So they always had it, just disabled in software?
> By default, all Cybertruck trims ever produced and all Model 3 and Model Y vehicles ordered in the U.S. and Puerto Rico after October 1, 2026 are capable of Powershare. Some, but not all, Model 3 and Model Y vehicles produced before October 1, 2026 are also capable of Powershare. [0]
I presume it is a hardware revision, like how Tesla removed radar.
Or you can deploy the hardware while software is not ready...and allow it when software is built, tested and updated.
That's why Tesla gets cool features like door open pedestrian/car alert, child left behind detection, smooth stop etc over the life of the car.
Yes. Typically V2G works by connecting an external inverter to the high-voltage bus.
It just needs to start a charging session, and then siphon energy _off_ instead of supplying it. People tried that before, but the firmware on Model 3/Y monitors the flow and terminates the session if the flow is negative.
