Germany-based comemso, which provides high-precision test and measurement systems for EVs, has introduced its Easy Chester Calimera, a high-precision, mobile, and scalable calibration device.
The device has a DC voltage range of 150-1,000 V and a current of up to 500 A, supporting a range of charging scenarios including 400 V and 800 V fast-charging systems.
The Easy Chester Calimera has an independent power supply, enabling it to operate up to eight hours autonomously with integrated battery and solar options. It can be easily mounted in vans or trailers, enabling multi-station calibration in a single day. Its modular design and quick setup are designed to reduce service interruptions.
Unlike traditional solutions, the Easy Chester Calimera uses battery emulation combined with resistive loads for measurement stability and repeatability, ensuring compliance with international regulations. The system is fully compatible with all the main EV charging protocols.
Equipped with comframe software, the Easy Chester Calimera provides real-time voltage and current monitoring, customizable test configurations, automated diagnostics and event logging and ISO 9001 and ISO 17025-compliant calibration PDF reports.
The Easy Chester Calimera is engineered for demanding environments, featuring advanced cooling technology for continuous high-performance operation and IP21 (active) and IP65 (inactive) protection, enabling reliable operation in temperatures from 0° C to 40° C.
The company recently integrated Megawatt Charging System (MCS) capabilities into its EVSE and EV test platform.
