On the first page click/press on the “Settings” button and scroll down to the “Essential parameters” window where you see the settings. Press the “Change parameters” button and enter the password “param2011” to be able to change settings. Then change settings as needed/required and press the “Confirm” button below to save new settings.

4. DESCRIPTION OF EACH ESSENTIAL PARAMETER the installer can set:

5. Test the 3/1‐phase main fuse protection dynamic charging:
   Connect to WiFi and go to the Metron Charge Control web‐based application. Connect the electric vehicle to the charging station and observe the charging current measurements in the WiFI Charge Control app. under “Advanced info”. Intentionally put the big load to each of the phases (one by one) to surpass the main fuse rated current and observe if the charging current decreased in the way the total main fuse current is not higher than the main fuse rated current. To do that you need to connect the powerful load to each phase (the easiest way is to use regular 2 kW electric heaters – 1,2,3… connected in parallel.

6. Explain to the client that the charging station will automatically reduce or stop the charging in case of main fuse overload. In case of charging interruption because of overload, the blue status LED will blink 4 times (with a pause after 4 blinks) until the load on the main fuse is low enough to resume charging. The main fuse current on the most loaded phase needs to be app. 7A lower than rated fuse current for the charging station will allow charging to start/resume. The status LED can blink 4 times even if the vehicle is not connected. This will inform the user that the charging cannot start until the other powerful house loads are switched off.

7. Explain to the client that in the case of an installed solar/wind/hydro power plant the charging station allows vehicle charging with a higher overall current than the set nominal main fuse value (this function doesn’t work at night of course). This feature is active only in case Solar/wind/hydro power plant phases = House grid connection phases.

WIRELESS

4. Install and set the 3FD‐3 DYNAMIC EV CHARGING UNIT as described on pages 7, 8 and 9 or older 3FD‐2 DYNAMIC EV CHARGING UNIT as described in QUICK INSTALLATION GUIDE rev.4. 3FD‐3 and 3FD‐2 units are compatible, the difference is in max. fuse rating (3FD‐2 up to 250A, 3FD‐3 up to 1000A) and max. number of controlled charging stations (3FD‐2 can control up to 30 stations, 3FD‐3 up 150 stations).

INSTALLATION

INSTALLING the 3FD‐3 DYNAMIC EV CHARGING UNIT for 1 3‐ 3-or phase MAIN FUSE protection WIRELESS DYNAMIC charging of up to 150 wall-mounted and portable charging stations per main fuse

1. Activate wireless FUSE  protection DYNAMIC charging on wall-mounted station(s) as described on Page  3 (smart portable stations have enabled wireless dynamic charging RF receiver by default). You also need to set house phases and solar phases but don’t change the main fuse rating on the wall-mounted station (leave default 35 A or set it back to 35A if it has been changed).
2. Install the 3FD‐3 DYNAMIC EV CHARGING UNIT and supply current measuring transformers (CT) on the house/building main power supply input (in the house main distribution panel) as shown on the 3FD‐3‐1 or/and 3FD‐3‐2 drawings in the attachment.
3. Set the needed parameters via the Metron Dynamic Power Control application. You enter the Dynamic Power Control application the same way as the Charge Control application on stations (see instructions on page 2) except that the default WiFi name (SSID) is in this case “METRON Dynamic 1”. On the first page click/press on the “Settings” button and scroll down to the “Essential parameters” window where you see the settings. Press the “Change parameters” button and enter the password “param2011” to be able to change settings. Then change settings as needed/required and press the “Confirm new parameters” button below to save new settings.
4. DESCRIPTION OF EACH ESSENTIAL PARAMETER the installer can set:
5. 5. In case there are more than 1 WALL MOUNTED AND/OR PORTABLE station(s) to be controlled by the 3FD‐3 DYNAMIC EV CHARGING UNIT set the number of charging stations as described on Page 7. At the same time, you need to set the parameter station ID for each wall-mounted or wireless charging station (see Pages 3 and

6. in the way each charging station has its ID starting from 1. Example: you have 3 charging stations connected to the same main fuse; set the ID on the first one to 1, the second one to 2 and the third one to 3. The station ID is displayed in the WiFi Charge Control app. in the “Advanced info” menu. The DYNAMIC fuse protection charging works also in case you have a MIXED configuration ‐ 1 or more wall-mounted and 1 or more portable stations powered from the same main fuse!
   6. Test the 3/1‐phase wireless main fuse protection dynamic charging: Connect to WiFi and go to the Metron Charge Control application on one of the wirelessly controlled charging stations. Connect the electric vehicle to the charging station and observe the charging current measurements in the WiFI Charge Control app. under “Advanced info”. Intentionally put the big load to each of the phases (one by one) to surpass the main fuse rated current and observe if the charging current decreased in the way the total main fuse current is not higher than the main fuse rated current. To do that you need to connect the powerful loads to each phase (the easiest way is to use regular 2 kW electric heaters – 1,2,3… connected in parallel). Simultaneously you can connect to Metron Dynamic power control application on the 3FD‐3 unit and observe real-time load/currents there also.

6. If there is no signal from the 3FD‐3 unit detected on the charging station side (you can see that information in the WiFi Metron Charge Control application under “Advanced info”) the wall-mounted charging station will stop charging and the front blue status LED will blink 4 times as in case of main fuse overload condition but the portable charging station will continue charging with user selected charging current/power – this function is logical for portable stations because when you charge somewhere else where 3FD‐3 unit is not present its purpose is to charge.
   Communication signal detection on wall-mounted stations can also be observed if LED2 is connected between terminal 20 and GND on the Micro EVSE 3 DYNAMIC WiFi EV charge controller in the charging station (signal present = LED2 on; no signal = LED2 off). Portable stations have SIGNAL LED already installed.

