What is GM Hiding with the Chevy Equinox EV Battery Capacity? 2RS AWD Put to the test with OBD2!

[@scottoakley6862]

I picked up my 3RS eAWD last week, they had charged it to 100%, and the display showed 577km of range or 358miles, crazy mileage and will have to see where it settles in the weeks/months to come. Nice video thanks for all the info.

[@Eventurefamily]

That’s interesting. I wonder if it wasn’t at all configured or possibly had a very low amount of miles with a very high efficiency before delivery. I believe it just calculates the range based on kWh remaining times the recent consumption. Mine currently shows 303 which is excellent for the AWD also. I’d be very happy if I actually got that.

[@scottoakley6862]

@@Eventurefamily You are probably right, it just completed the Pdi with under 100kms, likely only the second time it’s been charged to 100%, assuming they do it at the factory for battery stabilization. But so far averaging 4.8kw/h. Cheers

[@mattblanchette2767]

Mine has only gone up since delivery. 2 weeks, 700 miles or so. Full charge from the dealer with 17 miles was showing me around EPA estimate. After 2 weeks, the car is showing me around 360 on a full charge. Not sure if it’s my commute or it’s very efficient but it’s running incredibly efficiently.

Great video. I just got a 2024 3LT, FWD Equinox. Traded in a 2023 Bolt EUV. So far very impressed with the Equinox. A 90 kWh pack would certainly be an additional plus.

[@Eventurefamily]

Congrats! I was so surprised with how great it is. I didn’t have the best impression of Chevy but this has really opened my eyes. I’m loving it so far too.

[@8bajwa8]

Just curious what did they offer for bolt.

[@ianvankirk8820]

I took mine on an out of town overnight trip to the Adirondacks (I live in Vermont) the day after I got it. I got home with 224 miles on the trip and 110 estimated range remaining. I’m not great at math but that seems to be more than 319 to me. So far so good.

[@SJVH1]

Interesting video as always. Great detective work. Much appreciated!

[@Eventurefamily]

Thanks a ton! It was a good amount of work but worth it as I learned a ton. I’m glad you appreciate it and enjoyed it as well!

[@dianewallace6064]

Sasquatch on your ball cap. Yes, I think Tom got 303 miles of range so this backs up your calculations. I didn't think about the warranty but that's a good point or internal buffer like you said. I'd rather manufacturers under promise and over deliver though. Thanks for this data. Very interesting.

[@Eventurefamily]

The hat was a great pick up from a cool local store in CO that sells locally made items. Very happy with it. I agree. This would be worse if the range or capacity were less than what GM promised. It seems like we’re getting some additional battery over what we were told which is awesome.

[@dianewallace6064]

@Eventurefamily It is great to have a 100kwh battery instead of 85kwh. I like the ball cap. I like to buy funny T shirts and ball caps.

Your video topic was a very interesting choice. The facts presented about the GM Ultuim product line is a bit off. Your demonstration of the battery pack voltage is not typical for everyday results. Battery chemistry environment is critical to the reading at any point in time and does vary widely based upon that environment for that moment in time you take the reading. I am a Lyriq and a Silverado EV RST owner. I did not plan to purchase 2 GM products this year, we just ended up going that way, I have no loyalty to GM. The GM Ultuim product line is to have 6, 8, 10, 12, 14, 20 and 24 module battery pack options for its vehicles. The Equinox uses the 10 module battery pack wired as 3p80s configuration with a nominal ~330V operation. The Lyriq uses a 12 module battery pack wired as 3p96s configuration with a slightly under nominal ~400V operation. The lyriq can ask for a higher charging voltage at a rated 150KW charger and not max out the charger’s 350 amp limitation and achieve a near 150KW charging speed. The Equinox will need to use a 350KW charger because of its lower voltage asking rate at a 350KW charger and receive near 500 amps to achieve the same 150KW charging speed. (350KW chargers have a much higher amperage capacity) The lower pack voltage is the way GM is being conservative with its overall battery life span planning. The Ultuim battery packs are more durable over the long run than most of its competitors because the voltage ratings they use have less stress on the battery.

