Two seperate problems working out how much current a battery takes to charge is **** easy.

And the rest of it? Communicating that back to the house's smart meter
for example.

My point was: they cannot even make a standard smart meter for flexible
tarrifs that is universal (can be used by any supplier).

How are they going to manage to make a smart meter that communicates
with one or more loads, given the suppliers are still stakeholders, and
now there are dozens to hundreds of stakeholders at the load end.

My point is not that it is technically infeasible (it could be done).

It is that it is commercially infeasible as there are way too many
stakeholders.

It will go the way of the NHS central records system - a lot of money,
won;t work right and will go on forever.
