This is my approach to build a charger for those, who have Tesla US imports. First I have built that for Nissan Leaf my Wife owns. As these charge via single-phase charger, using 3-phase 16A (typical across Europe) gives no good speed (all you have is 3,3 kW, and phase is fully loaded, so nothing else can run there).
My solution combines two phases and using this, including built-in grid monitoring (auto slowing down when other load detected) and voltage boost (+10V, not more than 250V) such US import Tesla charges with a speed up to 7,7 kW, and with 16A breakers and grid monitoring on - you can run 7,0 kW safely.
What is your opinion about that idea? Are there many owners of Tesla US import here?

Yes, I know that such a car is rare here (as I have mentioned, I developed that charger for Wifey's Nissan Leaf).
Accelev 8kW can deliver maximally 36A with voltage boosted by 10 Volts, so this equals to 36 * 240 = 8,6 kW.
Please remember, that this charger is oriented to those, who own 16A 3-phase sockets (most common in houses in Europe).
