Tesla has a solution for diagonal Supercharger parking of other EVs as its 350kW V4 stations hint
The recently installed Tesla "Magic Dock" Superchargers that allow charging of other electric vehicles in the US are still in the trial run stage as they are few and far between. Apart from the scarcity of CCS-compatible Supercharger stations on this side of the pond, another issue is the location of the charging port on non-Tesla vehicles that is all over the place.
Tesla Superchargers have a rather short cable calculated to reach the strategically placed port at the rear of the Model 3, Y, S, and X. With the opening of its American charging network to other electric vehicles, however, Tesla is also warning their drivers not to park diagonally and take more spots than needed as their ports can be on the back, but also at the front or on the sides.
The warning seems lifted directly from Tesla's European app where non-Tesla vehicles have been allowed to top up at Superchargers at higher prices for a good while now, starting with a pilot in the Netherlands. It's again the Netherlands, which has the densest network of EV chargers in Europe, where Tesla seems to has chosen for a debut of its next generation of V4 Superchargers.
Capable of 350kW power delivery, as opposed to the current 250kW that its stalls top out at, Tesla is likely planning for this to be its default charger installation going forward. The V4 stations look larger than Tesla's current stalls, though not as tall as the Semi truck chargers. The size would offer one undeniable advantage as the cable at the V4 Supercharger is evidently way longer than the one Tesla uses now, so charging any EV on it won't have to be a parking and placement challenge.
Those who spotted what could be the first V4 Supercharger station near a highway to Amsterdam, also note that the parking spots before each stall have been enlarged, too, adding further to their better EV charging ergonomics.
