System of the Month April 2025: EVCA Multi Mobile for mobile EVSE testing
A mobile EVCA configuration combines AC and DC CCS charging tests with the customer’s resistive-load setup.

The configuration
- EVCA Multi Mobile
- AC and DC CCS testing
- Customer resistive-load integration
The engineering task
The customer wanted charging analysis and controlled tests in a setup that could move between test locations. Existing power equipment also needed to fit into the workflow.
The configuration
EVCA Multi Mobile provides the charging communication and measurement functions, with integration of the customer’s resistive load. The selected interfaces cover AC and DC CCS testing.
The practical benefit
Engineers can combine a portable charging-interface test system with the power equipment required for the task. The load and the configured electrical interfaces determine the applicable operating range.
