As you can see in the image above, the rig has the power to lift vehicles, allowing technicians easy access to the whole car as they help the machine change batteries. It won’t enable 90-second swaps like what Tesla originally promised, but waiting for 15 minutes isn’t bad at all if you find yourself low on power while driving between cities or states and there’s no Supercharger nearby. The rig in the patent was designed to service the Model S and X, but it’s not hard to imagine Tesla making one that its electric trucks can use.
