How's My Electric Car Battery After 100,000 Miles?
HTML-код
- Опубликовано: 1 окт 2024
- This week we are following on with another update on our MG5 EV. It's now covered 100,500 miles and is 2 years old. We take you around the vehicle to show wear and tear, show how the traction battery is holding up in very heavy use and we look at the wear on the brakes.

In my job we have a BYD eT3 with 470k km.
Its perfect till now, zero fix maintenance
So much for many of the anti-EV crowd, who say the battery has to be renewed after 6 or 7 years. Right here, we have the equivalent of 14 years average motoring... And as for the silly scare stories regarding brakes........ Thanks for the video James.
Great review James. This is a great real world ‘worst case scenario’ example based on the vehicle daily use. This is the kind of stuff the media need to use.
Well done and keep up the great work.
I’ve put a post up on my EV channel to promote your video 🙌✊
Thank you 🙏🏼
@@Jamesandkate quick question if you don’t mind. Where do you send the diagnostic data from the BMS to to get your degradation report? Would love to do one on my MG4 which is 1 year old. Thanks
Of course ignoring the cobolt and lithium slave conditions !
I take it you don't use Petrol or Diesel then? Cobalt is used to remove sulphur from fossil fuels and it is then spat out of the exhaust for us all to breath btw cobalt in the atmosphere is a lung irritant LFP batteries don't contain any cobalt and lithium is obtained from Australia/South America and not Africa. A recent lithium discovery in /north America might mean the US becomes the largest lithium producer in the world if they decide to mine it. @@gowdsake7103

I think that I watced one of your early videos on the MG5 and that convinced me to purchase one - I'd never owned a brand new car ever before in my life - I'm now 80. For many years I'd run Landrovers, Discoverys and also three Range Rovers. In fact my last ICE car was a 2004 L322 Range Rover which had an LPG conversion - that was the only way I could afford to run it!! I've had the MG5 since October 2001 and I've no regrets whatsoever. My wife and I just love the vehicle; it does everything that we want, is comfortable, easy to drive and cheap to run - what more could you want. Thanks for the video.
Thanks for your amazing comment and I'm glad the MG is looking after you both 👍🏼
since 2001?
James, how did the oil change look? Any engine fibres in the oil as it slowly destroys itself!? Oh wait… 😅 Thank you for your honest approach 👍🏻 My old diesel went to scrap last week and my new MG4 has done 400 miles in 5 days. 🎉
Amazing. We serviced an MG4 a few days ago and when test driving it reminded me how good they are to drive, such a great car.
smart meters digital money evs all part of the WEF 20-30 agenda and its all about control.remember how your battery was made and what effect on the environment.iys only zero emmisions while being used.ruclips.net/video/HASkPCkMhbgh/видео.htmlttps://ruclips.net/video/yOA7qKMcjcE/видео.html
No oil? Well wait till the bearings in the motor burn out, see if its cheaper than replacing a diesel engine.
Let me put you out of your misery, no its not. But keep driving those monstrosities. BTW, did you know the battery associated EMF damage the brain? But on the bright side, EV evangelists will be immune to further brain damage, they already have problems in that department.
Good stuff. Watched Petrol Peds interview with his pal Moggy who electrifies classic vehicles and they did some decent myth busting as well. The phrase that stuck in my mind was when listening to somebody always value experience over opinion and this video shows how durable the modern EV is. Top work.
If you had a diesel averaging 50 MPG (imperial), that would cost £15,000 for 100,000 miles at current average diesel prices (£1.58/l). Charging at night on Octopus Go and averaging 4 miles/kWh, it would cost less than £2000, which is similar to the servicing costs for diesel. So if the car cost £30K and goes for 200K miles, it's fully paid for itself in fuel and servicing savings (the same total cost as a free diesel car)!
I don't think the none EV owners quite believe how cheap it is to run an EV, my sister looked at an electric van and was quoted £600 more for insurance than a diesel van so she dismissed it. Not including all costs and doing total cost of ownership will get you the wrong answer.. For myself I have now got my house electric/car fuel bill down to about £30 per month to run a 6 bedroom house with 6 people living in it and driving 8500 miles per year in an i3, Solar, House battery , EV, Octoppus Intelligent means I get 8.5Mwh per year for £50/month and I get £200 ish FIT/year. Next year I start getting my Ripple Energy credit so I will probably be in credit each month! 7 years of planning and saving for this is now paying back in spades. Next job heat pump..
That's impressive, good work. Sadly, some people can't think outside the box 🙁
@Jamesandkate Correct, but it's ingenious how they have managed to nail the box shut from the inside.😅
While that end result sounds cheap, how much investment has that taken and how long to break even? It's not that a lot of ICE owners don't know how cheap it 'can' be, they don't have that sort of money to make it work. It's like saying to someone they can live really cheaply only they would spend £50k first (off the top of my head).
