My stats as taken today, roughly 12,500 km
Leafer said:I have finally made some time to gather my deterioration numbers. Not good :-(
I used ZuinigeRijder's spreadsheet (b.t.w. an obvious error I noticed in cell K25 ... I did not check the rest of the 01Feb2016 version of "KiaSoulEV2101_2105.xls" for other errors) and plugged in my data from alOBD Terminal.

And you can paste the values in the spreadsheet in this post:

I did made a spreadsheet, so people can copy/paste the hex data to the spreadsheet and then the computed values are shown.

Leafer said:Thank you ZuinigeRijder and JejuSoul.
This Deterioration issue has been bothering me, so I have taken some time out to gather more info, in particular now that I have a working OBD2 reader. I also purchased TorquePro.
I have TURTLED the car twice in the past three days in order to effect Battery Calibration. Below is the "story" ... but the take-away is ...the deterioration values still disappoint me.
I have a feeling that the dealer in its original 1-year-9,225km ownership let the car sit at 100% for extended periods of time, but I have no way of verifying this. 9,225km on a demonstrator also is quite a few "miles", and I am sure many of those miles were "hard" driving.
Before I present the data, has anyone figured out how to get SOH (without going to the dealer) ?

ZuinigeRijder said:That is also that I stated that the battery deterioration should be compared in relation to CED instead of actual km or miles driven.
How more economic you drive, how longer the batteries will last.

Good suggestion I will keep track of CED & CEC in future data postings ...

Hello Elmil:Elmil said:Leefer (sorry, just can't stand the forum commercial hijacks), I guess you live in the US and suffer from higher temperatures than we do in the cool Scandinavia...
But I have also seen signs of dealers not understanding how to charge an EV. If they are lucky, they use a 20kW chademo and think it's fully charged when finished at 83%. But they might as well just connect the original EVSE over night and the car will be standing in the showroom for 3 weeks at 100% SOC before anyone calls for a test drive...
I am now at CED = 6880kWh discharged during 40727 km = 16.9kWh/100km average.
As it happens, I did a similar 100% -> 0% trip just a few weeks ago. Here's for a comparison:
..................
Probably the temperature is the main reason for higher deterioration, but on the other hand my values were at its worse at christmas last year, (11.2%/10.2%, 22610km, 3749kWh).
My feeling is that if you drive VERY gently and get most miles out of the used energy, the deterioration values will go down. So my interpretation is that the deterioration values are more connected to the DTE function than to the physical state of health of the battery.
I suspect the dealer used the KIA supplied charge cord (2.2kW).
Beware that the CED number also includes regenerated energy from braking.Elmil said:I am now at CED = 6880kWh discharged during 40727 km = 16.9kWh/100km average.
The above 3 sentences taken together appear to be in conflict with each other, either because a) you misspoke, or b) I do not understand how CED is computed. And/or c) there is a fundamental flaw in trying to compare the CED/Odometer with the Energy Consumption the car displays (your 12.5 number).JejuSoul said:Beware that the CED number also includes regenerated energy from braking.
My car is at CED = 4463kWh discharged during 21754 km = 20.5kWh/100km average.
But my real average is about 12.5kWh/100km because I recover a lot of energy using regen.
No need to be sorry. The way these counters work is not what you would initially expect.L eafer said:So ... sorry for being confused. Please let's explain (or point me to an earlier thread) about how CED & CEC are calculated, and how it relates to Energy Consumption displayed for each trip.
The answer was provided by goev the author of the Soul EV OVMS software a few days later,JejuSoul said:I do not fully understand the Cumulative Energy counters.
They do not seem to match what I put in or use. Here's an example.
On Nov 11th I did a lengthy test drive charging the car before and after.
I took readings at home, a 30 min drive from where I started and finished the 215km round-the-island-on-one-charge-trip.
Total driving for the day was 273km, which took 7.5 hours.
....The readings on the charging machines from the 3 charging sessions suggest I added 35kWh.
Using the reading on the car's display 8 km/kWh suggests I used 34kWh for the trip.
SOC at start = 56%, SOC at end = 62% which is why I charged more than I used.
The Cumulative Energy Charged data increased by 50kWh
The Cumulative Energy Discharged data increased by 48kWh
What is the reason for this disparity 35 / 34 contrasted with 50 / 48
goev said:Jejusoul, can recuperation be the cause of the differences you see in your numbers?
If your car produced 14-15kWh in recuperation during driving, this would add up:
Cumulative energy charged: 35 from charging + 15 from recuperation = 50kWh
Cumulative energy discharged: 34 actually used "from battery" + 15 of the recuperated energy = 49kWh.
This might also explain why the cumulative discharge/odometer is so high on my car: 21.62kWh/100km.
JejuSoul said:There are only 2 outliers. Elmil consumes less than everyone else. and SoulEV2016 consumes far more. ( 33.6 kWh/100km suggests a data error)
SoulEV2016 said:I drive fast and drain battery usually with 87km (31km use 1/3 of the gauge of the dash).
I only drive at 90km/h on highway when i must drive more than 100km per day (usually ... 2 days per month).
ON/OFF profil to resume. :twisted:
