EV Charger Testers for Installation, Production and Calibration

Choose a charger tester for installation and commissioning, maintenance and periodic inspection, production testing or energy-meter calibration. Easy Chester Micro combines AC installation, safety and communication tests in one compact device. Ultimate covers AC and DC field testing; EOL serves production and Calimera serves AC and DC calibration.

Easy Chester is designed for standalone operation without a laptop. Use the guided workflow on the device.

The goal of the Easy Chester hub

Turn an EVSE test task into a clear product decision.

Use the lifecycle stage to identify the relevant Easy Chester path, understand the five product roles and continue to the detailed technical specification.

Choose the smallest complete Easy Chester path for manufacturing, commissioning, service, inspection or calibration, then confirm the project-specific interfaces and ratings.

Selection principle. Lifecycle stage first. Product second. Exact interfaces, standards, power, safety, metrology and reporting scope third.
  1. 1
    Locate the task

    Factory, high-power production, commissioning, service, inspection or calibration.

  2. 2
    Select the product role

    EOL, EOL HPC, Micro, Ultimate or Calimera.

  3. 3
    Configure the released scope

    Technology, power, mobility, safety, metrology, automation and evidence.

Production application

Define the factory release process before selecting EOL or EOL HPC.

Start with the charger variants, acceptance criteria, cycle time, power boundary, automation, traceability and optional metrology. Select the Easy Chester product configuration second.

Open EVSE End-of-Line Testing

EVSE lifecycle testing

One charging station. Different evidence at every stage.

Manufacturing asks whether the unit can be released. Commissioning asks whether the installed charger is safe and functional. Service asks whether a fault was diagnosed and corrected. Calibration asks whether energy measurement remains traceable. The test method changes with the decision.

Easy Chester lifecycle from EVSE manufacturing and high-power end-of-line testing to commissioning, calibration, service and periodic inspection
The family is deliberately separated. Easy Chester does not compress production, field safety and metrology into one generic hardware claim. Each system is designed around a different operating decision.

Choose by task and environment

Five purpose-built EVSE tester paths.

Optional production metrology

Keep calibration evidence connected to the end-of-line result.

Easy Chester EOL and Easy Chester EOL HPC can optionally add a metrology-oriented workflow before the charging product leaves the factory. The configuration combines the production system with the Calimera GUI and a project-specific AC or DC power meter.

EOL option Easy Chester EOL + Calimera GUI + AC/DC Power Meter

Add reference comparison to the compact production workflow.

HPC option Easy Chester EOL HPC + Calimera GUI + AC/DC Power Meter

Add reference comparison to the high-power production cell.

Separate field product Easy Chester Calimera

Use the mobile product for calibration of installed charging infrastructure.

National legal-metrology requirements, approved procedures, measurement ranges, uncertainty, reference equipment and report formats remain market- and project-specific.

Optional end-of-line calibration workflow with charger, AC or DC reference power meter, Calimera GUI and report

Shared Easy Chester foundation

The product changes. The assurance logic remains recognizable.

Each system puts charging-specific test knowledge into a task-oriented workflow. The operator should not have to assemble unrelated tools and reconstruct the evidence after the test.

Guided workflows

Connect prerequisites, active test step, measured value, verdict and report.

Charging-specific depth

Combine the disciplines required by the task instead of presenting a generic electrical measurement alone.

Measurements linked to their test conditions

Keep the result connected to the tested charger, site, configuration or production identity.

Purpose-built roles

Preserve the difference between production release, field assurance and metrology.

Configuration inputs

Define six facts before selecting hardware and options.

The product family is selected by the real test boundary. A useful request describes the task, environment and evidence before it asks for a device name.

Lifecycle task Production, commissioning, service, inspection or calibration
Charging technology Connector family, communication and regional product variant
Power profile Voltage, current, power, duty cycle, duration and cooling
Operating environment Production line, high-power cell or installed charging site
Test depth Function, communication, safety, automation or metrology
Evidence and integration Report, unit identity, database, MES, QMS or calibration record
Selection of Easy Chester EOL, EOL HPC, Ultimate and Calimera by task, environment and evidence

Product-family boundary

Easy Chester standardizes operational EVSE testing. EVCA opens the engineering test space.

The right platform depends on whether the team needs a guided release or service decision, or an open development and analysis environment.

Frequently asked questions

Easy Chester EVSE tester questions

What is the Easy Chester product family?

Easy Chester is the comemso family of purpose-built EVSE testers for charging-station production, commissioning, service, inspection and calibration. The family contains separate systems for different lifecycle decisions rather than one universal device.

Which Easy Chester is used for charging-station commissioning?

Easy Chester Micro supports AC installation and commissioning. Easy Chester Ultimate covers AC and DC charging stations. Both combine guided charging-function, communication and electrical safety tests with reporting for the selected configuration.

Which system is used for EVSE maintenance and periodic inspection?

Use Micro for AC maintenance, repair verification and periodic inspection; choose Ultimate when DC charging stations are also in scope. Select the required interfaces, safety functions and reporting configuration.

Which Easy Chester is used for EVSE end-of-line testing?

Easy Chester EOL is the compact production path for repeatable function, communication and parameter verification with traceability. Easy Chester EOL HPC extends the production role to high-power charging products and project-specific power, cooling, switching and safety integration.

What is the difference between Easy Chester EOL and EOL HPC?

Easy Chester EOL focuses on repeatable production acceptance for charging products. EOL HPC is selected when the production cell must coordinate high-power operating points, external source or load hardware, cooling, interlocks and safely sequenced automation.

Can calibration be added to Easy Chester EOL or EOL HPC?

Yes. Both production systems can optionally be combined with the Calimera GUI and a project-specific AC or DC power meter. This connects metrology-oriented checks with the same unit identity and production evidence.
