Technically, but not practically.<p>You&#x27;d have to have some government involvement here so that all batteries are owned by the same entity, so you can swap batteries from different manufacturers, at any energy station.<p>You also have to standardize on only a few battery types, which makes it harder to design the car, since you can&#x27;t custom fix the battery to available space.<p>And that means future battery advances are impractical - who wants to use a battery that can&#x27;t be part of the swap network?<p>It&#x27;s not realistic.<p>A hybrid power system is more practical - use hydrocarbon fuel for &gt;50 mile trips, and a battery you plugin at home for shorter trips.
