Electrical interface, harness requirements
A cable harness between the Charger Energy Storage CH 5-1.2 and the Energy Storages
ES 5-2.4 is included in the scope of delivery. This harness is divided in two portions:
1.
Charger Energy Storage CH 5-1.2 - Connector
2.
Connector - Battery Terminals
On the vehicle side a harness which is compatible with section 2) for all installable packs
shall be used
The communication between the system components is realized via CAN bus. There is no
need for an external control.
# The communication lines shall be realized in accordance with ISO 11898 (impedance,
shielding, twisted pair etc.)
The proposed setup does not require additional grounding. Any additional grounding
might lead to hazards or malfunction and is subject to agreement and validation with
BOSCH MOTORSPORT.
Thermal integration
The Charger Energy Storage CH 5-1.2 does not require any additional active cooling. An
integrated fan operates at higher temperatures. If fan operation is impaired, charge per-
formance may be limited but can continue. If mounted in a rack, appropriate heat convec-
tion flow shall be ensured.
In order to ensure sufficient heat dissipation from the housing, the Charger Energy Stor-
age CH 5-1.2 shall be splash water and dirt protected.
Heat radiation of adjacent components should not exceed the maximum permissible com-
ponent temperatures as specified in the system TCD.
Installation environment must not constrain air circulation.
The housing temperature of the Charger Energy Storage CH 5-1.2 can reach temperatures
above 60°C
Mechanical integration and Harness requirements
All components shall be protected against drop and moving.
