Format D Battery Module

1Reliable and continuous power to submarine electronics is essential for mission execution and for the safe operation of the ship. Digital electronics cannot continue operation through even very short power outages cause by bus transfer devices that have historically been sufficient for analog combat systems. The restart and reload that a digital system must execute after a short power interruption and the subsequent confusion that results while operators recover the tactical picture are a hazard to the ship. A central, auctioneered DC power system has been proposed to provide uninterruptable power. This system is heavy, complex, and potentially unreliable. An alternative to the DC system is proposed. High-discharge rate battery technology exists that can support the operation of the combat system through a bus shift transient. Other battery system support only memory; this concept maintains full operation. The battery proposed is manufactured in a shape that allows it to fit unused Format D slots in the Common Electronic Equipment Enclosure used by the AN/BSY-1 and AN/BSY-2. The work proposed establishes the feasibility of the battery unit and demonstrates its operation in a simulated combat system electronic drawer.
