At what cost to the owner and then what do you do while you get charged

Can't imagine how that would work economically for either party unless they had very good market saturation. 

Can't help think there would be demand for a small swappable battery BEV even if the range is only 20 miles or so.

So some ones test of a bev and running down the battery to 0%

Does running to zilch have any detrimental effect on the battery?

No because zero isn't really zero, that's just what is being reported to the car, the BMS is there to prevent damage to the cells by not letting them drop under the nominal voltage.

I seem to recall occasions where Tesla has extended battery cvapacity remotely during hurricane evacuations and the like, by sending an OTA update to let the car use more of the available capacity.

That would very much depend on the BMS, any allowed running under Turtle mode and such things as parking up and letting the battery discharge through neglect. I wouldn't try it frequently, bearing in mind that the BMS is likely to record such events. Nissan do a battery report every service and frame it as as "how you are treating your battery".

This announcement from CATL is exciting the YouTube airwaves. The LFP version has an energy density of 160Wh/kg at the pack (not cell) level, so very, very impressive, and could make batts ~30% cheaper. It also seems their pack design manages the temp so well, that a 0-80% charge is possible in 10 mins.

Unlike many battery breakthroughs, this one appears to be near finished with mass production starting in 2023.

They have now managed to bring its energy density up to 255 Wh/kg. Charging times have dropped too, with CATL noting that with this new tech, charging from 10 to 80 percent will be possible in about 10 minutes, or as low as 5 minutes with a ‘hot start’ which we presume means preconditioning the battery beforehand.

The wife ran the leaf completely flat a couple of years ago, I've put in in turtle twice before that.
Still showing 85miles at full charge now, so I see no massive effect.
It showed 82 miles when full when we got it 3.5 years ago, and it always gets charged to 100%.

1 story doesn't make global facts, but thats my experience
