3.1. Product features
The BIB ensures the following functions:
•
Collecting the status and alarm messages of all the Li-ion batteries connected. In case of an
alarm in one of the batteries, the BIB will disconnect the battery (bank) by opening the main
relay.
•
Scanning the CAN bus to see if all the batteries it expects are present. In case of a missing
battery, the BIB will disconnect the battery (bank) by opening the main relay.
•
Collecting information of all Li-ion batteries in the battery bank and presenting it as one
battery.
•
Programmable power down on user adjustable battery (bank) SoC level.
•
Programmable Auto-On function.
•
Up to sixteen batteries can be connected to the BIB without external CAN power. (With the
12V BIB versions, external CAN power is always necessary.)
•
Up to 100 Li-ion batteries can be connected to the BIB with use of external CAN power.
•
Pre-charge as startup sequence to prevent inrush currents.
•
The BIB is a standalone device.
•
The BIB can be configured using a CAN-USB converter and the battery monitor software.
The BIB mainly includes the following:
•
A main relay to connect or disconnect the Li-ion batteries from the DC bus.
•
A pre-charge circuit including a relay , a resistor, and a thermostat for protection.
•
Two CAN communication ports:
•
The master port indicated by J1. This port is for the Li-ion batteries. The communication
protocol used is CANOpen.
•
The slave port indicated by J2. This port is to communicate with an external network. This
port can also be used for other CAN protocols.
All the battery (bank) values can be monitored on both ports. The battery bank can also be
controlled via both ports. If the slave port (J2) is used for another protocol than CANOpen,
