It may have in the early days (just like many countries' oil programmes), however now the fund is helping to provide subsidies which makes gasoline cars more expensive than electric cars (amongst other policies), and hence Norway is now one of leaders of EV adoption (per person):
There is nothing in that article that says that the oil fund subsidises the purchase of EVs. As far as I know the oil fund is not used directly for such purposes, can you provide a reference?
