SOH 100% and poor range

One possibility is that the cells need balancing, which is done when you charge to 100%. What does the cell voltage readout look like, particularly the difference between highest and lowest?

Oh well, another theory bites the dust. I don't suppose KIA will show much interest with the SoH so high. The only thing I can think of is to keep records to compare percentage of run consumed (%start - %end) and the m/kWh over the run, with the GoM (miles at start - miles at end). Multiply m/kWh by (%start - %end)x28.8(the nominal capacity)x93.8( the current SoH) and compare to GoM (miles at start - miles at end) and to difference in speedo mileages. I hope this will point to a discrepancy either in the GoM values or the nominal capacity.
As an aside, SoC (precise) is just a label assigned by the SoulEV Spy author. He stated he did not know what the parameter was, so it is best ignored.

Ran it 113 miles, to 11% battery, @ 4.5 miles / Kwh. Charging it to full took just under 29 Kwh - I figure an energy conversion / transfer loss of maybe 15% in there.
Range is showing 96 this morning
So we don't have much to complain about regarding the replacement battery and real world range, but a pity the GOM hasn't reset to something more accurate.

Thank you uspurs for that latest update. Real world range is what matters most. I ran down my car from 100 to 1 %, 52 miles with the ac on (4 miles kw/h 
). Fully charged it with my juicebox, according to the app it took 13 Kwh. I’m going to take it back in to try and get it replaced.

The cynic in me thinks that Kia know the SOH isn't a reliable measure of battery health, but they're content to continue using it.Alex81 said:Thank you uspurs for that latest update.

So, took in my car, 50.3 state of health. They ordered a replacement, just picked it up. In Cerritos, California. Whole process took under two weeks. For parts it just says
37510-E4202R And it clearly states re-manufactured. Not sure what cells they are. Guess-o-meter at under 100 miles for a full charge.

Well, I did not know that about the + trim, which we do have - thank you!ksoul2084 said:Alex81 said:
Yes. They sold the KIA Soul "EV" and "EV+" trims, and only the "+" trim has the built in battery heater / heat pump circuit.
My Canadian "EV Luxury" version has it, as we need it up here.
Range on the GOM is now down to 94. Ran it down to 13% (106 miles) and the GOM was at 9

Clarification, it looks like both the EV, and EV+ models have the heat pump, the EV-e version did not. But that is actually separate from the battery heater itself, which is electronic. My recollection is that the heater was only installed in cars going to colder climates (aka not Cali), but I can't find a written reference for that now.

So you're seeing approx. 115 miles of range. That sounds about right for this model, maybe better than the official EPA rating.

I would say a little more than that, as I believe the pack is now 28.8 - based on other posts. That said, we remain nervous of testing the range too much further - about the only gauge we have confidence in is the odo on this car.ksoul2084 said:uspurs said:Well, I did not know that about the + trim, which we do have - thank you!ksoul2084 said:Yes.

We'll see where we are, range and battery wise, after the winter, but I suspect we'll be looking to get into a used Kona or Niro EV at some point.
I am curious about what people are seeing Kia offer in terms of 'goodwill' for all the aggravation with these batteries on the gen 1.
