep dive of 500V charging capabilities. Don't know if you know of any high-power 500V max stations in your area but I think this will be important if/when Tesla opens up their charging network as at least the V2 stations cannot match the battery voltage here. I'm unclear if the V3 superchargers can go to the higher voltage, the systems appear to be rated to do so but also software limited as of today. My understanding based on some EU testing is that the platform can accept up to 230A at 450V which will give just over 100 kW, but not sure if that's the same for the Ioniq 5 and EV6 nor if there are differences between the EU and NA versions of the vehicles. I've also heard that the RWD and AWD vehicles may actually have a different charging capability on a 500V system as the RWD vehicles have a larger rear inverter and can thus charge faster but have not seen that confirmed anywhere. Will be very interesting to know how quickly the EGMP vehicles should be able to charge using the Tesla supercharger network if it is opened up here in the US! Maybe Kyle's new charger in Colorado could be set up to be able to do this sort of testing?

[@harvey66616]

At the beginning of this video, you mention range testing the EV6, but I don't see that video on your channel. Probably because YT's search feature is lousy (they should ask Google to help! Duh...).

[@larrybehrendt4256]

It bothers me that the EV6's BMS cannot keep the battery at an acceptable temperature during a normal DC fast charge, and has to dramatically throttle the charging speed to keep the battery from overheating. Understand, this is not a case where a battery gets toasty because the outside air temperature is hot or because the car's been driven aggressively. This is a case where the BMS is itself overheating the battery, then dramatically throttling the charging speed to compensate. It looks like the EV6's BMS was not designed with sufficient battery-cooling power to handle 800v charging speeds. Yes to the idea that a good warranty is important, but the typical good EV warranty does not kick in until a battery has suffered more than 30% degradation. Most EV drivers would want to take steps to avoid this much degradation.

[@nicholasbegley645]

@@larrybehrendt4256 I think Tom is mistaken on the thermal management. I have read the drops are related to cell balancing and ensuring an accurate measurement of cell voltage. That is why the drops are very consistent on their timing.

[@larrybehrendt4256]

@@nicholasbegley645 I spent a few minutes on an EV6 forum, and they're agreeing with you that the drops are due to battery equalization. Which is still strange IMHO, because all EVs have to cope with battery equalization and I don't know another car that requires sharp drops in charging power to manage this task. What happens if the driver simply ends the charging session just before the programmed equalization was about to occur? Tom's report goes with some I've read about occasional post-charge power throttling with the EV6 and Ioniq 5. I'm not convinced that the EV6-Ioniq 5 BMS is all that it should be. Then again, managing an 800 volt architecture like the EV6 may simply throw a few things at us that we're not used to yet.

Thank you for all the great information I get on this channel. I have a question about my level 2 home charger. My electrician installed a Wallbox Pulsar 48 amp charger. That's what he suggested and that was what I had him install. I own an Ioniq 5 Limited AWD 77 kWh battery. Here's the problem..... I can charge my 2019 Tesla 3 at the full 48 Amps with no problem, but if I try to charge my Ioniq 5 at 38 amps or higher.it ends my charge session after only a few minutes. If I set my Wallbox Pulsar 48 A to 30 amps, it charges fine. Hyundai says it's the chargers fault and Wallbox blames the Ioniq. Wallbox says they rented an Ioniq 5 large battery car and are pointing their finger at the car. What says you? What should I do?

[@AerialWaviator]

Only one of the two events noted at 7:22, 12:32 are not thermo throttling events. The second event occurs consistantly with Kia EV models. It's appears to be case where Kia charging monitor is switching charging management algorithms. For example: both the Soul EV (2015-2019) and eNviro have the same ~82-84% dip. I believe this where charging changes from "constant current" mode to a "maximum voltage" charging mode (as cell voltage will climb too high when higher charging current is requested). If average cell voltage (or pack voltage) was graphed vs SoC% it would be clear as cell voltage (climbing to that point) would level off. The first event may not be thermo related (as is a short time span). It may be a throttling of current to check some cell specs. (example the difference is cell voltage, impedance at two different charging currents, to calibrate remaining charging curve) A charging metric I like to use, is how much SoC% (or kWh) can be added in 15 minutes. The EV6 would place very high on this list vs. other BEVs. NOTE: two 10-15 min charging stops will add more miles (km) compared to a single full (95%) 40+ minute charging stop. (13:22) This something to consider when traveling, as would effect travel time on longer journeys.

[@skyfox77]

Thanks for a great video, I have an important question, was the car on with cooling/heating inside the cabin or was it off? It is a known fact by now that the EV6 uses the same cooler for cooling the battery AND the cabin. So if you where cooling down the cabin at the same time it would not be able too cool down the battery effiecently.

