Innovative Manufacturing Processes

Yardney, Inc. proposes a program to develop, test and deliver high-performance, prismatic Lithium-ion batteries, to demonstrate the manufacturing capability and reliability of such batteries for space applications. The proposed battery will include asophisticated microprocessor-based intelligent battery management system. The electronics will provide full cell monitoring and balancing during charge, protection circuitry against over or under voltage, current and temperature, and Battery State ofCharge and State of Health calculation, monitoring and reporting. The modular design of the proposed electronics package makes it easily adaptable to multiple battery configurations, adding and removing capabilities as dictated by the program and able toeasily support much larger and higher voltage battery systems. Further, the proprietary control algorithm within the system efficiently charges the battery using any suitable current-limited power source, thereby allowing the seamless integration of theLithium-ion battery into most existing applications without costly electronics redesign. The 28V, 30Ah battery proposed mimics that already successfully developed and qualified for the MSP01 Mars Lander Program, as well as the battery intended for use inthe XSS-11 satellite system. This cross-utilization of the proven cell technology will allow for side-by-side comparisons of performance parameters measured on the ground with those found in launched systems. Manufacturability, reproducibility, reliabilityand affordability of space-rated Lithium-ion batteries will be demonstrated through this program. Demonstrate manufacturability, reliability and affordability of Lithium-ion battery systems for commercial and military aerospace applications. Enhancementof battery service and performance utilizing adaptable, modular electronics control system.
