My Kona is at Hyundai for the Battery update...

Hello @Wildeyed ,

Just for completeness here's the TSB you asked about.

Thanks. Very interesting...and exhausting! Battery replacement is a pretty big deal.

 

And how did the guy actually manage to learn that? Are dealer techs where he
is substantially less cagey than in the US?

@hobbit ,

Are you asking me that question? If so I'm in the UK and trying to get anything out of HMUK is near impossible, and even our UK dealers aren't informed about why they're doing some of the service campaigns!

I love Americans, though, because your agencies force businesses's to be far more open, and a quick look at the link I posted shows that this TSB was posted on the NHTSA.gov web site.

Nope, he just actually trialed through the 4 digit permutations, 0001, 0002, etc

 

You could be the first to provide a graph as well, kW by SoC. Log the parameters in Torque Pro and graph in Excel. I gather it's fair to assume that the battery temp at start of charging will be over 25°C.

 

From the home screen, lower right - select "Graphing" . I have never used it however, so I can't say much more than this.

 

Well, even manual graphing gets the job done, so it's no big deal. Best to graph power by SoC rather than time.

In a nutshell this is what you would do to log using the Torque Pro app:
1. Main settings, data logging and upload, select what to log, select the '3 dot' symbol, Select what to log, 000_Battery power and 000_State of Charge Display.
Add anything else you want and "OK".
2. Set checkboxes: Log when Torque starts, Only when OBD connected, Rotate Logfiles and Format log values all checked. All others unchecked.

3. Once ready to go at the charger, just plug in the dongle and enter the TP dashboard, keeping the device (phone) 'on' for the duration. It should indicate "logging started". If you miss that, you can also verify it starting by entering the dashboard settings menu. You will see there is an item "stop logging", an indication that it is already logging.
4. Once done, exit the dashboard. That leaves you with a data file stored on the phone.

When convenient you can export that data, specified as a CSV file, via email or cloud service. Graphing in Excel is for another day ...

 

From stageshoot over at SpeakEVs we have a similar test on an Ionity 150kW posted today with a very warm battery, 34°C ending at 46°C. At risk of raining on his parade, here are his numbers in summary (left column) compared with yours (right column):

12% to 60% 71Kw+ --------- 12% to 54% 66-72kW
60% to 76% 56Kw ---------- 54% to 75% 44-48kW
76% to 80% 36Kw ---------- 75% to 78% 35kW, 78% 24kW
