It looks as though Tesla is pursuing mobile battery swap technology for its cars.
In 2013, Tesla held an event to show off a 90-second battery swap as an alternative to charging. The first battery swap station then opened in late 2014 and by mid-2015, Tesla CEO Elon Musk admitted people didn’t really care for it. The company eventually shut down the station in late 2016, choosing to focus on expanding its Supercharger network. But a recently published patent application suggests the American electric automaker isn’t ready to give up on the technology.
Published on September 14 by the U.S. Patent and Trademark Office, the patent application details an alternative method of battery swapping, which would be done on a trailer. It would allow the service to be mobile, meaning Tesla doesn’t have to build a permanent station in the middle of nowhere that no one will use.
“A battery-swapping system can be implemented on top of a trailer for increase mobility,” reads the patent application. “Generally, the battery-swapping operations should be performed in an enclosed or at least covered location. For example, a trailer can be custom built with sides that pop out for increased space, and ramps on either side so the vehicle can be driven in and out of the battery-swapping facility.”
In addition, depleted battery can be charged at the location of the swapping system, while fully charged battery packs can also be delivered to the location.
