Electric Vehicle EV Tester / EV Test Instrument for charging plugs type 1 and 2 /
PP and CP simulation /
Shock-proof socket connection / Direct acceptance of all connections via laboratory plugs

Electromobility is playing an increasingly important role. An important point here are the charging stations for electric vehicles. Special measuring devices are needed to check the function, protective devices and insulation of permanently installed charging stations, also known as wallboxes. Often, measuring devices are already available to perform the required measurements. An EV test instrument is therefore required so that the measuring device can be connected to the charging station.

The EV test instrument is specially designed for this application and already comes with a variety of functions. For example, all lines leaving the charging station are output individually via laboratory plugs. Thus, all lines can be tapped via the EV test instrument. This allows the charging station to be checked for insulation with the help of the EVSE adapter. The EV test instrument has a shock-proof plug connection. The EV test instrument can be used to check the residual current device.

A charging cable not only contains the supply lines for charging an electric vehicle, but also two interfaces. The electric vehicle communicates with the charging station via the CP line (Control Pilot) and communicates the current status of the electric vehicle. The PP line (Proximity Plug) is used for communication between the connected charging cable and the charging station. The charging cable can thus tell the charging station how many amps it may be loaded with. To test both functions, the EV test instrument is equipped with corresponding simulators.
