The automotive company may be working on a lift that can move vehicles and swap the batteries with fresh ones.
The patent application reads: "A system for exchanging an electrical energy storage system (EESS) of an electric vehicle, the system comprising: an EESS exchange station configured to position an electric vehicle in x and y directions; a vehicle lift configured to raise the electric vehicle to a predetermined height; an EESS lift configured to raise toward the raised electric vehicle until the EESS lift is correctly positioned relative to a first EESS, to engage the first EESS, and to lower the first EESS; and an EESS conveyor located underneath the EESS lift, configured to receive the first EESS after the first EESS is lowered by the EESS lift, and configured to present a second EESS to the EESS lift, wherein the EESS lift is further configured to raise the second EESS to the electric vehicle."
It comes after Tesla announced plans to install Supercharger stations in cities, starting in downtown Chicago and Boston
They wrote: "Now, as part of our commitment to make Tesla ownership easy for everyone, including those without immediate access to home or workplace charging, we are expanding our Supercharger network into city centers, starting with downtown Chicago and Boston.
"Supercharger stations in urban areas will be installed in convenient locations, including supermarkets, shopping centers and downtown districts, so it's easy for customers to charge their car in the time it takes to grocery shop or run errands. They also have the same pricing as our existing Superchargers, which is far cheaper than the cost of gasoline."
