Tesla’s electric cars have been labeled the future of the industry. At the moment, the only difficulty with this is charging time and locations. However, with the new patent filed awarded this week, charging your Tesla may soon be as easy as swapping out the battery. The battery swap would theoretically take about half the time it takes to charge a battery fully using one of Tesla’s superchargers.

Tesla won a patent for a machine that allows technicians to swap out battery packs completely, meaning owners could deplete one and insert a new fully charged one. The system described in the filing, which was first spotted by Electrek, would make it possible for technicians to swap out Tesla vehicle battery packs in less that 15 minutes — making it feasible for Tesla owners to use a battery exchange rather than constantly having to charge up.

The machine would be used to lift a car to a predetermined height, likely according to which model is being serviced, so that technicians can access the battery packs. The patent explicitly mentions the Model S and Model X, but other Tesla vehicles like the Model 3 would probably be compatible with the system, too.

Despite the huge upside for Tesla owners, the machine looks most promising for Tesla’s upcoming semi-truck, which is scheduled to be unveiled in October. This, of course, is all speculation based off a patent though, so we can’t say for sure whether Tesla is actually building the system or whether it plans to use it in the near future.
