Integrated Back-up Battery System
Model: IBBS-12v-6ah
The Integrated Back-up Battery System, IBBS, is an electronic system
that combines a Lithium-Iron-Phosphate (Li-Fe-PO4) battery pack, a
charger and switching logic in one convenient package. The IBBS
provides an engineered solution to enable an endurance bus for critical
loads found in aircraft. It simplifies the wiring and installation of a source
of back-up power by integrating all of the key elements into a single
enclosure. The IBBS system provides back-up power to critical
electronic loads such as EFIS, GPS, Autopilots and engine monitor
systems.
Integral to the IBBS is a lithium-iron-phosphate battery pack and a
matched charging system to ensure the battery is properly charged and
maintained. The system also includes switching circuitry to provide a
stable source of output power during normal and emergency operations.
The IBBS system also provides signals to other equipment such as EFIS
systems to communicate the operating state of the main aircraft bus as
well as the state of the battery.
The IBBS system connects to the standard aircraft power bus and
provides an output to critical equipment that require back-up power.
Additionally, the IBBS system provides surge and sag protection for
connected equipment, allowing operation of critical equipment during
engine starting.
