[Suggestion to use amenity=charging_station + charging:bicycle=yes +

I remember having been told off by someone who doesn't like
namespaces: "we are not doing like that" ;-)
People on this list have strong opinions. Often those opinions are in
opposition. But whoever told you not
to use namespaces is ignoring the fact that OSM already does use
namespaces. If most people say yes
and one person says no but presents no valid argument for his
objection, ignore that one person.
OK, but they shout louder and the problem is that it's the other
contributors who must ignore them.
And it's painful to read replies with just what is sub-optimal in a
proposition and no better alternatives towards the same goal.
But you are, like me, perfectly right using it because we could have
charging:bicycle:amperage=* different from charging:car:amperage=*
Do we need it?
Please understand what I meant.
I'm just demonstrating the general versatility and usefulness of
namespace, not discussing amperage.
"could have things like..." if you prefer.
(But then, charging:amperage=* won't hurt and be consistent)
The connectors have a maximum amperage, which may fall off as the battery
becomes nearly full, or because battery temperature monitoring
throttles the current. If there are
different physical sockets for cars and bicycles then you specify
their maximum current with
socket:typeX=7 or whatever. If it's the same socket for both then you
just specify the maximum
current and it's down to whatever you plug in to draw as much or as
little as it needs.
You'd only need the charging:bicycle:amperage if it's a common socket
but with the smarts to
detect what kind of thing is plugged into it and limit the maximum
current accordingly.
All that said, if cars and bikes have different sockets then tagging
the socket type is enough
to determine if bikes can charge there. If it's a common socket then
the maximum current is
enough to figure out if you can charge only a bike, or a bike and a
car, or a bike, a car and a
truck there. Of course, there may be other constraints: the charging
point may have a connector
capable of being used by bikes, cars and trucks but trucks won't fit
in the parking space and the
operator doesn't like bikes taking up a socket but only permits cars.
Which puts it into the
realm of access restrictions.
