3.2. BIB functional behaviour
3.2.1. General description
The BIB monitors all connected Li-ion batteries through the CAN bus. Whenever one or more
Li-ion batteries reports an alarm, or is missing on the bus, the BIB will disconnect the battery
(bank) from the DC bus to avoid misuse of the battery or to prevent an unsafe situation. The
alarms from the battery can differ with each battery type. Because the alarm is indicated to
the BIB as a general alarm, any Super-B battery with CANOpen communication can be used
in combination with the BIB. For alarms detected and signalled by the battery consult the
manual of the battery.
