Caution!
High voltages may be present in the Li-ion battery system. Access to the battery
system is only allowed by trained professionals!
Safety components selection and design (fuses, cable thickness etc.) should be done
following safety guidelines especially for systems > 120Vdc. Super B is not responsible of the
overall system integration.
!
Warning!
Always take safety precautions when working on battery systems.
In certain applications, the below components / functionalities might be necessary:
1. Ground Fault Detection device – required for ungrounded systems.
2. Emergency stop – depends on the user preference but can also be a safety requirement.
3. EMC Filter – the need should always be evaluated especially in installations which include high
frequency drives.
4. Manual battery switch – is necessary during maintenance, to isolate the battery voltage from the rest
of the system during human intervention.
If the BCI is used with a Li-ion battery bank that consists of 4 or less Li-ion batteries in series
(48V or less) the battery supply power input of the BCI and its functionality can be used. If
the BCI is used with a Li-ion battery bank with a higher voltage it needs to be powered by an
external power supply. This supply can be between 15 and 60Vdc, typical 24 Vdc .
Note: For systems ≤ 60Vdc, Super B offers a complete solution: the Battery Interface Box
(BIB).
The below will describe in detail the differences and show examples of complete installations
for each of those systems.
