System of the Month June 2025: high-power charging with deep protocol testing

The customer uses a 350 kW-class EVCA Flex system to test high-power charging and charging protocols, then reproduce field recordings in the laboratory.

System of the Month June 2025: high-power charging with deep protocol testing

The installed test system

  • 350 kW-class test system
  • Liquid-cooled CCS1, CCS2 and NACS connections
  • 400 kW bidirectional source
  • Charge Playback from field recordings

Investigate high-power charging

The customer needed to examine charging behaviour at high power and investigate the communication in detail. The laboratory tests also had to reproduce communication sequences captured in the field.

Charging interfaces and power source

The installation brings the configured charging interfaces and a 400 kW bidirectional source together in a 38 HU EVCA Flex rack.

Use field recordings in the laboratory

Charge Playback allows the customer to use charging recordings from its field measurement system as the basis for reproduction in the laboratory. The 350 kW test-system class and the 400 kW source rating refer to different parts of this installation.
