@MrFixit has put together a page on GitHub that addresses the main topic of this thread and may provide answers quicker: Honda Clarity Plug-In Hybrid Battery Capacity Read
*** Just a friendly reminder *** If you haven't read your HV Battery Capacity for a while, now is a good time to get a new reading and share it with the group !! When you have your reading, here is a Link to the Shared Spreadsheet. I also want to introduce a new analysis feature that is now available: On the introduction page of the Shared Spreadsheet, you will find the list of analyses on the right just as before. There is a new entry on this list (highlighted in RED). This is a very nice statistical visualization which @Thomas Clauser has provided. We now have enough data to show a nice trend which illustrates the expected battery performance very well. There are 2 pages in this new analysis (choose the 1st or 2nd page at the bottom). On the second page, you can show views of all the measured data for one or more users (use the ''Name, DriverCar#" on the top right of Page 2 to filter just the users of interest). You can 'clear' this selection to choose all users, but then the graphs become too cluttered to interpret well. Please feel free to provide any thoughts / feedback on this new analysis. @Thomas Clauser is an excellent resource and did a great job getting this new visualization going. Thanks to everyone for their help with characterizing the Clarity HV Battery performance. We already have an incredible data set, and it will only get even better over time. Your participation is greatly appreciated by all !!
Happy New Year [again], and thanks to everyone for their interest in helping to characterize the HV battery longevity of this great vehicle !! Thanks to all, our data accumulation effort has been phenomenal! Don't forget to check out the results of this ongoing effort by examining the shared spreadsheet. This year, A forum member who is very talented in statistical analysis has contributed a new graphical analysis viewpoint. There is a link to this from the shared spreadsheet, or you can get to it directly here: Thanks to Thomas Clauser ! Statistical Analysis Here Here is a link to the Shared Spreadsheet. The Introduction Page has instructions and links to data entry and all of the graphical results: Shared Spreadsheet Here If you are already a participant, but haven't done a measurement for a while, the start of 2023 is a great time to pull out the OBD tool and add a fresh new reading to the data set !!! Thanks again for all of the interest
Is there any way to get this spreadsheet pinned to the top of the forum? Personally, I have to keep searching for it!
@Domenick - What do you think? Would this warrant a position at the top of the forum in some fashion? Instructions as to how to read battery capacity: https://github.com/clarity-phev/Battery-Capacity-Read Battery Capacity Spreadshet: https://docs.google.com/spreadsheets/d/1LHtqVuPzHUDXmX1jiHOQIpT_YiGp9N-vnBOiSz96C2I/edit#gid=1710145002 Statistical Analysis of Spreadsheet Data: https://app.powerbi.com/view?r=eyJrIjoiZmVjMzJmZmEtMjI5NS00NGMzLWI4OGYtMDllZTRhNTEzZjE4IiwidCI6Ijk1YzY2MTczLWVkZjktNDI2Ny1iZjI0LTg2MjYxNmQ5YjY4MSIsImMiOjF9&pageName=ReportSection722ff76810b59b8797b9
If the first post in this thread has the info and links people need, then pinning it may be a good solution.
That did work for me, but I think it would be really useful for anyone coming to this site in general. From the replies I saw, it sounds like something might be in play!
I have no OBD device to read the capacity, but I know that it takes 12 kWh to charge it. How much is it in ah?
Assuming a new car will take 13.5 kWh to charge and new battery is at 55 Ah, then 12/13.5 *55 = 48.9 Ah. Someone may adjust my 13.5 kWh assumption for a new Clarity, but that's about what I remember....