[@Eventurefamily]

Thanks so much for this additional information. I did look around to find the nominal voltage and what I found said it was 3.6v per module, but I couldn’t find a true confirmation of it anywhere. Do you know if GM plans to actually make any vehicles with the 6 or 8 module configuration? It seems like the voltage with 6 especially would be so low that charging would be really slow unless the amperage was incredibly high (and wasteful).

[@kelviskelvis7140]

@@Eventurefamily Nothing recent from GM. Specialty fleet use vehicles may be where the 6 or 8 module batteries show up. Maybe the hybrid vehicles would be the application. The listing of battery packs came from 2020 Ultium literature so it could be out of date by now. GM is pretty tight lipped on their product roll out plans.

[@vincentplan3473]

I'm actually surprised myself when i got mine. Better than advertised. Lol

[@Eventurefamily]

Absolutely! I didn't have the highest impression or hopes for Chevy, especially with higher tech EVs, but they really did a great job with this one.

[@EnjoyingmyEV]

Are you able to retrieve battery pack temperatures with the Top Don. If so the next time you do a DC charge could please see what kind of temps you are seeing in relation to the power level and post a video on that.

[@barryhomes1]

This is a really good video. And I like the deep dive you are doing. :-) And I don’t believe the different vehicles are a different voltage. I believe the motors operate at about 400-ish volts. That some of the packs are wired in series to get the 400-Ish voltage. voltage.And that as the add more packs, they have more current, which gives them more torque and power available. All of the skateboard electric motors I believe are the same design. (These new motors that GM is using, are kind of like the small block Chevy motor). It’s a very versatile design. This also allows for rapid charging in larger vehicles. In the larger Silverado EV, my suspicions are, there are two (120 kW-ish) packs wired in parallel. This would allow to charge at twice the rate. It’s really not that difficult (you’re kind of charging two packs at once, no extra stress on the battery) Barry :-)

[@Eventurefamily]

Thanks a ton! I'm by no means an expert on this, other than my one electronics engineering course in college (too long ago), but I'm trying to learn. I am 99% sure you're right about the Silverado (and Hummer EV) as we know that they have a physical connect/disconnect that connects the packs in parallel when it is plugged into a high voltage charger. Thanks for the additional context and for watching!

[@iannation8796]

I'm super confused. Mine started at 301 now it's down to 285.

[@Eventurefamily]

Have you done more high speed or highway driving since then? Maybe there’s also some sort of calibration period when new. Mine still shows over 300 at 100% but we’re still only at about 200miles now.

[@SciD1]

Thank you for this video. I learned a few things. Why is the Equinox EV battery operating at lower voltage? GM has to have a reason. What would be the advantage of having such a low voltage?

[@RyanTobler]

Cheap

[@kelviskelvis7140]

@@RyanTobler Incorrect, better life span.

[@Eventurefamily]

Lifespan might be one factor as it would be a lower voltage through the battery during both discharge (driving) and charging. However, I believe the main reason is that it allows them to scale Ultium configurations up by simply adding more modules (or fewer) in series to go from the 10 module config here in the Equinox EV all the way up to the nearly 800v in the big 24 module vehicles like the Hummer and Sierra.

Awesome video. I learned a lot. Thx for sharing all this. Thx for the video. I enjoyed watching

[@Eventurefamily]

Glad it was helpful! Thanks for watching!

[@marissakphotography6604]

Picking up my EQ EV RS 2wd today. Which obd App are you using with the topdon scanner? Been using OBD fusion with my Bolt, with custom pids. Wouldn’t mind seeing battery into on the EQ either….

[@Eventurefamily]

I was only able to get the TopGuru scanner app to work. I tried car scanner and another one I forget now but wasn’t able to get those to show the data. It would be nice to see more charging info and battery on the menus in the screen for sure!

[@EV_OBD]

Car Scanner ELM OBD2 also works in Equinox EV (connection profile Chevrolet Ultium EV).

[@roamingbeemer]

Do they leave a buffer for longevity?

[@Eventurefamily]

Yes, very likely. Unfortunately there is no official information on that so we have to guess

[@lyonloomis980]

Rambling nonsense which could have been condensed into less than a minute. GM may have made a conservative estimate of it's battery size. WooHoo.