It wasn't cheap but over 7 years it was ok. I bought second hand EVs over that time and the payback was much shorter as the price of energy rocketed. I am expecting about 8 years payback. Things to consider: do you have savings and how much interest are you getting? I chose to use my savings to remove all future electricty and diesel bills. Inflation will happen to your bills but it cannot effect an asset. @@noggintube
@@noggintubewell said mate, let's spend 20 grand on solar panels that MIGHT pay for themselves just as they are end of life. There is no way, zero, that ev car/solar or battery walls etc is substantially cheaper when factor in everything like upfront cost/difference, depreciation, etc etc. we haven't even got to the stage when ev will be charged extra to charge at home, if people think the government isn't going to come after duty then they are simply delusional.
Those of us who took a bit of a punt ordering the ZS Mk1 before they were available to drive have been rewarded with a great car. If the battery holds up as well as yours on the MG5 I will be thrilled. Having said that I might look to change in the next 12 months for a slightly longer range and faster rapid charging. But then we did a 300 mile trip we lost only 20 minutes compared to an ICE. Thanks for the update and keep up the good work to help persuade others!
20 mins to do a full charge at how much??? 😂😂And you found a charger that actually worked????😂😂😂
@@originalshadowfax That isn't what I said. We charged for a total of 50 minutes or so but weren't delayed mostly because of using other facilities. The car does 3.7 miles to a kWh roughly though on that morning my wife drove because I was unwell, I spotted her doing 85 mph which is not the way to conserve battery. Starting out with ~150 miles of range the charging cost about £24, we arrived home with the charge me now light flashing, that is success in my book.
No issue with chargers not working, plenty of them on that route but dozens more now 12 months on. Charging prices have come down since last year and with more and more competition we should see further falls. Of course I don't have the servicing bills that you have with a diesel, no oil to change, no fuel filter, no cam belt (just did that on a Passat ouch!), no brakes to replace discs or pads, and it has got truly big diameter discs on the front. And so easy and quiet to drive. So much so that friends don't believe you are in a car when you have a phone conversation. And one of the benefits of having an EV is the cheap electricity. I pay 7.5p a kWh for 6 hours a night which is for charging the car, but also I run a heat pump only at night for 7/8 months of the year. My 10,000 kWh consumption is 65/35 night to day tariff which altogether costs about half of the cost of diesel, electricity and oil for CH that I was previously paying.@@originalshadowfax
😢 Money always makes money! I too have invested in renewables, solar, EV, heatpump and it was a large investment however I’m getting a return on that investment that beats what the bank was paying. As for payback I’ve increased the value of my home and made it a better buy compared to my neighbours that hasn’t all this technology. However it’s those with the money to invest that benefit most.
This isn't just 100,000 miles like a normal person might run for several years - this is hard commercial running (50k miles a year!). So really good breakdown to show how practical commercial use EVs can be (granted vans etc are a little new still but there are some good ones now I think?)
Impressive Quality. Well done SAIC/MG.
Thanks James. I look forward to hearing your review of the car after 200,000 miles. Those brake calipers will still be good for another 100,000. 🙂👍
When I drove the MG5 I found it disappointing only because I'd previously driven a Kia e-Niro. Headroom, rear window view, instinctive control locations all scored lower for me. But you can't argue with the longevity and solid performance over time. A solid car. Yet another EV review with actual facts that puts the lie to the usual nonsense circulating in the mainstream media and among internet trolls.
They're 100% not for everyone. Tbh, the eNiro is a very nice car, one we considered ourselves 👍🏼
Just got my mg5 today, have to return my niro now. I feel the same i am dissapointed with the mg5, mostly because of the range I saw. 170 mile range, I know it is winter but a 80 mile lost!
@@miyoy21efficiency also depends on how you drive...
@@miyoy21 I have an MG5 and the range has been pretty much spot on. If it was 100% and showing 170miles I suspect it was based on the delivery mileage and dealer driving it. Hopefully now it is showing nearer to true mileage. (also make sure it is in ECO mode and the heater turned off)
Great to see this James, an honest rebuttal of the FUD generated. Great to see the MG holding up as well as any make! My ZS Mk1 is still great after nearly 4 years, thanks for the intro at your favourite car park film location...🤣🤣 Still using independent EV servicing (when I do) , hate the BS from most Main Stealers.
