Portfolio-wide capabilities

Observe, Simulate and Analyse Charging Behaviour

Choose the task: record a real charging session, reproduce a charging partner, change a message or repeat a test series. Follow the matching capability to see how it works.

One technical foundation

Six actions. Different products. One decision chain.

A capability describes what the test must do. Product selection defines where that capability reaches the DUT (device under test) physically and which functions are released for the selected configuration.

Configure

Make test intent explicit

Connect DUT role, interfaces, parameters, automation and evidence requirements before hardware is selected.

Explore comframe
Simulate

Control counterpart behaviour

Challenge nominal, boundary and non-conform behaviour within the released product and protocol scope.

Professional Simulation
Measure

Keep physical and protocol layers together

Correlate communication, low-level signals, power and application states on one time base.

Explore EVCA
Analyse

Connect observation and expectation

Relate measured behaviour to the applicable technical rule and the exact released evaluation scope.

Automated Standards Analysis
Validate

Repeat an approved test method

Use versioned test logic, controlled configurations and explicit verdict boundaries.

Conformance Test Libraries
Preserve evidence

Keep result and configuration attributable

Carry test identity, measurements, decisions and reports into engineering, release or production workflows.

Charge Cycle Automation

Choose the physical domain

The capability stays clear while the DUT changes.

The same action can require a different product, interface and control model. These routes identify the correct starting point without implying that every capability is available in every configuration.

EV and EVSE development

EVCA + comframe

Communication, simulation, measurement, controlled faults, interoperability and released test logic.

Open the EVCA platform
Production and field

Easy Chester

Guided workflows for EOL (end-of-line), commissioning, service, inspection and calibration—using the control model appropriate to each product.

Choose the Easy Chester role
BMS testing

Battery Cell Simulator

Cell, sensor and fault simulation with an open interface. comframe is optional because many laboratories already operate another HiL (hardware-in-the-loop) environment.

Open BMS testing solutions
EV charging EMC

EMC Link

Keep charging communication observable across the chamber boundary while EMC stress is applied.

Control and integration

Use the software model that fits the operating environment.

comframe supports deep engineering analysis and extensibility for the compatible EVCA, Calimera and Battery Cell Simulator configurations.

Frequently asked questions

EV Charging and BMS Testing Capabilities FAQ

How are test results documented?

Available evidence can include configurations, measured values, communication traces, evaluations and reports. The exact output depends on the selected workflow.
