How Fast Does The Cadillac Lyriq DC Fast Charge?

[@vancity2349]

Great test Tom, really appreciate the depth and testing you do. Keep up the great work.

[@RichardMillet-RM]

Thanks! 20-80 tests are extremely more useful to me than 0-100.

[@jimv1983]

Both are relevant. For daily driving 20-80% is the most useful. For a long road trip I think 10-100% is the most useful.

[@TheAbcdhjkl]

@@jimv1983no, you don’t fast charge over 80% on a road trip. It’s more efficient to charge according to your charging curve when the speeds go down. Charging to 100% is something you do overnight or perhaps during a long lunch break.

[@jimv1983]

@@TheAbcdhjkl not charging to 100% on a road trip means you have to stop more often. Even charging to 100% you have to stop way too often on a road trip. I wouldn't take an EV on a long road trip unless I could go AT LEAST 300 miles (that's real world miles not EPA estimates) on 10 minutes of charging.

Hi Tom I think this the best case scenario you got. Haven't get chance to charge in cold weather yet. It doesn't do well above 100 degrees specially if you are using car AC whole charging. I did EVgo Charging session almost identical results.

Thanks for confirming. I also have since done other charging and gotten similar results.

[@highrafterranch1982]

I saw similar results about 6 months ago…. GM engineer was testing autonomous driving in a pre production Lyric on I 20 west of DFW… charged next to him in my Lightning at 2 separate EA stations while we were traveling the same way. I charged my Lightning faster both times. Thought maybe it was a fluke. Maybe not though. Thanks for the info. Also, temps were low 20s at the time ( unlike now!!!)

So I own one of these and I can confirm DC fast charging is a massive pain at the moment. I’ve been to various 350 kw fast chargers, and the fastest I’ve ever seen the Lyriq take in is 151kw. I also experienced a charging curve identical to his curve today at a 350kw charger. Basically fell off a cliff at 50% charge. Everything about the Lyriq is amazing EXCEPT the public charging. Definitely needs some software tweaks.

Hi Tom, Another very informative video. Manufacturers do not really understand the consumer, these mystery profiles baffle those of us that understand them but all owners will experience the time to charge. It is bad for sales and adoption rates. Some engineer has decided this is a good profile but you are correct, what is getting hot (if the assumption is correct) and why? Did you use marginally acceptable components? If so, the heat stress will still get to them. We just need better transparency. Manufacturers should set up websites and post engineering reports for the owners that understand the data. I would sign and honor an NDA (maybe honor is the issue). Just tell me the truth!

[@Miata822]

@ Tom, your 20-80% tests and the explanations you give are truly a service to those just getting their first EVs or trying to figure out how to get the most out of their new cars. I recommend your channel to new owners I meet at charging stops when they seem confused. Yeah, that's a disappointing result. Using your range test data that yields only about two hours of driving for 30 minutes of driving, and we all know that many drivers drive less efficiently than you do in the tests. There will be frustrated Lyric owners if this test is a typical result for the car.

[@dusty-vo8gh]

Miles added per 10 min of charging is a great metric espacially when you use your 70 mph numbers.

Great detailed test. As someone that can't charge at home this shows exactly why I won't be getting an EV anytime soon. Probably at least a decade. Not until the average charging speed is like 5-7x faster than what this video shows. For long road trips I would charge up to 100% so I wouldn't have to stop as often.

What??? It cost you $26 to charge 60% of the battery which gives you about 190 miles of driving/range, so about 3 hours of highway driving (if you drive at 65 mph) which means $9 per hour driven on the highway. Add 33% for a non + member you are at $12 per hour of highway driving. Am I getting it right? So if I travel across the country and cannot charge at home this type of EV will cost me about the same in "fuel" than my current 2019 Acura RDX gas suv does?

[@bhmbill]

Wonder if it would charge differently at the Tesla supercharger with the adapter.

[@chrisprice1603]

Thanks for the great video, many drivers would substitute a slower speed for more range and fewer stops. Your test suggests a 3.3 mile per KWh and that is not shabby. Perhaps that number could go up a bit at between 60-65 mph. I drive my motorhome at a constant 55 mph and find it is more relaxing and you conserve quite a bit compared to 70 mph, should be the same for an EV?

80a@240v = 19.2kW or ~18%/hr. 48a@240v =11.5kW or ~11%/hr depending on onboard charger (and EVSE) maximums. Possible slight speed taper at very top of pack, someone will have to test but usually negligible in total charge times. You shouldn't see any taper in the meat of the pack.

When it bottomed out around 50% how many other cars were on the same transformer feeding the charger?

[@lllsevlll]

That drop in the middle was some kind of issue with that particular vehicle. I have a lyriq and never saw such drops during charging. it gradually reduces the power and hits 100kw at 80%. It goes down quote drastically after that. Did you do the pre-conditioning before charging?

