EVCA Platform
EVCA: EV Charging Testers for EV and EVSE
comemso EVCA is a configurable EV charging analyzer and simulator. Depending on the selected system, it supports EV testing with a simulated charging station, EVSE testing with a simulated vehicle, or analysis of a real EV–EVSE charging session. Interfaces, power equipment and software scope follow the test task.
Commissioning or servicing installed charging stations?
For guided installation and field checks, the Easy Chester workflow connects configured tests with a documented result. Micro supports AC-only 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 depth without treating every new task as a new test world.
Why it is a platform
The hardware boundary changes. The engineering logic stays connected.
EVCA systems share charging-specific software, reusable workflows and measurements linked to their test conditions.
Exact modules, licences, Test Libraries and interfaces depend on the selected EVCA system and release.
Charging-specific intelligence
Connect protocol states, timing, low-level signals and measured values with normative expectations.
Configurable physical boundary
Control the participant, interface, power level, fault condition, chamber boundary or real charging pair relevant to your test.
Reusable engineering work
Reuse approved configurations, test logic, captured charging behaviour and evidence where the released system supports it.
Six system paths
Choose the EVCA by the boundary you need to control.
Choose by the DUT (device under test) and test boundary. The six paths below cover controller communication, real-pair analysis, portable testing, laboratory power, MCS and EMC.
EVCA ComOnly
Start with EVCC or SECC communication development, protocol analysis, nominal and advanced simulation and applicable Conformance Test Libraries without building the complete power environment.
- Primary DUT
- EVCC or SECC
- Environment
- Bench and laboratory
- Use when
- Protocol behaviour is the test boundary
EVCA Interop
Capture the real charging pair on one timeline, isolate the cause and validate a correction hypothesis.
- Primary DUT
- The real charging pair
- Environment
- Field and laboratory
- Use when
- A real interaction failed or behaves inconsistently
EVCA Multi Mobile
Move between EV simulation, EVSE simulation and real-pair analysis with portable multi-standard hardware for vehicle, laboratory and field work.
- 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

| System path | Primary test boundary | Typical environment | What this path adds |
|---|---|---|---|
| EVCA ComOnly | EVCC or SECC communication | Bench and laboratory | Charging-protocol development, simulation, analysis and applicable conformance logic without the complete power stage. |
| EVCA Interop | Real EV-to-EVSE interaction | Field and laboratory | Synchronised real-pair evidence, root-cause isolation and validation of a correction hypothesis. |
| EVCA Multi Mobile | Portable EV, EVSE and real-pair interface | Vehicle, mobile laboratory and field | Multi-role, multi-standard access where the test system must move with the engineering team. |
| EVCA Flex | Controlled EV or EVSE laboratory counterpart | Laboratory and validation centre | External power integration, synchronised electrical depth, controlled faults, high-power and standards-specific hardware. |
| EVCA MCS | MCS communication, low-level signals, cooling and power | MCS system laboratory | Dedicated EV, EVSE and controller paths for the megawatt charging stack. |
| EMC Link | Optical charging communication across the chamber wall | EMC chamber | A transparent chamber boundary for charging communication. Stimulus, measurement and verdict remain with the configured laboratory systems. |
Growth architecture
Keep the core. Expand your test system.
The EVCA core is the brain of the system. In a compatible expansion, your existing core moves into a larger EVCA body, while comframe keeps the workflow and test logic connected.

Platform FAQ
Clarify the selection logic before configuring the system.
Is EVCA one physical device?
No. EVCA is a platform family with several physical system paths. Each path controls a different charging boundary while applicable systems share charging-focused software, capabilities and engineering logic.
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.
