Note that Model Y’s aren’t a good data point (yet) either. These inspections are only required after the first three years of owning a new car (and then every two years thereafter), and Grünheide hasn’t been running that long. Thus, while there are German-made Teslas on German roads, they aren’t showing up for the mandatory inspection just yet.
Additionally, this inspection looks at technical roadworthiness, not at overall build quality.
Different hardware might handle charging at different speeds. Given that I’ve personally never heard of a vehicle charging at 11 kW on a single phase, I’m all but certain the dealer was referring to the difference between single-phase and three-phase here.
A rough rule of thumb for charging losses is: 15% for single phase level 1, 10% for three-phase level 2, 5% for DCFC level 3.
It varies from car to car, obviously. But the hardware handling three-phase charging is always less lossy than the one handling single-phase.
Expanding into Europe first makes more sense because the European EV market is bigger and growing faster than the US one.
Additionally there is less anti-Chinese sentiment in the EU.