7. Extending the wireless range of  3FD‐3  DYNAMIC  EV  CHARGING  UNIT:  in case the  3FD‐3  and controlled stations are far away from each other (50m+ air distance) or there are thick concrete walls in between the signal may be too weak. But there are 2 ways of extending the wireless range:

   • Install an external 433 MHz antenna on a station(s). Use pliers and cut off the built‐in antenna.  The antenna shall be installed on the outside wall and connected with the attached cable to the Micro EVSE 3 DYNAMIC WiFi EV charge controller. Use pliers and cut off the built‐in antenna. This is the most effective way to extend signal range. Note: It is not possible to install additional antennae on portable stations.
   • Install additional 433 MHz antenna on 3FD‐3 DYNAMIC EV CHARGING UNIT. Use pliers and cut off the built‐in antenna. This antenna also helps extend the range but it’s less effective.

8. Explain to the client that the 3FD‐3 DYNAMIC EV CHARGING UNIT distributes the charging power to all wirelessly controlled charging stations equally. However, the client can still adjust the charging power on each station via a front button or the current setting slider in the WiFi Metron Charge Control application.

9. Explain to the client that in the case of wirelessly controlling only one (1) charging station it will automatically reduce charging power or stop the charging in case of main fuse overload. In case of charging interruption because of overload, the station’s front blue status LED will blink 4 times (with a pause after 4 blinks) until the load on the main fuse is low enough to resume charging. The main fuse current on the most loaded phase needs to be app. 7A lower than rated fuse current for the 3FD‐3 will allow charging to
   start/resume. The blue front status LED can blink 4 times even if the vehicle is not connected. This informs the user in advance that charging cannot start until the other powerful house loads are switched off.

10. Explain to the client that in case of wirelessly controlling two (2) or more charging stations, it will automatically reduce the charging power on all the stations in case of main fuse overload. If that is not enough it will stop charging on one or more charging stations starting with the one with ha highest station ID number. In case of charging interruption because of overload the affected station’s front blue status LED will blink 4 times (with pausa e after 4 blinks) until the load on the main fuse is low enough to resume charging. If the main fuse is too overloaded by other loads it will stop charging on all the stations. After the load on the main fuse is reduced the charging will be resumed starting on the stations with lower station ID numbers (lower station’s ID numbers have priority over the higher station’s ID numbers). The main fuse current on the most loaded phase needs to be app. n x 7A lower (n = number of stations that will be allowed to resume charging) than the rated fuse current for the 3FD‐3 will allow charging to start/resume on the additional n charging stations. The blue front status LED on one or more stations can blink 4 times even if the vehicle(s) is(are) not connected. This informs the user in advance that charging cannot start until the other powerful house loads are switched off.

11. Explain to the client that in case of an installed solar/wind/hydro power plant, the 3FD‐2 DYNAMIC EV CHARGING UNIT allows vehicle charging with higher overall current than the set nominal main fuse value (this function doesn’t work at night of course). This feature is active only in case Solar/wind/hydro power plant phases = House grid connection phases.

12. Explain to the client that in case of using a PORTABLE CHARGING STATION PC03X+ / PC04X+ / PC05X+ on 2 or more different places (e.g. the client has 2 houses), it is possible to install the 3FD‐3 DYNAMIC EV CHARGING UNITs on 2 or more different locations (e.g. 2 houses) with different main fuses and then just move/use the same PORTABLE CHARGING STATION on those different locations and have everywhere safe wireless FUSE protection DYNAMIC charging. The PORTABLE CHARGING STATION connects automatically to the 3FD‐3 DYNAMIC EV CHARGING UNIT at every location.

Management With Micro EVSE 3 DYNAMIC WiFI OCPP charge controller

1. Micro EVSE 3 DYNAMIC WiFi OCPP charge controller supports OCPP 1.6 communication protocol compliant connection of the charging station to any OCPP backend system. OCPP 1.6 communication protocol is used for charging management. Most used OCPP functionalities are the implementation of payment for charging by RFID card/reading QR code, etc or just monitoring the charging energy and changing the charging power. It also allows the operators/users to see station state (car connected, charging, charging complete), charging power, charging current, charging energy, manually activate or stop charging, unlocking the charging connector, resetting the OCPP module and even perform over‐the‐air (OTA) updates of the OCPP firmware if needed. All those OCPP 1.6 functions are supported by Metron Micro EVSE 3 DYNAMIC WiFi OCPP charge controller.
2. All needed settings regarding the OCPP 1.6 connection can be set via the Metron Charge Control application. On the first page click/press on the “Settings” button and scroll down to the “OCPP 1.6 connection parameters” window.
3. DESCRIPTION OF OCPP PARAMETERS The installer can set the:

LOCAL RFID card management

LOCAL RFID cards management with Micro EVSE 3 DYNAMIC WiFI OCPP charge controller

1. Micro EVSE 3 DYNAMIC WiFi OCPP charge controller supports reading of ISO/IEC 1443A compatible MIFARE Classic RFID cards. If there is an OPCC connection established and the user scans/swipes the card the card number is sent to the OCPP backend to check if the card is authorized or not. This is the first way the user can use the card. The second way of using the cards is to make local authorization by ADDING the cards to the local authorized list of cards. This local RFID card list can store up to 100 cards and in case of starting the charging with those locally stored cards, you don’t need an OCPP connection or internet. Besides this, the charging energy per each locally stored card is recorded. To see how much energy was transferred per each stored card you just scan/swipe the card and the kWh number will be displayed in the Charge Control app. Charging energy can also be reset to 0 kWh on each card separately when needed.
