ZS EV LR battery care

[MickeySw]

It's confusing because it's MG's terrible English localisation again. It barely makes any sense.

Agreed, but it talks about a HV battery maintenance procedure that is recommended to be done 4 times per year?

That's not battery percentage it is referring to though, it's refering to the power of the charging itself.

10% of what power though?

It's just trying to say to not do that full charge on rapid charger, but a lower power charger.

Doubt that, as it would mean balancing only every 3months?

That sentence is not in the ZS manual btw.

It’s in the one for the MG4 and MG5 though?

At the end of the day it’s just a recommendation, no need to loose sleep over it

" or L Grid" I assume refers to Local Grid - effectively your AC 7kW power supply. "Lower-power" than a DC rapid charger in other words.

I just think this has come out of nowhere, that's my point.

And yes, I agree there's no need to lose sleep over it, which is why I posted earlier in thread to say "just drive the car". For most people you shouldn't need to worry about all this, the BMS should be looking after it.

I'm a relative newbie, having purchased my EV late last September. I've read through a number of threads, and I'm still not sure I've got the right answers for my specific car.

According to a post I found elsewhere, the MG ZS EV has the LFP battery and a 330km range. Expected to last 3000 cycles.
The MG ZS EV Long Range has the NMC battery and a 440km range. Expected to last 1500 cycles.

So if I have a 2023 plate Long Range with sunroof (I mention this as I'm not sure if they've changed the battery with later models), I've got the NMC battery right? Is it genuinely inferior for the number of cycles?

So battery care. I've been charging my car in the range 20-80%, using a Podpoint Solo at home charger charging at 7.4kW, except on rare occasions when I needed the extended range and I charged to 100%. Is that right for my battery?

Balancing charge. I consistently use the Podpoint charger at home, with the car set (not the charger) to charge to 80%. Will this initiate a Balancing Charge? I thought it did until I read recently that you have to discharge to under 10% first?

Finally, battery heating. To date, I've only used this feature a couple of times, but I wonder if I should be using it more. If so, at what range of outside temperature should I be using it?

Sorry for lots of questions, but I wanted to nail it all down in one conversation.

After read and watched lots of videos on this it was summed up by Dave takes it on that the battery will probably out last the car which will fall to the rust demon before the battery starts so any loss. As you have a long range only charge to 80% unless going on a long journey next day. My one is a short range with LFP so 3000 x 200 = 600,000 miles not even a ICE can do that with out major overhaul of the engine.
