There's an embarrassing amount of confusion and misunderstanding in this thread for what is supposedly a technically savvy audience. The current Tesla charging standard is not NACS. NACS is a new standard based on CCS protocol with Tesla's plug hardware (SAE J3400 connector). There are very few Superchargers that support NACS, they're mostly still on the old Tesla standard. This means the US and Europe essentially have the same charging software, with different plugs on top. All the automakers already had to and intended to only support CCS. Tesla's plug just makes more sense for the US's 1-phase power compared to the bulkier CCS plug which is designed for 3-phase power. NACS is just using better hardware with the software they already have.

Are you sure about that? If so, can you cite a source explaining the difference between the current Tesla charging standard and NACS? Because that's contrary to everything I've read about it before. E.g., https://www.tesla.com/blog/opening-north-american-charging-standard https://www.tesla.com/blog/opening-north-american-charging-s... says this: > We invite charging network operators and vehicle manufacturers to put the Tesla charging connector and charge port, now called the North American Charging Standard (NACS), on their equipment and vehicles. NACS is the most common charging standard in North America: NACS vehicles outnumber CCS two-to-one, and Tesla's Supercharging network has 60% more NACS posts than all the CCS-equipped networks combined.

As far as I’m aware, any V3 superchargers (and the upcoming V4 ones) support CCS/NACS fully. Only V2 ones do not support this, and Tesla hasn’t been deploying V2 superchargers for a few years now. Anything rated for 250kW is a V3 supercharger.

  V3 supports Tesla's implementation of "NACS", which is not what was opened up to everyone. You're more than welcome to grab a NACS-CCS conversion plug to try, it won't work because it's not speaking NACS protocol, it only has the NACS connector. Right now there's only a handful of "magic dock" truly CCS/NACS compatible superchargers that speaks the CCS/NACS protocol that works with non-Tesla vehicles[1]. 1: https://www.plugshare.com/map/tesla-ccs-locations https://www.plugshare.com/map/tesla-ccs-locations

    You're mixing up "speaks NACS" with "has a built-in adapter from NACS to CCS".

"Toyota and Lexus customers will have convenient access to more than 12,000 Tesla Superchargers across North America." Isn't that most of the US ones?

> There's an embarrassing amount of confusion and misunderstanding in this thread for what is supposedly a technically savvy audience. ? ? ? Let’s correct your misunderstanding, then. 1. The US has 3 phase power. 2. The difference between NACS and CCS1 plugs is that NACS just combines the DC and AC lines into the same wire. Since the lines support both single and multi-phase AC power, and DC, the only downside of multi-purposing the line is that the car needs to make sure it’s routing the negotiated power to the correct place. 3. The protocol that any new supercharger speaks is the CCS protocol.

  Residential areas in the USA tend not to have 3 phase power. In several (not all) European countries, it's normal to have 3 phase power in your garage, kitchen and laundry room -- even in apartments. In (almost?) all of them, it's normal for any business to have it. That means the typical destination and many home chargers are using it.

    Single family homes in the US tend to be single phase 2 pole 120/240. Some medium density residential, generally high density residential, commercial, & industrial are all 3 phase.
