System of the Month June 2025: high-power charging with deep protocol testing
A 350 kW-class EVCA Flex installation connects high-power charging tests with detailed protocol testing and reproduction of field recordings.

The configuration
- 350 kW-class test system
- Liquid-cooled CCS1, CCS2 and NACS connections
- 400 kW bidirectional source
- Charge Playback from field recordings
The engineering task
The customer needed to investigate charging behaviour at high power and reproduce communication sequences already observed in the field.
The installed configuration
The 38 HU EVCA Flex rack combines the configured charging interfaces with a 400 kW bidirectional source. Liquid-cooled CCS1, CCS2 and NACS connections support the selected test configurations.
From field trace to laboratory test
Charge Playback allows the customer to use charging recordings from its field measurement system as a basis for laboratory reproduction. The reported 350 kW test-system class and 400 kW source rating describe different parts of this installation.
