Hi ZuinigeRijder, welcome to the forum. I too have a Konnwei KW902. There is a copy of Torque Pro on the CD that comes with it. I have posted the commands needed to read the battery data with Torque Pro. It saves time converting all the data from hex.
ZuinigeRijder wrote:So it looks like the deterioration is already 11% with 18709 km driven. How does this compare with others?
We don't have much data (12 cars), but these values are in the same range as all the others (except 1 car in Switzerland). For example one car in Sweden driven 22160 km has max det 11.2%, min det 10.2%. We don't know how these values relate to actual deterioration in range because no-one has measured any yet. Posting the entire hex data is useful here because we may find a value for SOH (state of health) that has been zero in all previous datasets. There is a discussion of battery ageing in this thread viewtopic.php?f=6&t=434


I did made a spreadsheet, so people can copy/paste the hex data to the spreadsheet and then the computed values are shown.
You can download the spreadsheet here: https://dl.dropboxusercontent.com/u/35461579/KiaSoulEV/KiaSoulEV2101_2105.xls

Interesting enough, the State of Charge of Battery(BMS) is 55% (in 2101) and SOC Display is 57% (in 2105). 57% was shown on my display. (Max Deterioration is 11.6)
I also looked into the link and copied/pasted the hex data of Elmil in the spreadsheet. It showed State of Charge of Battery(BMS) 87% and SOC Display 91.5% (Max Deterioration is 9.8)
Same for Alex: State of Charge of Battery(BMS) 84% and SOC Display 88% (Max Deterioration is 8.3)
Same for Tyrel: State of Charge of Battery(BMS) 26.5% and SOC Display 26.5% (Max Deterioration is 0)

Would this relate to State of Health?

Yes. Elmil was collecting this data. See his post dated Fri Nov 13, 2015 12:42 pm at the
Battery Ageing Model thread viewtopic.php?f=6&t=434. Will be interesting to see if his later data shows a useful trend.
I am still expecting a value for SOH to be found because the system needs that value at all times to create the Distance To Empty (aka GOM) reading.

And thanks for linking your Excel spreadsheet.

It was one of the first demo Kia Soul EV cars on the market in the Netherlands (2014-08-26). I do not have any clue how the car was driven the first year and how the charging behavior has been.

As you know I have bought more or less the same kind of car as you. I have driven a bit more though. My odometer says 22038 today.

I also have a Konwei OBD dongle. At last I have found some time to get a few readings. This is what I got yesterday (when the car was charged and plugged in):

Note that Excel likes to help you with numbers. So when you enter "09" in a field it will change this to "9". This is sometimes helpful, but mostly annoying. It will also screw up a formula like "=HEX2DEC(B10&C10&D10&E10)" which is used for the Cumulative Operating Time. Suppose you have values as "00", "57", "09" and "AD" then Excel will convert "0579AD" which is way lower than "005709AD" because of the missing 0 before the 9.

Even so I still have a few odd values. For example yesterday it gave a battery current of 65533,00 Ah (hex values "FF" and FD").

The two bytes for battery current are signed. So hex 0001 is +1 and hex FFFF is -1. The unit should be A not Ah. All the temperature values from the BMS are also signed bytes.

So it should read -3 A? That makes sense. The climate control was starting to work and in fact the car displayed the "charging will take longer because the climate control is on" warning. It says something like that, I don't know the exact message by heart.

I changed the spreadsheet so it uses signed bytes and also doesn't lose characters when a conversion from Hex to Dec is done.

Can I send it to you so you can update the file?

I did update the spreadsheet with the fixes above. Thanks JeroenE.

JeroenE: Thanks for posting your data. The deterioration shown by the BMS counters is very similar to all the other users. And like them I don't think you have any deterioration in range at all.

To calculate a rough value for your usable battery capacity.
We see that you drove for about an hour and used 77% of the usable capacity.
The Cumulative Energy Charged counter increased by 0.3kWh. This is recuperated energy. We must subtract this from total energy used.
The Cumulative Energy Discharged less the recuperated energy increased by 20.8 kWh.
Hence your usable capacity is 20.8/0.77 = 27.0kWh

I still have the same range as I had 4 months ago. However, the range of this car is less than the demo car I drove.

We see that you drove for about an hour and used 77% of the usable capacity.

That's right.

The Cumulative Energy Charged counter increased by 0.3kWh. This is recuperated energy. We must subtract this from total energy used.

Is that normal? I didn't brake very much and it would be around 1.5 km range (when you calculate with 5 km per kWh or 20 kWh per 100 km). So that seems OK, I guess.

The Cumulative Energy Discharged less the recuperated energy increased by 20.8 kWh.

Right, the car had charged 22.89 kWh in the afternoon according to the kWh-meter of the grid. But the pre-heat was on. It didn't heat that much though. It was -again- reset back to 15 degrees which is kind of annoying.

Another annoying thing is that the dongle does not seem to work anymore. The red power light turns on, but the blue BT light doesn't. Pressing the button doesn't help :(

I had this too, after reboot/restarting my phone I could make a bluetooth connection again. So it is possibly more related to the phone/Torque Pro.
