What to bring to the review
- Exact battery, host and relevant charger revisions
- Confirmed requirements, proposed targets and unresolved questions kept separate
- A responsible owner and evidence location for each decision
9 fields for a BMS-to-host message dictionary
Use a row with field number, requirement, responsible party, revision, evidence link and decision. Keep the original measurements or documents available to the authorized project team. Mark missing evidence as open; do not replace it with an estimated pass.
- 1. Identifier: name the message and the interface-document revision.
- 2. Direction: identify the sender, receiver and request-response relationship.
- 3. Encoding: define field position, length, signedness and byte order.
- 4. Units: state scaling, offset and the physical meaning of each reported value.
- 5. Validity: distinguish available, unavailable, invalid and stale data.
- 6. Timing: agree update, timeout and recovery behavior for the actual application.
- 7. Fault meaning: separate warnings, protection events and communication failures.
- 8. Host action: define who limits, inhibits, stops or requests recovery.
- 9. Evidence: link representative exchanges to exact BMS and host firmware revisions.
Use the record to make a scoped decision
Use agreed example messages to check decoding at both ends, including boundary and unavailable-value cases. Test timeout handling separately from normal traffic. Keep a warning or stale value distinct from permission to operate; the host action must follow the agreed interface and system requirements.
Keep acceptance limits explicit
A protection board does not necessarily provide a digital communication interface. Confirm the actual hardware and agreed protocol before specifying messages.
Technical context and limits
This protector illustrates that protection functions, thresholds and delays are device-specific. Consult the documentation for the actual hardware. Citing this example does not identify a component used by Jinfan or establish system qualification.
