Prepare for the EU Battery Regulation – Validate with Confidence

The EU Battery Regulation (EU 2023/1542) introduces stricter requirements for safety, performance, traceability, and conformity assessment across the battery lifecycle.

We provide accredited testing to verify durability, electrical safety, EMC performance, and environmental resilience — supporting compliance from development through market approval.

Reproducible results. Traceable data. Regulation-ready validation.

Your Testing Partner for Battery Systems

Battery qualification demands coordinated validation across electrical, mechanical, environmental, and EMC disciplines. We provide accredited, high-power testing infrastructure and structured project execution tailored to complex battery programs.

With expertise in high-voltage systems, thermal behaviour, and long-term durability, we deliver reproducible results, clear documentation, and certification-ready data — supporting efficient approvals and confident market release.