Amazing to hear. We keep it as honest as we can 👍🏼
My MG5 is due it's first service soon so you not lose the warranty if you go independent which I would much prefer . As you say too much BS from dealer
actually I love the FUD, making the ev used car price plummet so much more than ice car so I can get very very good deal
James, Thanks for this close up view of how well your MG EVs have been holding up with heavy use. On the subject of wear that occurs with calendar aging, vs miles, the biggest concern IMO is corrosion. This can lead to an expensive battery replacement when corrosion results in water intrusion into an EV battery pack. Owners of early Model S have had battery failures caused by corrosion of the fuse cover or vents allowing water to enter the pack. Tesla improved their battery design to be more robust to corrosion in later years (2015-ish and later).
There are ways to slow down corrosion. Rustcheck is something should be done regularly on high corrosivse climate. I did on my civic. I got it used 14 years ago when it was already 5 years old. After 19 years on the road. Only the roof was rusted though. ( that was from due to design flaw from honda.
Good review thanks. My dad has a 2 year old MG5 52kwh 32k miles. 2 minor issues 1 just a software update 2nd rear screen washer pipe came lose inside door pillar and one bigger problem when car wouldn't charge 200 miles from home. After 4 weeks in MG garage and a whole new charger socket. Still unable to charge they discovered a big fuse under the charge socket! Hey presto. Apparently he is the first person to have this issue. He still loves it though!
just ordered a MG4 long range luxury spec(4weeks delivery time) , thx for clearing the battery degradation thing , that was what i worried most about when buying the MG .keep up the good video's
Enjoy it, they drive better than almost all other EVs imo.
I have the MG4 Trophy 64kWh. Happy to answer any questions you may have my friend.
Brilliant vlog. I still have the leaf and still looking lol. Best wishes
I'm changing my 150Ah battery modules for 174Ah (52 - 61kWh) if they made 200Ah modules in the same form, it would give it 70kWh and around 300miles range driving carefully! Tesla beater?
I don’t have a home charger yet. I live in a small block’s bungalow and have a private parking space in a communal parking lot.
Hopefully you can get one, it makes running an EV so so cheap.
100,000 mikes in 2 years?
Wow
960 miles (1500km) per week average
307km/day
Heck. Pretty much an ideal justification for an ev.
Still has the disadvantages over a diesel. Range leading to Range anxiety. Constant planning of routes due to lack of chargers, initial cost, and charging times especially if you can’t charge from home. Possible future power supply problems if sales outpace chargers availability and the necessary nuclear power stations that take 15 years plus to build. For 33 million cars going electric and applying average milage ( 10000 ), average range (250 miles ), average battery pack ( 54 kW ) works out at an additional annual power requirement of 89gWs of power and that’s over the output of 2 of the largest nuclear power stations ever built each rated at 39gWs output annually. Now consider van,trucks and lorries heat pumps, cooking all to be electric then there will need to be even more nuclear power stations built. Another problem is EVs are not very suitable for towing caravans or charging when having a caravan hooked on. ( see Pedro Pete RUclips re towing a caravan. ). Motor homes will have a restrictive range and an overall gross weight ( Citroen relay has either 73 mile or 137 mile range depending on battery choice. ) The trouble EVs have their place but they are not suitable for every thing.
Modern car seats are designed to pander to the fantasies of middle aged sales guys from the mid 2000's 🤦♂️ "support" for "sports" driving in Ur diesel Mondeo and means most seats are now narrower than people with side bolsters that transfer all the violent lateral impacts from driving on crappy potholed uneven UK roads straight into your spine. It's incredibly stupid design that won't be solved until dudes running fleet purchasing are replaced by ....well, until fleets aren't a thing anymore. Vans are still ok, so are some bottom end cars but yeah, anything that's bought by reps is terminally uncomfortable but hey, things working right hasn't been a priority in the UK for years and we don't care as long as we get a GT badge or "Sport" on the back of our SUV crossovers 🤷♂️
Hi James ,John from Ayrshire Scotland great review up to 24000 in my 22 reg MG5 going to work and home great car. Thanks for the great update on how your cars are going and keep them coming as they are of great interest to me.
I have the facelift version in black, on the whole its a decent car however the paint is extremely soft. It had a full machine polish, the paint was swirl and scratch free, two very careful washes later by me using snow foams, best shampoo, wool mits and just being very careful, the paint looks terrible again. Would certainly avoid a black one.
Shows the dirt too
Hi James - Thanks for the informed video.
The MG5's have proven to be a great workhorse and brilliant purchase.
Very interesting to see your very limit brake pad wear.
Some lower milage owners of both MG5's and ZS EV's are seeing dealers requesting discs & pads replacement at only two years old !.
Rear disc's on the ZS EV are only available as OEM items and are expensive.
Have you witnessed any premature replacement necessary yourself ?.
Are you using the OEM disc's on the rear's ?.
Thanks.
Hi, this is normally through corrosion and lack of use, but lack of servicing the rear pads that seize also cause problems. We can source aftermarket rear discs and pads and have changed a few on the ZS to date.
