2. Introduction
2.1. Product description
The Battery Interface Box (BIB) is a device capable to connect and disconnect a battery
or a battery bank to a load / charger (DC bus) with the intent to protect the Li-ion battery or
battery bank against improper use. The BIB communicates with the battery’s BMS (Battery
management system) to request to the batteries if they are operable and used within their
limits.
2.2. Intended use
The Battery Interface Box (BIB) is intended to use as a disconnect device for protecting
batteries against misuse. Potential applications of the BIB include: off grid power supply,
marine power supply, industrial power supply and (renewable) energy storage. The BIB may
not be used in medical and aviation related applications.

!
Warning! A warning indicates severe damage to the user and/or product may occur when a
procedure is not carried out as described.
!
Caution! A caution sign indicates problems may occur if a procedure is not carried out as
described. It may also serve as a reminder to the user.
3. Product specications
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 congured 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,

7
Be in charge. Super B.
monitoring and control of the battery bank using the battery monitor software can only be
done on the master port (J1).
• Three status LED’s to indicate the status of the battery (bank).
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.
3.2.2. BIB states
The BIB different states, are listed in table 2 below.

Description
ON On Off Bank is connected to the DC-bus
OFF Off Off Bank is disconnected from the DC-bus
Pre-charge Off On Bank is pre-charging the DC-bus
Error Off Off An error occurred, see below
Shutdown Off Off BIB is in power down mode, see below
Undervoltage
reboot On Off BIB is turned on again after an undervoltage shutdown
Table 2. BIB States
3.2.2.1 ON state
The BIB is in or can be set to the ON state when there are no active errors. In this state the
main relay is enabled, the battery bank is connected to the DC bus. The BIB can be set to ON
state using the battery monitor, or automatically when the auto-on feature is enabled. The
BIB can only reach the ON state via the pre-charge state rst.

8
3.2.2.2 OFF state
The BIB can be set in OFF state by the battery monitor software. In this state the main relay is
disabled, the battery bank is disconnected from the DC bus.
3.2.2.3 Pre-charge state
A battery bank system with a large capacitive load can be exposed to high electric current
during initial turn-on. This current, if not limited, can cause considerable stress or damage to
the system components. Pre-charging is implemented to increase the lifespan of electronic
components and increase reliability of the battery bank. In the pre-charge state the main
relay is disabled and the pre-charge relay is enabled. The main relay will only be enabled
when the voltage across the main relay is less than 1.25V times the number of batteries in
series. For example, for an 48V system (four batteries in series) the voltage across the relay
should be less than 5V. The BIB will go into the ON state 1 seconds after the main relay has
been enabled. Table 3 shows the ohmic value of the pre-charge circuit.
!
Caution! If the system draws more current than the pre-charge current the BIB will not be
able to engage the main relay since it cannot properly pre-charge the system.
!
Caution! It is important that the load is not engaged before the BIB is done pre-charging.
3.2.2.4 Error state
When the BIB is in error the following may have occurred:
The number of batteries that respond to a present request does not match the number of
batteries congured in the BIB. If the error is resolved the BIB goes to OFF state or when
auto on is enabled to ON state.
One or more of the batteries reports an alarm. When the alarm of the battery is cleared the
BIB goes to OFF state or ON if the auto on feature is enabled. Depending on which type of
alarm the battery signalled, this alarm can be cleared automatically. Refer to the battery
manual for the type of alarm and how to resolve it.
3.2.2.5 Shutdown state
In this state the main relay and the pre-charge relay are disabled, the BIB doesn’t take any
power from the battery bank and will turn off. However, if there is power on the DC bus the
BIB will stay on and takes only power from the DC-bus.
3.2.2.6 Undervoltage shutdown
When a battery indicates an undervoltage, the BIB will go into the shutdown state. The BIB
can be turned on again by using the on/off button. When this happens, the BIB will go into the
undervoltage reboot state.

