Charging and BMS test software
comframe: charging expertise in your daily test workflow
Bring charging expertise into your daily test workflow with comframe: configure charging, calibration and battery management system (BMS) tests. Review the deviations highlighted by the software and investigate the response with Professional Simulation. ISO 15118-4/-5 SECC TestLibs are already available.
The comframe workspace
Simple to use. Powerful in the details.
Arrange the workspace around your test task. Use simple window controls to keep the relevant functions in view and open the technical detail when you need it.
- 1Partner request: charging-message sequence.
- 2Device response: synchronised voltage and current traces.
- 3Result record: decoded messages and event data.
One software framework for connected test applications.
Use the same workspace with the test system your task requires.
Use comframe to develop and validate EV charging, interoperability, EVSE calibration and battery management systems. Work in a consistent workspace with your supported EVCA, Calimera or Battery Cell Simulator (BCS) configuration.
EV, EVSE, interoperability, high-power, MCS and communication-focused test systems.
Mobile calibration and metrological verification at the charging station.
Cell, sensor, balancing, isolation and fault scenarios for BMS validation.
- 1Test requirement: cell and sensor setpoints and measurement data.
- 2Response: the measured signal in the oscilloscope view.
- 3Fault Injection: configure isolation faults between DC+ and PE and DC- and PE for IMD test
Purpose-built software
Application knowledge built into the workflow.
Configure the device role and test conditions, then review messages and measured signals together. Save the configuration, measurements and report so colleagues can review the same run. Use the implemented application functions and add project integration through released interfaces.
Projects & configurations
Keep the DUT, role, standards, behaviour, enabled functions and evidence requirements in the project configuration.
Synchronised data
Correlate protocol, low-level states, traces, measurements and relevant electrical behaviour on one time base.
Visualization & reports
Review measurements and highlighted deviations in views suited to the test task. Link the outputs to the run that produced them.
Automation & interfaces
Reuse approved configurations in cycles, campaigns, production processes and external orchestration.
Arrange, save and share your workspace.
Set up a workspace and share it with your team.
Arrange views in a few clicks, resize them proportionally and save the layout. Share the view configuration with colleagues so they can load the same workspace directly.
Arrange views for the task
Arrange messages, measurements, controls and results together. Move and resize the views to suit the current test.
Set up CAN and Ethernet directly
Configure the supported CAN and Ethernet hardware in the application workflow, with the settings needed to connect your test equipment.
Live and logging controls remain visible
See and change the live/logging mode with the compact controls at the bottom left of the workspace.
Decide what to keep after the charging stop
After a charging stop, comframe asks whether to keep the measurement. If you do not respond within the timeout, it saves automatically. The file name includes context from the activity to help identify the recording.
Shared software core and application-specific logic
Shared software core with charging and BMS modules
The generic core keeps projects, synchronised data, visualization, reports, automation and interfaces consistent. Domain modules add the engineering context for CCS and NACS paths, CHAdeMO, GB/T, MCS and BMS. Supported systems include EVCA, Calimera and Battery Cell Simulator.
One platform. Three charging perspectives.
Measuring, analysing and testing across real-pair, EV and EVSE workflows.
Applicable EVCA configurations use the same software environment whether the engineer observes two real charging partners, tests an EV against an EVSE (electric vehicle supply equipment, or charging station) simulation or tests an EVSE against an EV simulation.
Analysis, simulation and automation
comframe functions for your test workflow.
Automated Standards Analysis
Relate measured values, timings, states and messages to normative expectations and highlight meaningful deviations.
Professional Simulation
Configure supported message content, timing, optional communication and exceptional behaviour without developing the complete test environment.
Manipulating Gateway
Modify selected communication between a real EV and real EVSE to investigate a root-cause hypothesis during charging.
Charge Playback
Import supported recordings into comframe for analysis now. Replaying recorded EV behaviour as an EV simulation with Charge Playback in comframe is planned for Q1/2027.
Charge Cycle Automation
Sequence saved configurations into repeatable cycles, campaigns, regression runs and production workflows.
Conformance Test Libraries
Execute released test logic for a defined standard, edition, DUT role and validated or approved scope.
Released in comframe
From SECC test selection to a documented result.
Use the ISO 15118-4 and ISO 15118-5 TestLibs for AC and DC EVSE communication in comframe. Compare the Test Library scope and software status with your DUT features and EVCA configuration to identify the applicable test cases.
Use PICS to describe supported features and PIXIT to set the parameters required for execution.
Select the test cases that apply to the DUT and the released test-library package.
Execute the selected tests in comframe and inspect the automatic evaluation alongside the recorded communication.
Use individual test-case reports to review the result and document the test evidence.
- 1Test requirement: selected case, PICS and PIXIT.
- 2Device state: live CP, PP, AC/DC voltage & current values as well as temperature in the status bar.
- 3Result workflow: Test Procedure; no verdict is visible in this capture.
Integration & APIs
Run tests in comframe and connect external systems through released interfaces.
Match integration depth to your engineering process. External systems can coordinate the implemented charging or BMS workflow while the application logic stays in comframe.
Native comframe workflow
Configure, run, analyse and document the test directly in comframe for engineering work and controlled manual operation.
REST API orchestration
Use released interfaces to select approved configurations, trigger workflows and monitor defined states. Retrieve results linked to the test; Python applications can act as REST clients.
Project-specific integration
Connect applicable HiL systems, test benches, CI/CD pipelines, external power or measurement equipment and quality systems. Define responsibility for control and safety at each interface.

Existing recordings and planned extensions
Analyse existing measurement recordings
Available now: use the recording import in comframe to analyse supported measurement files.
Planned for Q1/2027: replay recorded EV behaviour as an EV simulation with Charge Playback in comframe. The remaining CCS TestLibs are targeted for the end of 2026, with Q1/2027 allowed if validation takes longer.
IEC 61851-23: the comemso TestLib has been demonstrated. Its port to comframe is prepared; a comframe release is not yet available.
See the current IEC test setupSupport for importing EV DBC files for EV-CAN data and for LIN data is planned during 2027. The released version defines which integrations you can use today.
