The official database for charging points in Norway is NOBIL which is maintained and paid for by Transnova (a public organization for supporting energy efficient changes in Norway) and NORSTART the EV organization. NOBIL is available for cellphones and webpages to access the data, the largest webapge currently that shows the data in the database is Ladestasjoner. It is in Norwegian but the map should be pretty easy to use.
