I think it's a myth that V3 is "not shared".
0) When getting high power supercharging, like 150kW or 250kW, you are mostly getting power directly from the batteries in the white cabinets (the big ones, not the red/white stalls that you get your charging plugs from.)
1) Is it possible for 4 cars all charging at 250kW at the 4 stalls that are connected to one V3 cabinet? Yes. But this does not mean that the power is not shared. On the quite contrary, all the power is from ONE cabinet, all 4 cars are Sharing the energy delivered by one cabinet.
2) If you read the name plate of the V3 cabinet, you'll find the specifications for DC Input/Output. What is this? This is for one V3 cabinet getting DC power from or delivering DC power to other V3 cabinets.
2.1) The most efficient way to design a charging site/station is that all the energy stored in the cabinets can be moved delivered to any charge port. You don't want a cabinet with full energy without car charging while a car is plugged in another cabinet with low energy/power and the owner complains.
2.2) If you ever lined up waiting for your turn to get a V2 supercharger spot at the end of a busy holiday, take a note on your maximum charging power. Is it even 75kW or half of the 150kW V2 cabinet can deliver? Often not. Why? Because the batteries in the cabinet have run out, and you charge at about half AC input power a cabinet gets, which is usually a fraction of its maximum DC output rating.
3) Lets get back to V3, because of whole site is sharing, you get a better chance of reaching 250kW. When the batteries in the cabinet that you plugged into run low, you can get power from other cabinets. But this by no means you are guaranteed to get it when your car is ready to get it. At a peak day, after the battery of all the cabinets in a station run out, after waiting in queue for hours to charge, you'll find you are not reaching 250kW, probably much lower than that.
3.1) Even if one V3 cabinet can take 350kVA (yea about the same as 350kW) AC input, The actual site supply to it can be lower because of cost or other factors.
