How many chargers are necessary to convert the Netherlands to electric cars?

Here is the question:

How much infrastructure do we need when ALL 8 million vehicles (and buses and trucks!) in the Netherlands go electric? The answer will surprise you: we could get to 100% electric transportation in the Netherlands, just by converting the 4000 existing gast stations to fast charging stations which have an average of 14 fast chargers.

article then plays with numbers a bit: Kilometers driven, electricity used, number of chargepoints, charging rates.

(for germans: The Netherlands compare in area and population pretty well to Nordrhein-Westfalen)
