Hi,
If you want to go from 30 to 80% (i.e 50% of the 41 kWh total capacity), you need to add around 20 kWh.
The R90 can charge at max 22 kW (if the battery pack is not too cold), which means you need around 55 min for this.
The Q90 (which is not sold in Norway so you would need to import it or find one already imported) can charge at max 43 kW which would then give you 30 to 80% in half the time so roughly 30 min. But then you have to find a 43 kW AC charger.
