Drivel. As usual you are "expert" on something you have zero
knowledge and experience of.

Its simple arithmetic harry. 13A @ 240V for 8H is ~25kWh - about the
same energy content as that contained in 5L of petrol.

No-one runs their electric car to depletion. Or anywhere near.

You say that like its a good thing!

While its understandable, since the pain of actually running out of
power is considerable, it means even less of the energy stored is
available for use. Less of a problem if you have "loads" in the first
place, but more difficult when you need all the range you can get.


You only need a gallon of batteries to get it going again don't you?

I can see a market for some kind of portable power bank for getting a EV
to the nearest charging point... kind of like the power banks for your
phone.

(perhaps a hole on the dashboard that says "Insert 400 x Alkaline AA
cells here)
