6.1.2.�Overview�of�charging�options
In�general,�the�high-voltage�battery�can�either�be�charged�using�alternating�current�(AC�charging)�or
direct�current�(DC�charging).�The�charging�options�of�the�high-voltage�battery�in�the�I01�are�generally
specified�by�the�equipment�for�charging�in�the�vehicle,�as�well�as�the�national-market�charging
infrastructure.�The�following�table�provides�an�overview�of�the�different�charging�options�in�various
countries.�The�charging�powers�always�relate�to�the�mains�power�and�not�the�charging�power�used�to
charge�the�high-voltage�battery.�The�charging�power�is�always�less�than�the�available�mains�power.
