Hello, I have an EVCS with a display and a Tesla Model Y. The wallbox is connected to 3 phases, 32A, and I have set the charging limit to 17A. The car is charging at 5A, and the cable is properly calibrated.
Sometimes, during charging, the session stops unexpectedly. If automatic charging start is enabled, the charging resumes within 3–5 seconds.
However, in that case, when I tried to stop charging from the car, it restarted within 3–5 seconds and the cable remained locked. The wallbox does not show any error message, but the vehicle displays a warning about power loss.
Also, in manual mode with autostart disabled, I’m unable to configure the wallbox to stay connected to the vehicle after charging finishes – which I need for preconditioning the car.
The wallbox behaves the same regardless of the “Contactor active when charged” setting.
Thanks in advance for any advice.
