    Do the simple maths:

    A 240VAC 50Hz 15A power point delivers energy to charge a battery in 8 hours (say). To do it in 8 minutes will require 60 times the current. All variations in parasitic losses being ignored, of cause, these work against you. The same total energy has to wind up in the battery at the same temperature.

    It's not magic, its maths.
