EVCA MCS: Megawatt Charging Test System
Test an MCS truck or charging station with a defined simulated partner. Combine the supported communication and signals with power and cooling equipment that can sustain the required operating points.

Dedicated MCS test equipment within the EVCA platform
A concrete system for MCS communication, low-level signals, thermal interfaces and scalable power.
EVCA MCS retains the charging-focused configuration, measurement and analysis principles of the EVCA platform while adding the dedicated MCS coupler or inlet, 10BASE-T1S, MCS-specific low-level states, connector temperature access and project-specific high-power and cooling integration.
The final system is selected from the device under test. The vehicle path represents the charging station. The charger path represents the heavy-duty vehicle and battery. A communication-first path starts controller development without voltage or current and preserves the route to a full-power laboratory.

Test both sides of the MCS interface
One platform family. Three concrete product paths.
Use the system as the controlled charging partner the real DUT needs.

MCS EV testing
Use the MCS EVSE (electric vehicle supply equipment, or charging station) simulator for EVCC (vehicle-side charging communication controller), charging subsystem and complete-vehicle tests. Add the cooled MCS cable and external source required for 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
Use the MCS EV simulator for SECC (station-side charging communication controller), dispenser and full-charger development. Represent heavy-duty vehicle and battery requests and coordinate separately configured external DC source/load equipment as 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
Start EVCC or SECC communication, certificates, 10BASE-T1S and low-level signal work before high voltage and current are required.
- Communication-focused bench testing
- Individual low-level signal access
- Path to full-power hardware without changing the workflow
Communication and low-level MCS
Test the complete MCS stack without turning the power stage into a black box.
The released implementation combines low-level signals and connector temperatures with single-pair Ethernet, ISO 15118 application behaviour and available electrical measurements.

Charge Enable and ID
Simulate and monitor Charge Enable and Insertion Detection according to the released system scope.
Plug and inlet temperature
Observe the temperature channels that protect the high-current connection and cooling architecture.
EV and EVSE supply
Include the auxiliary voltage environment required by the selected MCS direction.
10BASE-T1S
Measure and analyse the single-pair Ethernet environment below the application protocol.
TLS, charging and BPT
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.
Power without losing protocol depth
Separate voltage, current, maximum power and continuous duty before choosing the hardware.
The published system classes are not one guaranteed simultaneous operating point. Continuous performance depends on the selected source or load, mains connection, cable, coupler, cooling, ambient conditions, temperature channels and duty cycle.

Integrated liquid-cooling configuration
Use the cooled MCS cable and rack cooling for demanding vehicle tests and applicable setups that carry high current for extended durations.
Configuration without integrated rack cooling
Use the MCS inlet and project-specific thermal architecture for charger tests or applications that do not require the integrated cooling unit.

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. For vehicle testing it represents the charging-station side. For charger testing it represents the heavy-duty vehicle and battery side. 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 1.5 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.
MCS test planning
Define communication, interface and power scope separately.
Specify the DUT role, MCS interface, thermal context and separately configured source/load equipment.
Select the right EVCA path
Choose the dedicated MCS path only when the MCS architecture is part of the test object.
