Overall Integration Requirements of e-GoKart System Components into the Superior Vehicle Context | 5
# If the unpacked VCU MS 40 was dropped, it is strongly recommended not to use the
VCU MS 40 further, because latent damages may affect functions or reliability.
# The VCU MS 40 shall have reached normal room temperature after the transport before
another use, particularly of flashing the software.
# Dew shall be avoided.
# Even though the VCU MS 40 is designed to fulfill IP6K9K, the VCU MS 40 shall not be
permanently exposed to water (no submersion).
# It is recommended to isolate the VCU MS 40 housing from the vehicle chassis electric-
ally. This supports higher robustness of the system in the case of failures, e.g. short circuits
in the cable harness.
Power dissipation is conducted over cooling benches.
# The VCU MS 40 shall be fixed to the wiring harness box of the vehicle so that the ambi-
ent conditions specified in this document are complied with.
# The VCU MS 40 shall be mounted at 4 mounting points in the vehicle.
# The mounting surface between all 4 mounting points shall be even with maximum dif-
ference in parallelism of 0.5.
# There shall be a minimum distance of 50 mm from the VCU MS 40 to the outer surface
of the vehicle (vehicle body). This is to ensure, that no external mobile transmitter (e.g. in
a cellular phone) can disturb the system. In case that there is an internal mobile transmit-
ter installed (e.g. in vehicle sharing concepts), the distance shall also be considered.
# The wiring harness shall be mechanically fixed next to the VCU MS 40 (maximum dis-
tance 150 mm) such that an impact due to phase-shifted excitation of the wiring harness
compared to the VCU MS 40 is avoided (e.g. at the VCU MS 40 screw-on plate).
# Relative movement between the wiring harness and the VCU MS 40 shall be minimized.
Tension and pressure force on the connector caused by the wiring harness is not permiss-
ible.
# The wiring harness shall not rub on neighboring parts.
# Potential loads onto cover and/or bottom of the VCU MS 40 housing resulting from the
mounting position in the vehicle shall be agreed on between the CUSTOMER and BOSCH
MOTORSPORT.
# Impact of chemicals (e.g. oils, gasoline, detergents for cleaning, brake fluid, battery acid,
etc.) should be minimized. Misuse of chemicals shall be considered.
5.3.2 Energy Storage ES 5-2.4
BOSCH MOTORSPORT provides a standard solution for mounting the Energy Storage ES
5-2.4 in the vehicle frame.
