System of the Month August 2024: portable EVSE CCS tester
QuestionStart with the engineering problem
ContextConnect application, standard and product
SourceIdentify document and publication status
Next stepContinue to current technical scope

Some engineering teams need deeper charging communication access than a handheld functional tester but cannot move a full rack system to every site.

At a glance

  • Custom suitcase format
  • CCS communication testing
  • Mobile diagnostics
  • Customer-specific configuration

Why this mattered

Mobility normally forces compromises in interface access, measurement context or operator setup.

The system approach

The highlighted custom EVCA configuration placed the required CCS analysis and simulation functions into a compact transport case.

What the project shows

The project shows how a defined test boundary can be packaged for mobile use. Exact functions, power handling and connectors were customer-specific.
