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

sorry if numbers scare you

Only when they're pulled from your ass.  No telling what's been up there.

Out in the future, I'm fairly confident we'll see inductive charging.

I'm not sure at all. The cost required to put inductive charging into roadways is astronomical. And the efficiency of inductive charging is probably not enough to make it worthwhile. I don't see it happening.

A battery swap required exposed contacts.  Not a good thing in winter.  And batteries degrade over time, so you could well end up with one with half full charge.

Also note that for a battery swap, you need a LOT more weight and strength in the chassis to make them easily removable and replaceable.

I'm reminded of motorcycles where all modern sportbikes use the engine as a stressed member of the frame. I'm guessing that in a modern BEV, the batteries don't just "ride" in the frame, the battery packs are part of the frame. 

Once you make them removable and they ride in the frame, you have to beef up the frame significantly, which of course adds tons of extra weight. 

Then your point about exposed contacts is important. You need contacts that are removable, but also capable of handling all the shock and vibration of a moving vehicle. Whereas a static battery pack will have fixed connections. 

There are SO many logistical and engineering issues with battery swaps. Not to say that they won't ever be solved, but I'm guessing that much like inductive charging, the solution will be to improve the rapid charging infrastructure rather than to go to battery swap tech. 

At least you got the right youre, sort of

Many people following The Science here.

Well, there are three main concepts, one already in use:

1.  Normal charging, including supercharging, which is capable of 75 miles range in 5 minutes.
2.  Battery swaps, really in the concept phase.
3.  Induction, which is more of a costly dream at this point, technically possible.

If you need long distance capability, charging becomes less attractive for obvious reasons, but most  driving is intercity where that isn't really an issue.  An EV with 250 miles range will get you to work and back easily (I hope).  Then you charge at night when power needs are low.

The strain on the Grid for day charging in July could be a factor.

I've seen figures ranging  from 25% to 40% of additional generating capacity needed if we were all electric, including trucks.

Electric Cars Will Challenge State Power Grids | The Pew Charitable Trusts (pewtrusts.org)

A U.S. Department of Energy study found that increased electrification across all sectors of the economy could boost national consumption by as much as 38% by 2050, in large part because of electric vehicles. The environmental benefit of electric cars depends on the electricity being generated by renewables.

University of Texas at Austin estimated the amount of electricity that would be required if every car on the road transitioned to electric. Wyoming, for instance, would need to nudge up its electricity production only 17%, while Maine would have to produce 55% more.

At a time when many want more wind and solar, it's useful to note that an additional demand due to EVs recharging will make that even more of a challenge.   The rate of increase over time has been significant, up to 2007.  We increased from 3,000 to 3,700 from 1990 to 200, so large increased are possible, but of course that was significantly using coal.

It will be tough to keep up if our new sources are limited to wind and solar.  Tough as in mathematically impossible.