Thank you James - I will pass on your comments, I have had no luck tracking down third party rear discs for the ZS EV@@Jamesandkate
Worth stating on your fleet. They aren't cosseted. They're aren't your pride and joy like someone's private car. They're a tool to let you do your job.
Only had the one issue on ours. The 12V battery went flat through lack of use and wouldn't take a charge. At the time, my wife (it's her car) was WFH full time so it only went to the shops. A new 12V battery was fitted and now she works a good distance from home and goes in 2 days a week. Otherwise zero issues. It's a great car.
thats pretty damn good, so much for the ‘cheap’ in chinese
Indeed 👍🏼
I second the opinion of the car.
Almost 60k miles done and the only issue I've experienced is the little rattling noise from the dash on very low speeds... Other than that, no issues...
Front tyres replaced after 35k miles (for more grippy ones as the factory fitted ones were rubbish).
Rear ones replaced after 50k miles.
Regarding the warranty on these, because of the fact that I cover over 30k miles a year I chose 12month unconditional warranty from TyrePros (£12 each). They replace and fix tyres during the whole period of warranty regardless of the tyre usage. Highly recommended!
As for the electricity usage, on average I'm using 3.8 miles per kwh which is not bad given the fact that most of the trips I cover is done on motorways at legal speeds.
State of health of battery still showing 100% for me according to the main dealer service sheet and I haven't noticed any significant quality issues with the materials used inside or outside of the vehicle.
Next year I'm expecting to cover just under 100k miles so will give an update on that one.
Really surprised with this vehicle. Was expecting it to fare quite a bit worse tbh.
Will be looking to get an updated mg5, mg4 or Hyundai ioniq5 by the 2025...
I would love one of those , wonder how much one with 100,000 miles would be? Much better than my 121000 mile leaf 30
Apparently it's worth 10k, but you can pick them up for really good prices now.
@@Jamesandkateat 10k that's a bargain
What's your thoughts , been looking at an older mg5 or Renault Zoe 52kwh , they seem about the same price , which is a better car? Thoughts please
It may be worth doing a video on servicing by companies such as Cleaverly as a lot of people think it will invalidate the warranty also some people are concerned about software updates.
It has been illegal to force service at dealers since October 2003, you would think people would know it by now!
As long as you don’t charge it at a bp pulse at 90p kilowatt! I have an electric car and it’s shit
Well done! I just wished all the disbelievers would take it in to!
They don't watch this sort of factual content, it doesn't suit their rhetoric 😔
Will be interesting to compare this to my Peugeot E-expert van next time Smithy comes to service it as it is coming up to 2 years old and done 70,000 miles currently.
I think it’s lost about 2% battery, still on the original rear tyres and changed the fronts around 56000 due to a puncture with 2mm tread left. .
That's good mileage. Ask him to take a picture of the pads when he pulls them out 👍🏼
Great stuff! That brake wear comparison was spot on. How much DC charging did that vehicle get?
Loads. Most days in fact.
Really great to see and reassuring as an MG5 EV owner, thank you. In terms of storage for tools etc, would you consider adding a roof box, or could this have too big an impact on mileage on long journeys?
I think the drag would outweigh any gains. Also, security would be an issue. If we needed the extra room is probably look at a van.
Thanks for sharing driving experience in real world working environment. That degradation figure is fantastic. I've seen much more on my first gen ZS EV but we do live in Queensland with super warm/humid summers. Keep up the great work and so sad we don't get these MG5's down here.
Thank you very much for your update James. The drive battery health and tyre wear was particularly interesting. I don’t own an EV yet but I’m constantly looking at what’s around. Where I can discretely inspect them I do and have noticed creasing forming in the seat bolsters of the MG4. Are you seeing this and if so is it a cosmetics thing rather than the bolster loosing its integrity. All in all your video is such a confidence builder for those sitting on the wall. Thanks for your Chanel James and Kate.
I personally haven't seen this but the MG4's are still quite new. The seats in ours seem ok but they are leatherette and we use seat covers. I'd expect if this is an ongoing problem MG will revise them on later models.
Why are you calling it a 'traction' battery? Does the car have a separate battery like a Tesla model S?
Yep, traction battery for making it move and a 12v battery to power 12v systems
dont batteries degrade over time and especially if they are just sat doing nothing. i had a zoe and did 50000 in two years and battery was at 98.8% and i abused it ran flat and charged to 100%
Yes they do, but it's very slow. Throughput is the main cause of degradation.
