why is battery swapping better then battery recharging
It's faster.


And you could conceivably catch more potential battery failures that way, as well.  If they're regularly coming into stations to be swapped out for recharging, they could check for problems and potentially recondition them as well, before putting them back into circulation.  This would, of course, be more expensive, but could be a value-added service.

There are currently over 270,000,000 vehicles in the US

If you figure each one needing a recharge every 7 days thats aprox 38,000,000 each day

so you are saying every day 38,000,000 will be replaced 

while I can see exchanging if on a long trip I dont see much of advantage for those just going from

work to home each day

These batteries weigh a half ton or more. Might not be easy to swap.

you stole my thunder
I was just getting ready to post that fact
Technology will have to greatly decrease the weight for swapping to be practical

Yeah it definitely depends on the vehicle, the batteries, and the battery configuration.  But no matter what, we're definitely NOT talking about something as simple as swapping out your normal battery on your current everyday IC engine vehicle.

I've seen the proposal for "battery sleds" in a vehicle, where the whole bank of batteries slides out on a sled and is replaced with another that is identical.  I think eventually the capability to do something like that will be there, but what I don't know, is whether or not the market dynamics will enable such a thing.

Cadillac Super Cruise Review: Better Than Tesla’s Autopilot (motortrend.com)

We may end up with inductive charging as we drive, but that's a ways out.

Anything coming from the road is a long ways off, especially in colder climates.

Thanks for the meaningless numbers, lol.

I was thinking more along the lines of people charging when they're home/overnight, so many would hardly ever need to switch theirs out.  But on long trips, obviously, it would be useful, as you said. 
.
Perhaps it'd be more like an oil change, where you notice it doesn't recharge to 100% overnight or something..

It depends on the battery usage people get into the habit of.....is it a nightly thing you plug in before bed or is it a "when I remember, on the weekends" kind of thing.  Do they start wearing out after 20 recharges or 500 or 10,000?

.
All I know is that people are absolutely not going to wait around for a battery to recharge when they're trying to get somewhere.  That might be a thing in the early years of widespread electric car use, but it will not be "the way" down the (timeline) road.

This is for V3 Tesla supercharging:

 At this rate, a Model 3 Long Range operating at peak efficiency can recover up to 75 miles of charge in 5 minutes and charge at rates of up to 1,000 miles per hour. 

That's pretty good I think.  It would be nifty if the makers would standardize on a plug in type.  A car with 300 miles of range would need 15-20 minutes to recharge from dead.  You might stop every 200 miles and recharge in five minutes and drive on.

If you drive 400 miles in a day, that is two stops.  For five minutes.

the current battery weighs over half a ton so currently not likely

sorry if numbers scare you
