I recently in the installed a gen 2 wall connector with 40A. But the car shows 24A I dont know what i did wrong
Totally guessing here, but I think you might have to connect to the WiFi SSID of the wall connector's web home page during the first 5 minutes when it is first powered up and configure the power load settings via a browser to 48A. Check your install manual, it has the ip address of the wall connector when it is first powered on.
24 amps is the max your onboard charger supports on 3-phase electricity (24 x 3 = 72 amps). That's ~17kw... as fast as it gets.
Looking at the EU manual i'd say check out your dip switches and rotary dial. maybe you have the dial set to 7 instead of 8.
