6.1.5.�Electric�Vehicle�Supply�Equipment
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�so-called�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.�The�EVSE
can�either�be�integrated�in�the�charging�cable�(mobile�solution)�or�be�an�element�of�a�fixed�charging
station�(also�called�"wallbox").
In�both�cases�the�EVSE�contains�the�following�subcomponents:
•
Earth�leakage�circuit�breaker�(FI)
•
Display�whether�the�AC�voltage�network�is�connected�and�available
•
Electronic�disconnect�switch�for�phase�(L1)�and�neutral�conductor�(N)
•
Electronic�switching�for�generating�the�pilot�signal
•
Continuous�protective�earth�(PE).
Mobile�solution
The�version�integrated�in�the�charging�cable�is�also�called�"In-Cable�box"�and�is�designed�for
mobile�use.�The�volume�and�weight�of�this�solution�is�low�and�the�charging�and�EVSE�can�be�easily
transported�in�the�vehicle.
