Test a real charging station with a simulated vehicle. Reproduce charging behaviour and investigate unexpected responses.
For charging-station developers and manufacturers
Combine automated analysis, targeted simulation and electrical fault tests. Evaluate the software, test depth and engineering support with your own charging station.
Investigate how your charging station reacts to deliberately introduced communication and electrical faults. Match the fault cases and operating range to your test setup.
Full test scope for IEC 61851-23 Annex CC.7.5 test cases in the matching system configuration.
Share workspaces with colleagues. Keep live and logging controls within reach.

Discuss requirements and feedback directly with the team at the system.
From a customer decision: EVCA Multi Mobile, EVCA Flex with IEC 61851-23 and EVCA MCS. Usability, demonstrated test depth and confidence in the partner were decisive.
Available functions and test scope depend on the hardware, software release and agreed configuration. Together, we define a demonstration for your test task.
For commissioning, maintenance and service
Standards and practical test methods for charging station commissioning, inspection and service.
Micro: AC. Ultimate: AC/DC, depending on configuration.
For BMS developers
Set cell voltages and sensor signals. Investigate normal operation, boundary conditions and fault responses of your BMS.
Compare the energy measurement of AC and DC charging stations with a traceable reference, directly on site. Easy Chester Calimera documents the results.

Frequently asked questions
Start with an application when you need to define the test scope. Compare products when the DUT, charging role and required interfaces are already clear.
EVCA ComOnly tests EVCC or SECC controllers against a simulated communication partner. Other EVCA configurations add real-pair analysis, mobile testing or the electrical scope needed for a complete system test.
It supplies controlled cell voltages and sensor signals to a real BMS. Engineers can repeat nominal, boundary and configured fault conditions and check the controller response.
Supported interfaces depend on the product, software release and configuration. Define the required commands, measurements, test results and equipment ownership before selecting the integration scope.
Start with MCS testing for megawatt charging or EVCA ComOnly for controller communication. The required interfaces, protocol editions and electrical scope determine the system configuration.
