Since 2016, the Easy-Chester product family has been supporting professionals worldwide in the reliable testing of AC and DC charging stations. What began as a compact solution for mobile use has established itself worldwide as a reference for standard-compliant testing. Now comemso, technology leader in the field of charging infrastructure testing, is introducing the next generation: the Easy Chester Gen. 2.
The Easy Chester is a mobile functional test device for AC and DC charging stations that fully simulates the communication of an electric vehicle - without the need for a real vehicle. It supports all relevant communication protocols: DIN 70121, ISO 15118, IEC 61851-1 for CCS and NACS charging standards as well as CHAdeMO up to and including version 2.0.
Typical application scenarios range from initial commissioning and recurring tests as part of quality assurance to maintenance, troubleshooting and technical support or the repair of charging stations. With the Easy Chester, the function, communication and safety behavior of a charging station can be tested easily and safely - wherever it matters.
With the new Easy Chester Gen. 2, comemso now presents a more powerful, even more flexible system with numerous extensions:
The official sales launch of Easy Chester Gen. 2 begins today.
With this further development, comemso is consistently continuing its course of innovation - and remains true to its own claim: First on the market. First on innovation.

With the new Easy Chester Gen. 2, comemso now presents a more powerful, even more flexible system with numerous extensions:
- A revised, more intuitive user interface ensures even easier operation.
- In addition to 400 V systems, 800 V charging systems can now also be tested - a crucial step for testing modern high-power chargers.
- The Pro version allows DC load simulation with up to 60 kW.
- Proven features are retained: extensive long-term tests and targeted fault simulations - e.g. communication faults or insulation faults (AC/DC).
- With the optional comISO module (available from Q4/2025), additional VDE-compliant tests can also be carried out.
