Battery balancing and battery life - fast or slow charging?

[Data]

@Data, I do not think this thread is in the ZS Forum but rather it appears to me to be in the General Chat Forum. I note that the Similar Threads list at the bottom of the page does have a majority of ZS links.

I am confused by the first sentence of your second paragraph. Are you referring to my car's battery, or is it a typo that implies it and you are just making a statement about LFP batteries in general?

Lastly, could you please tell me how, other than seeing the the low battery warning message, that the car has been fully equalised? I will try in September when I'm due to travel over 50 miles in one go.

I thought my profile shows me driving an MG4 with Trophy Mk1 added to my location. Is that not what you see?

@siteguru, the images I posted are not from my car but from posts to the MG4 forum.

Hello Martin, yes I'm sorry. It is of course the General Chat Forum & not the dedicated ZS forum. My bad.

I did actually assume you had the MG4 with the LFP battery pack. Many long range MG's with LFP's have adjustable battery health levels on the infotainment screen, like the MG5. I didn't know they even did an MG4 with an NMC. So I've learned something.

The best way to be sure the car is properly equalising is to watch the car wall charger screen (if you have a screen on yours) to see how the wall charger ends the charge. Or watch the charging app for your wall charger so you can see the amount of power being delivered at 100% soc. It's best to turn off any smart charging you might be using & let your wall charger control everything. That way the smart aspect of your charging won't interrupt the charge. If the battery is equalising the charge should slowly step down bit by bit at 100% until it reaches a level of charge around 0.3kwh, 0.2kwh, holding that charge level for anywhere from 10mins to even an hour or two. If the battery is very unbalanced it might go on for several hours. A friends car balanced for 3hrs when he did his first balance. He realised he'd never done a proper full charge one before, relying on just the little balance that occasionally occured at 80%. The good news was that the car gained an extra 28-30 miles of average range after the equalisation was complete. At least that's what he had calculated.

Your profile doesn't show you have an MG4, just the Trophy trim level. Hope this might help.

Fair point. But your signature says you have an MG4 Trophy - so my NMC comment still stands.

Siteguru, where does it say in his profile he has an MG4. I don't see that. It just says he has a MK1 Trophy.

And his signature under every one of his posts shows:

Are we talking about the same forum member?

I see that there are 2 ways to access a poster's details, via the header of the post and via the avatar to the left of the post. (Note that with mobile phones this avatar is only visible with the phone in landscape mode.)

I will amend my location details to make them similar to @siteguru's who include their full car details on their location.

I think we have exhausted this discussion but @Data you may like to view the battery discussions on the MG4 forum, particularly by @T1 Terry.

Ok that explains it. I'm on my phone doing this most of the time in my workshop. Thanks everyone.

well that seems to be some of the confusion cleared up, TGFT

Yes, I see battery discussions are all over the forum. Seems to be quite some confusion in some quarters, especially about battery equalisation. I think this forum is doing a pretty good job of helping to point folks in the right direction.
