MCS tester for trucks and megawatt chargers

Test megawatt charging before the first truck charges.

EVCA MCS simulates the charging station for MCS truck tests or the vehicle for MCS charger tests, with power and cooling for the operating points you need before the first truck charges – instead of a test setup built from scratch for each project.¹

Operating points up to 1,500 A and 2.25 MW.

In 30 seconds

What for: Truck makers and megawatt-charger developers, before the first depot goes live.
What it does: Simulates the charging station or the truck, with power and cooling for operating points up to 1,500 A and 2.25 MW.
Not for: Car charging with CCS – that is EVCA Flex.

An MCS session that fails in the depot stops a truck – and its delivery schedule.

Dedicated MCS test equipment within the EVCA platform

MCS communication, low-level signals, thermal interfaces and scalable power in one test system.

A dedicated MCS coupler or inlet, 10BASE-T1S, MCS low-level states and connector temperatures combine with project-specific power and cooling. You configure, measure and analyse the test in the EVCA workflow.

EVCA MCS test directions for vehicle, charging-station and controller development — **One MCS platform.** Two fundamentally different simulation directions. The same comframe data model follows both directions.

Vehicle DUT

MCS EV testing

Simulates the MCS charging station for EVCC (vehicle-side charging communication controller), charging subsystem and complete-vehicle tests. The MCS EVSE (charging station) simulator works with the cooled cable and external source required by the approved full-system test.

Cooled cable and connector temperature monitoring
External bidirectional source control

Charging-station DUT

MCS EVSE testing

Simulates 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.

The released MCS configuration correlates the following layers.

Low level

Charge Enable and ID

The system simulates and monitors Charge Enable and Insertion Detection according to the system scope.

Thermal

Plug and inlet temperature

Shows the temperature channels that protect the high-current connection and cooling architecture.

Auxiliary

EV and EVSE supply

Include the auxiliary voltage environment required by the selected MCS direction.

Physical link

10BASE-T1S

Measures and analyses the single-pair Ethernet environment below the application protocol.

High level

TLS, charging and BPT

Analyses secure communication and protocol-level BPT services. Physical reverse energy flow is a separate hardware configuration using suitable external source/load equipment; neither scope alone demonstrates complete bidirectional MCS system conformity¹.

High-power testing with detailed protocol analysis

Plan the power stage for maximum and continuous operation.

We 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. Device under test (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. MCS inlet and project-specific thermal architecture match 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.

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.

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.
