- Description
- This is amendment No. 1 to the combined synopsis/solicitation entitled CandidateLi-ion Cell Designs for the International Space Station Battery which was posted on March05, 2009. You are notified that the following changes are made: 1. This amendment hereby establishes a maximum 25 page limitation for supportingtechnical rationale.2. This amendment answers questions that have been submitted. See below.Question: Are there any page or formatting limitations to the proposal? Answer: This amendment establishes a maximum 25 page limitation for supporting technicalrationale.Question: Do you want the quote to include one (1), ten or twenty (20) single-cell testfixture clamps? The RFQ appears to ask for 20, but that does not seem to make sense,unless the requirement is not well understood. (Cells from the 10 cell fixture will alsobe used in single cell fixtures, for example) Answer: If the cell design proposed requires fixturing to perform during NASA'sperformance acceptance and LEO life tests, then one (1) ten-cell fixture and twenty (20)single cell fixtures are required to be delivered with the 20 single cells as stated inthe RFQ. Also, if necessary to ensure consistent performance, provide assemblyinstructions for the fixtures.Question: Do you want this to be a Firm Fixed Price quote?Answer: Yes.Question: The 120V ISS Li-ion Battery ORU Requirements list: Operating Voltage Window Useful discharge/charge capacity shall be delivered/acquired between 76 and 126 Vdc. For typical Li-ion cell voltage ranges, the high end of 126 VDC would not have beenexpected to equate to a low end as low as 76. If conservative (for maximum cycle-life)cell EoCV of 3.95 V is defined, then the 126 V battery EoCV would lead to a 32-cellbattery. Then a cell-level 3.0V EoDV would equate to a battery-level EoDV of 96 V, wellabove 76V. Please confirm the Operating Voltage Window lower limit value. Answer: The 76 to 126 Vdc window is the current one used by the incumbent Ni-H2 system.Your proposed lithium-ion concept can utilize a narrower window and still meet therequirements of the RFQ.Question: The current ISS Battery ORU envelope includes a designated Electronics zone,per SOW Figure 1, which is presumably based on the current legacy Ni-H2 batteryconfiguration. If the Offeror has a complete integrated Li-ion battery design, includingelectronics, which fits within the overall ORU envelope, including thecurrently-designated electronics zone, must the existing design be deconstructed toseparate the cells and electronics, or can the entire ORU envelope (except for the twosmaller keep-out zones), be used? The potential benefits of maximizing the ISS/CEVCommonality goal by using an already space-qualified CEV battery (or very closederivative thereof), which could be mounted as-is directly into the ISS ORU and connectedto ORU mechanical and electrical interfaces, would be very compelling. These benefitswould seem to far outweigh any potential value of retaining the legacy electronics zone,unless it is also used for non-battery purposes. The 2 keep-out zones could, in any case,still be preserved. Please confirm that we may include ISS ORU design options that makeuse of portions of the current Electronics zone. Answer: For the purpose of your cell design selection for your quotation, NASA recommendsthat you propose a battery design concept that meets the required keep out zonesspecified in the RFQ. Trading battery concepts that don't meet the RFQ requirements isbeyond the current scope of NASA cell evaluation effort. The due date for responses is not extended.Documents related to this procurement will be available over the Internet. Thesedocuments will reside on a World Wide Web (WWW) server, which may be accessed using a WWWbrowser application. The Internet site, or URL, for the NASA/JSC Business Opportunitieshome page is http://prod.nais.nasa.gov/cgi-bin/eps/bizops.cgi?gr=D&pin=73 Offerors are responsible for monitoring this site for the release of the solicitation andany amendments. Potential offerors are responsible for downloading their own copy ofthe solicitation and amendments (if any).
