I'm not quite sure if I correctly understood what you meant, so
correct/explain more if I get it wrong! My sole goal with the
infrastructure part of the tagging is to specify if a connection exists
sometimes, always or never. In the case of solar panels, even though
they don't produce electricity at night, they are always connected so
the building would then be tagged as 'electricity:generator=yes'.
So far, I've not even attempted to incorporate the method with which the
generator is connected to the grid (if there is a connection). If think
for that it would be easiest to have a separate tag. Overall, I think I
mean to only generally cover all cases, but perhaps with not as much
detail as you envision. I think that needs more and different tags to
keep things clear.
As to the electric vehicles, I think it would be fine to then tag
electricity:battery=yes and then have a separate tag like
battery:type=electric_vehicle or some such.
