How does battery backed megacharging work?

Electrical energy is drawn from the power grid, converted into direct current by an AC/DC converter and then temporarily stored in batteries. The DC voltage of the battery buffer is adapted to the voltage of the vehicle via another DC/DC converter. Thanks to the battery buffer, higher power can be delivered during a charging process than would be possible with a mains connection.
