MH-60R Sonar NiCad Battery Reliability Improvement Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-018 Topic Title: MH-60R Sonar NiCad Battery Reliability Improvement Proposal No.: N101-018-0352 Firm: CornerTurn LLC 423 Jenks Circle Suite 101 Corona, California 92880 Contact: Michael Cox Phone: (951) 256-4208 Web Site: http://www.cornerturn.com Abstract: This proposed effort will modify the NiCd Battery Pack used in the MH-60R AQS-22 Transducer to insure that Battery Pack failures are not the reason for excessive Transducer replacements during the operational life of the AQS-22 Sonar. The design strategy is to add monitoring circuitry to the system that monitors and controls the charging and discharging of each individual cell within the battery pack without impacting the present interface to the existing Transducer electronics. These modifications will extend the number of charge/discharge cycles achievable with the NiCd Battery Pack to the levels achievable with properly monitored, individual NiCd battery cells. Benefits: Extending the operational life of the AQS-22 Transducer NiCd Battery Pack will insure that Battery Pack failures will not be the reason for excessive Transducer replacements. Even as little as a 3-month improvement in the average time between Transducer replacements will save the MH-60R program tens of millions of dollars over the operational life of the MH-60R fleet. This technology could effectively be applied to any system using NiCd, NiMH or Lithium battery packs that also have a high cost of component replacement. This includes other military systems, remote sensor systems (terrestrial or satellite), hi-reliability critical systems where cost is also measured in system downtime, or systems where the replacement process is difficult (drilling rigs, nuclear reactors, arctic exploration equipment or extended underwater equipment).
