I haven't seen any real rust issues on the ZS EVs. There are a couple of videos on YT showing very mild beginnings of rust to some underbody seams towards the rear of the cars, which iirc were between 1 & 2 years old. This was not bad & not unlike you get on quite a few other brands of car. If...

This might be totally wrong but I had the impression only one MG app could be logged into the cars account at anyone time! Try logging out of your account & make sure the other MG app is logged in on the other phone. I think it's a safety thing. You don't want some else having control of your...

Couldn't agree more Tuareg. Don't stress about your battery. It'll be fine but just do your best to look after it if you intend to keep your car for a very long time. (y)

My Zappy charger gives me the full UK 7.1KW as it charges. But to do a full equalisation, going down to about 18 or 19% it overuns to normal electric prices. That's fine by me as it's not by very much. I was told the charge had to be a full uninterrupted charge & to turn off smart charging...

Ok so I'm back. This seems a requirement to remind everyone that MG customer support here in the UK has told me exactly the same thing (as I have previously mentioned in more than one thread) as told to Joningy. That is with the exception of the blue & green lights, which if you think for a...

This sounds totally unacceptable Dave. Any chance they'll give you a courtesy car? I'm doubting it.

Hello Steve, no it makes no difference what setting the KERS is set to. ACC doesn't use KERS at all while it is engaged.

Hello Martinonline, what I said about my recent meet is LISTED BELOW. It does include I think the information you are complaining about not being there. Although I'm not sure what you mean by 'the first person' info. I suspect you are refering to the LFP MG which surely you know has to equalise...

Actually Martin, if you read my earlier post about my meet with others, it's all explained about who could & couldn't equalise at below 100%. Read & digest! It's quite easy to understand so folks can see the facts. We discussed at some length the situation regarding these interesting facts. As...

Thanks siteguru.

What car & what type of battery James? Why are you dubious? In case you didn't notice, I haven't made any suggestions.

I don't think so decrep. I was at a local MG EV meet a few weeks ago. There were just 6 of us consisting of 2 x ZS, 1 x MG5 & 3 x MG4's. All cars NMC except the MG5 & 1 MG4. The two LFP lads could easily equalise at 100%. One of the NMC MG4's could equalise from any soc as per what is being said...

Yet you are not correct according to the way my car charges & many others, whether MG4 or ZS. We have MG4 owners coming into our ZS forum telling us their NMC batteries won't equalise at any level except 100% & they need to take the state of charge down to 10% or lower to trigger the BMS to...

Y Not being rude but you need to read the thread.

Yes indeed! My NMC battery appears different. Yes, I know the difference between equalisation & calibration. Often misinterpreted by some.

Yes, you are looking at this from a technical engineers perspective, so I do understand where you are coming from Roger. Strictly speaking you are correct when compared to some other types of battery. And your description of the equalisation event is again perfectly correct. The main issue for...

It doesn't sound bad at all Alison. Most of an EV's initial battery degradation seems to happen in the first year or so then it starts to settle down. So no need to concern yourself. Rolfe's degradation is similar also. We have 5 EV's in our family with differing chemistries in their batteries...

Excellent news. Well done.

Rolfe, I've already said this & it's fully acknowledged. I refer you to earlier posts. Anyway, this is pointless if people actually don't read the thread so please have a great day. Thanks & I'm out.

Sure, will do Martin. Won't be tonight or anytime early as am in hospital most of tomorrow. But will sort it later in the day. It's very clear in the manual by the way & is just as MG customer support tells us to do it. It works on my late ZS every time.

Yes, the EV version was not brought to the UK right away even though it had been already released elsewhere mostly in China.

No you misunderstand. Quite a few MG4 owners were agreeing with me regarding the fact that not all MG4's were capable of equalising in the same way. There are differences in the way they need to equalise. The thread appeared split in opinion amongst both MG4 owners & ZS & MG5 owners. It wasn't...

