AI Contract Overview

The U.S. Navy, through Naval Surface Warfare Center Crane, is seeking qualified sources capable of providing a regenerative battery cycler to replace legacy NHR 9200 systems, with the goal of testing and cycling large-scale lead-acid battery systems including VRLA chemistries used in mission-critical backup and maritime applications. The system must function as a bi-directional DC source and load, enabling regenerative discharge and recharge cycles with a minimum efficiency of 90%, and must support a voltage range of 1 to 40 volts and current ranges up to 3000 amps in both charge and discharge modes. The charger can deliver up to 40 kW while the discharge function must handle up to 60 kW, with facility input power requirements of 480 VAC, 3-phase, 60 Hz, 80A. The system must maintain precise voltage regulation of +/- 0.5% or better under all operating conditions and limit AC ripple on the DC bus to under 0.5% RMS. Air cooling is preferred and the system must be modular, supporting parallel channel scaling to expand current capacity. The equipment must integrate seamlessly with National Instruments CompactRIO controllers and LabVIEW software, utilizing IVI drivers for standard communication and control. It must support multiple operational modes including Constant Voltage, Constant Current, Constant Power, and pulsing. Hardware and software safety systems are mandatory and must include independent electromechanical contactors, a dual-channel external interlock loop, physical E-Stop buttons, reverse-polarity protection, soft-start pre-charge circuits, and programmable trip thresholds for over-voltage, under-voltage, over-current, and over-power conditions. A hardware watchdog timer must automatically shut down outputs and open isolation contactors if communication with the master controller is lost. The system must be capable of calibration to ISO/IEC 17025:2017 standards and include a minimum 12-month warranty covering parts, labor, and travel, with preventive maintenance and calibration services detailed. Responsive vendors must provide company capabilities, quality certifications, past government performance, and socioeconomic status, and must be registered in SAM.gov. No funding is currently available, and responses are for market research only; the government assumes no liability for costs incurred in submission. All correspondence must reference announcement number N0016426SNB96.
