MG ZS EV degradation test after 2 years/25k km

[@bernardhilton3527]

There is a new version of the ZSEV now with a bigger battery. Please test that. Thanks Bjorn, lucky you in that warm climate. In Northern Europe we are beginning to freeze. 👍👍👍

[@snuggles03]

From minus 30C in Norway to 39C in Thailand…I’d be suffering degradation

[@davidofford7002]

Just got to sat 20 seconds in . . . looks great. IT IS great to see you in Thailand, in every way. Best wishes.

[@ryks82]

Thats realy good to know :) i have a MG ZS EV Longrange 2022 on the way :) an consider the battery size and how much easyer that is to ceep in right battery range it problebly takes much longer before you can se any degradation :)

[@jacquelinebrunder2384]

Battery degradation is negligible where a decent battery temperature control system is fitted. The reason the Leaf battery degradation is around 3% per year on the older cars is simply because they have no battery temperature controls.

[@paulaschofield]

Good to see that the MG is holding it battery. We have a 2017 Ioniq 28kWh and have just passed 100,000km and it's now 5 and a half years old, and according to EVNotify and also the range we are getting when full, we don't have any degradation of the usable battery. Looking at the information in EVNotify it also looks as though we have only used half of the hidden 10% of the battery, so we could assume, if the degradation doens't speed up, that we could get another 100,000km and 5 and a half years of driving before the degradation starts to impact the range.

[@DanBoro]

Will you be doing an update/range test on the new MG ZS EV Long Range ?

[@bjornnyland]

Yes

[@and1111000]

Hi Bjorn, take us to the lovely Thai beaches please.

[@hellopsp180]

Pretty decent. It’s definitely the TOP buffer you said. If MG had software read out of SOH of battery it would be a quicker way to find out degradation tbh. Start at like 110% SOH so you get extra 10% buffer

[@robenglish416]

Thanks for the test, will look in to the MG brand when current lease goes out!

[@Colin623]

Degradation will happen over time for sure, but then again so does a petrol engine, so no big deal to be honest !

[@jpdj2715]

(Introduction) In solid state memory (like SSD and flash memory cards), each memory cell rewrite is a bit of brown-out - plainly called "wear", elegantly called "degradation". The extent to which this happens is highly determinant of price (next to mainly speed and available to the user capacity). Manufacturers publish memory life time in "TBW" as this indicates how many times a cell can be rewritten and the firmware in the cards does a "wear leveling" process. How do we get cards that last longer? (A) with better and much more expensive memory cells or (B) through "over provisioning". In over provisioning, you may have 50% more capacity than visible to you and it is used in the wear leveling process. This could be done with cheap memory cell tech to get better TBW or with expensive cell tech to get enterprise or data center class SSD. (Question) Is it possible that the battery bank in the ZS EV is configured/sold with a level of over-provisioning of battery cells that are used in a wear leveling process? As the battery is the most expensive part of the car (assumption) this would be reflected in the price somehow, but as the car is a complex package that would be hard to identify.

Possible, but I find it very unlikely...

[@CampGareth]

Wear levelling doesn't really apply to a battery pack, individual cells don't see differing loads and the wiring to be able to swap a cell for any other cell would be really complex. In SSD terms imagine the only way to use a drive is to write to every cell simultaneously. All cells see the same load. Some are weaker than others and will fail earlier, but we only have e.g. 10 of them and we need to expose all that capacity to the user. Some cars will overprovision so you have 12 cells of capacity but only expose 10 to the user, even then all 12 cells are in use and each cell sees 10/12 of a full load cycle extending its life, especially as that final little bit really damages the cell.

My MG EV shows 96.9% state of health on obd after 1 year and 17K km in New Zealand. Average temperatures similar to Europe .Still better than the 2 Nissan leafs previously owned .

EQS now available in Thailand. Booth at central world bkk.

[@navinchandran6513]

A very informative video and would be awesome to see a range test on Model 3 LFP cars after 25k km. I had an MG and sold it at 10k kms and the range was still intact at 262kms after driving for that period which indicates there is a hidden buffer. Now I have switched to Tesla and find the battery efficiency on Tesla is unmatched. I am getting 11.6kwh/100 kms and in MG the best ever was 14kwh. I am from NZ and it's currently summer here. Look forward to seeing more great content from Thailand.

[@kbhasi]

(1:02) I won't be surprised if that screen is also present on the version sold in Singapore.

[@thereal4nd]

Will you be doing any reviews while in Thailand, I believe the ORA Cat is available there, a car coming to uk/Europe early in the new year.

[@DG-uv3zw]

He will try to get cars to test. Possibly, yes!

[@FSXgta]

Watch the previous video

[@jhchooo]

Doesn't this car have LFP battery? LFP's degrade slower in the beginning than Nickel based LIthium cells

[@bjornnyland]

NMC from CATL

[@altern8ive]

I wonder how quick degradation becomes apparent with minimal (or zero) fast charging?

