I 'spect there's still some nitwits here who still don't believe it.

Smart meters will be able to identify electric cars and charge the
missing fuel duty, VAT and climate change levy (from the coal-
fired powerstation) to your leccy bill. Ha Ha

No they won't.

Hmm.. something might. Assuming full wave rectification, the battery
will only draw current when the supply voltage exceeds that of the
battery. I doubt it would take much electronics to spot that.

That could work with a very old-fashioned car battery charger, but an EV
charger will be a sophisticated switch-mode unit with power factor
correction.
