Question 1: Will this app (eventually) also work for iX3, iX, i4 , .....?

Queston 2: Will the app logo cause a copyright issue when you go live?

Feature request: In the charge graph (at least for DC charging), also plotting the battery side voltage+current+battery and coolant temperature as lines will provide insights into why charging powers alters over time.

@Orbit
these are good question :)

>Will this app (eventually) also work for iX3, iX, i4 , .....?
Needs to be checked yet,
dont mind to support these.


About logo: it can change any time yet, logo offers are also welcome.

please consider 1024x1024 and other dimensions, see requirements here

Can you try to press on (i) mark next to Charts
it is either view dimensions are not respected , for some reason
or you are in zoom mode already -> (i) will reset zoom to default.
There is no such mark that I can see. I also tried to zoom out fully manually. Zooming in/out seems to work, but still no labeling for me. I'll send you a video link by PM.

Feature request: In the charge graph (at least for DC charging), also plot the voltage+current+battery and coolant temperature as lines to provide insights into why charging powers alters over time. E.g. most 50 kW DC chargers will throttle on 125A, even if this is less than 50 kW at low voltages.

yeap, checking Chart framework...

Good proposal !

Two bugs (v1.0(10)):

As the start of a charging session, charging power is calculated before there is a value for AC phases, thus resulting in incorrect data. This value should not be calculated before all the dependencies (phases/V/A) have a valid sample. In attached graph, that leads to incorrect charge power for the first period.

What is labeled as "charging power", is really the power consumption from the charging cable, not necessarily going to charging. In below example. that is 10.74 kW (on a 22 kW charger, but car is apparently not demanding the full 16A). On the DC side, the power into the battery is 397.2 V * 21.7 A = 8.6 kW. There is some AC/DC loss here, but the big gap this time is mainly from having car preheating on, consuming around 1.5 kW.

I am really impressed how fast and easy the app is connecting to the Vgate ICar BLE OBD adapter without any setup and without the need to disable Wifi on the iPhone Bild
Attached an screenshot from a charging session with CCS at 30KW (shown on the display of the charger).
The app shows the exactly the same value

As some already requested:
A connection to the ABRP route planner would be great Bild

I suspect this is because I'm running phone in dark more, and thus the label text is white. If so, the bug is then that the graph background is set fixed to white, while it rather should be set to "background color". In the same way, the graph grid must be "text color" or "foreground color", not black.

@MaxD I'll retest in light mode next time I charge to see if that makes labels visible.

As you can see in my screenshot, there are correct labels and grids, and this was taken in „normal“ screen mode, (no dark-mode)

I just checked the same on my phone, also works fine there in light/default mode. So it's the graph colors that are not altered according to screen mode.
