Scoping an RFQ for Battery Formation and Capacity Grading Systems
Define channel count, cell formats, regeneration, cooling, and exclusions before requesting quotes for a battery formation and capacity grading system.
Start by deciding how many cells must be formed and graded per cycle, because channel count drives the channel architecture you should ask each supplier to quote. State whether the system must handle 18650, 21700, 26650 and 32650 cells, and whether format changeover is by fixture, tray or channel module; ask for the changeover method and time as a quoted option rather than assuming it is included.
Ask suppliers to describe the regenerative DC/AC power architecture and how regeneration behaves during formation and grading, plus the air-cooling arrangement and its heat load in your room. In the RFQ, separate base scope from options: cell holders, tray handling, software licenses, data export, calibration and spare channels. List exclusions explicitly, such as facility power, extraction, and acceptance-test cells.
For demonstrations and acceptance tests, specify sample cells, test profiles, throughput per shift, and the data records you will review. Ask each bidder to map its offer to your channel count, formats and cooling limits.
Before requesting a quote, confirm with the supplier which formats and channel counts are standard versus custom, what the quoted price includes, and which performance figures are guaranteed at acceptance.
