MG5 SOH

Remember it’s a best guess by the car.
The only way to be sure is several deep discharges and full charges

My range shows 239 but my soh is 95.6 or something

It hasn’t made any actual difference to the range I can drive

So how deep discharge are we looking at what is the % to stay with in

 

[Pebblefeline]

I run mine down to well under see 10 percent and give it a full charge every six months or so ( as instructed in the manual)

See what energy it takes minus 10 percent
Then compare that to car scanner

Otherwise I use the distance displayed at 100
Or car scanner

Honestly though if you worry about it you will tie your brain in knots (I did)

Frankly it’s still a bit of a best guess

I thought the 10-100% was just for the MG4 LPF batteries

I took my 74 plate trophy down to 7% then charged up to 100% and it took 60.42Kw just over 2 weeks ago you could see it balancing the battery’s it must have took 15 minutes when it was at 100% at various rates 4.4 3.0 1.2 0.6 etc.

Mg 5 2021 3% to 100% 58.4 kw now i have a smart charger and plan to check capacity on car scanner and then add 10kw to see what the losses are when charging.

Interestingly my manual says this

Car scanner shows i still have 100% SOH, I've just past 30,000 miles.
I'd say less than 15 blasts on a rapid charger with the rest charged at home 7kw.
I took this after a 12 mile drive, when I got to work, started at 92%.

Interesting what year is the car. Mine has SOH 95% 13000mile 4 high speed charges 3 years old

2021. It's the last of the standard range.

OK, that rings a bell, can’t remember where I came across this, but rumour has it that some SR have been equipped with ‘rejected’ LR HV battery packs, meaning they will basically stay @ 100% SoH for years..

I thought they had LFP batteries whereas the long range had NMC?

All PFL models are NMC ...

60000m service this morning, SOH 92% so thankfully a smaller drop than the previous 15000miles.
