Charge rate drop off curve before and after the
HIGH VOLTAGE BATTERY MONITORING UPDATE
(SERVICE CAMPAIGN 960) US
On our road trip from Florida to New York, before the SERVICE CAMPAIGN 960 update, using the Electrify America charging network, we found that the charge rate drop off curve (blue line on the graph) to be fairly accurate.
Hyundai updated the software on our Kona, but we have not tried a DC fast charge yet.
I did find someone in Germany that had the update that shows the new charge rate drop off curve (green line on the graph).
According to my calculations, and using my previous road trip as a guideline, the time to charge from 10% to 80% was about 50 minutes.
My calculations after the update comes out to about 45 minutes for the same charge using the new charge rate drop off curve.
I don't know what the curve is for a 50kw charger, we only used the 125kw and up.
I’ve only put about 200 miles on since the update and don’t see any difference in range or performance. I have found that the car “wakes up” to check/charge the 12 volt battery and do other maintenance. Don’t really like that since I can’t change it like before with the “Aux 12v battery” setting.
