OVMS für den Soul

[^tom^]

Both numbers are the same. They are just two different ways to display them.

I have been thinking of calculating the last trips-average, but the trip is always 0, so there is a bug somewhere. When I get the correct trip calculation, I can easily calculate the AVG too. I can be very useful. Then we have Trip A, Trip B and the automatic Trip-counter in the OVMS

In this case the numbers are not the same:

21.87kWh*5.28km=115km (not 100km)

Yes, I edited my previous post.

Maybe was a transmitting problem or so....will check this evening again

[^tom^]

lot's of news...
Android app and v.041
Voltage and Amps accurate during Chademo loading but the letters are very small and I need almost my reading glasses
I have no clue what "PERFORMANCE" is
Time left for fully charge is not what the Chademo protokoll calculate (it is calculated by kW and empty capacity) but usefull
Mileage left is since V0.4, 1km or 2 km differenc

Then app commands:
AVG (something not right)
00:00:24 (what is this for)?
Average
22.44kWh/100km
5.28km/kWh

BATT:
00:01:02
Battery
386.1V 119.1A (this is a 50kW Chademo charger)
AC90.00kW (?)
AD90.00kW (?)
C4.04V#42 4.00V#81 (I think cell 81 has the lowest voltage with 4.00 Volt and cell 4 the higest with 4.04 Volt)
CC2442.8Ah 900.0kWh (for me I think this is the total of charged energie, BUT WITH all the energie you had back from recuperation too (charged your battery))
CD2480.9Ah 890.7kWh ( I have no idea)
OT317h
Det9.0%#48 7.6%#3 (the value is maybe by factor 10 to high for the highest and the lowest)

Good summary, ^Tom^

Performance is a name used by the Tesla Roadster for the fastest charger. Have to change the mobile-apps to change that name. Could have used Standard, Range or a third one I don't remember, so I thought Performance was best of those.

Time left for fully charge is pure calculation: kWh's left / charging power = time left. It IS most certainly wrong in most cases, but it seems to be only a few minutes off, so I think it is useful too

The timestamp in SMS' are added by the OVMS-framework. I believe it is possible to disable it, but not sure how.

AC is the available charge. I guess the car can take 90kW from a charger? This number differs depending how full the battery is and maybe how cold it is.
AD is the available discharge. The engine can take 80kW, so we have 10kW for the rest of the stuff. I haven't studied these numbers.

You are correct about the cell-voltages. Also about the CC I believe, which is Cumulated Charge.

CD is Cumulated Discharge, so it is the energy taken from the battery in total. This is the number used, together with odometer to calculate the avarage power consumtion in AVG-sms.

The detoriate values I sure hope are 10 times to high I have no idea how they calculate this.

I have a new version ready soon, with SMS-notification when charging starts, ChaDeMo charging recognized properly and correct AVG-calculations. I've added trip in AVG, with power consumption for the last trip too, but there is something odd with those numbers at the moment. C18 is not the best compiler I've used, so getting the number right is not straight forward. At least not for a guy that usually program high level stuff in C# and Java

I just can hardly read what is written there (and not very usefull?)

I calculate 1% per minute with a 20kW Chademo and at home I get 7% per hours
So maybe more usefull for 6.6kW Typ2, but that the car is telling me.

Very interesting, so I have only 1.5% lost of energie in my battery.

Maybe you can find also total charged Typ1 port and total charged Chademo port.
Then we will know exactly how much energie we get back during driving.

AC is maximum 62kW (so say KIA)





Please do not forget bigger letters for the voltage and the current during loading! Thanks!

Add 32 to feature #14 to deactivate the SMS timestamp.

I've had the same problems with C18 and have written some general hints on this, see section "Architecture and Tool Hints" in the "OVMS_Development" document.

^Tom^, I'm not sure if I can remove the Performance-text from the OVMS-box.

When it comes to the time left calculation, I need to do some changes for the ChaDeMo. The charging will stop when the BMS SOC is 80%, so I need to calculate for that instead of 100%. That will be good enough for a first version, I think.

I don't know if we have the total Type 1- and total ChaDeMo-charge values anywhere, but I agree that it would have been nice to know how much energy is recuperated

What do you mean when you say AC is maximum 62kW? The Kia Soul can charge almost 90kW. The first 120kW charger here in Norway was demonstrated with Kia Soul, so it can definitively charge with more than 62kW

Dexter, thanks for the tips! I will check that out again. I remember I read it while waiting for the hardware, but I obviously forgot about it again

[^tom^]

The Soul EV at Chademo goes up to 83% and with a restart to 93%.
The maximal current you can load the 30kWh battery is 62kW (even if you have a 300kW Chademo charger) and this is why you are only about 2,3,4 or maximum 8 minutes (0% to 80%) faster with the 100kW then with the 50kW charger.

Hm... Where did you get that data from?

I'm not sure what to believe, but this article clearly shows a Kia Soul charging at 69.1kW:
http://arcticroads.com/nyheter/opens-12 ... he-public/
They have limited the ChaDeMo-charging to 70kWh as that is the maximum for the standard, but can open up for more.

The battery can't handle maximum power all the time, so it will slow down when it get fuller, but I think maybe it is the ChaDeMo standard that is the bottleneck here and not the car itself. 90kW charging might at least be possible while recuperating. Could have been fun to log a proper charging session and also see how much charge we can get while breaking
