The�Electric�Vehicle�Supply�Equipment�can�either�be�integrated�in�the�charging�cable�or�be�an�element
of�a�fixed�charging�station�(also�called�"wallbox").�The�EVSE�establishes�the�connection�to�the�AC
voltage�network�and�serves�for�the�fulfilment�of�requirements�for�electrical�safety�when�charging�the
vehicle.�Communication�to�the�vehicle�can�also�be�set�up�via�the�pilot�line.�As�a�result,�it�is�possible
to�safely�start�the�charging�procedure�and�exchange�the�charging�parameters�(e.g.�maximum�current
level)�between�vehicle�and�EVSE.�Details�on�the�possible�versions,�structure�and�functioning�of�the
EVSE�are�described�in�one�of�the�following�chapters.
The�voltage�of�the�AC�voltage�network�can�be�in�the�range�of�110 V�to�240 V.�It�is�fed�to�the�vehicle
via�a�single-phase�supply.�From�the�AC�voltage�network�side,�in�theory�a�maximum�charging�power�of

= 240 V x 32 A = 7.7 kW�is�possible.
Many�of�the�components�mentioned�for�charging�the�I01�are�standardized�in�terms�of�their�structure
and�functions.�In�European�countries�IEC 61851�is�the�applicable�standard.�The�components�for
charging�the�I01�satisfy�charging�mode�2�(connection�to�standard�household�socket�with�additional
pilot�line)�and�charging�mode�3�(connection�to�fixed�wallbox�with�pilot�line).
The�standard�for�America�is�SAE J1772.�Charge�Level 1�and�2�are�comparable�to�charging
modes 2�and�3.�Most�components�for�charging�the�I01�only�satisfy�both�standards�with�one
technical�version.�A�national-market�or�standard-specific�version�is�required�for�Europe�and
America�only�by�the�"Electric�Vehicle�Supply�Equipment".
For�the�employees�in�BMW�Service�the�following�important�safety�rules�must�be�observed�in�relation�to
charging:
Refueling�the�vehicle�while�the�high-voltage�battery�is�charging�is�not�permitted�
When�the�charging�cable�is�inserted�do�not�initiate�a�refueling�procedure�and�keep�a�safe�distance�from
highly�flammable�materials.�Otherwise,�in�the�event�of�incorrect�connection�or�removal�of�the�charging
cable�there�is�a�risk�of�personal�injury�or�material�damage�by�burning�fuel�for�example.
While�the�I01�is�connected�to�the�AC�voltage�network�for�charging,�no�work�may�be�performed�at�the
high-voltage�system.
During�the�charging�procedure�the�electric�coolant�pump�and�the�electric�fan�can�be�switched�on
automatically�for�cooling�the�power�electronics.�This�is�why�no�work�can�be�performed�at�the�cooling
system�of�the�electric�motor�and�at�the�electric�fan�when�a�charging�cable�is�connected�to�the�I01.
