Test instrument for electric charging stations

  • Test instrument for electric charging stations
  • Test instrument for electric charging stations
  • Test instrument for electric charging stations
  • Test instrument for electric charging stations

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 is suitable for use in R&D and service applications.

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 thus 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
  • Technical characteristics
    • Connection option for a test consumer via an integrated earthing contact socket (230 V, max. 13 A)
    • Compact case, ideal for service calls
    • Large display for which background illumination can be activated
    • Selectable user interface language: D, GB, F, E, I, PT
    • Power supply via two 9 V (rechargeable) block batteries or power pack
    • USB data interface for firmware updates
  • Particularities

    Diagnostics information

    • Measuring parameter settings
