3.1 General description
By means of the EV tester / EV simulator, different functions of charging devices can be tested by simulating
the electric vehicle. EV testers are available both with firmly connected charging cable and type 2 charging
plug (acc. to IEC 62196, draft standard from Germany) and as version for the type 1 charging device with in-
tegrated charging jack (acc. to SAE J1772 respectively IEC 62196, USA, Japan).
The EV tester/simulator comprises the following functions:
•
Presetting of charging cable encoding for simulation of maximum charging current
•
Checking of PE connection between PWM and vehicle plug
•
Simulation of vehicle status B, C, D
•
Indication of PWM signal (CP test jack)
The device simulates both different operating modes of a connected electric vehicle and differently encoded
charging cables. In each case it only comes to a small power drain of approx. 3 mA for L1, L2 and L3 from
the connected charging device.
The simulation is only possible when the device is connected.
