Purpose
The Naval Surface Warfare Center Carderock Division (NSWCCD) is conducting a market survey of potential sources who may be interested in the development and manufacture of batteries and battery chargers for use on Naval Vessels. The resulting production units will need to be capable of being in production by 2011. This survey in no way binds the Government to offer contracts to responding companies. The information provided will assist NSWCCD in understanding available battery and battery charger technologies. Defense and commercial contractors, including small businesses, veteran-owned businesses, service-disabled veteran-owned businesses, HUBZone small businesses, and woman-owned small businesses are encouraged to participate. Respondents should demonstrate that they currently produce the above mentioned technologies in the power ranges specified for commercial or other military applications.
Description
This section provides a set of performance characteristics that meet the needs of a potential demonstration system, although consideration will be given to minor deviations from these requirements.
1. Operating Characteristics:
a. Battery below should be rated for a 10 deg F, worst case scenario
i. Voltage (VDC): 12 , 24 or otherii. Cold Cranking Amps (@0F): 500 - 2000iii. Capacity (Amp Hours 20Hr. Rating): 150 - 300 iv. Maintenance Freev. Life Expectancy (Years): 5 8 vi. Remote monitoring capability1. State of Charge indicator2. State of Health indicatorvii. Modular Design
b. Battery Charger
i. Taking into account ambient temperature, maintain charge for, but not overcharge, the above. Capable of charging the battery to 100% of rated charge Offline Charge to 85% of rated charge in less than 6 hoursii. Remote monitoring capability 1. RS2322. GPIB IEEE-488
2. Meet the following standard operating conditions and specifications:a. -30 to 160 deg Fb. 0-100% Humidity
Ensure proper operation (ability to perform all normal operations at maximum continuous performance ratings in accordance with the performance and safety requirements for each component/system without loss of lubrication and with no loss of liquids) under the following inclination conditions (conditions not considered additive)c. List: 15 degrees (static condition)d. Roll: 45 degrees and 30 degrees (dynamic condition)e. Trim (Normal): 5 degrees (static condition)f. Pitch: 15 degrees (dynamic condition)
Responses
Responses to this market survey should include supporting materials that discusses your companys competence, experience, and overall understanding of the requirements that NAVSEA has identified. The following information is requested (please indicate if the information is an estimate or actual)
1. Description of the component, its population base and applications, including an indication of the degree to which it is marinized and/or militarized.2. What is the development status of the component and what are the steps necessary to bring the units to a fully marinized and militarized standard, including EMI qualification (per MIL-STD-1399, MIL-STD-461), vibration qualification (per MIL-STD-167-1A - Type I).3. What are the non-recurring engineering costs and unit production cost estimates, identified individually for the component? Identify sensitivity of production cost to volume of sales (quantity discounts).4. What order quantity would offset the need for customer funding of the non-recurring engineering costs, including any breakpoints for levels of reduced non-recurring engineering cost.5. What is the estimated lifetime of each unit (battery/battery charger)? Please provide anticipated replenishment cycle for provided batteries as a function of full discharge/charge cycles.6. Are the batteries available in standard military form factors?7. Charger input power requirements?8. Ability to parallel multiple chargers?9. Can the charger be used with other batteries? Sensitivity to accommodate batteries of other chemistries?10. Provide the following functional relationships for your battery/charger designs:a. Estimated Cost per Ah ($/Ah)b. Estimated Weight per Ah (Ah/kg)c. Estimated Volume per Ah (Ah/m3)11. Estimated dimensions of components and weight for existing point designs in the operating range provided in the Description section.12. Identify any cooling air flow requirements.13. Identify State of Charge and Ah per load level for various temperature ranges in the operating envelop provided in the Operating Characteristics section.14. Minimum annual buys to sustain production and/or parts support.15. Are any of the technical constraints driving the ability to provide this component or adding risk to technical or schedule performance (what are the design drivers)?16. Mathematical model (i.e. Matlab/Simulink or other) of battery and associated components for use in trade-off analysis must include State of Charge and Ah relationships vs. time for different power levels and operating temperatures. 17. Installation Design Manual18. Describe any control system requirements. What type of communication protocol is/will/can be used? What data is/will/can be collected? What diagnostic and/or prognostic capabilities do the units have (state of charge or state of health indicator at a minimum)?
NSWCCD requests your responses by 05/15/2008. Information should be e-mailed to Chris.dafis@navy.mil) or mailed to Naval Surface Warfare Center, Attn: Chris Dafis, 5001 S. Broad Street, Building 87, Code 986, Philadelphia, PA. 19112 and labeled with the solicitation number and Battery & Battery Charger Survey. Questions can be submitted electronically to chris.dafis@navy.mil. Information provided will be treated as Business Sensitive and will not be shared outside of Government activities and agencies without the permission of the provider. All information shall be provided free of charge to the Government. NSWCCD may request further information regarding the capabilities of respondents to meet the requirements and may request a presentation and/or a site visit as deemed necessary.
