What is the currently maximum available performance of NACS?
CCS is designed up to 1000V and 500A. Charging stations offer typically up to 350 kW.
What do the available NACS charging stations offer? As I remember Tesla is only using 400V batteries, so with 500A they only get up to 200kW.
So the switch to NACS sounds like a performance downgrade. But yes: probably a usability upgrade but at the cost of longer charging times.
Is Tesla planning to switch to 800V too? So they can deliver more performance?
Looks like there is a 1000V variant. I'm guessing there just aren't any chargers built with it yet.
North American Charging Standard Technical Specification 6. Ratings 6.1 Voltage Rating The North American Charging Standard exists in both a 500V rated configuration and a 1,000V rated configuration. The 1,000V version is mechanically backwards compatible (i.e. 500V inlets can mate with 1,000V connectors and 500V connectors can mate with 1,000V inlets)
