Communication tester between the charging station and the electric vehicle

  • Communication tester between the charging station and the electric vehicle

The test instrument is used for the testing of the communication between the charging station and the electric vehicle – with type 2 connector socket (mode 3 charging).

The test instrument is connected between the charging station and the electric vehicle, in order to document communication between the station and the vehicle. If the charging process doesn’t start, the source of error (charging station or electric vehicle) can be quickly pinpointed. The PROFITEST H+E TECH is suitable for use in R&D and service applications.

Complete diagnosis of electric charging stations and electric vehicle:

  • Vehicle states
  • Cable condition
  • Error states
  • PWM signal evaluation
  • Phases and phase sequence
  • Battery level

Displays communication between the charging station and the electric vehicle in real-time.

Indication of states by means of easy-to-understand symbols

Easy operation and diagnosis

Compact, battery powered device, which is thus suitable for outdoor use
