Next stepContinue to current technical scope

A shared technical language and record structure help the team connect field failures and observations with high-power laboratory tests.

At a glance

  • Laboratory and field workflow
  • Published 1,000 V and 250 kW configuration
  • Battery emulation
  • Field data for HIL testing

Use field behaviour as a reference for laboratory tests

Recorded field behaviour gives engineers a reference for the original charging partner when defining controlled tests in the laboratory.

Connect field data with HIL testing

Recorded field data can guide HIL tests and reproduction workflows in the laboratory. The team can use the observations to define the behaviour it wants to investigate under controlled conditions.

Move from observation to repeatable investigation

The architecture links field observation with repeatable laboratory investigation. The 1,000 V and 250 kW battery-emulation values belong to the configuration featured in this project.
