Volkswagen, Audi, and Porsche Finally Commit to Using Tesla's NACS Plug

> The announcement shouldn't come as a surprise to anyone following the industry, because nearly every other major automaker (Stellantis is now the only holdout) has already committed to using the connector that Tesla developed and uses on all of its cars since 2012. The Volkswagen Group really had no choice but to make the switch, or it would have been at an enormous competitive disadvantage.

For context, North America is the second largest auto market after China.

Anyone know how the NACS plug works with the cybertruck for powering your house?

Specifically, the NACS plug doesn't have a neutral conductor, so how does the neutral current get from the inverter in the car into your house wiring?

If it's 220V from the car to the house and the neutral is generated in the wall box, that's gonna be expensive - you need power electronics to output a peak of ~100 amps at 110V, all because the NACS plug is missing a conductor.

J1772 also lacks a neutral conductor. The 3rd largeish pin you see in the plug is actually a ground connector. Its longer so that its first to make last to break which is a requirement for most ground pins. I assume both J1772 and NACS use their ground conductors for neutral when in V2H mode since a ground conductor wouldn’t really do much when the car is feeding power to the home. Both plugs have 5 pins.

Considering that the Tesla Supercharger stations are the gold standard for EV charging, is the decision to adopt the NACS plug by other car makers caused by the ability to use superchargers?

Mainly, but also the plug is smaller and easier to use than CCS1.

In Europe there’s a slightly improved CCS2 plug (without a latch sticking out), and all automakers including Tesla use CCS2. Superchargers aren’t dominant, and there’s no push to change the connector.

Thank you. It seems to be a no-brainer for other manufacturers to adopt to a common standard with additional benefits to their client base.

It's a welcome change, especially after years of proprietary solutions to shared issues.
