In 2015, Tesla released a video demonstrating a prototype “snake charger” that (presumably autonomously) connects and charges a car. It’s amazing and honestly not as creepy as I might have imagined.
I missed this prototype at the time and apparently not much has happened with it in the interim, but recently Elon Musk confirmed on Twitter that the charger is still in the works.
This charger would make a lot of sense were Teslas able to drive autonomously, as Musk hints they will be able to do soon (note that a lot of people are skeptical on that point). Autonomous charging would really untether the vehicle from the need for human intervention.
At this point neither the snake charger nor Full Self-Driving mode are ready. But it’s a pretty awesome video.
