The Easy Chester Calimera – Setting the Standard in EVSE Calibration
The success of e-mobility depends on trust, precision, and standard compliance. As charging technology advances, ensuring that EV charging stations meet regulatory requirements becomes more critical than ever. The Easy Chester Calimera is designed to simplify, optimize, and future-proof calibration processes by providing a mobile, high-precision, and scalable solution for EVSE professionals.
High-Power, All-Standards Capability with Proven Measurement Stability
With an extensive DC voltage range (150V – 1000V) and current capacity (0A – 500A or more), the Easy Chester Calimera supports a wide range of charging scenarios, including 40 kW, 130 kW, and 260kW configurations. This ensures compatibility with 400V and 800V charging systems, aligning with the latest industry standards.
Unlike traditional calibration tools, resistive loads ensure highly stable and repeatable measurement conditions. This approach minimizes deviations and guarantees accurate, regulation-compliant data, making the Easy Chester Calimera a more reliable alternative to battery-based or electronic load solutions.
Comprehensive Standard Compatibility
Designed to meet global standards, the Easy Chester Calimera supports:
✔ CCS (DIN 70121, ISO 15118-2, ISO 15118-3)
✔ CHAdeMO (Versions 0.9 – 2.0)
✔ NACS (SAE J3400)
✔ AC Testing (IEC 61851-1 & SAE J1772, up to 32 A 3 phases or 80 A one phase)
This ensures full interoperability with the latest and most widely used EV charging protocols worldwide.
Designed for Mobility & Efficiency
As a fully mobile calibration solution, the Easy Chester Calimera is built for on-site operation:
✔ Independent power supply – Integrated battery and solar options allow for up to 8 hours of autonomous operation.
✔ Compact and transportable – Easily mountable in vans or trailers, allowing calibration of multiple charging stations in one day.
✔ Minimized downtime – Modular components and a quick setup process reduce service interruptions.
Built for the Most Demanding Environments
Durability is key for field operations. The Easy Chester Calimera features:
- Advanced cooling technology for consistent performance under high loads.
- IP21 (active) and IP65 (inactive) protection for operation in challenging conditions (0°C – 40°C).
Setting a New Benchmark in EVSE Calibration
With German-engineered precision, modular scalability, and a proven track record since 2016, the Easy Chester Calimera is the go-to solution for calibration professionals worldwide. It ensures that charging stations remain compliant, efficient, and future-ready, helping to build trust in the EV infrastructure.
Powerful Software for Maximum Control
The comframe software enhances efficiency with:
✔ Real-time monitoring of voltage and current
✔ Customizable test configurations
✔ Automated event logging & diagnostics
✔ Detailed measurement and reports (ISO 9001 & ISO 17025)
This provides full transparency and traceability, ensuring compliance with global quality and calibration standards.
