Installation�location�of�the�EDME
Active�cooling�of�the�EDME�is�not�intended�as�at�the�installation�location�there�is�a�significantly�lower
temperature�level�as�a�result�of�no�combustion�engine�in�the�I01.�The�EDME�control�unit�also�has
considerably�fewer�output�stages�in�comparison�to�an�engine�control�for�combustion�engines�and
therefore�less�heat�loss�occurs�in�the�control�unit�itself.
The�electrical�interfaces�of�the�EDME�control�unit�are�described�in�the�list�below:
• 12 V�voltage�supply�of�the�EDME�control�unit�(terminal�30B,�ground�connection)
• Accelerator�pedal�module�with�two�hall-effect�sensors:�Supply�voltage,�ground�and�sensor
output�signals�with�output�voltage�range�of�0 V�to 2.5 V�and�0 V to 5.0 V
• Brake�light�switch�and�brake�light�test�switch:�inverse,�redundant�signals�(actuated/not
actuated),�supply�via�terminal�R
• Local�interconnect�network�bus:�Reading�of�the�signals�from�the�IBS�and�control�of�the�electric
coolant�pump�(cooling�circuit�between�electrical�machine/electrical�machine�electronics�and
charging�electronics)
• Control�of�the�electric�fan:�The�power�of�the�electric�fan�for�cooling�the�cooling�package�at
the�front�can�be�controlled�via�a�pulse-width�modulated�signal�by�the�EDME.�For�emergency
operation�there�is�a�relay�with�which�the�electric�fan�can�be�switched�on�at�full�power�by�the
EDME.
• Body�Domain�Controller�BDC�(start�enable)
• PT-CAN�(no�terminating�resistor�in�the�EDME)
• PT-CAN2�(no�terminating�resistor�in�the�EDME)
• FlexRay�(terminating�resistor�in�the�EDME).
The�functions�of�the�drive�control�are�already�described�in�detail�in�the�chapter�"Functions".�The
following�list�summarizes�again�the�functions�which�the�EDME�control�unit�calculates�and�performs:
