Tesla has launched its battery swap pilot program by inviting selected Model S owners at a custom-built facility in Harris Ranch, California.

The said pilot program intends to test Tesla's battery swap technology. With this, the selected Model S owners are given the opportunity to swap their car's battery to a fully charged unit instead of having to wait for a charge.

Tesla says the battery swap will be available by appointment and will cost “slightly less than a full tank of gasoline for a premium sedan.” The automaker added that the battery swap process takes approximately three minutes because the titamium and the hardened aluminum ballistic plates are to be remove. On the other hand, Tesla claims that with further automation and refinements, the “swap time could be reduced to less than a minute.”

Watch the video posted below to see how Tesla's battery swap system works. As a reminder, the video is Tesla's demonstration in Los Angeles last year.