[@Aron_Dettingen_Erms]

Will you also test the MG Marvel R then you are back in Norway?

[@theproffessional9]

I'd guess that it's more of a top buffer being eaten away if it charges slower towards the end, but if it charges the same it's most likely a bottom buffer.

[@bjornnyland]

Or we could look at voltage.

[@hyy3657]

i think yeah, Asian car brand has some different philosophy

[@thorbjrnhellehaven5766]

@@bjornnyland yes, looking at voltage and the other values is good. Then compare if the corresponding % and kWh change with voltage. Love your videos! If people ask anything related to trip planning I reply APRP. If they ask about car specifics I reply Teslabjørn. :-) I used to watch all your videos back when you had a job on the side, before going full time KZbin. I used to drive eGolf, was mostly happy with it, but missing trailer hitch. I watched all videos hoping they would get a hitch. I had first day reservation on eNiro (less than No.100 in cue). After I got Model3 SR+ in 2019 I still love to watch your videos, but no not all of them, because I am not researching a new car, just love good videos about EVs.

[@EVAddicted]

Hay I have same car done 28k battery degradation so far is 14km in 22 months. I love your dedication on Ev’s. 🇮🇳 👍👌👏🏼

[@kiranrepana784]

I own 2020 version, it showed a degradation of 22 km in 18months, odo is 28k km. Have you checked with the service center for excess degradation?

[@sie4431]

I hope we will get to see that leaf from last time again and perhaps some lesfspy analysis

[@Blind-Dave]

Good to see you driving on the right (correct) side of the car 😎

[@itsfahys]

I Like the under ground hotel car park chargers. Would be interested to know if youve seen much of an improvement in the charging Network since you where in Thailand last and what new EV models are available. I recall watching videos from your last trip and you showed that Imported EVs had a very high tax on them, so has this changed at all? Thank you and look forward to next video.

[@Robis-]

You h`ve hollydays or relocated from norway?

[@targus200]

Does colder vs warmer climate affect degradation? MG ZS EV Thailand vs Norway.

[@steilkurbler4973]

What I learned from LiPo cells in RC planes is that they like to be stored in colder enviroment, but like to be used at around 15-20°C. Storing them colder supposedly slows the degradation that happens over time(the one which happens without use). But I am not sure, if it transfers over to EVs batteries, because they are Li-Ion, so a bit different chemistry. I'd say something with Climate like Germany or even UK would be best for battery thermals. Not too hot, not too cold. But I am no expert after all.

[@hirnlegorush]

yesterday after seeing your vid i walked by a Mercedes dealer here in Germany and saw adverstising put on the fence for MG electric -not sure but it seems you can buy them there ?

[@bhmbill]

Does the MG get over the air updates?

[@kennethjessop6073]

I just watched Red Notice on Netflix. Dwayne Johnson wrecks a Taycan in the worlds shortest car chase.😹

[@sacharanc]

The MG doesn’t have LFP batteries and much less degradation then?

[@bjornnyland]

NMC

[@sacharanc]

@@bjornnyland thank you. I didn’t know. So from now it’s LFP?

[@AnoopSinghRanhotra]

What is the reason for you to divide by 0.98 and 0.96 instead of just 1kw =1000watts

[@bjornnyland]

That's the % of the battery I spent. It has nothing to do with kW to W conversion.

[@AnoopSinghRanhotra]

@@bjornnyland oh, so 2% remaining in one run, and 4% remaining in new test. 👌 🆗 Greetings from Nepal 🇳🇵

[@davidwatson22]

Good to have some reviews of cars that us common people can afford , so what's it like to be a left lane hugger after driving all those miles on the wrong side of the road 🤣🤣 hope you do review that Chinese ora cat can not see it overheating in Europe

[@dgurevich1]

Got mine 6 months ago, 17500km. I only fast charged it 3 times so far. I keep the battery between 80% and 20% most of the time. I only charge it to 100% when going on a road trip. Temperature ranges between 10c in winter and 35c most of the year. I wonder if there is actual battery state of health report from OBD2 or not.

[@Porkonfork]

Seeing the same in Aus, State of Charge 94% (unchanged since new) and State of Health down from 100% to 97.1% after 23k km. I think MG are hiding the degradation in the 6% (2.64 KwH) fenced off in the battery pack.

[@williamarmstrong7199]

My MG5 is still doing the same milage as when new. Yet my service report shows battery SOH 87% @ 40,000. Could I have lost 13% of the buffer already? If so then the battery will be toast long before 100k miles.

I would sincerely hope for a car not to have range degradation after 25K km....It's a bit worrying for such question to arise for us all which are supposed to embrace EVs in a near future.

Degradation happens after two years regardless.
