Easy Chester EOL integration

Released profiles, connected results.

Easy Chester EOL runs the approved test profile for the identified charger and links step results, measurements and the pass/fail verdict to its serial number, variant and configuration revision. Configure profile selection, sequence control, reporting and data handover for your production line.

Line-control, database, MES and QMS interfaces remain project-specific. The EVSE End-of-Line Testing application explains acceptance planning, cycle time and rework.

High-power test-cell architecture

Easy Chester EOL HPC: the EOL workflow at higher power.

EOL HPC adds the source, load, switching, protection and cooling required by the charger and production cycle to the shared charging test workflow.

Charging interface

Exercise the released connector, low-level states, communication and product parameters.

Safety controller

Coordinate the prerequisites, interlocks, switching state and cooling readiness before enabling the test under controlled conditions. Define how the system shuts down and reaches its safe state for the project.

Power hardware

Integrate source, load or bidirectional equipment for the defined operating points and duty cycle.

Production integration

Connect unit identity, sequence control, verdicts and reports to the production line through the released RS-232 interface and SCPI commands; higher-level factory interfaces remain project-specific.

Optional production metrology

Easy Chester EOL + Calibration keeps metrology evidence in the production record.

For reference comparison before shipment, Easy Chester EOL can be combined with the Calimera GUI and a project-specific AC or DC power meter. Keep the functional release and metrology-oriented verification linked to the same product identity.

For EOL HPC, coordinate reference measurement with the defined high-power operating points. Measurement range, uncertainty, traceability and the released calibration procedure must be specified for the production cell.

Power and test cell

Required operating points, source or load equipment, duty cycle, switching, cooling and safety interfaces.

Line-control and data interfaces

RS-232 with SCPI commands, unit identification, sequence control and result handover; MES and database integration remain project-specific.

Optional metrology

Calimera GUI, AC/DC power meter, measurement range, uncertainty, traceability and the approved procedure for the target market.

Frequently asked questions

Easy Chester EOL and EOL HPC questions

What is Easy Chester EOL?

Easy Chester EOL is the production-focused Easy Chester system for repeatable EVSE end-of-line testing. It executes approved function, charging communication and parameter checks, evaluates the result and connects the evidence to the tested product identity.

What does an EVSE end-of-line test verify?

It verifies the completed charging product or a defined production module against released factory acceptance criteria before release. The exact checks depend on the charger family, configured interfaces and test plan.

Can one system handle different charger variants?

Product and test configurations can be stored for different variants. The production identity or operator workflow selects the approved profile so the correct test logic is applied consistently.

How is the result linked to the manufactured unit?

The project can associate the test with approved identity fields such as serial number, variant, firmware, production order and timestamp. The exact database, MES, report and retention interfaces are project-specific.

Can Easy Chester EOL be integrated with line control or MES?

The production interface uses RS-232 with SCPI commands for straightforward line integration. Product identification, sequence control, result handling and any higher-level MES or factory interfaces are defined in the project scope.

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

Easy Chester EOL is the compact production path for repeatable EVSE function, communication and parameter verification. EOL HPC adds the project-specific source, load, cooling, switching, safety and high-power test-cell integration required by DC fast-charging products.

What is Easy Chester EOL HPC?

Easy Chester EOL HPC is the Easy Chester production system for repeatable end-of-line verification of DC fast-charging and high-power EVSE products. It coordinates charging-interface tests, safety-relevant production checks, external power hardware, automation and traceable results.

What can be the device under test?

The DUT can be the complete charger or a defined production module such as the charging outlet, communication controller, power stage or metering path. The exact boundary must be defined for the project.

Does Easy Chester EOL HPC have one universal voltage, current or power rating?

No universal combined rating should be inferred. Voltage, current, continuous and peak power, duration, energy, cooling and facility requirements are defined independently. Compatible hardware is selected through the approved project configuration.

Can the system test the charger at defined power operating points?

Yes, when the configured production cell includes the required source, load or bidirectional power hardware. The test sequence can establish approved operating points, verify the charger response and preserve the measurements and verdicts.

How does the system support safe high-power operation?

The production cell is configured around approved prerequisites, interlocks, switching, cooling readiness, controlled enable, emergency stop, shutdown and safe-state behaviour. Exact responsibilities and safety functions are project-specific.
