Now that SAE is formalizing it, I wonder what conflicts can be expected if SAE becomes the organizing body for the maintenance and upkeep of the standard. Is this SAE's role? Can Tesla make a change to NACS in the future which purposely gives Tesla cars an advantage? For example, program Superchargers so only Tesla cars will receive higher charging power but downrated for other EVs?
- clouddrover 3y ago> if SAE becomes the organizing body for the maintenance and upkeep of the standard. Is this SAE's role? Yes, just as IEC maintains the standard for Type 2 and CCS Type 2 Combo plugs and inlets. The latest revision of IEC 62196 specifies support for up to 1,500 volts and 800 amps for DC charging: https://en.wikipedia.org/wiki/IEC_62196 https://en.wikipedia.org/wiki/IEC_62196 It'll be a while before cars and chargers implement that. > For example, program Superchargers so only Tesla cars will receive higher charging power but downrated for other EVs? Some EVs are already downrated in practice because Tesla chargers are only 400 volts which means 800 volt EVs can't achieve their maximum charge rate. The maximum the Kia EV6 can charge at on a 400 volt charger is 100 kW, rather than the 230+ kW it can achieve on an 800 volt charger. On a Tesla V4 charger an EV6 can only get 42 kW at the moment: https://www.youtube.com/watch?v=sEJ2KtzMeh8 https://www.youtube.com/watch?v=sEJ2KtzMeh8 On a Tesla V2 charger it gets 97 kW as expected. All chargers in North America will be CCS chargers just with Tesla's plug on the end. If Tesla chargers still can't deliver 800 volts then the solution is to use another one that does.

- Kirby64 3y agoEvery competitor that has said they're adopting NACS has stated the earliest it'd be would be 2025. Tesla is rumored to be deploying 800+V systems for the Cybertruck, so I fully expect there will be plenty of 800V capable superchargers by the time we start seeing NACS on other cars. Also, the only cars I'm aware of that use 800V for the super fast charge rates are Hyundai, Kia, and Porsche, none of which have yet agreed to NACS yet.
- clouddrover 3y ago> I fully expect there will be plenty of 800V capable superchargers There are plenty of 800 volt chargers available now, just not from Tesla. > Also, the only cars I'm aware of that use 800V for the super fast charge rates are Hyundai, Kia, and Porsche You're going by brands rather than groups but you can add Lucid, Genesis, Audi, GM, and Chevrolet as brands with 800 volt charging vehicles. More cars will be on 800 volt platforms in a couple of years. Tesla better get upgrading.
- hbarka 3y agoWe can see an alternate future where NACS becomes so successful and then Mr Musk goes on a tantrum and decides on building another Tesla plug. What reasons could compel him to backtrack or is it too late?
- Kirby64 3y agoSure, the EA 350 kW is capable of 800V. Good point about smaller brands that do have some 800V offerings. Pretty small amount of cars shipped, though, compared to Hyundai/Kia.
- CameronNemo 3y agoWait isn't this exactly what the original commenter is concerned about? The charging infrastructure will lag the state of the art until Tesla's car business can catch up. I guess that does assume nobody else builds better chargers in the meantime.
