Arctura’s proprietary Rating Standard · ARS

Every physical asset
gets an A–F rating.

Know the risk. Reconstruct the cause. Defend the decision.

One scoring engine reads battery health, usage behaviour, market risk and compliance — and returns a single, defensible A–F grade for any asset class. Moody’s-tier discipline, for the physical world.

The category

A standard,
not just a score.

Others issue the certificates and passports — the OEM, the owner, the building surveyor. Arctura is the rating overlay on top: we read what they issue and grade it A–F against one institutional standard.

Moody’s rates the bond; it doesn’t issue it. Arctura rates the physical asset — across 14 asset classes and a matrix of certificate types — so lessors, insurers and lenders can price what they hold as precisely as a financial instrument.

The engine

Four signals, one score.

The Total Asset Score composes four independent risk pillars into a single grade — a pure function of configuration and telemetry, portable across every asset class.

01
Battery health

SoH trajectory, degradation slope, charging patterns. LFP degradation validated in shape — sub-5% trajectory error, LFP/MATR reference.

02
Usage & behaviour

Duty cycle, overrun, DC fast-charge frequency — how the asset is actually driven or cycled, not just its age.

03
Contractual & market

Residual-value gap, term, brand and model factor. The exposure the paper carries.

04
Environment & compliance

CSRD, ESG, passport-readiness — whether the asset can stand up to the regulation coming for it.

Point solutions cover one or two of these pillars — combining all four into a single A–F grade is Arctura’s approach. How the pillars are weighted is proprietary.

The attestation

A rating you can hand to a counterparty.

Every grade can be issued as a hash-verifiable attestation — a did:web credential written to an append-only SHA-256 hash chain. Arctura issues its own rating attestation; the OEM or owner issues the regulatory Battery Passport. We read and rate theirs — we never issue it.

  • Rating attestation (DHC / BEHC), portable across parties
  • did:web identity + W3C Verifiable Credential 2.0
  • Append-only SHA-256 hash chain — verify the record hasn't drifted

Two ways in

One engine. Two ways to use it.

ENTERPRISE
Asset rating

The A–F rating standard, delivered by API to funds, operators, lessors and lenders. Priced per asset, per class, billed to the party that carries the risk — insurers recognise the rating, they don't buy it.

Fleet Ops

Where this all started. A self-serve operations product for smaller fleets — sign up, connect, run. A different motion for a different buyer; never the same customer as the enterprise rating.

How we validate

We pressure-test the models before they rate anything.

Every model is stress-tested against a synthetic falsifiability substrate — synthetic, not a customer, not a live deployment — before it goes near a production grade. Duty-robustness is proven (heavy-transport ↔ grid-storage zero-shot under 3%); data synergy is not claimed.
