System of the Month October 2025: EVCA testing according to IEC 61851-23 Annex CC

Project configuration

  • Returning DC charger manufacturer
  • High-power EVCA test upgrade
  • IEC 61851-23 fault-test functions
  • Separate 5 kW source for the existing bench

Extending established validation

As charging systems and validation tasks evolved, the manufacturer needed to expand the test capabilities of its existing infrastructure.

High-power testing and protocol work

The upgrade adds high-power EVCA testing and electrical fault-test functions according to IEC 61851-23 Annex CC. A separate 5 kW source supplies the existing protocol bench.

Two setups for distinct test tasks

High-power validation uses the upgraded EVCA installation. The separate source supplies the existing protocol bench with 5 kW.
