Tesla too slow for phase detection #146

After 11 seconds the Tesla is still not drawing any power; this version is patched to wait for 25 seconds for testing.... detection-25.zip

The patch works! I observed that after starting 3 phase charging with 16A as maximum sent by the smart charger via the standard PWM signal, a Tesla (Model 3 Standard Range Plus from 2019) takes its time to ramps up each phase consecutively. Ramping up each phase, it takes a bit over 5 seconds. All in all, it typically takes up to 15 - 20 seconds until the last phase reached 16A.
