Yes, of course it's possible, Elon Musk demonstrated fast swap for Tesla back in 2013 and it went absolutely nowhere, because logistics and cost are not viable.

Yes, of course it's possible, Elon Musk demonstrated fast swap for Tesla back in 2013 and it went absolutely nowhere, because logistics and cost are not viable. It is not in any way green to replace an old battery pack that has 90% capacity and no operational problems with a new battery pack, even if that new pack has more range. The most green approach would to continue to use the old battery pack until it is unreliable. Not to mention that there is a real cost to providing new extended-range packs as replacements for old ones that will be passed on to the consumer, even as technology progresses. Unless I deeply needed that added range, why wouldn't I just choose both the greener and cheaper solution by paying literally nothing and continuing to use the old pack? Most of us EV owners already get on the road "faster than using a petrol station" since we charge overnight and spend literally zero time waiting for the car to finish fueling. There is no more risk to charging my car at home than running a vacuum or the dryer. Battery packs used in EVs since the aughts have been remarkably resilient and completely unnecessary to exchange. Battery swaps are a niche here, not a primary use case - given their size and cost it will be especially expensive and difficult to coordinate even if the swap itself is easy.