We have just ordered our first EV an iX1 20 xLine. As a former ice technician, I can appreciate how much lighter ev's are on parts and consumables. I think the media wants to put ev"s down as it's a new technology, and Tesla is a disruptor, and legacy manufacturers have been blindsided by the Chinese and Tesla
I had a very short spin in one, it was lovely. I think you're right, the industry is going to struggle to keep up with Tesla and the Chinese manufacturers, and regardless of what people say, they're selling well. Interesting times 👌🏻
I’m glad you like the MG5!! It’s a very good looking car, but it’s not for me!! But there again, it’s more likely to be seen with a taxi driver!! They’re used by the taxi company in Harlow!!
Yep, taxi drivers seem to love them 👍🏼
Come 200k(?) I'd be offering the car back to MG (For a reasonable consideration) just so they can show it to any potential buyer worried about longevity.
Even taking it around the car shows in a "used" condition with a picture of the odometer on the front would be a great advert.
.
(I bet it ends up as your company "emergency transport")
I do actually do that when the cars displayed. A little print out with currently mileage and costs to date. It goes down well.
I been in absolute budget EV taxis with 400-500k km in China and they are fine.
SAIC knows what they are doing and people will figure it out soon enough
I’d consider one of these, but sadly the local dealer is Richmond, total bandits to deal with, can’t get anything right, think nothing of having you off the road for 6 weeks at a time for simple stuff
Fair, and a shame. There are other options for servicing and repairs however.
@@Jamesandkate yeah true, I had a Hyundai off them, literally everything the touched was awful, admin errors, lies, damage, doing work in the wrong car(other customers repairs on your). Had to chase continuously to get warranty work done. I eventually cut my losses as it was a full time job dealing with them. God forbid you had a serious issues that needed them to act in anything quicker than months . Keep up the great vids
Hi James
Love the channel. However I would bring to your attention that 100,000 miles in 2 years is not the same as 14 years for the traction battery as batteries deteriorate from 2 things; charging cycles and AGE i.e the chemistry of the battery deterioates due time since manufacture as well as charge cycles.
Indeed, but the degradation curve of NMC, that's well documented, should show only a 2% variation over this time. We have 10yo 300k mile Teslas with over 85% SOH
Correct but it looks like a really good start .
@@Jamesandkate You can't extrapolate that beyond a certain point. The degradation curves are based on chemical processes with steady kinetics, and even though not all the process are fully understood, their sum total is pretty predictable. The problems come when you have processes occurring that aren't linear with time. A good example is electrolyte loss, via diffusion though seals. Though the loss might be fairly linear, it's effect isn't: The SoH remains constant whilst there remains enough electrolyte to transport lithium ions (there is always a little excess in the battery), then when the cell gets dry the high rate performance (max current) will drop a bit, but it won't affect capacity, and then the cell will just suddenly die when a specific threshold is reached. And this is just one example - there are other sudden-death processes.
Just popped on the feed - 100k miles in two years and the only observation is the dirt!
4 years on my Mk1 ZS EV, just topped 60k miles, so this is definitely giving a lot of hope for 150k+ miles regarding the battery and motor, then I'll replace with something a bit more fun (after it's saved me £15k on petrol).
I've had some seat vinyl tearing, and some self inflicted problems (broke the false floor in half) but apart from that very easy work for the MG EVs!
Coming up to the 4th year service, so definitely will give you a call when the time comes around 👀
That's good going and well over average mileage. I've seen plenty of ZS EV over 100k so you should have little to worry about. I'll get it washed too 😉
@@Jamesandkate I'm the last person to complain about the dirt on yours, you should see mine! 😝
Just wondering how Tesla charge 30 to 40p per Kwh when all the others charge 79p round here in Suffolk. Does Tesla get cheap electricity or is it the usual rip off Britain from the major suppliers
Good question. Tesla are passing on the actual costs to their users. The price per kWh wholesale has been 11.3p this year. Basically, other CPO's are charging for their investment costs.
@@Jamesandkate Ahh. Thanks for that
This really shows that the Chinese are making good quality cars now.
kl9518 Apparently, the Chinese are the world leaders in mass hypnosis... just sayin'...
😉
Motorway high mileage doesn't cause too much wear and tear!
City driving high mileage cause extremely high wear and tear!
That's why people don't buy ex-taxis!
Potholes, humps, stop/start traffic, braking and endless hard turning and u-turns kills the car!
It may not be an issue yet for MG's but I almost crashed a 10 year old Mercedes because one of the rear brake pads fell apart. The friction pad separated from the back plate and my brake pedal went to the floor as I drew up behind another car. I was lucky and got stopped in time but it was close. I can only assume it was rust/corrosion that caused it because the pads had loads of material left so as a mechanic this is something you should bare in mind when working at older cars.
On a happier note largely because of the great reviews from James and other RUclipsrs I bought a used MG5 and so far love the car.
This is an ev servicing company advertising how little service ev needs.