[@user-do7ui9he9d]

Just traded in Tesla for 24 Lyric lux3. Tried the 240v home charger on a 14-50 outlet in my barn: but is limited to 20 Amps, so pops the ckt breaker.

Any input that this charger w/ current settings will work OK?

[@TrainsFerriesFeet]

Tom, do you plan on doing a charging curve for the 2024 Polestar 2?

[@igiveupfine]

is there any reason you don't look at the output of an ODB reader app while the car is charging to confirm if WHEN a cars charging rate drops, it's due to a high battery temp? and, i would say, you don't have to report the temps, because different manufacturers could decide to drop charging rates at different temps, that's fine and up to them. but i believe you or someone else had previously said a manufacturer previously designed their charging curve to just ALWAYS reduce charging speed at 15 minutes, no matter what the battery temp was. and you could see that if you looked at the ODB reading of battery temp.

[@trustbuster23]

My Makita power tool batteries get hot as they discharge, as well as when they charge. The smart charger for those batteries senses the temp and holds off on charging until the pack temp is low enough to safely recharge. This is the exact same chemistry. Warm summer day + using the AC for cabin cooling as well as pack temp control probably means the pack temp was near the higher end of the acceptable temp range when it was plugged in. In winter I expect the curve would look very different. Also remember that GM was super conservative with the charging profile for the Volt because they didn't want to buy a million people new batteries given the long battery warranty. This may be a similar situation where they are being very cautious with the new battery platform until they are confident it won't bite them down the road. Honestly, I think the most valuable charge curve would be what you see after driving on the highway from 80 to 20 at 70 mph. That is the scenario where charge speed will matter most - a long highway trip where you need to do 600+ miles a day.

[@wingdwolf56]

My Blazer only tells me miles per kwh as it’s charging. Also, how do you determine how much you home charging is costing

[@nthused]

Had high hopes for the Ultium pack. They’ve either got a sensor in the pack giving incorrect information to the controller or the cooling in the pack is insufficient (my bet is on the sensor or the controller software. The curve dropping so dramatically so early cannot be engineered to do so by default.

[@MrNicholg]

A 20% to 45% charge in 10 minutes is 150 miles of range added according to the previous 70mph range test. That's over two more hours of extra driving with a 10-minute splash. Assuming you start with a full pack, that's 420 miles of driving. Nearly 4 hours followed by another 2 hours to get to an overnight destination. That's like going from San Diego to San Jose, or LA to Phoenix with room to spare. How often does anyone do this? Once a year? That's a shit drive no matter where you are, but easily doable with a 10 minute charge in this thing.

[@eddiegardner8232]

Very strange charging curve. Looked like a "thermal event" as you said when it dropped precipitously. Perhaps they can pre-cool the battery when a charging session is predicted by navigation software to a charger, in anticipation of it heating during charging. Or something like that. The 0-100% charging session will be interesting.

[@dmunro9076]

The Lyric charged from 20-52% at an average of ~165kw versus 20-52% on the Lightning at an average of ~110kw. Given that the Lyric has a smaller battery, it actually charges much faster from 20-52% than the Ford. It will be interesting to see the 0-52% time for the Lyric, which given it's excellent Hwy range, might mean very a very good "1000km (620 mile) challenge" time if the Lyric is charged close to the optimal 52% at each charging stop.

[@BillB33525]

Yes, if the driver does an OoS Kyle Conner 1% arrival and leaves at 50% the results would be pretty good. Unfortunately, most of us will not be duplicating that strategy, my co-pilot wife demands a more comfortable/safe buffer when road tripping.

[@johnsadler6534]

Ok, I am going to ask you. I saw in a video that Ford claimed that the software to control charging was for ICE cars, and they were improving it. My question, do car manufacturers use software to control charging , and when they start to use the NACS connector will it cause a change in software?

[@billjohnson3344]

Hi Tom. Any reply from GM if this is what we are stuck with, or if it is work in progress and will get better? Been on a recent road trip and had the opportunity to charge at a variety of fast charge stations. Common element is that any station that can deliver a respectable peak power (180kW+) and the Lyriq will have that huge drop off after about 15 minutes. Doesn't matter EA, EVgo. Seems a bit worse with higher temps also - definitely looking thermal. Looking forward to your 0-100% video, as well as if you have any comment from GM.

