Using street lamps as EV chargers

Do these chargers require payment for the charge?

What prevents "squatting" at a post (either with an EV or an ICE)?

Just thinking of my neighborhood (THs, not flats, but still no dedicated parking), there's a lamp every 4th or 5th home, and most households have ~2 cars. People mostly park in front of their house today - if you have an ICE, but also a lamppost, it's a negative - you no longer get use of the closest space (or, you take the EV spot from an EV).

The neighborhood solved this by allowing a charge cable to the spot closest to your house. But, that's expensive to install, so not many have done so (electrical panel on back of house, parking on front, so interior cable pull through finished space of home, charge unit on front exterior wall, then conduit through yard and public sidewalk for the cable run to parking). Of course, this doesn't help with apartment parking or true public street side parking (our neighborhood own the parking lot as a shared amenity).

I'm not sure about these particular ones. But I've heard that some similar chargers can get a unique ID for your car through the charging cable and use that for billing.

This is ISO 15118 https://en.wikipedia.org/wiki/ISO_15118

The model I have seen is that there's a cost for charging as well as parking after charging has completed. You get 20 minutes after charging has ended for free but there will be a blocking fee afterwards as long as the cable is still connected to the car and will be charged as part of the charging fee. If someone charges their car and then disconnects the cable and blocks the spot, they will be towed as the spot has a notice that it's only for charging devices.

I have seen those attached to light posts here in Germany but they all are in front of public area, not private houses so I guess it's only for charging, not parking.

In another point, if it's in front of a private property and the owner plan to occupy it for themselves, it would not make sense to install charger there as even when the owner is not charging, no one else can use.
