The source specifies that: "Chargers between 22 kW and 150 kW are classified as fast, and ultra-fast chargers are those of 150 kW or more. Only chargers within a radius of 150 metres of the highway are included; stations with less than 4 charging points are excluded. Coverage is calculated by setting a radius of 25 km around each charging point, so actual driving distance between two charging points likely exceeds 50 km based on the curvature of the road and the routing. To determine the number of stations on the bottom axis, all charging points within 500 meters of each other are considered as one station."