[@stefanmosiek3873]

Is it the vehicle doing it or the charger station it self? That much power the power supply maybe getting hot

[@StateOfChargeWithTomMoloughney]

[@wasabi521]

I have had different charging curve experiences than this. I typically get 172 kw from the 150 kw ea stations flat from 5 percent to 70 percent and then ramp down to 130 or so to 80 percent where it does the Kia siesta calibrating bms. I’ve never had a charge session sit below 150 so it’s possible that’s a charger issue. My best 350 kw session I pulled in at 48 percent and got 230 kw until 65 percent and 180 to 70 percent then gentle ramp to 145 around 80 percent. Both station and car thermals playing a role.

[@wasabi521]

I love how the car can sustain high charge at high soc and is essentially thermally limited so you can add that peak rate for about 10 minutes if you plug in dead or at 40 percent soc.

Yeah, I was trying not to imply that this is exactly what others will experience. There are a LOT of other factors, from the charging station's available power, to temperature...

@Will Saba ... I've only connected to a 350KWh charger once and received 220KW rate max. I usually use a 150KWh charger since, cost wise, it's less expensive vs a 350 charger yet can get up to 180KW rate out of 150KWh chargers.

Interesting, it is too bad the manufacturer don't publish the charging rate programs, except it would put Tom out of the business. But, until that happens it would be cool to see if the manufacturer changes the recharge rate to match the battery chemistry. We know the Turnery batteries have to be slowed down in steps to preserve battery life. But if you didn't care about battery degradation could you stay at the high charge rate to 90 or 95%.

The EV6 is substantially smaller than an Equinox EV, so it's not really comparing apples to apples, IMO. The EV6 is much sportier and orrers a better driving experience but the Equinox will offer more utility, IMO. The EV6 will DC fast charge much faster than the Equinox EV can, but home AC charging is the same. Are you sure you can get a EV6 Gt-line for $40K? The MSRP starts around $53K. Perhaps there's a huge discount at a local dealer and in that case it sounds like a great deal. The AWD Equinox starts at around 41K, so you must be piling on every possible option to get it to $60K. I see them for around $50-52K nicely appointed.

Interesting that the EV6 seems to have worse battery cooling than the Ioniq5 on the same battery. Even when charging on 100+ degree weather days, my car will hold 230kw up to about 60% and 190kw to about 78%. Usually I can charge 10-80% without any of the thermal throttle events that you experienced and the 18 minutes benchmark time is easily repeatable (in the summer, it won’t be in the winter until Hyundai/Kia enables battery preconditioning). This has been pretty consistent over almost 10k miles of use and mostly fast charging the vehicle (because it’s free!). The charging tests I’ve seen on the EV6 seem to be pretty similar to your test, whereas the Ioniq5 charging tests seem to be more similar to my experience. I can only assume that the Ioniq5 has a bit better cooling capacity. Also, not all 150kw chargers are created equal. It seems that the older EA stations can’t do 800V, so it has to run through the rear inverter on the egmp cars at around 400V. With the roughly 300A limitation of the charging port, that means it’ll only charge around 130kw. On the newer ones that can do 800V, it’ll charge at up to around 175kw on a 150kw charger.

[@laloajuria4678]

the voltage.....

[@JohnGeorgeBauerBuis]

This is the approximate maximum voltage coming out of the battery pack. If the cells are 1 volt each, it would take 400 of them wired in series to get 400 volts, and 800 to get 800 volts. If they are 4 volts each, it would take 100 cells in series to get 400 volts and 200 cells to get 800 volts. This is also approximately the maximum voltage used for DC charging of the car. Higher voltage reduces weight because it allows lighter cables, since less current is required to obtain the same Wattage. (Watts equal Amps times Volts.)

What are the potential long range implications of such fast charging times?

[@laloajuria4678]

[@JohnGeorgeBauerBuis]

Cell damage and range loss will ultimately depend upon how much actual wear the cells get, which is at least partly affected by how well the cooling system works.

[@rwjr1944]

@@JohnGeorgeBauerBuis Indeed. I am concerned about the specifics of the Hyundai/Kai products. Since I usually keep a car for a long time. Even though I would charge mostly at home, I do make a good number of trips that would require fast DC charging.

[@nealmcmillan5675]

You call the pauses thermal throttling events without showing the battery temps. My theory is that what is happening is that the battery management system is performing checks on the health of the battery that it can't do during a high state of charge. I believe that this is purposely programmed in as I've seen it in all of my high power dcfc sessions and all of the reviews on charging that I've seen.

[@pasad335]

He seems to be assuming it's a thermal event without any concrete evidence to support that claim.

[@berthogendoorn2133]

Hi Tom, this throttling is likely you had climate control on, this reduces the ability of the EV to engage maximum cooling. Suggest you try it without climate on.

[@StateOfChargeWithTomMoloughney]

The car is always powered off when I do the charging recordings. I've seen other recordings and it does the exact same thing

The limiting factor is cells which don't care about 400vs800

[@abraxastulammo9940]

Did anyone find out the cell specs?

