System of the Month May 2025: Easy Chester EOL – Precise EVSE end-of-line testing with maximum flexibility
The quality of Electric Vehicle Supply Equipment (EVSE) already starts in production. Before a charging station goes into operation, it must be comprehensively tested, precisely calibrated and reliably validated. This is exactly where the Easy Chester EOL from comemso comes in.
As a powerful system for end-of-line testing (EOL) of EV charging stations, Easy Chester ensures that each unit meets the highest requirements for quality, safety and compliance – including calibration in compliance with calibration law.
But the System of the Month May 2025 shows that standard solutions are only the beginning.
Individual EVSE test systems through seamless integration
In this customer project, Easy Chester EOL was expanded by a crucial component: The customer integrates its own, internally developed power electronics directly into the testing process.
Thanks to the Generic Source API with in the comframe software framework, customer-specific devices can be fully integrated and controlled in the test environment.
The result: a highly flexible, individually adapted EVSE test system that is precisely tailored to the production requirements.
Your benefits at a glance
With Easy Chester EOL and comframe, users benefit from a fully integrated inspection system:
- ✔Full end-of-line testing, tailored exactly to their setup
- ✔High-accuracy EVSE calibration (Eichrecht-ready)
- ✔Deep integration between hardware, software, and their own innovations
- ✔All controlled in one environment: comframe
This combination enables efficient quality assurance with a high degree of adaptability at the same time.
Rethinking EOL testing: Flexible, scalable, future-proof
With Easy Chester EOL, comemso offers more than just a testing device. The result is a scalable testing ecosystem that adapts to individual requirements and easily integrates future developments.
This flexibility is crucial, especially in the dynamic world of electromobility: manufacturers can contribute their own innovations without having to forego standardized test processes.
comframe: The central platform for your EVSE testing
The comframe software framework combines all components into a uniform solution. It enables:
- •Control of all test equipment
- •the integration of external systems
- •Automation of complex test sequences
- •Transparent and comprehensible documentation
This creates a consistent, efficient and safe test environment.
Conclusion: Tailor-made test systems for modern EV charging infrastructure
The project impressively shows how standardization and individualization can be perfectly combined. With Easy Chester EOL and comframe, customers get a solution that fully adapts to their processes – not the other way around.
