Comemso presents new calibration solution for charging stations

German electronics firm Comemso presented the Easy Chester Calimera, a high-precision, mobile and scalable calibration solution for EV charging stations, according to the company. The device is designed to simplify and optimise calibration processes and make them future-proof.

With a DC voltage range of 150 to 1,000 volts and a current of up to 500 amps, it supports a wide range of charging scenarios, including 400 V and 800 V fast charging systems. This means that the Easy Chester Calimera can be used to calibrate everything from public AC charging points to modern fast chargers.

The system was developed as a global solution and supports charging stations with CCS (DIN 70121, ISO 15118-2, ISO 15118-3), ChadeMo (versions 0.9-2.0) and the NACS (SAE J3400) for DC charging as well as AC tests according to IEC 61581-1 and SAE J1772 with up to 32 amps three-phase or 80 amps single-phase. “These features allow users to optimize testing workflows, ensure compliance, and streamline reporting,” Comemso explained.

The Easy Chester Calimera is designed as a mobile calibration solution and can be operated autonomously for up to eight hours with the integrated battery and PV system. Thanks to its compact dimensions, the solution can be easily installed in a van or on a trailer. Thanks to the ease of transport, it should be possible to calibrate several charging stations per day, according to the company. With protection class IP21 (active) and ID65 (inactive), reliable operation should be possible at temperatures from zero to 40 degrees Celsius.

On the software side, the device utilises the ‘comframe’ software developed by Comemso. This is designed to offer real-time voltage and current monitoring as well as customisable test configurations. Diagnostics and event logging are automated and the PDF reports are ISO 9001 and ISO 17025 compliant. “These features allow users to optimize testing workflows, ensure compliance, and streamline reporting,” Comemso wrote.

Unlike traditional solutions, the Easy Chester Calimera utilises battery emulation in combination with resistive loads for exceptional measurement stability and repeatability, ensuring compliance with international regulations, according to Comemso.
