Why Cevelar

Cevelar: Coverage is not a feeling.

Under time pressure, links between requirement, test, and norm break. Cevelar holds the chain so you run it once, not three times. Specs to defensible test plans for battery, EV, and energy-storage teams.

Why

You are not slow.
You are going in circles.

Every broken link sends the work back. Everything behind it gets done again. That is why Cevelar closes the chain before the audit does.

REQUIREMENTS TEST PLAN VALIDATION TESTING AUDIT a duty nobody turned into a test a test nobody tied to a clause a result nobody can trace to a page 3 PASSES 3 PASSES 2 PASSES

Once should be enough.

Cevelar closes every link before it can throw you back.

How it works

From a messy sentence to evidence.
Or to a visible gap.

This is how Cevelar holds the chain: one requirement from the document to linked evidence, or to a gap that is easy to miss by hand.

Requirements rarely arrive in one language. This one switches mid-sentence. Cevelar reads it as written, with no translation step in between.
Forward. Engineering builds the chain, duty by duty.
Backward. The audit starts at the evidence and walks it back to page 148.
If the chain only holds one way, it is not traceability.

The virtual engineers

You already know the shape.
Now it comes staffed.

Cevelar does not replace your V. It works inside it.

System spec Subsystem spec Component spec Component test Integration test System valid. NORM ENGINEER GAP BUILD ENGINEER coming soon
Reads the customer document and breaks it down into specifications that can actually be built against. Works its way down.

None of them chat. Each is a fixed, versioned procedure with a defined input and a defined output.

A test plan that already sits in the quote.

Spec structured, test plan drafted, effort estimated. The work that used to block a bid for weeks now lives inside the offer itself.

Quotes go out while the enquiry is still warm.

Demos

Same OS logic. Three domains.

Cevelar finds gaps in specs and standards and closes them with a defensible test plan.

Automotive SPICE requires end-to-end traceability: every requirement to its test and back. Cevelar shows where the chain holds and where it breaks.

9 gaps across 186 requirements. Cevelar closes them with linked test cases.

Traceability chain SWE.1 → SWE.6
  • SWE.1Software requirement SWE.4Unit test present linked
  • SWE.2Architecture element SWE.5Integration test linked
  • SWE.3Design element SWE.6no test case chain broken

UN 38.3 mandates eight transport tests. No cell ships without this evidence. Cevelar checks each test against the plan.

2 of 8 mandatory tests without evidence. Cevelar completes the plan before shipment.

  • T.5External short circuitevidence
  • T.6Impact / Crushno test case
  • T.7Overchargeno test case
  • T.8Forced dischargeevidence

The EU Battery Regulation makes the battery passport mandatory. Cevelar turns every required field into a testable requirement and shows what is still open.

11 of 112 required fields without a testable requirement. Cevelar turns them into concrete checks.

Cevelar closes every one of these gaps.
Any standard, any spec sheet.

Where is it hosted and is it GDPR compliant?

EU-hosted in Frankfurt. Sensitive engineering and spec data stay in Europe (GDPR / EU-only). No US-cloud default for production data.

How long does onboarding take?

Design partners typically start in days, not months: access, first OEM spec, first test plan. Founders onboard personally, no enterprise sales loop.

Do specs and IP stay with the customer?

Yes. Specs and derived artifacts stay under your control; processing is EU-hosted. Cevelar does not train public models on your specs.

What does Cevelar cost and how do I join the waitlist?

Design-partner access is via waitlist or founder demo. Pricing for production rollout is discussed personally, no self-serve checkout. Demo at cevelar.com/demo.

Why not Excel or an ALM like Polarion/Jira?

Excel breaks on traceability and standards mapping. ALMs store tests, they do not extract and map specs. Cevelar closes the gap from spec to structured test plan and exports into existing tools.

Cevelar is a solid partner for battery validation and test planning. Clear approach from requirements to structured test evidence, exactly what you need when certification and lab work have to stay aligned. Happy to recommend.
