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.