Exactly that. Must be honest then?
Looks like MG have missed a trick by not offering a van version
So true, they'd sell bucket loads
This MG it’s strong, relieve and cheap… 💪
Imagine if you could get petrol at half price if you bought a specific brand of car? In the EV world that's Tesla and quite an important fact to consider when choosing which EV to buy. Between ICE cars and EVs there's no contest, 1/6 of the fuel cost for and EV if you can charge at home. If you charge at home most of the time the Tesla half price charging is not as much of an advantage.
perfect video as always mate, all I hear now is brake particles, usually I ignore but sometimes I bite. This vid is perfect. Keep,well 🙏
Thanks, John. Hope you're keeping well.
I am very pro-EV and have an MG5 LR myself. At 7:24 you say that 100k miles over 2 years and over 10 years is the same. Not exactly, as lithium batteries chemically degrade even if they are stored at 40% in a cold place and not used at all. It's not going to be a huge amount, but just cycling the battery/energy throughput alone isn't the only predictor for wear as average temperature, age and average depth of charge/discharge definitely has a bearing too. Do you know anything about 12V system issues on these cars?
I love these style of videos, one thing for sure, when i ask you guys to service my Tesla we can't exactly get pally as they only need servicing once in a blue moon. :)
tesla charers v4 opening to all soon
This is the long term review I was waiting for. It confirms what we all know about running EVs - they’re streets ahead of ICE, period
I had no carpets and no furniture for almost a decade and rented two rooms out to pay the mortgage. Spare money is not falling from the trees
A rather random comment. Are you okay?
When you have some spare money you'll know these are a good buy.
Great James keep up the great work. Was looking over Steve’s when he was servicing our cars. You battery is the same SOC as my Ioniq at only 25000. Hope it stays at that for a long time. I would be getting very nervous about an ice car at 100000.
Love our MG5, but boy oh boy, the software is rubbish (when you can get android auto to work!) is there a firmware update that i should ask about at my next service? Otherwise, purely as a car cant fault it. Good to know how well yours is doing.
Try a wireless connector and make sure you use a genuine lead.
Picking up James' point regarding the traction battery doing high mileage over a short or long time. There's an arguable point, I feel, that 100k miles over 10 years is easier on the traction battery than 2 years for the same mileage, especially if you have a battery that hugely prefers lower charge speeds, say in the Type 2 range of 7-22kWh. Over 10 years/100K miles you are obviously going to do less truly rapid charging. So I would say that it is arguable [not definite] that high mileage in a short period is harder on a traction battery than spreading it out over an extended time. And if true, it means that MG5 is doing even better than it already seems.
A small correction to discussion here - you can't equate 100k miles over 2 years to 100k miles over 10 years where a battery is concerned. The reason being that only a portion of battery degradation is cycle-dependent. Many of the side reactions that occur within the battery are more strongly correlated to temperature, voltage and time and not to usage. And there is the slow diffusion of electrolyte solvents through battery seals, which is time and temperature dependent. It is all extremely complex, but it does mean that you can't just say that the life on an EV battery is "x thousand miles", irrespective of age. It is quite likely that old low mileage EVs will die at fewer miles driven than equivalent ICEs, whilst high mileage (short lifetime) EVs will go much further than equivalent ICEs.
So I discussed this with an electrochemist in detail. NMC has a very well documented degradation curve over 10 - 15 years. We are seeing Teslas at 10yo and 300k miles retaining 82-85% of their original capacity. Basically, throughput appears to be the main concern aside from long periods of high/low SOC where abnormally high levels cathode degredation can occur.
@@Jamesandkate Interesting, as i am also in battery research. And we find that whilst the degradation curves can be quite reliably modeled as you say, cells (both those we make and those we test for others) will eventually tip over from that well-understood linear-ish degradation to a more rapid "sudden death" type performance drop-off that is very hard to predict. I would also say that very few people have batteries that have been on test for 10+ years. Many predictions are made on the basis of accelerated testing, which is not really a great way to find such sudden-death phenomena.
Probably the best data comes from non-automotive sources such as stationary storage and marine, where the battery supplier has much more comprehensive logging data (and they have been running for a lot longer than you might think because they stay out of the media), but they operate the batteries under much tighter conditions of temperature and SoC window than you will see in automotive, and then they get absolutely crazy cycle-lives.
Thanks for the video, good to know you’re still a fan of the MG’s. I’m just hoping for MG5’s and other MG’s to get free software updates to be able to charge at the (non) Tesla charger network, I can’t understand why we seem to be the only car brand that isn’t able to do so right now.
