BENNING EV 3-2 15 Pin assignment Figure 2: Assignment of the Type 2 connector for connection to the charging station (EVSE) 4.2 Functions The device is intended for the following tasks: • Simulating an electric vehicle (EV) for the charging station • Providing safe contacting for the installation tester The simulation of the charging cable and electric vehicle used is done via the rotary switches “PP-Status/State” and “CP-Status/State” of the device. Rotary switch “PP-Status/State” for cable simulation With the rotary switch “PP-Status/State” you can simulate different codings of the charging cables. The coding describes the maximum permissible current carrying capacity of the charging cable. By means of the switch position, different resistance values are switched in the device between the PP and PE contacts. Switch position Simulation Resistance (PP-PE) N.C. No charging cable connected or error.

BENNING EV 3-2 16 Rotary switch “CP-Status/State” for vehicle simulation With the rotary switch “CP-Status/State” you can simulate different vehicle conditions. By means of the switch position, different resistance values and a diode are switched in the device between the CP and PE contacts. The communication signal (CP signal) is intended to control the charging process between the charging station and the vehicle (EV). For this purpose, the charging station applies a square- wave signal of 1 kHz to the CP contact of the charging plug. Depending on the operating status, the PWM (pulse width modulation) signal is loaded differently by the vehicle and its amplitude is changed. Switch position Simulation Description Resistance (CP-PE) PWM voltage at CP contact A No vehicle (EV) connected. No power supply from charging station. Open ±12 V, 1 kHz B Vehicle (EV) connected but not ready for charging. Charging station detects vehicle, but no power is provided. 2 740 Ω +9 / -12 V, 1 kHz C Vehicle (EV) connected and ready for charging. Ventilation of the charging area is not required. Charging station provides power supply for vehicle. 882 Ω +6 / -12 V, 1 kHz D Vehicle (EV) connected and ready for charging. Ventilation of the charging area is required. Charging station provides power supply when ventilation of the charging area is given. 246 Ω +3 / -12 V, 1 kHz E Error, short-circuit CP- PE via internal diode. Charging station stops the power supply and unlocks the charging cable within 30 s. - - Table 5: Switch positions of the “CP-Status/State” rotary switch Recommended test sequence • Switch positions A-B-C: simulation of the charging process without ventilation of the charging area • Switch positions A-B-D: simulation of the charging process with ventilation of the charging area • Switch position E: error simulation

5178 / 03/2021 en BENNING EV 3-2 17 5 Operation You can perform tests with an installation tester [} page 17] or an oscilloscope [} page 18]. 5.1 Testing with an installation tester Requirements • BENNING installation tester With the device alone (without installation tester) you can only check the functions of the PP signal and CP signal of the charging station (EVSE). • Charging station (EVSE) compatible with the device NOTE Test socket You can only test the phase L1 of 3-phase charging stations (EVSE) via the test socket of the device. 1 2 3 Figure 3: Connecting the device 1 BENNING installation tester 2 BENNING EV 3-2 3 Charging station (EVSE)

Operation 5178 / 03/2021 en BENNING EV 3-2 18 Procedure 1. Connect the installation tester to the device via the test socket or the 4 mm test sockets. 2. Select the desired positions of the rotary switches. – “PP-Status/State”: switch position “N.C.” – “CP-Status/State”: switch position “A” 3. Connect the device to the output of the charging station (EVSE) via the Type 2 connector. 4. Use the installation tester to perform the prescribed safety tests in a voltage-free condition at the output of the charging station (EVSE). 5. Simulate the different charging states using the switch positions of the rotary switches “PP- Status/State” and “CP-Status/State” and check the feedback from the charging station (EVSE). 6. Use the installation tester to perform the prescribed safety tests at the output of the charging station (EVSE) with the mains voltage being applied. For this, select the desired positions of the rotary switches at the device. – “PP-Status/State”: switching position according to the maximum charging current from 13 to 64 A – “CP-Status/State”: switch position “C” or “D” 7. Before disconnecting the device from the charging station (EVSE), set the rotary switch “CP-Status/State” to the switch position “A”. 5.2 Testing with an oscilloscope You can measure the CP signal of the charging station (EVSE) with an oscilloscope via the BNC socket of the device. Via the duty cycle, the charging station (EVSE) gives the electric vehicle (EV) the maximum current value that can be drawn from the charging station. For further information, refer to Table A7 of DIN EN 61851-1 (VDE 0122-1). • D: Duty cycle • PW: Pulse duration • T: Period duration

5178 / 03/2021 en BENNING EV 3-2 19 Requirements • Oscilloscope (probe: 10:1, input resistance: 10 MΩ) • Charging station (EVSE) compatible with the device NOTE Oscilloscope • Using a 1 MΩ input resistor instead of the recommended 10 MΩ will reduce the amplitude of the CP signal by approx. 17 % compared to the actual value. • Compensate the oscilloscope and probe for correct signal representations. • It is recommended to use a portable and battery-operated oscilloscope. WARNING Dangerous voltage Danger to life or serious injury is possible due to contact with high electric voltage. An existing 50 Hz / 60 Hz interfering signal can be suppressed by connecting the 4 mm PE test socket of the device to the earth connection of the oscilloscope. • Make sure that there is no dangerous voltage potential at the PE contact of the charging station (EVSE). • Use safe accessories. Procedure 1. Connect the oscilloscope to the device via the BNC socket. 2. Select the desired positions of the rotary switches. – “PP-Status/State”: switch position according to the desired coding of the charging cable (maximum current carrying capacity) – “CP-Status/State”: switch position “A” 3. Connect the device to the output of the charging station (EVSE) via the Type 2 connector. 4. Simulate the different codings of the charging cables. For this, select the desired positions of the rotary switches at the device. – “PP-Status/State”: switch position according to the desired coding of the charging cable (maximum current carrying capacity) – “CP-Status/State”: switch position “B” or “C” 5. Check the waveform and amplitude of the CP signal on the oscilloscope. If necessary, repeat the test for other codings of the charging cable. 6. Before disconnecting the device from the charging station (EVSE), set the rotary switch “CP-Status/State” to the switch position “A”.
