This is a V2 Supercharger plug (V3 is similar):
Here's a V4 Supercharger plug...
...and Chargepoint's NACS plug...
Both have gaps around the outer edge (between the DC pins at the top and on each side between the DC and low voltage pins). Why is that?
Tesla's specs show this gap (page 14, among other places) for the 1000V variant and not for the 500V variant. No explanation why.
Doesn't make much sense to me. The car inlet side can't have any material in that space, or it wouldn't be compatible with existing V3 chargers. It seems like removing that material would reduce durability and would reduce isolation between the positive and negative HV pins (for higher voltage applications). Am I missing something obvious?
The only theory I have is the vehicle could use that space for a (very small) liquid cooling pipe or heatsink, if it were movable and could be pushed inwards when using an old plug.
