Q&A
A device can indeed be more precise locally — on a single vehicle, at a specific point in time. But the real question is not:
“What is the maximum precision on one vehicle?”
The real question is:
“How do you build a trusted infrastructure across 100,000 vehicles, integrated into digital workflows, without heavy logistics?”
Structural limitations of physical devices:
- Cost: ~€35 per diagnostic vs ~€10 for Bib. On a fleet of 10,000 vehicles, that’s a €250,000 difference.
- Logistics & Scalability: Each diagnostic requires an appointment, a technician, and vehicle immobilization. Across a multi-site fleet, this becomes a logistical project.
- Integration: A device produces a one-off report, not a signal consumable in real time by a pricing or underwriting engine.
- Monitoring: A device provides a snapshot at time T. Bib provides longitudinal tracking (degradation trajectory).
In summary:
A device is a unit-level diagnostic tool. Bib is signal infrastructure at scale. They solve different problems. And in cases where an additional physical measurement is required (premium certification, audit), Bib can integrate with field measurements.
Bib produces three types of battery reports: Flash, Standard, and Premium.
- The Flash Report is available for 100% of EVs, regardless of brand or model.
- For Standard and Premium reports, eligibility varies by vehicle, as not all manufacturers share their data. Check our eligibility documentation for more details.
Bib does not rely exclusively on OEM data.
The architecture is designed in three layers:
- OEM cloud data (when available): the richest source, feeding Standard and Premium Reports.
- Driving and charging data (collected via telematics partners): enabling independent SoH calculation.
- Flash Report (always available): based on statistical data from the Bib fleet (age, mileage, model, degradation patterns observed on comparable vehicles). Flash SoH guarantees a response for 100% of requests, with an explicit confidence level (~±5%). This fallback is a contractual promise: no request remains unanswered. No workflow is blocked.
The two figures do not measure the same thing.
OEM SoH is calculated by the manufacturer using its proprietary method, often based on gross capacity (including a protective buffer).
Bib SoH is calculated independently, based on net capacity (energy actually usable by the driver), and standardized across OEMs.
Why this matters:
An OEM SoH can remain high while available energy declines — the buffer absorbs degradation.
Thus, a 90% OEM SoH at Kia does not mean the same thing as a 90% OEM SoH at Renault. Methods differ, buffers differ, reference baselines differ.
Bib SoH is designed to be comparable across brands. That is its core purpose.
The observed gap (typically 5 to 15 points) is not an error. It is the result of rigorous standardization. And that gap is precisely where the value lies: without it, comparing two vehicles from different brands on battery health would be impossible.
No — and that is a deliberate choice.
Bib produces certifiable data: standardized, timestamped, traceable, documented, and robust enough to withstand audit. It is the material of certification.
The certification itself — meaning the formal validation that a process complies with a recognized standard — is delivered by accredited third parties.
This separation is strategic: It guarantees Bib’s neutrality: we are not judge and party.
- It strengthens the credibility of the signal: an SoH certified by a third party carries more weight than a self-certified SoH.
- It enables flexibility: different markets or regulators may recognize different certifiers, without requiring Bib to modify its infrastructure.
Bib is an information infrastructure, not an investment advisor.
SoH is a standardized signal, delivered with an explicit confidence interval and full traceability. The governance framework is designed so that clients can integrate the signal into their internal policies in an audit-ready manner:
- Traceability: Every result is timestamped; sources are documented; methodology is auditable.
- Explicit uncertainty: Clients know exactly the confidence level of each result. A decision based on Flash Report (±5%) does not carry the same weight as one based on Premium Report (maximum precision).
- Contractual documentation: Terms of use clearly define what Bib provides (a signal) and what the client does with it (a decision).
- No performance guarantee: Bib does not promise that the residual value will be correct. Bib promises that the measurement is the best available, standardized, and auditable.
In practice, responsibility works the same way as with credit rating agencies or market data providers: They provide information. The decision-maker bears the decision.
