01 · QUESTION / INTENT
Give suppliers enough boundary conditions to quote the same problem and return comparable evidence.
02 · DIRECT ANSWER
An engineering-ready RFQ states application, system voltage/energy/power, duty cycle, SOC and temperature range, mechanical envelope, cooling and compression concept, pack/BMS ownership, life target, qualification plan, document list, samples, volume ramp, destination, Incoterm, RFQ date and SOP/COD. It also marks unknowns and assigns who will close them.
03 · DECISION TABLE
| Decision factor | Decision direction | Confirm before approval |
|---|---|---|
| Technical boundary | Describe the problem before naming a preferred model. | Duty, environment, interfaces and acceptance criteria. |
| Commercial boundary | Separate sample, pilot and SOP volumes. | Forecast, firm quantity, delivery schedule, currency and Incoterm. |
| Evidence boundary | Ask for a model-specific, dated deliverable register. | Document scope, revision, owner, due date and confidentiality. |
04 · ENGINEERING EXPLANATION
Use one requirement matrix with units, nominal/limit values, verification method and owner. Suppliers should answer comply/deviation/open with evidence references, not rewrite the requirement in marketing language.
05 · APPLICATION / MARKET MAPPING
BESS RFQs emphasise degradation and bankability; vehicle RFQs emphasise packaging, power, charging and validation; industrial and marine RFQs add vibration, environmental and certification pathways.
06 · EVIDENCE AND TEST CONDITIONS
- Requirement-compliance matrix and controlled deliverable list.
- Quotation assumptions, exclusions and open-item register.

07 · RISKS / NOT SUITABLE WHEN
- A model-and-quantity-only RFQ produces non-comparable quotes and hidden redesign.
- Do not force invented values; mark unknowns and request engineering support.
08 · FAQ
Can the RFQ start before pack design?
Yes, if requirements are separated into fixed, target and open items and suppliers are asked to state assumptions.How many models should be shortlisted?
Usually enough to preserve one technically credible alternative without diluting the validation effort.BUYING COMMITTEE ANSWERS
