why are Tesla charge connectors so much smaller than CCS etc.

My observation is that these 800-900+V pack architectures (I think some even play games to only charge at 800V while the power train is 400V) can sustain a higher average C rate than 1.5. IIRC the Ioniq 5 has demonstrated this capability. According to this inside EVs article, the Ioniq 5 has an average 2.3 C rate from 10-80%, 50% better than 1.5. I think a move to 800+V charging on Teslas could really cut down time on road trips.

800v has nothing to do with it. If the Hyundai story is true it is a mixture of accepting degradation and/or hiding capacity

Revisiting this as now the NACS released by Tesla has put specs out there and a full teardown of both systems by professionals determined it is Capable of 1MW charging. Not currently implemented, but it could.

Is also called out as smaller, less cumbersome, and all around better. For now. 12/31/22.
