The test instrument is intended for examining the functional performance of charging stations for electric vehicles 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 is suitable for use in R&D and service applications.


Product Highlights

Complete 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
  • Easy operation and diagnosis
  • Compact, battery powered device, which is suitable for outdoor use


Status Visualization

Displayable Vehicle Statuses (CP)

  • No vehicle connected
  • Vehicle connected
  • Vehicle ready for charging without ventilation
  • Vehicle ready for charging with ventilation

Cable Type (PP)

  • No cable
  • 13 A cable
  • 20 A cable
  • 32 A cable
  • 63 A cable

Simulatable Errors

  • Short-circuited diode
  • CP-PE short-circuit
  • RCD tripped because I = 30 mA between L1 and PE
