I tried to connect today but it was stuck in "connecting". I switched to Bimmercode on the same device and it connected flawlessly. I'm using a basic ENET cable.
Will retry tomorrow with wifi so I can post the feedback via Testflight, as I can not do that in my parking garage.

Do we think they will make an Android version?

I would be very surprised if they don't. I would expect that most of the work is in the core code for interfacing and getting the data which is not mobile specific.

I suspect they wanted the app working well before they released it to a more discerning customer base.

After few days of comparing CarData and BimmerFlow, the battery capacity numbers are the same. BimmerFlow shows spread in the state of charge among cells. This correlates nicely with the overall capacity: smaller differences->higher battery capacity (Health) at ~1-2 % level. The spread in state of charge among cells correlates with time to condition before DC charging, outside temperature when charging on AC, time from driving to the time of reading. Bottom line: temperature differences between cells during charging or reading will affect single number representing battery pack capacity. Any chance to implement cell temperature reading?

Got the same, when I used my old vlinker mc+ BT it worked ( enet not working )

I’m not selling snake oil here. From the MY22/23 BMW i4 warranty booklet:
“Battery performance and durability, including high‑voltage lithium‑ion batteries, is temperature‑dependent. While battery capacity increases in higher temperatures, colder temperatures will lower the battery’s capacity.”

You can do your own research, but temperature absolutely, without any reasonable doubt, affects the capacity of most batteries, not just high voltage lithium-ion batteries.

I would just add to this that they talk about usable capacity. Total capacity is measured at nominal temperature.
If you run the car under 10% SoC when temperatures under 0°C. you will even get a message that when battery is cooled down after longer period parking, usable capacity will be decreased.

The BimmerCode team reached out to let us know that they have a TestFlight of their new Bimmerflow app for EVs available:

TestFlight - Apple

Using TestFlight is a great way to help developers test beta versions of their apps.

testflight.apple.com

Here are some screenshots to give you an idea where they are headed:

Will be glad to jump on Android beta program when available. It is exactly what I want...
Any chance to sniff on OBDII for PIDs?

Thanks, @phchecker17! I do not see temperature listed in the app, so hopefully they'll add it.

Temperature added, percentage of full charges and others.

Your car has lost 5 to 6 kWh from a nominal 81? 8 percent range loss or have we decided it’s not accurate? Honest question.

Wow this is perfect! Sadly it doesn't look like they fixed the ENET thing so I might need to get a wireless adapter after all. Love to test it out on my next trip and see the battery temperature with the preconditioning active.
Honestly I thought they already had all the values they could get in the app, I'm surprised they have that information too. Can't wait to see what else they will find and add to the app

Let me see if I can find out anything about the adapter issues some are having...

 

[phchecker17]

I ordered a wireless adapter so I will test it tomorrow and see if it works I can send back the cheap ENET cable I got so it's not really an issue.

If you're going to code your car, hang onto the ENET cable. It's faster and more reliable than any of the wireless ones. If it works at all, that is.

 

[phchecker17]

As I‘m on 8.5 I can‘t really code a lot, so all the coding is already done. I rather use it wirelessly on my phone but slower, than with cable on my iPad.

I've confirmed the team are looking into the connectivity issues.

If they need details, let me know how I can help.

Mine: 3ish weeks since collection, 600 miles total.

Congrats, looks like you won the battery lottery.

 

[phchecker17]

@ssh Should've listened to you. I sent back the ENET cable right before I tested the BT adapter and it takes like 5 minutes for every coding. Well, I'm still gonna keep it like that probably because I'm not gonna code anything else.

Now back to topic: everything worked with the BT adapter. Attached the results which in my opinion are awesome!
Battery is at 99,7% and some cells are even above 100%. That is with the battery at 5°C, which is around 41° in freedom units.
Can't wait to see the temperature rise when I first try preconditioning now

 

[phchecker17]

Today I had a longer trip where I wanted to gather some important data. Went all the way till 1km left in the battery:

And these are the results:

Safe to say that I just love this app, now it's got almost all information that would be needed, except for maybe details on cell level, like a "seat plan". Temperature, exact levels of charge left in the cells (9%!), and the battery pack data with the kWh left.

Congratulations Bimmerflow for this awesome app!

It is strange how 0,38kWh left usable energy equals to 9% SoC. 76KWh x 9% = 6,84kWh. At 9% SoC almost 7kWh energy should be left. 0,38kWh is far not 9% for sure. That energy is around 0,5% in line with the instrument cluster (1%).
