Hey,
in this case, the amenity=charging_station is mapped as a way (www.osm.org/way/1329580649) which also includes the parking spaces which are designated for EVs. The man_mad=charge_point is the position of the actual station (with its 2 sockets). This degree of micro mapping would't be needed here for only one station but it's a nice convention for combining them when there are multiple stations at one locality
