The charge wire has to be big enough to carry amperage. Assuming 100 amps, that's 940 volts.... let's say 1000. Is that about right?
So the long and short of it is if it is getting the full 120 Kw from the stall the battery will see roughly 400 volts at 300 amps. So let’s say you just arrive in stall 4A and someone is just finishing up in B. If the two stalls have one of the 150 KW power supplies and the first car has tapered to 40 KW (almost charged) your side will have 110 KW available.
It works the same for dual station non Tesla DCFC (dc fast charging). Eg, our leaf for example. Just the numbers are smaller.
Hope that helps. Helpful bunch on the Tesla Forum.
