Charging and measurement checks for production

The described production setup supports defined charging and measurement checks. The applicable conformity-assessment procedure determines how these checks are used and which records are required.

Measurements, test results and documentation

  1. Include the EVSE's power meter readings
  • The test report includes readings from the EVSE's own power meter for verification and documentation in the applicable German Eichrecht procedure.
  1. Compare readings with a calibrated power meter
  • A power meter calibrated according to ISO 17025 verifies the charging station's power and system measurements. Results are documented automatically so the team can compare reference values and identify deviations.
  1. Document functional and safety tests
  • The software supports functional and safety tests in the end-of-line process. It records test results, calibrations and proof of functionality.

Support production workflows and measurement quality

Automation and error analysis help the team run production tests and assess measurement quality.

For detailed conformance tests of communication and safety standards such as IEC 61851-1, DIN 70121, ISO 15118 and IEC 61851-23, use comemso EVCA with the appropriate hardware and software configuration. Easy Chester EOL provides the configured production checks described here.
