Tesla's Supercharger Team was recently laid off. We discuss what this means for the company on today's TMC Podcast streaming live at 1PM PDT. You can watch on X or on YouTube where you can participate in the live chat.
They might have designed the charger for doing this, but I don't see them enabling it anytime soon for use in your house. There are all types of problems with allowing this in the home without proper protections installed. There needs to be some way to prevent islanding during power outages. On the other hand, providing the ability to give somebody who ran out of juice a little from my car would be useful and easy to implement.
Some options will be hitting the market UL certified this year and are in BETA now. Will Tesla play nice with them...who knows. See EV Charger, Solar Inverter & Energy Management - dcbel Not sure on 3 or Y but you can take power out of a S just fine via the chademo adapter.
There was a PCB analysis of the internal inverter and it was proved that this is not currently possible for cars in production....the design of the electronics prevents any power from going out.
I actually emailed sandy about it, he confirmed the 2020 Model Y charger board has the same components and is incapable of bidirectional charging unfortunately.
HOW? Are you thinking that dcbel and the Tesla CHAdeMO adapter will allow power out of a Model S?
dcbel says "a Nissan Leaf or Tesla Model 3 can hold anywhere from 40 to 62 kWh of power." I know them mean 62 kWh of ENERGY, not power. dcbel seams to imply that a Tesla Model 3 could power my house, but we know that's not true. The M3 does not have a bidirectional charging port.
Well you could close the DC contactor like when Supercharging and that connects the battery to the charge port but that is DC. You still need a grid tie inverter to make AC and make it safe.
The discussion above was about using the on-board charger bidirectionally to output AC from the charge port. That is not possible from the analysis I have seen.

***So all Tesla cars have a DC bidirectional charging port. *** The charger in the car is not bidirectional, but the charging port is DC bidirectional. Thanks.
The Tesla's drive motor's inverter could be hardware and software redesigned to be a grid tie inverter to make AC that goes backward through the WC (HPWC) to the house and grid.
Fiddler - You know that the drive inverter is wired directly to the motor, right? The assembly is called a drive unit and connects to the car with a high voltage DC connection and a data connection. That's it. So AFAIK that won't do it.
