I think you're overthinking this. I'm planning on adding a charging point to my parking space. The building's shared garage already has power everywhere so I just need to install a meter and a standard power socket. The actual charger just plugs in there and if I change EV I just change the charger (or not since everything is moving to CCS hopefully). Neighbors have done it and it was quite simple. If it's an external parking lot without power already installed it may be harder but in cities this is the most common setup. I'm sure third-party parking garages that people use when their flat doesn't include one will also be doing these installations at scale to attract customers. It's really the equivalent of adding a few power sockets. For night time charging you don't want fast charging, 10kW is fine and 5kW probably enough and that's not a very complex electrical install. The only actual issue I know of is that once the whole building is doing this because 90% of cars are EVs we're going to need more total power in the garage. Depending on the electrical infrastructure around you that may or may not be an easy thing to do. I suspect it's not a huge issue since we all together already have enough contracted power right now if you add up our individual circuits going to the actual flats. But maybe the electrical company is oversubscribed counting on low effective usage of the contracted power, I don't know.
