How do you actually check the battery soh ?

Dealer only with the MG4 (unless you can find it via the Home Automation route? See posts by @wattmatters). Other models might be able to get the info via OBD2/11.

Cleevely EV use some form of "software that goes to the cloud" : 5:30 mins in

The Home Assistant integration I have doesn't report SOH. I don't know if that's a limitation of the integration or of the information available via the SAIC API.

But my OBD reader does show a SOH value:

Since it is reporting a 100% SOH value, I guess I'll have to wait to see if/when it drops below that to see what it says and what precision level it reports.

100% SOH at 12 months mark on 12000 miles

Why the 2 (differing) SoC values? (SoC and SOC)

I think one is the "reported" SoC (what you see in the car) and the other is the actual SoC taking the reserved headroom/basement into account.

SOH mis-reporting will probably be (one of) the EV scandals in 10 years like diesel emissions - 95% SOH but only goes 50 miles
