Oxaide BESS Forensic Audit Sample

Sample Technical Review // VERIFIED

Auditor: Oxaide Technical Review Team

Executive Summary // Example critical fault

Sample forensic review of BESS Asset #07 telemetry indicates an abnormal pattern in Cell Cluster 4B. Voltage sag and localized heating move together in a way that is consistent with rising internal resistance. In a live engagement, this would trigger immediate site review, operating restrictions, and follow-up evidence collection.

STATUS: CRITICALIMPACT: FIRE RISK (T-48h)ACTION: ISOLATE IMMEDIATELY

2. Analytical Notes

> REVIEW CONTEXT - Voltage dropped 0.19V in a 30ms window. - No matching load spike was visible on the DC bus. - Temperature rose +16.1C against the local cooling trend. > WORKING INTERPRETATION - Energy is likely being dissipated inside the cell rather than through expected load. - Internal resistance appears to be rising rapidly. > REVIEW POSITION - Separator damage or a related internal failure should be treated as a live possibility. - Site isolation and immediate follow-up inspection would be recommended.

Controlled Data Handling

Analysis can be run inside customer-controlled environments.
External data transfer is avoided unless the engagement explicitly requires it.
Retention and deletion follow the agreed review scope.
