About comemso
Independent development and manufacturing at comemso
Founded in 2009, comemso develops and manufactures test systems for electric-vehicle charging and battery management. The company is owner-managed, with development and production in-house.
A test task shaped the company
From a specialised test task to the first comemso system
Before founding comemso, Dr.-Ing. Kiriakos Athanasas and Dipl.-Ing. (FH) Anita Athanasas worked on specialised test systems at a major vehicle manufacturer. Suitable solutions were not available, while established suppliers considered the task too specialised and too complex.
Shortly after the company was founded, the planned reference project was cancelled during the financial crisis. Instead of waiting, the team invested in its own products, built prototypes and spoke directly with potential customers.
A year later, a customer requested an e-mobility test system. A prototype was ready within weeks and the complete test bench followed four months later. The first system remained in successful operation for more than eight years before becoming part of the customer’s museum.
comemso is investor-free, 100% owner-owned and owner-managed. Engineering, application teams and manufacturing work directly together, keeping product development and responsibility for quality in-house.

Investor-free since the beginning
Growth built on engineering, innovation and customer relationships
The company grew by solving demanding engineering tasks, reinvesting in its own development and working closely with system users.
Independent engineering. Personal responsibility.
Independence lets us invest in hardware and software development for the long term. Our teams take responsibility from the first idea through production and customer support.
- Investor-free and owner-managed
- Growth financed by the company’s own success
- Innovation developed and manufactured in-house
- Long-term decisions shaped by customer needs
Standards expertise
Turning standards knowledge into practical test methods
Co-founder Dipl.-Ing. (FH) Anita Athanasas contributes her e-mobility expertise to several standards working groups. Her work connects new requirements with practical test questions: what needs to be measured, how can it be challenged and how can the result be verified?
Standards expertise helps turn new requirements into executable test methods. Each method identifies the released standard edition, test-library version and customer specification.
Understand emerging requirements
Follow new interfaces and requirements early, while their technical details are being developed.
Develop the test method
Define observable states, timings, limits and fault conditions, then record the evidence.
Fast in-house implementation
Connect standards knowledge directly with hardware, software and production teams.
Company history
How the company and its test systems developed
Company founded in Ostfildern
Dr.-Ing. Kiriakos Athanasas and Dipl.-Ing. (FH) Anita Athanasas founded comemso GmbH in December. The name expresses the original focus: COMplex EMbedded SOlutions.
Battery Cell Simulator development
Development began on the first own product for testing battery management systems in electric vehicles.
Charging-system analysis
Devices for analysing and testing electric-vehicle charging systems became the second product family.
Expanded research and development
The company moved into a new research and development building next to the headquarters, increasing space for engineering and system integration.
Company group structured by purpose
Additional companies were established for distinct operating responsibilities. comemso GmbH changed into the holding company.
Self-generated renewable energy
A rooftop photovoltaic system began supplying renewable electricity to the company site.
Engineering, production and services in one group
The group connects product development, manufacturing, test and calibration services, and customer access in Germany and North America.
Independent recognition
Innovation is not a claim. It is the track record.
The awards recognise battery simulation, practical EVSE testing, entrepreneurship and the development of systems for new e-mobility requirements. EVSE means electric vehicle supply equipment, or charging station.
Recognition from the Esslingen district
Recognition for lithium-ion battery cell simulation for electric vehicles. It was an early external acknowledgement of the Battery Cell Simulator approach.
KfW GründerChampion for Baden-Württemberg
With its Battery Cell Simulator innovation, comemso was selected by KfW Bankengruppe as the state winner for Baden-Württemberg and presented at deGUT 2012.
Innovation Award Baden-Württemberg
The Battery Cell Simulator was recognised as an innovation that translated a complex e-mobility test requirement into a scalable technical system.
Innovation Award of the Esslingen district
Easy Chester received the Innovation Award of the Esslingen district for making professional charging-station testing practical in the field.
1st place. Landespreis für junge Unternehmen
The State of Baden-Württemberg and L-Bank awarded comemso first place in the 2020 state award for young companies.
TOP 100 Top-Innovator
The TOP 100 distinction recognised comemso’s innovation capability across the organisation.
Awards and quality documentation. Product and company awards document our innovations. ISO management systems, DAkkS accreditation, Eichrecht and CharIN evidence are listed under Quality & Certifications.
Company structure
Four operating companies. One specialised group.
comemso GmbH is the holding company. Four operating companies handle development and sales, production, testing and calibration, and customer access in North America.

How we engineer
Four principles that guide our engineering
Solve what the market cannot yet test
Begin with a test requirement that conventional instruments or standard products do not yet cover sufficiently.
Enter new technologies early
Work on protocols, power classes, battery management system (BMS) architectures and interfaces while they are still emerging.
Own the technical depth
Develop hardware, software, test methods and application knowledge together, so teams can observe and control the critical layers.
Build the benchmark for real work
Build systems that teams can use in research, validation, production, commissioning, service and metrology.

comemso has remained investor-free, owner-owned and owner-managed since 2009. Growth has been financed through the company’s own work and customer success.
What does developed and manufactured in-house mean?
Hardware, software, system design and production are handled within the comemso group. Teams can exchange findings directly and keep responsibility clear.
Does comemso test batteries?
comemso develops test systems for battery management systems (BMS). They replace real cells with safe, repeatable cell and sensor emulation for reproducible BMS tests. Electrochemical cell and battery-chemistry characterisation is outside this test scope.
Where can I verify quality and accreditation information?
You can find management-system certificates, laboratory accreditation and product-specific evidence on the Quality & Certifications page. Each document identifies its own scope.
