EVCA: EV charging tester for EV and EVSE testing
Use the comemso EVCA platform as an EV charging tester or EVSE tester for charging development. Test a charging station with simulated vehicle behaviour, test an electric vehicle with a simulated station, or analyse a real charging pair. Choose interfaces, power equipment and software for the test task.
Commissioning or servicing installed charging stations?
For commissioning and service, Easy Chester guides you through the configured installation and field checks and documents the results. Micro covers AC tasks; Ultimate adds DC charging tests.
EV, EVSE (electric vehicle supply equipment, or charging station), EVCC (vehicle-side charging communication controller), SECC (station-side charging communication controller), real pair and MCS paths.
Communication, interface, power, faults, chamber and field.
Charging-focused configuration, analysis, automation and evidence.
Extend the test depth while reusing the platform’s test methods and workflows.
Shared software and test methods
Reuse your test methods across EVCA systems
An EV charging tester from the EVCA family uses charging-specific software and reusable workflows. Keep measurements together with the conditions under which they were recorded.
Charging-protocol analysis
Connect protocol states, timing, low-level signals and measured values with normative expectations.
Configure the physical test setup
Use the configured EV charging tester to simulate the counterpart required by your DUT, or measure a real charging pair. Select the interface, power level and supported faults. Define the chamber connection or real-pair setup where the task requires it.
Reuse configurations and test cases
Reuse approved configurations, test logic, captured charging behaviour and evidence where the released system supports it.
Six system paths
Choose your EV tester or EV charger tester configuration
In the January 2025 customer project, EVCA Multi Mobile connects on-site testing with a Gustav Klein power source in the laboratory.
Choose an electric vehicle tester or EV charger test equipment around your DUT (device under test) and test role. The six system paths cover controller communication, real-pair analysis, portable testing, laboratory power, MCS and EMC.

EVCA ComOnly
Develop EVCC or SECC communication with protocol analysis, nominal and advanced simulation and the applicable Conformance Test Libraries at the controller bench.
- Primary DUT
- EVCC or SECC
- Environment
- Bench and laboratory
- Use when
- Protocol behaviour is the test boundary

EVCA Interop
Record the real charging pair on one timeline, locate the deviation and test the proposed correction under defined conditions.
- Primary DUT
- The real charging pair
- Environment
- Field and laboratory
- Use when
- You need to investigate how a real vehicle and station interact

EVCA Multi Mobile
Use portable multi-standard hardware for EV simulation, EVSE simulation and real-pair analysis in the vehicle, laboratory or field.
- Primary DUT
- EV, EVSE or real pair
- Environment
- Mobile laboratory and field
- Use when
- One portable system must cover several roles

EVCA Flex
Build a modular EV or EVSE test environment around external source and load hardware, synchronised measurement, electrical faults, high-power operation and standards-specific test hardware.
- Primary DUT
- Complete EV or EVSE charging system
- Environment
- Laboratory and validation centre
- Use when
- Power, faults and deeper physical verification matter

EVCA MCS
Address MCS EV, EVSE and communication testing with charging-specific protocol, low-level signals, temperature and cooling interfaces and scalable power integration.
- Primary DUT
- MCS EV, EVSE or controller
- Environment
- MCS laboratory and system test
- Use when
- The complete megawatt charging stack must be controlled

EMC Link
Preserve charging communication through the EMC chamber with a transparent optical link while the approved measurement and test systems remain outside the chamber.
- Primary DUT
- EV, EVSE or charging interface under EMC stress
- Environment
- EMC chamber
- Use when
- The chamber boundary must not distort communication

Platform FAQ
EVCA selection and configuration FAQ
Is EVCA one physical device?
EVCA is a family of test systems for different charging tasks. Applicable systems share charging-specific software, capabilities and test methods; the hardware is selected for the charging interface and physical test scope.
Which EVCA system should be selected first?
Start with the DUT and physical boundary. Select ComOnly for controller communication, Interop for a real EV-to-EVSE pair, Multi Mobile for portable multi-role work, Flex for laboratory power and faults, MCS for megawatt charging or EMC Link for the chamber boundary.
Can an EVCA configuration grow later?
Yes, where the hardware generation, interfaces, licences, Test Libraries and project architecture allow it. The reviewed upgrade or migration path is authoritative for the concrete system.
Does every EVCA contain every capability?
No. Capability availability depends on the selected product, charging standard, role, software modules, licences, Test Libraries, interfaces and released configuration.
