Pre-Loading Yard — BMS Data Pull Integration Trial
In a terminal pre-loading yard with single-OEM cargo, we tested pulling per-vehicle BMS data and fusing it with the yard's thermal coverage. Stage-1 detection became feasible.
The closed-loop BMS handshake is the destination architecture. The first place to test it is where the cargo is still under terminal-operator control and a single OEM's BMS is reachable. We worked with an OEM and the terminal operator on a pre-loading yard pilot — pulling per-vehicle BMS state and fusing it with the yard's thermal coverage layer.
What the BMS pull added
- Per-vehicle SoC, cell voltage spread, and internal temperature available alongside external sensors.
- Detection of internal cell anomalies (Stage 1) that no external sensor can see.
- Cross-validation between BMS internal temperature and our external IR cells.
- Pre-shipment SoC verification automated, removing a manual handoff step.
Outcome
The Stage-1 detection from BMS alone is the first operational demonstration we have run. The fusion of internal and external signals dramatically tightened the false-positive rate compared to either alone — the two sensor classes corroborate or contradict each other within seconds.

The BMS Handshake — Pre-Fire Shutdown as a Detection-Layer Output
Off-gas detection vendors in ESS markets tie the sensor directly into the BMS to shut down the affected stack. The marine analogue is harder — but the principle still applies.
OEM Finished-Vehicle Yard — Pre-Export Coverage
An OEM finished-vehicle yard at a manufacturing plant — 14,000 EVs in rotation, no thermal coverage before this pilot. The threat model is closer to the bench than to the deck.
