Still collecting numbers?

Max. Det. 7.5% , Cell #2
Min. Det. 6.5% , Cell #25

Batt. tmp. 27 °C (and it is sommer here)

ODO close to 30'000 Kilometer

Drive/SOC habitats:
I do not force the car really and drive in ECO mod 99% of the time
Usually exept for balanceing once a moth or so do not charge over 80% (more in winter when I need 100% for the roundtrip (selden).
I leave the car parked never with any SOC below 20% (usually 25%).
Charge a lot 50kW DC and drive it often to arround 13% SOC (in winter sometimes even to arround 8%) direct to the 50kW DC station and load up to arround 75% usually.
I drive and charge so my battery is not getting warmer then 40°C.
KIA Soul EV with vented seats and Chademo
Until July 2015 i-MiEV 13'500km

Yes. I'm still collecting the numbers. Thanks for posting them.
All of the cars participating in the collection of data on this thread are doing well. No major battery problems.
For instance my car is over 2 years old, has driven nearly 40,000km and is still at SOH = 100%. I am nearing the end of the 10% buffer, so I expect to begin to see a small decrease in range over the next year.

But there are now plenty of stories of massively decreased range, battery failure and / or severe battery degradation leading to battery replacement on other threads. We have very little data on these failed cars, so we can't really say why.

An example is here - Evie zeroed out at 53 miles and UPDATE!! Evie's battery replacement complete!