[@caliosman]

Have you tried 20 to 80% charge curve? I think that’s more realistic than 10 to 80%

[@omelborpon3159]

From what Tom has done in the past, it appears that the 20 to 80% graph would almost perfectly overlay the 10 to 80% graph. So to get the 20 to 80% graph, just chop off the 10 to 20% part.

[@mikeyc8139]

I'm curious why you never use the plural "kilowatts". For example you say "It's pulling about 130 kilowatt". Is that technically the right way to say it? It just sounds weird... like saying "my gas tank holds 13 gallon". Just wondering.

[@StateOfChargeWithTomMoloughney]

It's technically correct to say kilowatts, so yeah, I sometimes say it wrong. But when your talking kilowatt hour in the plural, you don't stay kilowatt hours, it's still kilowatt hour. I think that's probably why my brain messes it up.

[@mikeyc8139]

@@StateOfChargeWithTomMoloughney OK. I wasn't trying to be picky or call you out: I thought maybe I was the one saying it wrong. Kilowatt hour I could see either way. You could say "I added 80 kilowatt hour" meaning the energy of 80 kilowatts for 1 hour (kW/h). But I could also see "I added 80 kilowatt hours" meaning the energy of 1 kilowatt for 80 hours (kWh). Don't mind me. This is what I do: needlessly overthink things. 🤣

[@abraxastulammo9940]

@@mikeyc8139 80 kilowatt times 1 hour is actually 80*1 (kwh) not 80/1 (kw/h). You see it if you supply it for 2 hours, so you get the double amount 80*2 not the half amount 80/2.

[@johnpoldo8817]

The thermal throttling suggest their energy management system is “reactionary” vs preemptive. When it detects too much battery heat, power is throttled down, and battery cooling initiated. When batteries are cool enough, the higher charge rate resumes. I think Tesla has preemptive battery cooling so this dip doesn’t occur. An over the air software update could easily fix this. Hyundai engineers should have done a better job, IMHO

[@cordkretzschmar5693]

To get 10-80 % in 18 minutes. Your Battery should have about 20 C at the Start. It will get ca 185KW . After 2-3 Minutes the Battery reached 25 C and get the Max. of 230 KW. After about another 16 minutes it will have 80% . When the Battery becomes hot the KW drops. So if you start with 25C or more the Battery is hot to early. After 15-16 Minutes. And of cause if it is very hot or cold outside you will not get a perfect Charge. Thermal management is not perfect.

[@coreystrait4246]

I'd love to see battery temp during this. I'd bet the charger throttled down to 35kw and not the car.

[@JamesWolff]

There is a theory that the dip around 80% is not thermal Throttle but it's a BMS calibration. I seen it happen many times at different SOC stating points

[@jerrybial5082]

Could be, but why? if the vehicle isn't overheating, why not just continue at the same power? After a few minutes it bounces back up so it would be strange if that's the strategy

[@StateOfChargeWithTomMoloughney]

It's possible, but why? If nothing is overheating, why not just let it charge at the same power? If the power continued to be low after the drop I could understand, but why after 4 minutes does it go back up to the power it was delivering before? It can only be to cool off the pack or a component

[@ScubaSteveCanada]

@@StateOfChargeWithTomMoloughney This comes back to the Kona EV battery fires. One of the "fixes" was to have the BMS check the cell balancing and they kept this in the EGMP platform as a check. Of course, now they know the fires had nothing to do with the BMS.

I was surprised to see that the KIA only drew 130-140kW on the 150kW charger. My Lucid GT regularly gets 170+kW on the EA 150 units, when they are working correctly. This had led me to assume that the 150kW stations were more limited by amperage than wattage. I expected a similar performance from KIA's 800v battery.

7:25 the charge curve is not because of the 800 volt architecture. It's just how they programmed the cell parameters into the BMS.

The fact that it can accept over 200 kW for such a long time is absolutely due to the fact that the battery uses an 800-volt system.

No they didn't say don't charge your EV. They asked not to charge from 5pm to 9pm - that's much different than what the news is portraying. EVs are a "shiftable load", so you can select when you charge, they aren't like a refrigerator or air conditioner. Most people charge overnight, when electricity is plentiful.

Most people charge at home where it costs much less. For instance, it costs me about $18 to charge my EV at home and I can drive 300 miles on that - WAY less expensive than a comparable full-sized SUV (I drive a 7-seat Rivian R1S). I only use these public chargers a few times a year when I'm on a long drive and when you do that you don't charge to 100%. The car in this video can charge from 10% to 80% in under 20 minutes.

Ok. You obviously don't live in California. At $.48Kwh or more. $15.50 to charge a 2018 Nissan Leaf for a 140 mile trip on a 40Kwh battery. My friends all complain that the price is to high here to own an EV. But then again, gas is over $6.00 per gallon here also. Some states only charge .13Kwh compared to CA at .38Kwh. There is just no savings in this state on anything.
