MG ZS EV MK2 - LFP (standard range) - Battery SOH Theory

Good to see the programmed decline of 0.01% each day has stopped.

A bit surprising to see that it happened before your service already. Did you get a software update at any time?

My 2 year service is in about 6 weeks time. I'll see whether that makes any difference.

I don't think there was any software updated, I got mine second hand in April and pretty sure there were no previous updates ... To be honest, I don't want any - everything on the car works and I'm not going to risk any new update messing it up ...


One odd thing I noticed this time when I plugged my cheap ODB reader - SoC showed 87% but the car was showing 67% on screen ... ?

My 2023 ZS EV SR just did a thing!
Always charged to 100% daily at council 11kW charger, discharged daily to 10%.

Garage so do you trust them?

I wouldn't expect 100% from a brand new car, that's why I said it's unusual... Read some threads about ODB 2 reader (cheap Bluetooth plug-in) and how to measure it yourself. Quite easy and you can buy them on AliExpress or Temu for £3-£5

BUT - don't get obsessed about it, the car will serve you for years and years in any event. Long Range as far as I remember should be charged up to 80% and only when you really need it, to 100%.

Yes I only charge to 80% except twice a month when I do 175 trip down to Huddersfield and then 100% to go back also probably only 6 rapid charges in the 12 months.
