Battery SOH

2nd service,
SOH 93% on 27K, sound about normal?

Hi, do you mainly charge at home or on Rapids and how often do you do a battery balance?

That's the same as mine after 2nd service, with only about 8600 miles. SOH calculation with LFP packs is largely time-based for the first couple of years - expect it to level off going forward. e.g. maybe 92% next service.

Not sure LFP packs balance the same? but I do 100% charge it most of the time (3-4 times a week) as I have cheap night time rate. Only do 10-20 rapid charges a year.

Bought myself new diag tools, old stopped around 2018. An Autel for ref and it’s reporting 93.something on first gen SE with 13k miles.

It has had about a 60% charge and 10 mins on rapids its whole life.

As it happens I checked mine today using my OBD dongle and Car Scanner ... 91.08% was the result.

Mine had its second service yesterday, 97% at 15,800 miles.

Mine had second service a month ago 98% 17900 miles

My Trophy had its 3rd service last month 98% at 33000 miles. Mind you, they gave me a scare by mistakenly writing 78% and then correcting it by writing 98 over it! Must check with car scanner...

As discussed in a previous thread; the value you get is not totally accurate. It's a time based value, not actual degradation.

In any case, should be fine.

Anecdotal info ... as I was driving home last night, I was almost home and the Acc Total counter reset (at 100 hours). Before the reset I had 57 miles remaining on the GoM; after the reset this rose to 64, then 65 and then 66 miles (with 47% SoC). I plugged in last night and charged to 100% ... this morning the app showed 203 miles range, and 193 (ish) when I got in the car with HVAC on.

203 miles vs the WLTP of 218 would suggest a SoH of 93% (using the methodology mentioned earlier/elsewhere) ... Car Scanner showed 91.08%.
