In Germany a lot of charging stations are built by the electricity grid operators. So they usually end up on parking lots of stores or near municipality buildings(a lot of them are owned by the local municipality). Howver neither puts up some big signs to really advertise it. So it is easy to miss them, even when using a navgation system. Like there should be one on the parking lot, but it is behind the building or some weird stuff like that.

That being said there is easily enough of them to cover the country.
