Independent,
in‑depth battery diagnostics.

On-site EIS testing for used EV and industrial batteries — analysed with AI, and documented so what a battery is actually worth stops being a guess.

What we do

An in-depth, independent read on any used battery's real condition.

We come to the battery, run a multi-frequency EIS scan on-site, and hand back a documented health profile — degradation patterns, safety flags, and a State of Health you can act on. Independent of the seller, the BMS, or a prior verdict from somewhere else.

01

On-site, non-destructive

A portable rig connects directly to the pack or module — no disassembly, no shipping, no lab queue.

02

Depth beyond a single number

DRT and AI-driven analysis surface specific degradation and safety signals, not just one SoH figure.

03

Independent of the BMS

EIS reads the cell's own electrochemistry directly, so the result holds up even when BMS history is thin or missing.

Fleet operators & battery holders

An answer, wherever the battery already is

On-site testing, no removal or shipping required, so the answer comes to the battery instead of the other way around.

How it works

Four steps, one visit

01

Connect

An on-site diagnostic rig connects to the pack or module where it already is — no disassembly, no lab transfer.

02

Scan

A multi-frequency EIS sweep runs in under a second per module, across chemistries.

03

Analyze

DRT deconvolution and AI pattern recognition flag specific degradation and safety risks — including early signs like lithium plating.

04

Document

A structured report is issued, built toward EN 18061 alignment and the EU Digital Battery Passport data format.
