Read Battery Capacity Yourself (Autel AP200 Breakthrough)

[MrFixit]

That is worrisome for a Clarity with so few miles and charge cycles

I do not necessarily agree with your assessment, but this is exactly why we are going through this process (to learn about what to expect from this experimental vehicle).

I assume you have seen the spreadsheet that @Danks has been building? I would encourage you to enter your data:
https://docs.google.com/spreadsheet...OQIpT_YiGp9N-vnBOiSz96C2I/edit#gid=1710145002

There are two entry pages - The Vehicle Data, and the Battery Capacity Data.

A variety of results are available... If you look at this page, you can gauge where your vehicle will fall:

To me, a 2018 with 8K miles and ~51 Ah does not seem particularly out of character...

It just hit me that this is likely the common link... When these vehicles make the trip across the ocean, they undoubtedly have their 12V battery disconnected for an extended period of time. When did they arrive?

There is a parameter that you can read with the AP200 that contains the "Distance Traveled Since Battery Connected". It is not located in the Electric Powertrain, but rather in the "AT" Control Module. It would be interesting to know this value for the vehicles with anomalous capacity readings.

I think it is becoming clear that 12V battery disconnects result in loosing the capacity calibration. What remains unclear are the necessary conditions to get it back.

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.

I looked at my Powertrain report and did not find OBC AC... items. Ran the report again and no luck, was not there. Finally, I found USA Powertrain report differt from Canada Powertrain report. The canadian version has 196 items vs 409 for USA. I compared the two report in this file.

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.

Let me warn everyone... The AP200 is very sluggish and it is quite possible that these comments about the Canadian setting giving only partial results are incorrect.

Make sure when you enter the Live Data mode that you wait for a while before generating a report. It takes a good while to populate everything. I usually scroll up and down through the screens, and make sure that everything seems to be populated and 'stable' before hitting the report button.

Perhaps @ptcr00 could revisit this and see if my theory is correct since he reported the 'partial' result...

 

[vicw]

Agreed...
It sounds to me like you just volunteered to do this experiment for us !!

@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.

 

[MrFixit]

Sounds good. Thanks for reporting on this.
Although it was the only theory on the table, it would have been surprising to find that a loss of 12V could cause a reset.

Now, we need another theory for this. There are 3 or 4 vehicles that seem to have readings that are just too good to be true.

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?

 

[MrFixit]

Yes, there are some others with this problem too.
I have an inquiry in to Autel but they have been unresponsive.

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.

 

[MrFixit]

OK everyone...

I am aware that some are having trouble with this. There are examples of those who just cannot "see" the Beta version in spite of having their serial numbers activated. There are also a few who seem to have lost access and are presented with a message like this:

This message implies that the App (either MaxiAP200 and/or Diag-asia) needs to be updated / reinstalled. Attempts to do this have failed.
I just got a virtually useless response from Autel which I will convey here:

-------------------------------- Response from Autel ----------------------------------------
You do not need to add for all user's about this beta version.
Beta version is for beta user, not for everyone, if with many users, I am worrying if there is problem because we did not do lots of test on it.
I put request to team to release beta version to CAP*********95 , but because of public holiday in China, probably a little bit late to get response.

CAP********16, and CAP*********31 I checked again, the software in server is normal.
Probably the network is not responsed to user's phone, user can try to uninstall the APP then download again

This user also sent to me about this page, this is not a problem, please just follow the instruction to download the latest verison.
-----------------------------------------------------------------------------------------------------------

I have informed them that all of us ARE Beta users, and we totally understand that a Beta version may not be fully tested, and/or have bugs. Our issue is not with the Beta itself, but, rather, with inconsistent access to the Beta.

We are going to have to try and support ourselves as best we can. Autel almost always tells us that there is no problem at their end. There may be something that we are overlooking at our end with this. To this end, let's collaborate among ourselves right here in order to try and understand what is happening. After all, it was OUR users who determined that Android 64 was a requirement that we were unaware of....

If you have one of these issues, or some other problem with this Beta (or if you have overcome something like this), please speak up here, and we can all try and assist in lieu of true support from Autel !!!

 

[MrFixit]

@leop just informed me of his experience earlier today...
He had lost 2.01.54 and was unable to get it back until this morning...

Here is his comment:
"I was immediately greeted with the beta (2.01.54) downloading and then installing (after a long, ~ 30 minute download time). I have not been able to check that the app runs as the Clarity will not be back until this evening"

I would like to propose a possibility. The fact that he had this very long download implies that he may have a poor internet connection. My connection is poor when I am in the garage. Yes, it could be Autel's end too, but I would suggest to anyone who is having this kind of trouble, to move closer to their router. I have found that the Bluetooth connection to the AP200 is pretty robust and you can move away from the vehicle and closer to your router, maintaining both connections. maybe some of these problems could be solvable by intentionally moving toward a better WiFi signal. Relying on Cellular data could be problematic too because these are pretty large downloads and cell data is rarely as reliable as WiFi.

 

[leop]

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.

[MrFixit]

I am not trying to second-guess anyone here. Since we almost never get anything useful from Autel while trying to solve these problems, I just felt it was important to share ideas and possible solutions. Internet connectivity issues are very common. It may not have been the issue in your case. I'm extremely doubtful that my inquiry to Autel (given his typical response) actually triggered any action on their part. In any event, let's continue to collaborate in this thread. There are quite likely some members having trouble that we can assist by using the knowledge we have collectively gained without beating on the Autel "dead horse".

If there was some action earlier today that 'triggered' something at the Autel end, then the others may be resolved too... Please report in if you were having trouble and let us know if the trouble persists !

 

[leop]

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.

 

[vicw]

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.

@Mattematical -
If you see the Beta version in the store, that's what you want... Are you saying that you are working now?
