DC�charging�station
The�DC�charging�stations�form�the�second�group�of�the�fixed�charging�stations.�In�comparison�to�the
AC�charging�station,�the�AC�voltage�is�already�converted�to�direct�current�in�the�DC�charging�station.
Therefore,�power�electronics�for�the�conversion�of�the�AC�voltage�to�direct�current�voltage�in�the
electric�vehicle�are�not�required.
As�the�weight�of�the�power�electronics�in�the�DC�charging�station�plays�a�minor�role,�large
transformers�and�a�rectifier�can�be�installed�there�to�use�the�full�network�power.�For�this�reason,�DC
charging�stations�generally�deliver�a�much�higher�charging�power�than�AC�charging�stations.�Using�a
DC�charging�station�the�high-voltage�battery�can�thus�be�charged�much�quicker.

Although�the�high-voltage�battery�of�the�I01�can�also�be�partially�charged�by�brake�energy
regeneration,�the�"normal"�charging�procedure�takes�place�when�the�I01�is�connected�to�the�AC
voltage�network�of�the�power�supply�company.�Energy�is�taken�from�the�AC�voltage�network�and�fed�to
the�direct�current�voltage�high-voltage�electrical�system�of�the�I01.
