Test both sides of the MCS interface
System configurations for vehicles, charging stations and controllers.
MCS EV testing
Simulate the MCS charging station for EVCC (vehicle-side charging communication controller), charging subsystem and complete-vehicle tests. Configure the MCS EVSE (electric vehicle supply equipment, or charging station) simulator with the cooled cable and external source required by the approved full-system test.
- Charging-station communication and low-level simulation
- Cooled cable and connector temperature monitoring
- External bidirectional source control
- Vehicle reaction correlated with power and timing
MCS EVSE testing
Simulate the heavy-duty vehicle and its battery requests for SECC (station-side charging communication controller), dispenser and full-charger development. The MCS EV simulator coordinates separately configured external DC source/load equipment for battery emulation.
- Vehicle communication and charging requests
- MCS inlet and low-level vehicle signals
- Battery-emulation and load integration
- SECC and power-stage behaviour on one timeline
MCS ComOnly
Develop and test EVCC or SECC communication, certificates, 10BASE-T1S and low-level signals on the MCS controller bench.
- Communication-focused bench testing
- Individual low-level signal access
- Extend the same test workflow with full-power hardware
Communication and low-level MCS
Analyse communication, signals and power in the MCS test setup.
Correlate the following layers in the released MCS configuration.
Simulate and monitor Charge Enable and Insertion Detection according to the released system scope.
Observe the temperature channels that protect the high-current connection and cooling architecture.
Include the auxiliary voltage environment required by the selected MCS direction.
Measure and analyse the single-pair Ethernet environment below the application protocol.
Analyse secure communication and protocol-level BPT services within the released scope. Physical reverse energy flow is a separate hardware configuration using suitable external source/load equipment; neither scope alone demonstrates complete bidirectional MCS system conformity.
High-power testing with detailed protocol analysis
Plan the power stage for maximum and continuous operation.
Define voltage, current, maximum power and continuous operating points separately for the selected configuration. Continuous performance depends on the source or load, mains connection, cable, coupler, cooling, ambient conditions, temperature channels and duty cycle.
Published system limits
- Maximum voltage
- Up to 1,500 VPublished hardware system limit
- Maximum current
- Up to 1,500 AHigher current on request
- Maximum power
- Up to 2.25 MWPublished power class
- Continuous duty
- Project-specificPower, cable, cooling and ambient conditions
The standards-based MCS EV-side voltage range is limited to 1,250 V in the applicable scope. DUT ratings, released test-library configuration and continuous-duty requirements remain project-specific.
Integrated liquid cooling
EV testing and applicable Man-in-the-Middle setups. A liquid-cooled MCS cable and rack cooling support demanding vehicle tests and applicable real-pair setups that carry high current for extended durations.
MCS inlet for charger and reduced-power tests
EVSE testing and reduced-power applications. Match the MCS inlet and project-specific thermal architecture to your charger test or reduced-power application.

Frequently asked questions
EVCA MCS product FAQ
What is EVCA MCS?
EVCA MCS is the dedicated Megawatt Charging System test path within the EVCA platform. It combines MCS communication, low-level signals, coupler or inlet, temperatures, control of separately configured external DC source/load equipment, cooling options and comframe analysis for vehicle, charging-station and controller development.
Can the platform test both MCS vehicles and charging stations?
Yes. Simulate the charging station to test the vehicle, or simulate the heavy-duty vehicle and battery to test the charger. The selected configuration defines interface hardware, cooling, power equipment, signals, communication and safety.
What are the published maximum system classes?
The hardware platform can be configured up to 1,500 V, up to 1,500 A and up to 2.25 MW, with higher current available on request. The standards-based MCS EV-side voltage range is limited to 1,250 V in the applicable scope. These maxima are independent configuration limits and must not be assumed to be simultaneously available; DUT rating, released test-library configuration and continuous-duty requirements remain project-specific.
Does the system include liquid cooling?
The dedicated rack can be configured with integrated liquid cooling for vehicle testing and applicable high-current setups. Charger and reduced-power configurations can use the inlet and a project-specific thermal architecture without the integrated rack cooling unit.
Which low-level MCS signals are supported?
The current product scope describes simulation and monitoring of Charge Enable and Insertion Detection, plug and inlet temperatures and auxiliary voltage for EV and EVSE. Exact signal access and automation depend on the released configuration.
What is MCS ComOnly?
MCS ComOnly is the communication-focused configuration for EVCC and SECC development without voltage and current. It provides the MCS communication and low-level environment before a full-power laboratory is required.
