Battery chemistry

[itsmesteve]

Can anyone tell me what battery chemistry is used in the (traction battery) of the 2022 ZS SE LR?

I have emailed MG and apparently they can’t help and have suggested I ring the dealer, but I’m not confident they will know the answer, as they’ve been a bit vague on some less technical questions. I have googled this and have found mixed answers… NMC and LFP??

Many thanks

Long range has NMC
Standard range has LFP

Great thank you, that’s really helpful… I’m just trying to work out the best way to manage the battery health and our charging routine.

Use the search bar as there is a lot of information on the subject.

Personally I think people are overly cautious of managing charging, I've had 2 Nissan Leaf's and used a 3rd, plus a HS Phev and now have a ZS LR TC with all of them I've charged them when I need to, always charged to 100% when I can and never had any noticeable battery degrading. The Leafs and ZS have had rapid charges when needed. The ZS is probably too early to say whether or not the battery is going to degrade. But for me I bought a car with a range of 273 miles but if you only charge to 80% and recharge at 20% (to be fair I've never run it that low yet but the leaf I did and lower) you're already at 160miles on a perfect day.

Don't get me wrong, I have a Discovery that does 500miles on a full tank, but on a long run I tend to fill it at qtr tank, so really only get maybe 400miles max and these days that costs me the best part of £200!! So no vehicle gets the advertised range, but I don't see the point to reduce it unduly.

I typically charge to 80% on a Monday, as I know that I'm only doing short runs. Then 100% on a Friday, ready for the weekend

That's with a Trophy LR, I don't worry about degradation, but my routine works for me. I get free charging at work, that's the biggest driver in when I charge

Sort of my point, you have a pattern that works for you, based around your routine more than the battery management.

Don't worry about it too much
From what I've read, leaving that battery at 100% for extended times is one of the things that can reduce battery life, so if it suits you, charge to 80% unless you are going to need more.
It really is a personal choice depending on your mileage and what charging you have access to

That is a fair point, when we went away for 10days a couple of weeks ago, I deliberately left the ZS at about 60%, then slung it on charge when we got back.

Thank you for all the info and feedback. We took the decision to buy the long range version so we’ll definitely use the full range as often as we need to (albeit we seem to be getting 250ish not 273). I’m more thinking about how to optimise the 4 hours or cheap(er) electricity from Octopus Go with our commuting needs and where possible what’s best for the battery longevity. We’ll probably end up doing 3 or 4 x 4 hour chargers a week with the odd longer charge when we need it for long weekend trips. We’re lucky to have a 7kwh home charger so should only need to use any faster chargers on long journeys. Thanks again… the forum is a really helpful resource for a 1st EV driver.

I don't think about charging I just plug in every night or morning depending what shift I am doing 4x25% or 5x20% works out the same as one charge cycle and apparently healthier for the battery
