Also specify operating points, duty cycle, switching and cooling.
Explore the higher-power configurationLink each test result to the manufactured unit.
Run the approved test profile for the identified charger. Easy Chester EOL links step results, measurements and the pass/fail verdict to its serial number, variant and configuration revision. Match profile selection, sequence control, reporting and data handover to your production line.
Specify the line-control, database, MES and QMS interfaces for your project. The EVSE End-of-Line Testing application covers acceptance planning, cycle time and rework.
Extend the production test to higher power with Easy Chester EOL HPC.
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.
Size the test cell for your charger and production cycle.
Specify electrical, thermal, timing and facility requirements for the DUT and production cycle separately.
Combine production test results and calibration evidence in one record.
Add the Calimera GUI and a project-specific AC or DC power meter to Easy Chester EOL for a reference comparison before shipment. Link functional release and metrology-oriented verification 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.

Configure hardware and interfaces for your test plan.
Use the production requirements checklist to define acceptance, cycle time and evidence. These inputs determine the EOL configuration:
Complete EVSE or defined module, connector families, charging technologies, firmware and market versions.
Required operating points, source or load equipment, duty cycle, switching, cooling and safety interfaces.
RS-232 with SCPI commands, unit identification, sequence control and result handover; MES and database integration remain project-specific.
Calimera GUI, AC/DC power meter, measurement range, uncertainty, traceability and the approved procedure for the target market.
Easy Chester EOL and EOL HPC questions
What is Easy Chester EOL?
Easy Chester EOL runs repeatable EVSE end-of-line tests in production. It performs approved function, charging communication and parameter checks, evaluates the results and links 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?
Store product and test configurations for the charger variants. Select the approved profile through the production identity or operator workflow to apply the matching test logic 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?
Define the DUT as the complete charger or a production module such as the charging outlet, communication controller, power stage or metering path. Specify the test boundary 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.
