I just read this Tesla could ‘revisit’ vehicle-to-grid technology, says Elon Musk Yesterday, in response to someone on Twitter asking Elon if Tesla would ever allow one Tesla to connect to and charge the battery of another Tesla in an emergency situation, Elon responded: “Very early on, we had the ability to use the car as a battery outputting power. Maybe worth revisiting that.” The Electrek article states: “Tesla’s first generation Roadster had the capacity to output power from the battery pack to something other than its electric motor. The technology is often called vehicle-to-grid or vehicle-to-home and it enables electric car owners to power their home with their electric vehicle battery pack. The automaker has since dropped the technology for its more mass-market vehicles, but it is making a comeback with other automakers and now Tesla is considering bringing it back too, says Elon Musk.” I did not know that the Roadster, or some early version of the Roadster, had that capability. Is that true?
