A weakness in Vehicle to Grid concepts is that it will probably (battery not yet defined so I cannot say certainly) shorten the life of a very expensive battery.

Checmical battery life is usually a function of the # of cycles.  Using them on the grid could be prohibitively expensive.

Since EV technology is far from mature, nothing can be determined with certainity.

All true at the moment.

I'm thinking more of ultracapacitors as the basis for this setup (do a search on "EEstor" for some background) - which may be a way off (or may not materialise at all) - but it does seem to be the most promising line of development, to me at least.

Think Ultracapacitor EV.  Think bad accident with larger vehicle.  Consider breaching of container and "instant" discharge.  Think electrocution of everyone in both vehicles.

Logically, if such a discharge is unlikely to happen except in bad enough accidents where fatalities are likely, it would be an acceptable new risk.

But emotionally, not so OK.

Still

Best Hopes,

Alan
