Re: Setting up Torque to show BMS data

Unfortunately it seems that only members can see pictures from elbilforum.no ...

Regarding strategies for 12V charging, one must keep in mind that lead-acid batteries in general have a resting voltage of 12.8V when fully charged, and should then not be held at 14V+ for prolonged times. When they are full, only a floating voltage (typically around 13.0-13.5V) should be applied. This is probably what we see in our cars.

But there may be tradeoffs done in the implementation, because the DCDC can't know exactly how much current goes into the battery (to my knowledge there is no current sensor on the 12V battery), and how much is drawn by the 12V loads.
On the other hand, most major loads are known to the system so they should be able to compute a reasonable value for the 12V current.

I have checked a lot of my saved logs from the nightly charging (2kW). There seems to be at least two strategies for charging the 12V battery. Most common is for the DCDC to start at 14.5V and go to float at 13.2V after one hour. Approximately once a week it starts at 14.5V and goes to 13.6V float after 3 hours. The voltage on the battery is then 13.0V and 13.4V respectively, due to 0.2V drop from DCDC output.

Elbil also bans all users from Asia. I have asked the admin twice for my IP to be unblocked but my request has been ignored.
To view the Norwegian Kia Soul EV forum I must use a VPN from Europe.

Hmmm, maybe I'l have to find a free share... Any special you can recommend ?

Not sure I agree to that :-)
As long as they use a regular start battery like petrol/diesel cars use the volt need to be higher but.... If they change to batteries used in solar panel system (fritidsbatteri) you will have a more powerful battery, not sure why there is a start battery in the car because you don't need the capability of heavy Amp drain during start like a starter engine use

I think it know, in my 2018 there is a small junction box on the negative battery connector with two wires and to me it looks like a shunt measuring power in/out of the battery


I have tried to find the workshop manual for this care for months but no luck, I know Kia has the Pay site but i was hoping to find it as a pdf somewhere, would be easier to identify how the cars is connected together

The charge curve looks normal, 3h at 14.5V followed by 13.6V float, although in my car the Amps level out at 4A, which seems as a reasonable load by the ECU:s and the OBC+LDC, so not much current goes into the 12V bat.

And yes, you are perfectly correct about the sensor, it's a current shunt on the minus. According to the workshop manual it is connected to the LDC but the value is still to be found on the CAN bus..

... if any can find the teaspon and help that would be great because I am in deap water when it comes to Hex ande Desimal...

If someone can explain this to me that would been great

From the soulspy log I have this:

>21 05
21 05
7EC 10 2D 61 05 FF FF FF FF
7EC 21 C3 C3 C3 C3 C3 02 02
7EC 22 01 00 00 00 00 11 39
7EC 23 23 28 00 01 50 02 01
7EC 24 00 00 00 00 00 00 A7
7EC 25 00 00 C3 C4 00 00 00
7EC 26 00 00 00 00 00 00 00

I know that this is the last batteryCell 97-100 (+ 101) and I know I can tranlate C3 to 195 and from the Torque CSV file I can see that this value need to be devided with 50 to get the value 3,9volt

000_Cell Voltage 97,Cell 97,2105,e/50,2.80,4.20,V,7E4

ok but how do you identify e (where comes e from ) I have just guessed me to that it is in the second line comparing to all the other 96 cell but wit was just a guess and in the Torque line what is 7E4

If it's to complicated to describe, it's ok I was just hoping to learn something new on the last day of the year :-)

Hi all, it's been a while!

I added some new codes in Extra Gauges to show only positive numbers while charging on a CHAdeMO charger (and 0 otherwise). It's easier to read for everybody instead of negative numbers.

It looks like this:

Is it normal that you see strange values in the Torque log like this ?

Hi, two questions

How can I get Torque to show the distance on my trips

and is it possibe to show the odometer in Torque ?

I think the following files need a new version for the 2018 Kia with 30kWh battery if we agree to 101 BatCell.

Kia_Soul_EV_BMS_data.csv

The RED marked values is 96 in the original files

Kia_Soul_EV_VIN_data.csv
005_Year, Year, 0902, K+1945, 2014, 2035, , 7E2

This one give me a 2019 model

Edit!
There might be more

004_CALC SOH Battery in kWh,SOH in kWh,2101,27+val{004_CALC Lost of SOH},0.00,31.00,kWh,7E2

Do the red 27 need to be adjusted to 30 ?
