Executive summary
A buyer-side FAT script covering capacity, protection thresholds, communication registers and packing before shipment release.
What FAT should prove before payment milestones
FAT is not a marketing demo. It should prove the approved drawing revision, cell lot traceability, BMS firmware hash, and measured capacity against the purchase order. Agree sample size in writing—full 100% testing is rare; AQL sampling is common for large lots.
Electrical and protocol checks
Validate over-charge, over-discharge, over-current and short-circuit responses with calibrated loads. Read RS485 or CAN registers for voltage, current, SOC and alarm codes. Photograph connector polarity and serial labels for the quality archive.
Packing and document pack
Confirm UN38.3 report number on the carton, MSDS version, and that spare connectors match the packing list. Reject lots when firmware differs from the signed prototype without a change notice.
Buyer checklist
Put temperature, load profile and protocol into the RFQ.
Request certificates and traceability for the exact PO model.
Pilot before fleet rollout.
FAQ
Who should attend FAT?
Ideally the buyer’s electrical engineer plus a logistics contact. Remote video FAT works if meters and register screens are readable and recordings are archived.