As far as costs go these cars are not cheap as chips to run though are they. £36000 new and after 2 years and 100,000 miles what is the depreciation. I shall give you an example. VW golf diesel over 2 years depreciates around £5000. The equivalent VW EV depreciates £19,000 in 2 years. That makes the running cost out of most famies reach. Be interesting to know what your depreciation is on that MG
There are several expert articles where battery aging is distinguished by mileage and age precisely because of the slow but measurable change in battery chemistry over time.. I don't know where the truth lies, but the problems with older batteries in the Nissan Leaf may indicate something.. The second thing is corrosion protection , which all Chinese cars have bad, unfortunately not even Ford is a winner :-) For me, something else is more important: MG is the Chinese communist state factory SAIC, which financially subsidizes the production of MG, financially favors the purchase of the battery, furthermore, the production is not ecological and China supplies the parts Russia for arms... May it is time to support "west" ev's more than from china ...
I have a 2020 Nissan Leaf e+ that has only done 12000 miles in 3 years yet for the past two services and recent MOT I have had an advisory on the front disks due to excessive rust. I am going to get these replaced as it is a lease car but Nissan have quoted £480 to replace these and the pads. I had another Leaf before this that did 30000 miles without any issues. I can't help but feel this is due to inferior materials but no chance of brakes being under warrenty. The dealer has said it is probably lack of use of the brakes that has caused the rust build up.
Do you use e-Pedal with B mode enabled? If I were you I’d fully charge the Leaf to 100%, turn off e-Pedal, place in D mode and do some hard braking in a safe area. You’ll probably clean off the brakes by doing this as regen is basically nil when the battery is 100%.
We charge £180+vat for front discs and pads on the Leaf, and we come to you. The pads 100% need greasing or you will suffer corrosion.
@@trainingtheworld5093 Thanks I did try that, or very similar, for a few days before my last service and it did clean the surface of the discs but not enough to stop them still being an advisory.
@@Jamesandkate Thanks for the response I have sent email to Cleevely to discuss further.
Sorry, since my post, I have to add that they changed (allegedly) the brake fluid. This raises 2 questions the first being really? After just 2 years and what environmental impact will this have disposing of the waste? Secondly, whatever happened to taking a hygroscopic reading, to determine the health of the fluid?
Two years old 100,000 miles my car has done 74,000 in 13 years . £40 per month why would i want to buy a EV. If hydrogen comes in id probably buy one . The only thing is my car is dated. 58.9 mpg.
I'm sorry but it has to be up for debate, whether mileage over a short period is different to mileage over a long period.
I find it very difficult to believe 100k miles in 2 years didn't necessitate almost exclusively rapid charging, which would not be necessary with the same miles done over 10 years.
And of battery failures that do occur, habitual rapid charging seems a common theme, with prior degradation giving no warnings.
Hi @Jamesandkate,
Can i ask if you charged these earlier MG5s on Tesla superchargers, and did you need to do anything to achieve this?
I got a "vehicle not recognised" notice, and it wouldn't charge.
50k out if a set of tyres? Had to change my front ones a 18k, about the same as an ICE powered car. Tracking is fine and i drive pretty smothly. And we're being told EVs use more tyres due to there weight.
Who cares? I'll never buy an EV.
@colinaldridge259 I rather enjoyed the video, quite enlightening. It would appear that EV owners have a problem with calculations. James isn't sure whether his van has done 100k, or 200k @6:08 understandable though, as James can't count above 3.
Let's assume tyres are apples for this simple adding up sum.
If Kate gives James an apple when the vehicle is new, then gave him another apple when the vehicle had done 50k, then a further apple when the vehicle had done 90k...
How many apples did Kate give to James...🤭
Does anyone have my issue? The charging cover stop closing, the pin stop clicks! And how much cost to fix it! I've got this problem from a week and using a tape to keep it close!
100k in 2 year isn’t the same as 100k in 14 years with average usage. Time matters to electrical and mechanical things. Time will expose different failure modes.
Love it James. Big up yours to all the EV haters!
After watching your video's, I'm converting to EV. I repent my past 🙏
I don't agree: age is also relevant for each part of the car. The car in this video drove many miles in 2 years and it drove in better circumstances: it was warmed up more and all condens could evaporate. Rust is also not an issue. However: your car will probably come on de the second hand market with an altered odometer.
Defo makes me put MG5 highup on the list of considerations for my first EV. I refuse to buy another ICE car, just not doing it!
I was about to say this was a good bit of STRESS testing but come to think of it, it is not :)
I have to disagree with you on it being "not up for debate." Leaving the car at 100% or 0% for extended periods does damage to the cells, which could be more prevalent in high mileage over a long period of time as opposed to high mileage over a shorter period of time
Morning James got a quick question regarding my niro. Ive been waiting for 6 yes SIX months for a new electric motor as mine has gone gaga (getting louder and louder as time goes by) if my vehicle breaks down and appreciate the costs would be down to me (its still in warranty) what would we be looking at for a replacement/reconditioned unit please? Cheers
Hi. I actually have no idea on a recon, I think second hand would bve the best option. Was it the motor or reduction gearbox?
