What the site does
Poland has become one of Europe's major centres for battery cell and component manufacturing, and Warsaw is a hub for logistics and fleet operations in central Europe. The grading centre opened on ulica Poleczki in 2022 to serve Poland and neighbouring countries, giving central European customers a closer alternative to sending material to western Europe for testing. Cross-border loads are handled routinely.
At 17,000 TPA, it grades passenger and commercial packs, electric bus packs from city transport operators, and modules and production material from regional manufacturers. Reusable modules are passed on for second-life builds, while material below threshold is sent for black mass production. Grade reports are issued for every pack tested, and regional manufacturers use the centre to assess rejected and end-of-line material before deciding what to do with it.
What arrives at the gate
Feedstock at Warsaw, Mazovia reflects its catchment and plant type. Every consignment is weighed, photographed and logged against the originating manifest before it enters the process area.
- Fleet and dealer packs from Poland
- Production material from central European battery plants
- Electric bus packs from city transport operators
- Packs from neighbouring countries
The process, step by step
The 3 operating lines — module soh bench, eis diagnostics laboratory, ai optical cell grading — run the sequence below.
| Stage | What happens |
|---|---|
| Intake & safety triage | Packs are logged, thermally imaged and screened for swelling, coolant ingress or venting before entering the bench area. |
| Controlled de-energising | Residual energy is discharged to a safe state of charge with regenerative load banks and recorded per serial number. |
| Module-level capacity test | Full charge-discharge cycling at C/3 establishes usable capacity, internal resistance and cell-to-cell balance. |
| EIS fingerprinting | 1 mHz–10 kHz impedance sweeps separate SEI growth, lithium plating and contact resistance degradation modes. |
| AI optical inspection | Machine-vision inspection of busbars, welds and cell cans flags mechanical defects that block second-life reuse. |
| Grade assignment | Grade A (≥85% SOH), B (75–85%), C (65–75%) and D routes are assigned, with D-grade material released to refining. |
What sets the site apart
Central European base. Serves Poland and nearby markets without long hauls west.
Manufacturing support. Handles material from the region's battery production.
Bus pack grading. Tests packs from urban electric bus fleets.
Where material goes next
Material that Warsaw, Mazovia does not finish on site moves to the nearest specialist facility in the network, keeping transport distances and dwell times down.
| Facility | Role | Distance |
|---|---|---|
| Zwickau — Saxony Second-Life Works | Second-Life BESS Works | 613 km |
| Rotterdam — Maasvlakte Refining Works | Hydrometallurgical Refinery | 1,128 km |
