Standards & Knowledge
Understand EV Charging and BMS Testing
Learn how vehicles, charging stations and battery controllers work together. Start with a practical question, then explore the measurements, test methods and standards behind the answer.
EVSE Calibration Methods
Understand controlled real-load calibration, repeatable operating points and the comparison between station and reference energy readings.
Explore EVSE calibration methodsFind your next technical reference
Start with your test question.
Browse by application, explore the relevant standard family or look up a technical term.

EV Testing
EV, EVCC (vehicle-side charging communication controller), BMS coordination, charging communication and complete-vehicle validation.
EVSE Testing
Charging-station development, conformance, high power, production, commissioning and operation.
BMS Testing
Cell, sensor, balancing and fault conditions for battery-management development and validation.
Interoperability & Charging Analysis
Real EV-to-EVSE behaviour, synchronised evidence, root-cause validation and field-to-lab reproduction.
MCS Testing
Communication, low-level states, temperature, cooling and high-power behaviour for megawatt charging.
EV Charging EMC Testing
Observe and maintain charging communication during conducted and radiated EMC testing.
03 / Standards & Knowledge
Understand the family. Then qualify the exact part, edition and test scope.
Find standards by document family, part, edition, DUT role and test objective. Consult the official standard for normative requirements.
IEC 61851
Conductive charging requirements, low-level signaling and DC EV supply-equipment context by part and edition.

MCS
Megawatt Charging communication, low-level signals, thermal context and related ISO 15118 services.
Charging EMC standards
IEC 61851-21-1 for the EV, IEC 61851-21-2 for off-board EVSE, UN R10 for vehicle approval, plus power-quality routes for harmonics and flicker.
EVSE field-safety context
Installation, protective measures and inspection context including IEC 60364, IEC 62196, VDE, DGUV, NEC, CEC and relevant UL routes.
EMC knowledge route
Separate the applicable standard, laboratory method, optical product and test intelligence.
Connect your EMC test objective with the applicable standard, laboratory method and optical interface. EMC Link transfers supported signals; the configured laboratory system performs the test.
Which document defines the test?
IEC 61851-21-1, IEC 61851-21-2, UN R10 and the relevant IEC 61000 power-quality route.
How is the charging EMC test planned?
DUT boundary, controlled counterpart, RF sequence, harmonics, flicker and synchronised evidence.
How is the chamber boundary implemented?
Transparent optical transfer of released charging communication and signal paths.
Who provides simulation and analysis?
EVCA and comframe provide the controlled charging partner, logging, correlation and system workflow.
04 / Standards & Knowledge
Three questions define three different test disciplines.
Understand the test method before choosing the tool
Conformance, interoperability and robustness complement each other. They do not become interchangeable because the same communication standard appears in all three.
Does one implementation meet defined requirements?
Structured testing uses defined requirements, preconditions and test cases for one implementation role.
Do independently developed implementations work together?
A real EV and EVSE can reveal combined timing, option and error-handling behaviour that isolated testing does not expose.
How does the implementation react at boundaries or faults?
Boundary values, delays, missing steps, non-conform behaviour and faults test the reaction beyond nominal operation.
Automated Standards Analysis
Correlate measured values, states, messages and timing with configured normative expectations.
Professional Simulation
Configure supported content, timing and difficult or non-conform charging-partner behaviour.
Charge Playback
Actively reproduce recorded charging-partner behaviour at the physical charging interface.
05 / Standards & Knowledge
Understand EV charging and BMS terminology.
Find definitions, common synonyms and related concepts for EV charging and BMS testing. Check the applicable standard for normative requirements.
06 / Standards & Knowledge
Explore technical guides, videos and downloads.
Find application notes, webinars, videos, checklists, brochures and datasheets in the Resources Library. Document dates and release status help you select the relevant technical reference.
Technical guide
Understand the test method and explore related technical guidance.
Application note or whitepaper
Deeper technical reasoning, configuration examples and methods for a defined problem.
Webinar or video
Expert explanation, workflow demonstration and recorded technical sessions.
Checklist

Brochure or datasheet
Current product scope, technical configuration and released specifications.
News or press release
Product developments and company news in their original publication context.
07 / Standards & Knowledge
Check the publication date, edition and release status.
Historical innovation evidence remains accessible, but it must not be confused with current product availability, released software or the valid test scope.
08 / Standards & Knowledge
Explore the applications, standards and products behind each test method.
Use these technical explanations to understand the method, then open the relevant product to check configuration, interfaces and available options.
Glossary
Definitions, synonyms and related concepts for EV charging and BMS testing.
Supported Standards
Standard family, parts, editions, status, test relevance and supported context.
Test Libraries
Implemented test cases for a defined standard, role, release and supported configuration.
Resources
Brochures, datasheets, application notes, webinars, videos and checklists with version control.
10 / Standards & Knowledge
Find the answer by test problem, standard or product.
Start with the engineering question
Choose your application to find the relevant standards, terminology, test methods, products and resources.
Regulatory knowledge
AFIR belongs between regulation, technical standards and operating evidence.
Use the AFIR route to identify what is legally required, what is implemented through technical specifications and what must be verified through EVSE, payment, backend, data or field workflows.
THREE STATUS QUESTIONS. NEVER MERGE THEM.
STANDARD STATUS
Is the document published, amended, superseded or draft?
Standards organisation
PRODUCT SUPPORT
Which hardware, interface, licence and release support it?
Approved product matrix
LIBRARY STATUS
Which cases, direction, scope and implementation are released?
Test Library matrix
A published standard does not automatically create product support or an executable Test Library.
EVSE calibration knowledge
Real load or phantom power?
Understand the measurement scope, the role of a controlled load and the operating points that matter for a repeatable EVSE calibration.
FAQ
Frequently asked questions
What belongs in the comemso Knowledge Center?
Find technical guides, standards information, application notes, webinars, videos and glossary definitions for your testing task.
Does this hub replace the applicable standards?
No. Web explanations and glossary definitions make the engineering context understandable. The applicable standard, part, edition, amendment, association document, product documentation and released test scope remain authoritative.
How is the hub different from the Resources Library?
The Knowledge Center explains testing topics and methods. The Resources Library provides documents, videos and recordings with publication dates and release status.
How is the hub different from the glossary?
Use the glossary to understand terms, abbreviations and synonyms, then explore the related applications and test methods.
Where should edition-specific requirements be checked?
Check the relevant standards overview and Test Library matrix. Confirm the document, part, edition, DUT role and released scope for your project.