[@newscoulomb3705]

We're starting to see road trip reports from LYRIQ owners, and it's definitely solid. It appears to charge from 10% to 80% in around 30 minutes if the charger is up to the task, so the LYRIQ is definitely faster than Ford's charging profile on the Lighting and Mach-E, similar to Tesla's charging times to 80%, and about 10 to 15 minutes slower than the best-in-class E-GMP and Porsche platforms. I'm not sure whether the issue you encountered was with the specific vehicle or the charger itself (e.g., reduced current due to heat build up), but that "dip" has occasionally been seen by others. It looks like GM still might have some programming left to do to smooth out the 100 kWh Ultium pack's charging profile because it really should be a slow, smooth taper down from 190 kW starting at around 30%.

@@StateOfChargeWithTomMoloughney Yes, the dips have definitely been observed by others, and while it needs to be addressed, there seem to be plenty of examples of ~10% to 80% sessions in 30-35 minutes. So either the dip is happening as a result of leaving the car on and observing (similar to what would happen with the Chevy Bolt EV if the car was left on while monitoring charging speeds) or the dip is happening either way but isn't having a huge impact on overall charging times. Based on your experiences, however, it would appear that the dip is impacting charging times.

Since the first 10 minutes shows 75 added on the DC fast charge why not either drive another 75 miles and plug it in again for another 10 minute charge or unplug it for 5 minutes and plug it in again for another 10 minutes getting 150 miles of charge in 25 minutes.

[@TheAlwards]

I've seen other tests suggesting the drop-off begins between 64 and 75%. I suspect GM's software will give all manner of curves depending on what the sensors are telling it about temperature. As with the Bolt, GM may be prioritizing long battery life through cautious charging: Cut warranty costs by nursing almost all batteries across the line, and minimize disgruntled customers after that by making it likely the battery sees 250K miles. The price? Lower sales to people who insist on the fastest possible turnaround on road trips.

[@douglasengle2704]

I don't have experience with the Lyriq, but for a premium new BEV intended to make life as comfortable as possible the expectation would be to do a 10% to 70% SOC in 15 - 20 minutes with fast DC charging or better. With 350 kWh per hour fast chargers that should be able to totally charge a 75 kWh battery in under 15 minutes if it didn't need to back off on charging rate. BEVs really only make sense right now if they are normally going to be charged over night at home on residential or better electrical rates. Nevertheless it is expected that a company like Cadillac will go to extremes to minimize inconvenience and right now that would be NOT having to wait over a half hour for fast charging. A good minimum wait time to get to is 12 minutes. 12 minutes is the the period that transit agencies have arrived at that people are willing to wait for a bus without bothering to look at schedules and do additional planning. Cadillac owners are likely more picky, but it is likely a a sweet spot where people really notice more time and are somewhat OK to 12 minutes. Of course the goal is fueling times for gasoline vehicles.

[@voldar70]

Not sure why all the fuss over the charging curve. It has a 102+ kWh battery and it added in 40 mins 69 kWh. The charging curve of the Lyric matches the one of the Mach-E with the biggest battery but beats it on efficiency. You say it added in 40 mins enough range to drive 198 miles @ 70 mph. Well, that’s about 10 mins more than the Tesla M3 LR to drive the same 198 miles, charging in the same conditions from 20% to 80%.

[@alanbuck9237]

The only thing I wonder about was whether the charging station had anything to do with the poor performance. Unless you check it on another charger, I don’t think you can really trust the results due to the unreliability of the EA network.

Is it a charger or vehicle issue

[@FoamCrusher]

After GM’s experience with the battery issue of Bolt batteries suffering thermal runaway and burning a few cars to cinders, I suspect that GM is being extremely conservative with its charging curves.

I agree with your assessment. However, my results are much worst. Never had a complete charge (10-80) (dc fat charge) less than 1 hour. No one from GM have an answer at this time .

[@jamesl197999]

Would Like to see 25min or better for 20-80% come on GM.

[@StateOfChargeWithTomMoloughney]

Agreed

[@RangerMan2002]

This does not bode well for the Ultium platform. GM needs to get it together before they release this and it becomes a fiasco.

[@garyclark6747]

Give another GM vehicle charge curves you’ve charted, I think a pass is being too generous at this point. 13:40

[@leonardferguson8413]

SLOW CHARGING THE BATTERY & TO LESS 100% - Increase the life & longevity of your battery compared to frequently rapid charging your battery, it might be a little bit inconvenience with longer charging time but your battery will last a lot longer, I think the same law could apply to your cell phone.👍🏾👍🏾

Since when is 20-80% a full tank of electricity?

[@vlad2838]

At first blush, I would say this doesn’t bode well for Ultium vehicles. Tom, what’s the likelihood this is a product of a deliberately conservative charge curve out the chute by GM? I hope it’s not a reflection of thermal limitations of the pack itself. After all, LG Chem’s fingerprints are all over GM’s batteries.

[@StateOfChargeWithTomMoloughney]

I think there's a very high probability of that

[@realvalue626]

would have liked to see how it compares to other EVs.
