REGENERATIVE BATTERY CYCLER

MARKET SURVEY - SOURCES SOUGHT SYNOPSIS: The Government is issuing this RFl/sources sought announcement as part of market survey to identify qualified sources capable of providing a regenerative battery cycler to replace NHR 9200 cyclers. This equipment will be utilized to test, cycle, and evaluate large-scale lead-acid battery systems to include VRLA chemistries. used in mission-critical facility backup and maritime applications. To enable seamless regenerative discharge and recharge cycles, the equipment must function as a bi-directional DC source and load. The Contractor shall provide a turnkey testing system, including all necessary power hardware, control software, environmental sensor integration, and safety interlocks required to safely cycle high-capacity lead-acid battery banks. Interested sources must demonstrate the capability to provide a system that meets or exceeds the following specifications: Electrical & Performance Specifications Parameter Required Specification Voltage Range 1 - 40V Current Range 0 - 3000A (Charge and Discharge) Power Range (Charge) 0 - 40 kW Power Range (Discharge) 0 - 60 kW Facility Input Power 480 VAC, 3-Phase, 60 Hz, 80A Cooling Air Cooling is preferred Regenerative Power Efficiency Regenerative discharge capabilities of at least 90% AC Ripple Limitation AC ripple voltage imposed on the DC bus must be less than 0.5% RMS of the float voltage Voltage Regulation Precision Maintain a steady-state DC output voltage regulation of +/- 0.5% (or tighter) across all operating ranges, independent of line voltage fluctuations or rapid load transitions. Design & Integration Capabilities Feature Requirement System Architecture Bi-directional DC source/load and battery cycling equipment utilizing a modular design. Parallel Channel Scaling Capable of paralleling multiple channels to multiply the current capacity Control Modes System must support Constant Voltage (CV), Constant Current (CC), and Constant Power (CP) along with pulsing operational modes. Hardware Integration Must be fully compatible with National Instruments (NI) CompactRIO (cRIO) controllers and data acquisition (DAQ) systems. Software Integration Must be LabVIEW compatible and support standard integration utilizing Interchangeable Virtual Instrument (IVI) drivers. The system must incorporate multiple independent layers of hardware and software safety controls to protect personnel, facility infrastructure, and the Unit Under Test (UUT). The system must meet or exceed the following safety capabilities: Safety Feature Requirement Physical Isolation Must feature internal, independent electromechanical safety contactors on the DC output channels. Hardware Interlocks Must include a dedicated, dual-channel external wired interlock loop for integration with thermal chambers or external safety gates, alongside a front-mounted physical Emergency Stop (E-Stop) Interlocks. UUT Protection Circuits Must feature integrated reverse-polarity checking and a soft-start pre-charge circuit to prevent in-rush current surges upon battery connection. Programmable Protection Software and firmware must allow users to define strict, fast-acting trip thresholds for Over-Voltage (OV), Under-Voltage (UV), Over-Current (OC), and Over-Power (OP). Communication Fail-Safe Must feature a programmable hardware watchdog timer that automatically shuts down the outputs and opens isolation contactors if communications with the master controller (e.g., cRIO) are interrupted. Warranty and Maintenance: Support Category Requirement Standard Warranty Provide details on the standard OEM warranty (minimum 12 months preferred), including coverage details (parts, labor, and travel) and return-to-factory vs. on-site repair terms. Preventive Maintenance Describe available preventive maintenance agreements (PMAs), including the recommended frequency of on-site inspections, fan/filter replacements, and thermal checks. Calibration Services Detail the requirements and procedures for system calibration. The system must be capable of being calibrated to ISO/IEC 17025:2017 standards. Specify if calibration can be performed on-site or if the unit must be returned to the manufacturer. Technical Support Provide information on available technical support structures, including guaranteed response times (e.g., 24/48-hour response), availability of remote diagnostics, and software update access. The technical specifications listed represent the Government's target operational baseline. If interested sources cannot meet these exact thresholds (e.g., specific voltage, current, or power ranges), they are requested to submit their standard commercial capabilities, highlighting where their system deviates, and propose alternative configurations that could meet the overall mission objective of replacing the NHR 9200-60 with equivalent or upgraded equipment. Responses should include the following: Include your companies technical and manufacturing capabilities and quality certifications held. Lastly, please provide a history of your company and past performance on Government contracts if any. This submission may be in the form of product literature, operating instructions, and/or supplemental technical documentation that define the item(s) and associated hardware. Potential sources should provide any delivery, shipping or warranty information. Responses from Small and Small Disadvantaged Business firms are highly encouraged. Firms responding should indicate if they are a small business, a socially and economically disadvantaged business, 8(a) firms, historically black colleges or universities, and minority institutions. Responses to the RFI shall include the following: Submitter's Name Street Address, City, State, NINE-Digit zip code Point of Contact (POC) Cage Code Size and Socioeconomic Status POC Telephone and facsimile numbers Announcement Number: N0016426SNB96 Contractors must be properly registered in the Government System for Award Management database (SAM). Offerors may obtain information on SAM registration and annual confirmation requirements by calling 1-866-606-8220, or via the Internet at www.sam.gov. At the current time, NO FUNDING IS AVAILABLE for contractual efforts.
