3 Operating instructions
3.1 General description
By means of the EV simulator, the functions of charging devices for electric vehicles (charging stations, wall
boxes etc.) and pluggable charging cables (mode 3) can be tested by simulating the electric vehicle. After
installation or for service purposes, this is directly possible at the charging infrastructure.
The present version can be used for type 1 and type 2 charging devices, both with firmly connected charging
cable and with charging sockets and separate charging cable. By means of the provided measuring line, 4
different cable cross sections can be simulated.
The EV simulator comprises the following functions:
•
Measuring the built-in resistance inside the type 2 plug (between PP and PE)
•
Measuring the built-in resistances inside plug type 1 (between CS and PE) and
checking the interlock's switching function
•
Ampacity simulation of a charging cable
•
Checking the PE connection between PWM and vehicle
•
Simulation of a leakage current > 30 mA from L1 to PE
•
Simulation of vehicle status B, C, D and indication of charging voltage via LEDs
•
CP test jack for PWM signal
The device simulates both faults which can occur during normal use, and different operating conditions of an
electric vehicle. It only comes to a small power drain of approx. 3 mA from the connected charging device.
Additionally, a load current of max. 6 A can be drawn from the built-in Schuko socket via L1 or a test device
for RCD control can be connected.
Attention:
The Schuko socket shall only be used shortly for measuring purposes. Permanent usage is not allowed.
Furthermore, Walther offers EV simulators both as service-case version for type 1 or type 2 charging devices
with integrated charging jack (acc. to SAE J1772 or IEC 62196, USA, Japan) and with firmly connected
charging cable and charging plug type 2 (acc. to IEC 62196).