9
Be in charge. Super B.
3.2.2.7 Undervoltage reboot state
In the undervoltage reboot state the battery (bank) will be connected to the DC-bus but
discharging is limited regarding capacity to 0.1 Ah.
This allows chargers that need to see a battery, to start charging. The BIB will now allow the
battery bank to be discharged with 0.1Ah before it will go to shutdown state again. When the
battery bank is charged with 1Ah the BIB will switch to the ON state. The BIB will also go to
the shutdown state after 10 minutes spend in the undervoltage reboot state, this implies that
the battery bank should be charged with at least 1Ah to avoid unnecessary shutdown
3.3. BIB control functions
3.3.1. Auto-on
The auto-on function automatically sets the BIB into ON state when the BIB is powered
up. Also if a battery alarm has occurred and this alarm is cleared (see 3.2.2.4) the BIB
automatically goes to the ON state if the auto-on function is enabled. The battery monitor
software can be used to control the auto-on function.
3.3.2. SoC shutdown
The SoC shutdown is a function that makes it possible to put the BIB in shutdown state at
a certain level of state of charge. The level can be set by the user and this function can be
enable or disabled. By default, it is disabled. Control of this function is done by the battery
monitor software.
When the battery bank reaches the SOC shutdown level, the BIB will go into shutdown state.
The shutdown is activated only with descending SoC level. If the BIB is in shutdown state it
can be turned on again by using the on/off button. When the BIB is turned on again, it will
not shutdown on SOC again unless the SoC of the battery (bank) is charged 1% above the
shutdown level. This re-enables this functionality. Once the SoC shutdown has occurred and
the BIB is turned on again and no charge is applied, the battery bank can be discharged until
an undervoltage shutdown occurs.
3.3.3. Reset button
Some alarm types of the battery can only be cleared by a reset. To perform a reset, press the
reset button on the BIB or use the battery monitor.

Be in charge. Super B.
The BIB must be connected to the male to male cable to the rst splitter and from there the
rest of the battery bank can be connected. For further information about the CAN network,
read the manual of the batteries that will be connected to the BIB.
4.6.2. CAN Bus network topology
The CAN Bus must be used in a bus network topology. Do not use a ring- or star topology. The
maximum CAN bus length is limited by the bitrate. The Li-ion battery has a default bitrate of 250kbps
(See table 11) .
Bit rate Bus length (L) Max. stub length (S) Accumulated stub
length
250 kbps 250 m 11 m 55 m
Table 11. CAN bus speed
4.6.3. Termination Resistors
The CAN bus requires termination at the two outer ends of the bus. It is advised to use the
termination resistors (see paragraph 3.7) at the end nodes to prevent reections on the line.
The value of this resistor should be 120 ohm.
4.6.4. Installation of the CAN power cable
A 12V system always needs a CAN power cable. In a 24V or 48V system up to sixteen
batteries the BIB provides power for the CAN bus. In any 24V or 48V system with more than
sixteen batteries the CAN bus must be powered externally, using a CAN power cable. The
CAN bus power should be at least 10V and should not exceed 30V! Therefore, in any 12V or
24V system the CAN bus can be powered directly by the system power.
!
Warning! When using a 48V system with more than sixteen batteries, please contact Super-b
to discuss the installation of the system.
There are two possible ways to connect the CAN power cable to the BIB and Li-ion batteries:
1. The rst option is to connect the (+) terminal (red wire) of the CAN power cable to the load side of the
main relay. There is a disadvantage to this setup; when the main relay opens the CAN power is cut-off.
This causes the loss of CAN communication between the batteries and the BIB. The load side of the
BIB must be powered to have CAN communication while the main relay is OFF. Without CAN
communication the BIB cannot turn on.

20
Figure 8. Connecting the CAN power cable to the load side of the main relay.
2. The second option is to connect the (+) terminal of the CAN power cable to the batteries side of the
main relay. In this case the CAN communication is always available. There is a disadvantage to this
setup; the CAN bus is always powered,therefore; it will drain the Li-ion batteries slightly even when
the main relay is turned off. When using this setup, Li-ion batteries can be deeply discharged.
Make sure that the Li-ion batteries will be charged immediately when they are empty.
4.7. Disconnecting the BIB
The following steps must be taken to disconnect the BIB.
1. Turn off the BIB using the ON/OFF push button.
2. Disconnect the + power cable from the battery bank.
3. Disconnect the Load + from the BIB.
4. Disconnect the positive (+) wire from the BT+ terminal of the BIB.
5. Disconnect the BT- wire from the (-) terminal of the battery bank.
6. Disconnect the CAN cables from the BIB.