No, nothing incorrect, I'm just repeating what we were all told by some MG4 owners who were in the ZS forum about their equalisation experiences a while ago. And this was great to hear & a good exchange of info came out of it. Seems even you MG4 guys, like many ZS guys & girls, couldn't agree on...

Yes, that's all correct Gary for many of the MG4's & some earlier ZS cars. I have the long range ZS with an NMC battery (72.6kwh). I bought mine new at the start of this year. These cars are unable to equalise or balance unless the low battery warning comes on at 20% soc. Best to take it down to...

It seems to be the other way round now. This has been confirmed by the owners manual & MG tech support. I've tried it every way & the ZS has to get the low battery warning before the BMS will initiate an equalisation. I think the earlier ZS's were different & the MG4's seem to be a mix of...

There are no stupid questions dsr. Yes, as Tight Git says you can check your charging curve map on your charger or car. It will show a gradual reduction in kw's going into the battery from 7kw's gradually down to 1kw & 600w, 300w etc etc until the charge is completed. Mine takes 10-12 mins in...

I think there is also a bit of a difference in car software between the MG4 & ZS EV. My car is the ZS. My car requires charging all the way to 100% before the equalisation charge can start. Some MG4 owners say their cars can equalise at a lower soc, albeit it won't be a full & proper...

I know this is an old thread but incase someone stumbles across it I thought I would add comment concerning battery equalisation using Octopus Intelligent Go. It's possible by now some other thread may already have disclosed what I am saying below. There is still some confusion on this subject...

That's excellent Lovemyev. Congratulations on the new MGS5 purchase. I'm sure you will love it. Just a little point I'll mention re the ZS EV not that it's that important now but incase newbies or future secondhand prospective buyers don't know. The ZS was right from the start designed as a...

Yes, BL cars suffered terribly from the dreaded rust. Ford had similar issues too. Look how quickly some of the BL models disappeared from the roads. I was there looking at their processes amongst other things. They had no money...that was the basic issue mostly caused by bad management & unions...

Lovemyev, as I've said repeatedly, I get a pretty accurate GOM reading. I've repeatedly recorded my actual mileage covered compared to my predicted GOM range. Of course it's not always right because my journeys vary. But overall it comes very close most of the time & sometimes gives more than...

Thanks Paulie for pointing that out but you clearly haven't been present at a car factory when sheet steel is being delivered. And it certainly isn't an April fools type joke. When I've seen this the steel was already quite rusty. Albeit this was a few years ago & sure processes may have changed...

It's been known for some manufacturers to use steel that has not been 'weathered'. As some will know this process involves stacking sheets of steel used in the production of cars out in the weather, unprotected from rain etc. Some manufacturers even spray the new steel with salt water to speed...

This was taken this morning after an 80% charge AFTER my wife got back from the shops. This was in NORMAL mode! Before she left it showed 234miles. It dropped from 240 odd as we put the cabin Aircon on full for a while before she left for shopping. Trips reset before charging. EDIT: Just as I...

TBH, I've never ever had a predicted range at 80% in normal mode as low as yours even after resetting the trips. After a reset I normally get a guesstimated range in NORMAL mode between 232 to 235 miles & even close to 240 on very warm days. In eco it's often about 10 to 12 miles more in a...

Yes, John I find by NOT resetting the trips I actually get a more accurate driving range on the GOM because the car knows how I've been driving. If you clear the trips the car doesn't have that info & has to make it's guesstimate based upon default battery capacity algorithms & temperatures...

When I clear the trips I get slightly less range showing because the car has no previous driving style to go by so I find isn't as accurate. But what does happen is the car adds miles to the range as I start to drive. So at 80% with no trips reset my car shows between 225-230 miles. I drive 12...

Lovemyev, Just to say I charged to 80% last night without resetting trip etc. My predicted range this morning is showing as 242 in normal mode. When flicking to eco this adds 13miles...so 255 miles. I find NOT resetting the trips gives me a far more accurate range prediction as the car seems to...
