3 Appropriate utilization

The PLC-Tracer was built according to applied safety- and technical norm. Yet, improper use may leads to severe dangers for the user or thirds, or malfunctioning of the device and damage to other property. As a testing environment for simulating and analyzing data of an E-Vehicle during the process of charging the PLC-Tracer can be plugged to a charging station instead of an actual E-Vehicle in order to simulate said.

Operating the PLC-Tracer requires general safety knowledge in handling electric devices and the charging process of E-Vehicles according to Norm IEC 61851. The procedure of the charging process itself is NOT being displayed in this document explicitly.

The PLC-Tracer is meant for industrial usage in science, development and field operation only. Part of the ordinary field of application also accounts:

• The usage according to the performance restrictions, listed in the technical Data.

• The usage in the manner as is depicted and described in this abbreviated manual. Operation and usage outside of these restrictions is improper. Damage resulting from improper operation or usage will not be covered by hse-electronics GmbH. The risk is solely carried by the operator. The operator is not permitted to modify, dis- or reassemble the device in any way, unless specifically and written permitted by hse-electronics GmbH.

4 PLC-Tracer Hardware

By developing the PLC-Tracer, hse-Electronics GmbH introduced a system for emulating electric vehicles (EV) and charging stations (EVSE), which allows for comfortable testing of charging stations and electric vehicles. To conductively charge an EV at a charging station there has to be a charging supply line and a data connection between the two components. EVs and EVSEs communicate via a data line, integrated in the supply line. (CP = Control Point). As a carrier for data between EV and EVSE a 30 MHz modem signal, modulated to a 1 KHz PWM-Signal, is being used.

4.1 Main features of the PLC-Tracer

The PLC-Tracer mainly consists of the following functional blocks: EV-Simulation Simulation of an EV on data level in order to test EVSEs (according to

IEC 61851 / SAE J1772:2001 / ISO 15118 EVSE-Simulation Simulation of an EVSE on data level in order to test EVs

(according to data level IEC 61851:2001 / ISO 15118) EV-EVSE-Data-Monitoring Monitoring of data traffic between EV and EVSE EV-EVSE-Data-Manipulation Allows for manipulation of PLC data

4.2 Composition, Connector, Buttons and Displays

The PLC-Tracers hardware composition is divided in two groups:

The charging current part is located in the rear, yellow section of the case.

The control and analysis units are located in the front, black section of the case. By dividing the charging current part, with its high currents and voltages, from the control and analysis units a maximum level of operation safety is attained.

5.2.6 SLAC

The SLAC (Signal Level Attenuation Characterization) function serves as a mean for definite identification of all in the communication involved components. (EV and EVSE). This function has to be activated before implementing the analysis process. This way requirements for the initiation of a data connection are met. Manual SLAC With the manual SLAC (SLAC EV or SLAC EVSE) a data layer only SLAC session is started. PWM values have to be adjusted manually. (Q.v. Chapter 5.1.1 respectively 5.1.3) Automatic SLAC If automatic SLAC (Initialize SLAC and SLAC EV&EVSE) is selected the necessary PWM settings are set automatically. The execution has to be in order as follows, to allow for a flawless process:

1. EV and EVSE are not connected to the Tracer 2. Press Initialize SLAC and wait for the initialization to finish 3. Connect the vehicle to the EV side 4. Connect the charging station to the EVSE side 5. Press SLAC EV&EVSE

Explanation: After pressing the Initialize SLAC button the PWM Bridge is deactivated, the vehicle on the EV side will get 100% PWM, the charging station on the EVSE side +12V regardless of what EV or EVSE are transferring. Now EV and EVSE can be plugged safely. They will not connect yet. After pressing the SLAC EV&EVSE Button the SLAC process will start. First the SET_KEY command will be send to the EV side. The SET_KEY command requires a restart of the QCA-7000. This will be initiated automatically. After approx. five seconds State B (9V) is set on the EVSE side and the CM_SLAC_PARM.REQ is being sent. The EVSE should start the SLAC process. Once the SLAC process is done, the PWM Bridge is being reactivated, meaning the PWM data are being sent from the EV side as well as the EVSE side. Usually the EV should set State B (9V) and the EVSE should set 5% PWM. Now the EV should start the SLAC process. The tracer awaits the CM_SLAC_PARM.REQ and responses to the SLAC commands sent by the EV. When both sides are linked successfully, the V2G communication starts. The EVCC should send the SECC Request.

5.2.7 Troubleshooting

Stop during the SECC Discovery Request After the automatic SLAC process of the EVSE, the PWM Bridge is being reactivated. If no EV is plugged to the PLC-Tracer, +12V are sent to the EVSE on PWM level. The EVSE unlinks the PLC-Tracer. If an EV is plugged to the PLC-Tracer afterwards the EVCC searches the SECC by sending multiple SECC Discovery Requests, but fails due to the unlinked EVSE. Solutions:

1. The checkbox If no car is connected, simulate State B to EVSE, to be located in the menu Settings -> CP-Mapping of the EV-EVSE-PWM software has to be activated. (Q.v. 5.1.7)

2. Connect the EV before the SLAC process is initiated and keep connected, until the process is done.

EV connects directly to the EVSE without PLC-Tracer According to DIN70121:2012-01 (Figure 4 – Communication start-up) the EVSE should wait for 9V and the EV for the 5% PWM. In some cases the EVSEs and EVs do not behave according to DIN and start the SLAC as soon as a cable-plug-in (PP-resistance) has been detected. Solution:

1. Unplug the EV and EVSE from the PLC-Tracer. 2. Press Initialize SLAC and directly after that Start EV&EVSE. Wait for the V2G Interpreter to be fully

initialized. 3. Plug the EVSE to the right side of the PLC-Tracer. The EVSE should initiate the SLAC immediately. 4. Wait for the first messages to be displayed in the V2G Interpreter (CM_SLAC_PARM.CNF and 5. Following). To be positively sure you should wait for the process to finish. (The last message should be

CM_SET_KEY.CNF.) 6. The EV can be connected and should start automatically with the SLAC process. 7. The session should start now.
