How to read the visual

The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.

  • We use 350 kW for the rated DC output of a motorway rapid EV charger; the recorded range is 50 kW–400 kW.
  • The rated DC output of a motorway rapid EV charger: This is an illustrative comparison value, not a claim that every example is the same.

Power is the rate of energy transfer or use, not the total energy.
