These OBD2 with apps are not an accurate test of battery degradation and only read the cars software which is completely inaccurate

Regular rapid charging never recommended due to potential pack damage. Properly temperature managed packs do better. Warranty work is to take normal degradation back to 80% of original available (without original buffer) replacing cells as required rather than all new pack. Buffer allows excess capacity to be released by service department to maintain "available" to user kWh until 8 year warranty expiry. Thereafter degradation has direct impact on "available" capacity - what most see as 100% SoC. But that might be 150km to 8 year point or some time later 80km after warranty expires. VW eGolf & Leaf mk1-2 have worse issues than MINI E which has similar pack to BMW i3. VW ID3 now suffering higher deg than expected: kzbin.info/www/bejne/o5OkY6eEdrxropo

That was interesting, thanks. It would be nice if you could upgrade the battery when better one come out. The distance is supposed to improve in the next few years.

Reading the SoH value from the BMS is not a reliable measure in any way shape or form. It is actually quite complicated to actually measure degradation.

Ours is coming up 3 years old, done 17,500 miles (28,000 km), we've had it 15 months (and 7,000mls/10,500kms), average over last year has been 4.4 miles per kwh and roughly 1.3 to 1.4 miles per battery% (i.e. 100% = 130-140 miles), only charged at home on 7kw smart charger to 80% though. Had one new tyre due to a cut, other 3 are around 50% worn. Seen examples with over 75,000 miles/120,000 kms on the clock.

I enjoyed your video. I retired from auto repair business before I had a chance to service anything but hybrids. I could use an EV for commute to town. Just not sure my budget would allow it. Still driving 99 Accord I bought new. Actually the most trouble free car I’ve ever owned. I just visited Dusenberg museum in far northern Indiana. Interesting newspaper article from 1909 newspaper that said EV and ICE vehicles could co exist just fine. I really wish I could understand the huge divide we have now though I suspect it has to do with MONEY. Then I realized the Dusenberg was 25-35 times the price of a Model T. So I guess it was a lot about class warfare then and today.

I just recently also bought a Mini Cooper SE, although a used first gen one (2020 model) with around 19.000 kilometers. I also checked the battery SoH prior using an app called "electrified" which is free but only works with the BMW i3 - however the Mini SE and i3 are so similar, the app has zero issues connecting to the Cooper. Long story short, the car's battery SoH is shown at 97,5%. However just as other people mentioned, my dealer also told me these software readings should be taken with a grain of salt, they aren't really accurate and it is quite complicated to really measure the actual degredation.

@alanhowemusic2457 9 ай бұрын

Problem with battery health longevity is if the cooling system that controls the temperature of the battery isn’t working properly or is not checked during a service this will cause battery degradation more rapidly.

@simplygregsterev 9 ай бұрын

Chevy Bolts will toss a code for low coolant that will prevent rapid charging unless the bcm is reset

Interesting‼️. If you want detailed information you should watch videos by “Weber State” Automotive school. He has disassembled several EV battery packs.

I’m curious. Why did you say “unfortunately” it uses OBD2 data link connector. That standard has changed automobile diagnostic capabilities more than anything in my 50 yr career in car service. That’s just my opinion. Was curious about your thoughts.

@simplygregsterev 9 ай бұрын

Obd2 is outdated on EVs. Its there for emission reasons on ICE but gets hung over from being a standard. Model 3 and Model Y dont use OBD2 port here. They use a hybrid CAT6 connector.. you can use obd2 port but need to get a splice harness near the centre console. I just find it a bit silly the industry is still using such an old style coms system

@dharley189 9 ай бұрын

In ICE cars OBD1 was strictly emissions data. OBD2 allows communication with so many more systems not related to the engine at all. I E climate control, body functions, air bags, instrumentation and so on. Not sure where your level of expertise with ICE and electronics is at. But it seems that it would force techs to purchase new scan tools (not code readers) to access all the computer modules in an EV. OBD2 DLC was brought out to correct the problem of having a different DLC for every manufacturer. Oh well. I guess history kind of repeats itself. Do you know if all EVs have the OBD2 DLC and just Tesla has the CAT6 DLC ? It’s been interesting learning some technical stuff. Time will tell if they will be adopted by the middle class and lower income folks.

So many ICE brands require special scan tools. BMW and MB are two off the top of my head. OBD2 is overly generic for modern car computers.

@dharley189 9 ай бұрын

⁠⁠@@coprolite_steve. No it’s the software that makes the difference. By law 1996 and up use same DLC. used to have over 20 cables with different ends. Usually no one gives out security/immobilizer information. That’s where a factory scan tool is required, but it uses the same DLC as a lowly Dodge Neon 😕. Also different scan tool manufacturers won’t spend the money to make all the modules communicate but that is not that common. It all revolves around MONEY.. Been at it 50 yrs. Some things just don’t change. But you could be right. I’ve been retired from that rat race 8 yrs. Hope you have a great week ‼️

@@dharley189 I always used a scan tool on my BMW but the codes that came out were generic so it was like reading hieroglyphics. I wasn’t about to buy an OEM one for occasional work. Flushing the Transmission properly also required the BMW tool to read all the related temperatures. Of course, they called the fluid “lifetime” fluid so you know that headache given your background. My friend who basically rebuilt his E class wouldn’t have been able to keep his cars up without the MB computer for the advanced work. I am not knocking OBD2, it is great. However, it is no longer up to snuff with these computers on wheels these days. Missing my old ‘66 vette more and more every day.

What is the point of being afraid to fully refuel a vehicle. I don't have that fear with my petrol car and my fuel tank doesn't degrade in its capacity. Battery degradation is just another reason to avoid EVs. I only fill my car when I need to and I don't limit the range ever by not letting it get below 20% or above 80%. It just shows the stupidity of this poor EV technology. My petrol car has covered 110,000km and gives better economy than when it was new and looks like continuing to do so for another 100,000kms at least. My last petrol car was still amazingly economical with well over 200,000kms on the clock.

Yes, and you have polluted quite a bit, and probably don't care about your CO2 emissions. But there are many of us who do NOT feel that way - and drive with a very happy EV, and will NEVER go back to an ice car...

@JunkerOnDrums 9 ай бұрын

@albinvega7008 Nonsense - EV's don't consume tires at that rate! I know because i have driven EV for several years! And problems can with microparticles obviously require a solution. But pollution from ICE cars can be solved with EVs!

@JunkerOnDrums 9 ай бұрын

@albinvega7008 Nonsense!: Ah, the battery. Big oil is trying very hard to convince you with their campaign, but the battery in current EVs should be good for 15 years or more, based on a lot of numbers from Tesla et al. I’ll have saved for mine inside of five years - $20K Canadian plus $2-300 to exchange it. Compare that to replacing the motor and transmission in your Mazda. Which sure, is a very good car. Every litre of gas you put in it starts at prospecting for oil, drilling, shipping the crude, refining it, and distributing it to the gas station. But that isn’t figured in the carbon cost of running an ICE car, just tailpipe emissions. A lot is made about the dirty secrets in making batteries. But big oil doesn’t want you to know about theirs.

what? BMS'es have proven extremely reliable, why would that now be an issue? Also in every modern ICE, all vital components are controlled by a microprocessor.
