About the Tuas, Singapore facility
Tuas is Singapore's main industrial area and the site of its next-generation port. The diagnostics hub opened on Tuas South Avenue 6 in 2021 to grade packs from Singapore and South-East Asia, where electrification of taxis, buses and delivery fleets is gathering pace. Its catchment covers Singapore and nearby markets, including Malaysia and Indonesia, where consolidated loads are received under the required import permits.
At 18,000 TPA, the hub tests fleet and passenger packs and supports regional trading of graded modules. Singapore's role as a trading and logistics centre makes it a practical base for supplying reusable modules to buyers across the region. Packs that do not qualify for reuse are consolidated and sent for processing, and every tested pack receives a serial-level grade report.

What happens to material here
- 1
Intake & safety triage
Packs are logged, thermally imaged and screened for swelling, coolant ingress or venting before entering the bench area.
- 2
Controlled de-energising
Residual energy is discharged to a safe state of charge with regenerative load banks and recorded per serial number.
- 3
Module-level capacity test
Full charge-discharge cycling at C/3 establishes usable capacity, internal resistance and cell-to-cell balance.
- 4
EIS fingerprinting
1 mHz–10 kHz impedance sweeps separate SEI growth, lithium plating and contact resistance degradation modes.
- 5
AI optical inspection
Machine-vision inspection of busbars, welds and cell cans flags mechanical defects that block second-life reuse.
- 6
Grade assignment
Grade A (≥85% SOH), B (75–85%), C (65–75%) and D routes are assigned, with D-grade material released to refining.
