How eBatt Atlas Works
eBatt Atlas assesses battery manufacturers on evidence, not relationships. This page publishes the full model: how a manufacturer enters Atlas, how its confidence score is computed, how that score decays and re-verifies, the hard floors that bound it, the criteria for the Verified Vendor badge, and the gates that govern user-submitted evidence. The scoring is auditable and evidence-based — not pay-to-play.
How a manufacturer enters Atlas
Manufacturers are admitted through a reviewed sequence, not an open submission form:
- Discovery — a candidate manufacturer is identified from market research, references, or direct outreach.
- CRM intake — the candidate and its initial evidence are recorded for tracking.
- Human-in-the-loop review — a reviewer validates the manufacturer's evidence pack against the confidence model before anything is published.
- Approval — only after review does the manufacturer appear in Atlas with a computed confidence score.
The confidence model
A manufacturer's confidence score is a weighted combination of six components. The weights below are the exact weights the scoring engine uses; they sum to 100%.
| Component | Weight | Inputs |
|---|---|---|
| Reference projects | 30% | count, age, scale, geographic diversity, verifiability |
| Compliance certificates | 20% | standards held, currency (expired = 0), cert verifiability |
| Manufacturer tier | 15% | allowlist tier, years operating, ownership stability |
| Field-failure record | 15% | public incidents, recalls, advisories (penalty) |
| Data freshness | 10% | days since last verification |
| Verified user evidence | 10% | gated user-submitted reference projects + ratings (§6.3.6) — rolling out, not yet enforced |
| Total | 100% |
Decay and re-verification
Evidence ages. A confidence score is not a one-time stamp — it decays over time so that stale evidence carries less weight, and it recovers when a manufacturer is re-verified. Decay is chemistry-aware: the faster a chemistry's field behaviour and standards landscape move, the faster its evidence decays.
| Chemistry | Decay speed | Approximate half-life |
|---|---|---|
| Mature lead-acid | Slow | ~730-day half-life |
| Mainstream lithium | Medium | ~365-day half-life |
| Emerging chemistries | Fast | ~120-day half-life |
Re-verification resets the data-freshness component and refreshes the underlying evidence, restoring a score that decay has eroded. The cadence tracks the chemistry: fast-moving chemistries are re-verified more often than mature ones.
Hard floors
Two rules bound the score regardless of how strong the other evidence is:
- Expired certificate → confidence 0. A lapsed compliance certificate is treated as no certificate. The manufacturer cannot carry a confidence score on the strength of credentials it no longer holds.
- Cap of 60 without a qualifying reference project. Confidence cannot exceed 60 unless the manufacturer has at least one verified reference project meeting a chemistry-aware age floor — at least 3 years in service for mature chemistries, at least 1 year for emerging ones. Paperwork alone cannot buy a high score; the product must have a verifiable track record in the field.
Verified Vendor badge criteria
The Verified Vendor badge is the only vendor badge in Atlas. It is binary and earnable: a manufacturer either meets the published criteria or it does not. The badge is awarded on evidence, not on any relationship with eBatt, and there is no paid or invited tier above it.
A manufacturer earns the badge by completing a full self-registration evidence pack:
- Verified company identity and ownership.
- Current, independently checkable compliance certificates (no expired credentials).
- At least one verified reference project meeting the chemistry-aware age floor.
- A clean or fully disclosed field-failure record.
The badge is criteria-only here — this page publishes what it takes to earn it; it does not award it.
User-evidence anti-gaming gates
Status: rolling out — not yet enforced. The gates below are the published design for user-submitted evidence. Until this program ships, the verified-user-evidence component contributes 0 to every score — no user submission currently moves a manufacturer's confidence.
Users can contribute evidence — reference projects and ratings — but only through gates designed to keep the score honest. User evidence contributes at most its 10% weight and can never override hard evidence.
| Gate | Rule |
|---|---|
| Identity verification | Submitter is a verified account; anonymous submissions are not scored. |
| Project verifiability | A submitted reference project must be independently checkable (named site, scale, commissioning date) before it can count. |
| Conflict-of-interest screen | Submissions from accounts affiliated with the manufacturer are excluded from that manufacturer's score. |
| Rate + duplicate limiting | Repeated or duplicated submissions are collapsed; volume alone cannot move a score. |
| Capped contribution | Verified user evidence contributes at most its 10% weight — it can never override hard evidence. |
Onboarding disclosure
EverExceed was onboarded as the first manufacturer in eBatt Atlas due to a longstanding pre-launch relationship with the founder. They were assessed on the same evidence basis as every subsequent manufacturer and earned their confidence score on that basis alone.
