I don’t know exactly for Norway as that was the best English article I could find. A standard danish outlet (they are crap) is 16A but is not rated for more than 6A if the load is continuous for more than 2 hours.

Then use a 6A charger? Assuming it's 2x the voltage of the US that's the same power as a 12A charger would be in the US, and I get plenty of charging at 16A (which is the maximum continuous load on a 20A circuit)
