Soh after 20k miles

[Andy L]

For anybody who worries about battery degradation I don't think there is any need. Mostly home charged with the occasional rapid when needed.

How old is the car?

2022 trophy LR

@Andy L Very similar to our Trophy LR.
Just over 2 years old now, covered about 16,000 miles and the traction battery SOH is reporting 99%.
No D/C or A/C public charging conducted, all charging requirements have been satisfied by utilising a cheap off peak electricity, supplied by our home wall box.

You can request that the dealer provides you with a traction battery status report, at the time of its next service.
Or purchase an OBD scanner that has the ability to interrogate the battery, this can be displayed from an App on your smart phone or tablet.
I don’t have a OBD scanner so I am unable to recommend one for the Gen2 model.
I am sure one of the other members can offer help with regards to this .

Thanks Andy - I am running IOS ( IPhone 14 ) and the eBay link is great .
But if I search for the EZS App in the Apple Istore, it fail to show anything ?.
Maybe I am not using the correct naming ?.
Can you please help.

Unfortunately, the eZS app is only available for Android.

Edit: But, SoH can be obtained from several other apps. I'd start with the one called Car Scanner.

purchase an OBD scanner that has the ability to ingratiate the battery.....

Is this where the App sends messages to the car declaring undying love?

 

[chris69]

Mine’s a gen 1 and the SOH is 88.6% after 26,000 miles. Also mostly home charged.

I was going to blame “predicted text” but I think the problem is more to do with what is behind the phone.
Plus using my old glasses !.

I don't know remotely enough about batteries but from what I heard so far, 88.6% seems low? How old is the car and have you ever run that slow charge from 10% to 100% ?

It’s 4 years old and gets balanced every 4-6 weeks. Local dealer reckons it’s as expected after 4 years, but it seems to have dropped fairly quickly since October when it was 92%.

Are you reading the SOH yourself via a OBD reader, or is this SOH being provided by the MG dealer, may I ask ??.

Both.

 

[Tim Green]

I wonder how the SOH calculation is made?
Also, is it dependent on charge status at the time?
Also, winter/summer?
Or is it just another way to worry oneself?

There are apparently a few different models to calculate it. No idea what system MG are using, although there was some evidence that MG were sort of 'faking' it in LFP version of the car with a linear regular reduction, until it got properly reset at service time.

These are the principles:

 

[BingBong]

Do you charge up to 100% or 80%?

80 most of the time.
