5 Overall Integration Requirements of e-
GoKart System Components into the
Superior Vehicle Context
5.1 Electrical Integration
For the electrical integration the BOSCH MOTORSPORT e-GoKart System components
have to be connected via dedicated wiring harness.
# During the electrical integration following order of integration steps shall be considered:
1.
Connection B+ and B- cable to the Power Unit PU 5-10.
2.
Connection of communication plug to the Power Unit PU 5-10.
3.
Connection of B+ and B- cable to the Charger Energy Storage CH 5-1.2.
4.
Connection of communication plug to the Charger Energy Storage CH 5-1.2.
5.
Connection of the AC connector to the Charger Energy Storage CH 5-1.2.
6.
Connection of B+ and B- cable to the Energy Storage ES 5-2.4.
# Assembly or disassembly of the cables is only permitted without applied voltage.
# The wiring harness routing of communication wiring shall consider that mechanical
loads to the BOSCH MOTORSPORT e-GoKart System component connector pins and to
the connector sealing are avoided while mounting as well as in use.
# All 48 V components shall be connected to a distribution point. This might be traction
net power distribution unit (PDU).
# Usage of two cable lugs on top of each other at the terminals of the Energy Storage ES
5-2.4 is not allowed. Parallel Energy Storages ES 5-2.4 must be connected via dedicated
rails or comparable solutions.
There is one common ground point of 48 V and 12 V ground located inside the DC/DC
converter.
# No additional ground connection is allowed.
# Maximum ground mismatch on 12 V ground net shall not exceed ±1 V.
# For reasons of electromagnetic capability the DC cable length between the Charger En-
ergy Storage CH 5-1.2 and the Energy Storages ES 5-2.4 shall be ≤3 m.
# The housing of the VCU MS 40 shall be electrically isolated to the conductive vehicle
chassis, in order to prevent electronic disturbance of the system and to increase the ro-
bustness of the system in the case of failures, e.g. short circuits in the cable harness.
5.2 Mechanical Integration
All 48 V components, except for the DC/DC converter have screw connections for eyelet
connectors for the connection to the 48 V net. The DC/DC converter provides a dedicated
socket.
# Screws to connect the wiring harness to the BOSCH MOTORSPORT e-GoKart System are
in the responsibility of the CUSTOMER. BOSCH MOTORSPORT will propose appropriate
screw descriptions based on the BOSCH MOTORSPORT e-GoKart System component in-
terfaces.
