The specific case.
Cell, temperature, operating profile and warranty conditions. We identify the information available and the assumptions the study needs.
The Kyklios degradation model
Your project's
curve.
The manufacturer's curve is a reasonable reference for a generic use. Our study relates the battery to your operation, your site and the conditions of your contract.

From conditions to decision
A model of our own.
Assumptions that can be reviewed.
We use the degradation model in our engineering studies. The question is not only how much capacity the battery loses, but what that trajectory means for the size of the system, its warranty and the capacity additions.
Time and use.
We relate calendar ageing to the ageing associated with cycling. The uncertainty is explained alongside the results.
A basis for deciding.
A technical reading of the result, its assumptions and its limits, to be checked against the needs of the project.
The model, in motion
Change the use.
The curve changes.
A synthetic example to see the mechanism. Move the cycles, the depth of discharge and the temperature: the trajectory moves and the guaranteed schedule stays where it is.
Drag the dispatch. The guaranteed curve does not move.

This is the outcome that matters and the one nobody prices in: the same battery, under the same guaranteed schedule, clears it or breaches it depending on how you dispatch it. The curve the manufacturer gave you assumed a profile. Yours is in your revenue model, and the two were never compared. That is why a verdict without a scenario is worth nothing, and why we will not hand you one.
Synthetic example, illustrative shapes only, not the calibrated model. A 10 MW / 40 MWh system, LFP 314 Ah cell, annual schedule to year 20. A real study models your cell, your site and your contract.
A report that can be checked
What a reviewer can
verify without us.
The model is calibrated on public laboratory data. When the manufacturer or the client provides their own data, the study uses it as an anchor and says so.
Deterministic
The same inputs give the same result. No black box and no model that quietly changes.
Provenance
Every coefficient carries a citation. A parameter with no traceable source does not enter the calculation.
A range, not a line
Results are delivered as P50 and P90 trajectories. Where the margin is narrower than the band, we say so.
Audit manifest
Model version, a hash of every input and output, and the origin of every figure. A reviewer verifies it with sha256 and the manifest, with no access to us.
Specific assignments
What do you need
to put to the test?
These assignments can be contracted separately. The scope is agreed according to the information available and the decision ahead of you.
Sizing and useful life.
We study the capacity the project needs, how it evolves under the planned use and when it may require an addition. The result provides a technical basis for comparing configurations.
Propose a studyWarranties and contracts.
We review what is guaranteed, how it is measured and which conditions can void coverage. We check the planned operation against the technical schedules and the responsibilities.
Review a warrantyBefore buying an asset.
We review the condition of the battery, the warranty that remains and the pending capacity additions. The information available determines what we can conclude and what needs verifying.

The battery within
your work.
Manufacturers and suppliers
An independent reading of the product and its datasheet, oriented to the project's questions.
EMS and sizing partners
We study the degradation curve of a specific case against a flat rate. Its integration into other tools is assessed case by case.
Engineering firms
We can provide the battery study within your report. Scope, responsibility and deliverable are agreed before we start.
Scope of the model
The result needs
its context.
A curve tied to its assumptions
The result corresponds to the cell, the operation and the conditions declared. If they change, the study has to be reviewed. The limits of the information must accompany the conclusion.
Degradation and availability are different things
The model studies degradation. It does not produce a plant availability forecast. Contractual obligations require their own review.
An engineering capability
We do not sell a self-service application. We deliver engineering studies supported by the model. The report is not a certification and does not replace the independent engineer a bank appoints.
