Diagnostics Unit for Testing Type 2 Electric Charging Points

  • Diagnostics Unit for Testing Type 2 Electric Charging Points

The test instrument is intended for examining the functional performance of charging stations with type 2 connector socket (mode 3 charging). The test instrument is connected to the charging station to this end, in order to document communication between the charging station and the test instrument. If the charging process doesn’t start, the source of error can be quickly pinpointed.

The PROFITEST H+E BASE 32 is suitable for use in R&D and service applications.

Diagnosis of electric charging stations with a single test instrument:

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

Error simulations:

  • Short-circuiting of the diode in the vehicle’s circuit
  • Short-circuit between CP and PE
  • Testing of the RCD by tripping and measuring breaking time
  • Indication of states by means of easy-to-understand symbols
  • Simple operation and diagnostics
  • Compact, battery powered device and thus suitable for outdoor use

Product Highlights

Connection option for a test consumer via an integrated CEE outlet (400 V, max. 32 A)
