BESS forensic methods that support diligence, warranty, and post-COD decisions
This page shows how Oxaide evaluates battery risk when a decision needs more than dashboard summaries or vendor claims.
Why clients use this page
Use this method map first, then go deeper only if needed.
Most teams want to understand the review logic before they commission work. This page gives that logic in plain language.
It shows the method sequence, how each layer connects, and where to open validation or chart-level evidence when required.
What this page is
A decision-led method map
A clear view of how Oxaide reviews battery risk before a diligence, warranty, or post-COD scope is locked.
What supports it
Benchmark-backed, not benchmark-trapped
Oxford and NASA references support the logic. Full benchmark charts are available when your technical team wants depth.
What it is not
Not a substitute for live review
This map explains the approach. It does not replace site telemetry review, operating history analysis, or mandate-specific recommendations.
Method sequence
The review sequence used on real mandates.
Each step answers a practical question and reduces uncertainty before the next layer is applied.
Start with telemetry posture and operating regime
Before chemistry conclusions, confirm data quality, comparability, and operating context so the findings can be trusted.
Then read chemistry and slow-health signal
Use ICA, DVA corroboration, and knee-point framing to separate real degradation behavior from summary SoH noise.
Pressure-test resistance, heat, and precursor behavior
Assess resistance rise and plating risk early, because safety, warranty, and downside issues usually emerge before clean capacity narratives.
Keep the claim boundary explicit
Keep proof limits explicit so stakeholders can see where public benchmarks stop and live-asset review begins.

Start with the map, then drill into the specific diagnostic lens that matters for your case.
Incremental Capacity Analysis (dQ/dV)
The lead chemistry-fingerprint method for LFP-first BESS diligence, degradation diagnosis, and clear forensic review.
DCIR and Resistance Rise
The physical stress, heat-generation, and power-fade layer that matters in safety review, warranty evidence, and post-COD operating checks.
Lithium Plating Detection
Why plating risk matters long before an operator can defend the issue with dashboard-level summaries alone.
Knee-Point and RUL Framing
How slow-health estimation, acceleration risk, and intervention timing should be read before predictive-maintenance claims get loose.
Usable Capacity vs BMS SoH
The gap that matters in underwriting, SPA negotiations, warranty review, and investor-led battery diligence.
How Oxaide Reads BESS Telemetry
The practical sequence from telemetry triage through spread, resistance, ICA, DVA, and decision synthesis.
Commercial route
Start with the review path that matches your live decision.
For acquisition, refinancing, and investment decisions where asset condition must stand up under scrutiny.
For claims, disputes, renewals, and insurer conversations that require defensible technical evidence.
For operating sites where drift, thermal stress, or degradation must be addressed before costs escalate.
For teams that want a clear view of proof boundaries before commissioning a review.
A chart-by-chart appendix for reviewers who need full benchmark visual context.
Scope first
Defined review scope
Boundary, telemetry window, and mandate question are pinned down before conclusions move.
Encrypted handling
Protected review workflow
Review traffic and operating data are handled with encrypted transfer and controlled access.
Customer boundary
Customer-controlled deployment
Managed, private, and isolated deployment paths are available when the environment requires them.
Direct accountability
Principal sign-off
Technical accountability stays close to the method rather than disappearing into a generic workflow.
