Read Battery Capacity Yourself (Autel AP200 Breakthrough)

Actually they arrived since 10/2020 and even that
The grey one arrived since 8/2020
And distance since dtc clear maybe also a false indicator because sometimes we clear the stored data for many reasons but I'll keep an eye over the grey one after another 2 cycles of charging
Note that i didn't need to use level 2 chargers at all

 

I think the big question is whether the rate of decline will flatten at some point, like we see with Tesla. This should happen around 20-30k miles.

Hi, I've been away for a while, but it seems like my issue with the 55Ah result really has to do with the calibration resetting due to some 12 volt system issue. My reading has not changed but I am only around 600km of driving. Not the 1k miles someone else posted here to get a reading changing from 55Ah.

So I do want to reiterate now the dangers in Honda dealers not knowing about the default value being 55Ah.

a) if you do get a PDI value, it is not accurate and does not reflect the health of the battery (It could have been sitting depleted on a hot lot for a long time before purchase and PDI), so in this regard Honda forgetting to get PDI values is a good thing if you got them to give you a reading after you've driving the car for a while.

b) if you want to make a warranty claim on the battery, DO NOT let them reset the 12 volt system, which is in their procedure for diagnosing charging and power system problems. i.e. don't go in asking that you have power issues or range issues as when I had GoM range prediction problems they disconnected the 12 volt line on me as part of their procedure.

 

That's interesting. I use the Canadian powertrain report, but I have everything from the US report. Perhaps the dangers of the beta. The app experience is inconsistent.

 

@MrFixit - You were looking for a volunteer to see if the Battery Capacity of the Clarity might be reset it to a value around the initial range of 55Ah when the battery is disconnected. I removed power from the 12v battery for a couple of hours today, while installing cable for a Dash Cam, and after I finished, I tried to run a test on the Audel AP200. It failed to connect, unfortunately, telling me that the main app or the Diag-Asia app was not at the level necessary to run it. I haven't resolved that new problem yet, but I was instead able to run a quick test using the Vgate adapter.

It indicated that the Battery Capacity was at 50.14Ah, a bit below my most recent results of 50.3 Ah on 3/17/21 and 3/23/21, so it appears that it didn't reset the value. I'll keep testing frequently, and report if anything dramatic occurs with Battery Capacity.

 

Yes, it is a mystery how cars with 17k miles could possibly still have something close to the 55 mAh readings, unless they are driving 100% EV, but even then, there would be periodic EV activity. If the results are real, we have to figure out their secret - fast.

 

I suddenly can't seem to make any progress using the Autel app, which had worked reliably through my last use on 3/25/21. I can log into it, I get a VCI Connect, it shows as Bound to my account, and paired via Bluetooth, but when I select Diagnostics and Honda (which shows the V2.01.54, Expiry infinite), it gives me a message that the version information doesn't match, and to go to Google Play to obtain and install the latest version.

When I select OK, it just takes me to Diag-Asia in Google Play, with the option to Uninstall or Open, with no option to update the version. As I mentioned above, the Vgate adapter works fine. Has anyone else been through this kind of problem with the Autel AP200?

 

The Good News/Bad News thing. I'm not alone, but there is no fix in sight. Fingers-crossed that Autel might come through. Has there been any discussion of the problem in the forum? It might help to isolate the problem, if it does only affect some Android users.

 

I have a a very fast wifi network at my house. It is both 2.5gHz and 5gHz and all the channels are available. I checked the connection speed while the Autel download was taking place and the link was always in excess of 100 Mbps. For example, the Google play downloads are quite fast and I can easily stream 2k video and cable tv on the tablet. And, my work area is just 10' from the wifi router. BTW, the wifi connected laptops have link speeds in excess of 800 Mbps (near gigabit speed)

I think that any connection speed and other issues are with the Autel server. I also think that when Autel checked earlier today to see if my AP200 device serial number was in the beta access database, something may have been reset to again allow access to the beta diagnostic software.

One check is to see if the person who has the AP200 with serial number ending in 31 can now download the beta again, too.

I did report the error through the play store on Saturday, 3 April. Who knows if that helped. But uninstalling and reinstalling removed that version error message for me, and I still see the beta version available on the store in the app.

 

I guess our real hope is that there is some variable at our end, Android Phone Model, OS level, whatever that is causing or contributing to the problem. I just tried it again on my current phone: Pixel 4a 5g, on Android 11 OS, w. March, or April Security Updates. It failed again, with the version mismatch message, just as it did yesterday.

I then tried it using my old Pixel 2XL, on Android 10 OS. Yesterday, I couldn't get to the app to upgrade to the beta, but today, it was somehow ready to accommodate, and I upgraded to the beta with no problem, with no delays or slowness in transmission and installation of the beta to my phone. I was then able to successfully connect and generate reports.

I plan to go back and try the uninstall/reinstall of the app on the new phone tonight, using Android 11. I'll report back whether that works or not, but at least I may be able to count on the older phone, perhaps. No guarantees here. What works today, may not tomorrow, but it's really helpful to have our community for collecting data that might be problem solving.
