There is a bug on the display on both the phone app and car display. I have found if I change it on my phone app, it will charge at that rate, even though the next time I go into the phone app, it is different. The car display is also different from the setting I make every time I get into the car, but I assume this is also just a display issue. The latest software I have seems to have fixed the car display 2022.4.5.20. Checking the phone app and it is also showing correctly now.
Non-Tesla EVSE wall connector (Open EVSE). Everything was working fine since 2019 and prior to V11 update.Are you using a mobile connector or a wall connector? Or non-Tesla EVSE?
My charger will allow much higher amps. The issues are the charging cable and the service wiring. The cable can do 40A+ I think, but the outlet service wiring is rated for 30A, and you generally want to limit the load to 80% of the rating to prevent overheating of the wire. So, 24A is the magic number for me, and now I have to set it each time. Thought maybe I was missing an new setting, but apparently not.I have the Gen 3 wall connector. Should be able to charge at 48 amps, and can set it to such, but I find that it seems to want to switch to 47 amps. I assumed it was doing that for some cosmic reason and the difference is not that great so I have ignored, but it is curious. I do have a rather long run to the garage but we used thick cable so 48 amps should not be a prob.
Why would you not configure the EVSE to provide the correct maximum current instead of relying on the car to do the right thing?My charger will allow much higher amps.

I do have the EVSE set to 24A. I have never tried to see if the call for more from the car makes a difference. I have thought about trying it.Why would you not configure the EVSE to provide the correct maximum current instead of relying on the car to do the right thing?
Presuming the EVSE is configured correctly and J1772 compliant, the car will never be able to draw more than the EVSE is configured to provide.I do have the EVSE set to 24A. I have never tried to see if the call for more from the car makes a difference. I have thought about trying it.
The charging is limited by power (kW). So if you have high voltage it may reduce the current. What is it reporting for voltage?I have the Gen 3 wall connector.

It’s limited by power. If your voltage is on the high side of the scale, it will reduce the amps. Not sure if this is what you are seeing, but it did surprise me. For whatever reason, the voltage at my house is frequently high.I have the Gen 3 wall connector.