@@Jamesandkate The mounts was replaced last year so I confirmed with TMS and it’s the electric motor that’s being replaced
I have a MG5 LR and I asked for the tyres to be rotated at the first service at the main dealer.There was a lot of hissing of teeth,as they said that would be an extra £180 as the TPMS sensors wouldn't be in the right corners etc. It was just a query so I left it,and will just do my usual fitting winter rated tyres and keep the originals.I think you just swap tyres and rims back to front and vice versa,but it seemed that the dealer was not keen or just looking for more £££.
Yep. Tell them to mark the wheels and swap them.
Thanks James.My previous ZS had a rim swapped by a third party tyre garage by mistake.Only found out when I picked up a massive puncture.Does your company come to Aberdeen and does it effect the warranty.Im getting brassed off with main dealers.
Great video vehicle sounds great can you tell me what the battery chemistry is the MG5 is not available here in NZ
would the MGZSEV have similar reliability and longevity
Thanks
cheers 8:54
Hi, Battery is NMC on LR and LFP on SR. That should be the same for all models worldwide
@@Jamesandkate thanks for the reply
I assume your vehicle is LR
Thanks cheers
Chinese rule the world of Evs. A great video and Saic motor seem to be the only company selling a fully electric estate car - come on other car companies your way behind!
Does anyone know if alternating the wheels to even out tyre wear affects the tyre pressure monitoring system (TPS) on an MG5? Thanks
Great vid. Will be doing a vid on the Tesla once its done 100k. Not l9ng now 🤓
Look forward to it. If you need a traction battery SOH we can facilitate that for you 👍🏼
I'm sure you and the team have considered it, but have you considered a maxus t90ev with a utility/service bed on the back? Rubbish charging curve, I know (despite the 90kWh pack), but there might be some tax advantages to the pickup truck, and it might give options for more kit in the back. Back in the day the AA used the venerable Vauxhall Brava pickup (Isuzu underneath) for the same job.
I'm just doing a review on one that we filmed last year. It was a poor vehicle imo and certainly no good for us.
Brilliant matey 👏 👍 👌
Cheers boss 😘
I don't agree that battery will degrade the same after 2 years and 100k miles or 10 years and 100k miles. Battery will degrade over time slightly, especially if it was not kept at around 50% soc in time when it was not driven. But anyways, these are great results so far and crazy how pads and rotors can easily last lifetime of the vehicle on EVs
Correct. Li-Ion batteries have a shelf life regardless of use so a two year old battery will be in much better shape than a ten year old battery for the same mileage.
There is an element of time based degradation, however, we are now seeing 300k Tesla running NMC at 85% SOH. The curve is normally 5% in the first year then a very steady decline. However, thoughout is the main culprit for degradation.
@@Jamesandkate There's no doubt that battery technology has improved immensely, including shelf life, regardless of chemistry. But there are rather few 10 year old EVs on the road and even fewer at 20+ years old, so the real life data are just not there yet. I think we just have to recognise that degradation over time is a fact and that will disproportionately affect low mileage vehicles that might otherwise have 20+ years of useful life.
You know that you can charge non-tesla's on the Tesla network now? As long as you have the CCS2 connector and a smartphone app.
Congratulations for your review 👏! Could you please share us how much you usually charge the battery (80% / 90% / 100% of the max load) ?
Hi. 100% 5 nights a week and regularly rapid charged.
Great vidioe sounds like its load of crap about MG only lasting a couple years withour breaking down.
My id.3 eats tyres. I don’t rag the car either. We’ve had 6 new tyres in 2 years. Also picked up a couple of punctures. Lucky they are covered in our lease. But the car has been great. Very cheap to run.
I have been told the same thing. I believe they start with less rubber too.
Thank you James, we own one and love it. When you rotated the tyres did you have to reprogram the TPMS ?
Nope. Just mark the wheel position and only move back to front, not across the car. The TPMS will be in the wrong position but it's not to hard to see which one has a puncture.
I'm glad he said £0.018 per mile when you're charging at home. Interesting data. Important caviat.
Approx 60% is home charging for all 4 technicians.
If you think you might buy a MY - remember that the stalkless wonders are threatening James/Kate.
I'd 100% buy used, with stalks.
@@Jamesandkate I’ve had enough of the embarrassing association and looking at MG4 (77) as a replacement for our M3.
shame MG dont do a small van or there is a market to convert these into small vans, but tax is better on vans. zoe does a 50kwh van
If they did an MG5 van we'd 100% buy them
