REV 1.6 © 2019 TCW Technologies, LLC.1Integrated Back-up Battery SystemModel: IBBS-12v-6ahThe Integrated Back-up Battery System, IBBS, is an electronic systemthat combines a Lithium-Iron-Phosphate (Li-Fe-PO4) battery pack, acharger and switching logic in one convenient package. The IBBSprovides an engineered solution to enable an endurance bus for criticalloads found in aircraft. It simplifies the wiring and installation of a sourceof back-up power by integrating all of the key elements into a singleenclosure. The IBBS system provides back-up power to criticalelectronic loads such as EFIS, GPS, Autopilots and engine monitorsystems.Integral to the IBBS is a lithium-iron-phosphate battery pack and amatched charging system to ensure the battery is properly charged andmaintained. The system also includes switching circuitry to provide astable source of output power during normal and emergency operations.The IBBS system also provides signals to other equipment such as EFISsystems to communicate the operating state of the main aircraft bus aswell as the state of the battery.The IBBS system connects to the standard aircraft power bus andprovides an output to critical equipment that require back-up power.Additionally, the IBBS system provides surge and sag protection forconnected equipment, allowing operation of critical equipment duringengine starting.
