Czech Metrology Institute uses comemso mobile calibration solution for charging infrastructure
Easy Chester Calimera has been integrated into CMI’s service vehicle and is already actively used for AC and DC charging station calibration in the field
(PresseBox) - The Czech Metrology Institute (CMI) is now working with the comemso Easy Chester Calimera mobile calibration solution. The system has not only been selected, but has already been delivered, professionally integrated into CMI’s own service vehicle, and is actively in use.
By investing in the Easy Chester Calimera, CMI is strengthening its capabilities for mobile calibration of AC and DC charging stations directly in the field. As the national metrology authority of the Czech Republic, CMI plays a key role in ensuring measurement accuracy, compliance and trust in calibration- and metrology-related applications.
With the Calimera solution integrated into its service vehicle, CMI can verify charging stations directly where the energy actually flows: at the charging point itself. This supports precise and traceable verification of delivered energy and contributes to accurate billing, regulatory compliance and trust in public charging infrastructure.
From live demonstration to mobile calibration vehicle
The project was implemented in close cooperation between CMI and comemso. In December 2025, the comemso team visited CMI in Prague to demonstrate the Easy Chester Calimera using the comemso demo vehicle. During the visit, additional CMI experts and international partners had the opportunity to experience the system live in operation.
Following the demonstration, CMI provided its own service vehicle, into which comemso professionally integrated the Calimera solution. In February 2026, the fully equipped vehicle was handed over at comemso. The handover also included joint system training before CMI drove the vehicle back to Prague on the same day.
“This project clearly demonstrates the importance of practical and mobile calibration solutions for the further development of charging infrastructure,” says Dipl.-Ing (FH) Anita Athanasas, Chief Commercial Officer (CCO). “We are very pleased that CMI is already actively using the Easy Chester Calimera and that our technology can contribute to reliable measurement technology in the field of e-mobility.”
Mobile calibration under real-world conditions
The Easy Chester Calimera is a mobile in-field calibration system for charging infrastructure. It enables precise and traceable measurements on AC and DC charging stations and is designed for use under real-world conditions. The system supports calibration-compliant testing processes in accordance with ISO/IEC 17025 and is suitable for applications in the field of legal metrology.
Key features include a wide voltage and current range for modern high-power charging applications, high-precision energy measurement for AC and DC charging systems, automated workflows, and support for common charging standards such as CCS1, CCS2, CHAdeMO, NACS and AC Type 1 / Type 2.
For operators, testing organizations and authorities, the correct measurement of charged energy is becoming increasingly important. Only when charging stations measure accurately can end users trust that they are billed for exactly the amount of energy they actually receive.
A strong signal for the market
CMI’s active use of the Easy Chester Calimera underlines the growing demand for reliable, mobile and field-ready calibration solutions for charging infrastructure. As public and commercial charging networks continue to expand, measurement accuracy, traceability and regulatory confidence are becoming increasingly important.
