Conditioning charge

[Jonknee]

For the life of me, I cannot find in the manual which type of battery pack is which. It refers to type 1, 2 & 3 and I am assuming I have type 2. Tried searching the forum - failed at that too.

How does the charge to 100% once a week compare with the 80% battery health mode if you are in fact only charging once a week? Slightly confused.

According to below you have an NMC battery chemistry that should only regularly be charged to 80% if one reads the manual, (although in reality it’s perfectly fine to let it go to 100%)

MG MG4 Electric XPOWER

All details and specs of the MG MG4 Electric XPOWER (2023). Compare price, lease, real-world range and consumption of every electric vehicle.

A top up to 100% is usually recommended to do cell balancing, however unlike most EVs, the MG4 will balance at your set SoC limit (e.g 80%), therefore there is no need for a 100% charge.

How can a charge of 80% activevate cell equal electron distribution. As far as I know each negative and positive plate has to be must be at maximum capacity.

Balancing is done on a cell voltage level, doesn’t really matter what value that is but let’s assume the lowest cell is @4.000V after reaching 80%.

The BMU then tries to discharge all higher level cells until the difference is minimal (usually < 0.001V)

Obviously the bigger the difference at the start the longer this process will take, doing this regularly keeps balancing time short.

Thank you, understood.

Although I normally only charge to 80% due to the app showing this as battery health mode, I still can’t find where this is explicitly stated in the manual as recommended.

Somewhat confused ? - After 4 months of ownership I'm still surprised how easy it is to confuse me ( line up 3 shovels, tell me to take my pick ?!?!?! ).
I was convinced from what I'd read and seen, my SE LR had an LFP battery. I was happy with this as this was what I'd had in my Kia Soul with no degradation over 5 years and 48k.
Then, reading earlier posts in this thread and doing another 'google' I came across the attached. And no, the SE LR is NMC apparently ?. But this is ok as it's a more tolerant chemistry.
And as for type 1, 2 or 3 - I can find references to it but no spec ( more ?) ..

Yeah, I dig that man, heavy.

SE is the trim level, across two battery chemistries.

I'm more surprised by your Kia Soul comment because I'm pretty sure Kia only started using LFP batteries very recently and not on the Soul. I thought the Soul used an uncommon Lithium-ion polymer type of battery.

And THAT's how confused I am.
Think i've finally reached the equivalent of my parents vs VHS recorders.

So what type 1,2 & 3 all about then ? I'm presuming it's not sr, lr & er ?

I'm more familiar with "Type 1" etc. being used for chargers/cables.

MG4 has type 2 AC and DC rapid (which sometimes gets referred to as type 3).

If you mean MG4 model types then the admins/moderators will know more than me because they have to work out the different models!

I actually presume that it is that.

Type 1 = 51 kWh LFP = SR
Type 2 = 64 kWh NMC = LR
Type 3 = 77 kWh NMC = ER

 

[fnegroni]

type 1 is 64kWh NMC
type 2 is 51kWh LFP
type 3 is 77 kWh NMC

 

[siteguru]

So 1 and 2 are opposite to what I thought? ?

 

[fnegroni]

Yes

Thank y'all ??
Glad to see I'm not the only one somewhat confused ?

I remembere the good ol' days of leaded, unleaded, diesel and ripoff variants thereof

To go with BBC1, BBC2 and ITV ONLY!! SKY? Ptah!! might as well be dancing in t'wheatfields ?

ATV ? Tingha and Tucker ?

Not forgetting the days I ran my Renault Clio van on Tesco’s cheapest veg oil ?

To get this slightly back on track…..

Can someone, hopefully one of the knowledgeable contributors above, please link to where battery packs type 1,2 & 3 are definitely defined and to where the 80% recommendation is referenced.
I cannot find it in the manual (that comes as part of the iSMART app). Hopefully will help me and anyone else that finds this thread after an internet search.
Thanks!
