System of the Month April 2026: EVCA Flex for EV Testing in the USA
How does a vehicle react when a charging station sends unexpected messages or delays a response? This EVCA Flex lets a customer in the USA investigate these behaviours under controlled conditions.
The configuration
- Integrated bidirectional DC CCS power circuit: 30 kW
- Up to 1000 V and up to 80 A, within the 30 kW operating envelope
- EV and EVSE simulation; Man-in-the-Middle with Sniffer
- Higher power and Manipulating Gateway as future extensions
Integrated power with room to grow
The 30 kW, 1000 V and 80 A limits describe an operating envelope, not a simultaneous maximum-power point. An upgrade to higher power classes is planned.
Control the simulated charging station’s behaviour
With comframe and Professional EVSE Simulation, the system acts as the charging station. The customer can vary communication parameters, message contents and timing to investigate the vehicle’s response to unexpected messages or delayed answers and assess charging robustness beyond the normal sequence.
Investigate simulations and real charging sessions
Man-in-the-Middle with Sniffer lets the customer analyse real charging sessions alongside tests with a simulated counterpart.
Add Manipulating Gateway in the future
A future Manipulating Gateway extension will let the customer intervene in the communication between a real vehicle and a real charging station and change communication parameters during charging. This provides a way to investigate suspected causes of interoperability issues and observe their effects directly. The extension is not part of the current delivered scope.
