I was wandering what is wrong with just tagging socket:* tags as indicated on the Tag:amenity=charging_station - OpenStreetMap Wiki ? Socket tags are the most important there by far!
I mean, even using bicycle=only is mostly useless for bicycle owners (does it means it has schuko, so it is universal but I have to be carrying my own charger in my panniers? Or does it only have bosch_3pin so great for those bicycles and no need to carry a charger, but is completely useless for shimano_steps_5pin bicycle users?) etc. (Just like a car with chademo has a bad luck at Tesla-supercharger-only charging station or whatever).
Also, I understand there exist specialized hgv-only chargers, which won’t fit regular electric cars either.
In other words, bicycle=only would only help non-bicycle users to know that this station is (maybe) useless for them.
On the other hand, if that amenity=charging_station also was mapped with e.g. socket:schuko=4 + socket:schuko:voltage=230 + socket:schuko:current=16 + socket:chademo=2 + socket:type2=2 (+their voltage/current ratings when applicable) it would’ve actually been useful for everyone involved - be it electric bicycle, electric scooter, car, or HGV users (or even folks with laptops or phones with or without chargers).
Yes. Also, as I gather, there are some adapters to charge bicycles on car chargers.
So, that reinforces my opinion that we should tag what is actually on the ground (i.e. how many of which sockets and their capabilities) instead of our interpretations (e.g. “oh that is bicycle only charging station” – well, guess what, I likely can charge my laptop on that schuko too). It’s more verifiable too.
