Description: Protocol for commissioning electric vehicle chargers using the professional application RAEDIAN INSTALL

FIRST STEPS

• Download App RAEDIAN INSTALL on Smartphone (available on iOS and Android). This is the recommended app for installers to perform equipment commissioning.

• Activate Bluetooth on Smartphone.

• Register in the App.

HOME SCREEN

• In the screen interface, in first configuration, the different ranges of RAEDIAN chargers appear. Choose the range to which the charger to be started belongs.

• Once the charger has been chosen, various tutorials (Quick guide, manual and installation video) appear which may be useful to the installer. Connecting the charger.

• For the first configuration, it is necessary to have coverage or WiFi connection. For start-ups with no coverage, 2 options are available:

1. To bring a network cable from a router and a repeater for WiFi signal (it can be used to monitor the charger later).
2. Preconfigure the charger in the workshop/headquarter and install it later.

CONNECT CHARGER

• Select the charger to be started (the serial number appears when connecting the Bluetooth) and connect it. To make sure that the serial number is correct, it can be found in several places:

1. Inside the back cover of the charger.
2. On the left loop of the charger.
3. In the instruction manual that comes in the box(advisable not to get rid of it).

• Enter the PIN of the charger that you want to start up. The PIN can be found in different places:

1. Inside the back cover of the charger.
2. In the instruction manual that comes in the box(it is advisable not to get rid of it).

• When entering serial number and PIN, a screen with device and serial number appears. Once verified that it is the correct charger, select the location (automatically by activating the location in Smartphone or manually) and start the configuration.

CONFIGURATION

This is the most important part of the setup.

• First of all, enter the power configuration. This step is important, as it will define the maximum power of the installation and the maximum power at which the vehicle can be charged (it will always be less than the available power). A mistake in this step may cause the protections of the installation to be triggered. The following data must be entered:

1. Home network input: Select whether the installation is single-phase (1 phase) or three-phase (3 phases).
2. Rated current of the mains input circuit breaker/fuse: Select the current of the differential switch of the electrical panel. The load current will always be lower.
3. Grounding system: Select the system that you have in the installation. Usually it is a TN/TT system.
4. Charging current: Select the maximum current at which the electric vehicle will be charged. It will always be less than the nominal input current of the grid.

• Subsequently, enter connectivity. Choose how the charger is to be connected to monitor it during its use.

1. WiFi. Available in all RAEDIAN ranges. A 2.4GHz network is required. Network name + password. Typical for residential or commercial installations with a single charging point.
2. Bluetooth: Available on all RAEDIAN ranges. Once set up, it connects automatically when in the vicinity of the charger. Typical for local monitoring, updates and reporting.
3. Ethernet: Available on NEX and GEMINI ranges. Typical in commercial installations or with more than one recharging point, to daisy-chain chargers.
4. 4G: NEX, GEMINI and NEO ranges with built-in eSIM. Either eSIM embedded in the charger can be used or a physical SIM can be inserted by the customer (as long as it is unlocked). Typical in systems where it is not possible to carry WiFi or Ethernet network.

• The next step is the OCPP profile, if and when it is necessary to monitor, manage consumption, charges and reports through third party platforms. It is therefore an optional step. The default RAEDIAN OCPP 1.6 profile appears, in the drop-down menu the credentials (OCPP profile and password) of the third party application are written. It is necessary that they accept OCPP 1.6 protocol.

• Next, access. Here you define how the interaction between the loader and the person is going to be. Two options.

1. Plug & Play: No credentials required. Most common in single-family homes or some kind of company where anyone can charge.
2. Authorization: With RFID card or through access with the App. In cases in which it is intended that only certain people can charge, such as a public parking or a company.

• The next step is load management. This is an important step as it is going to define how the electric vehicle is going to be charged. There are several options:

1. Charging management by CT kit: usual in residential chargers, where there is only one charger per installation.

Kit CT is the toroidal clamp that is incorporated in the charger box. For three-phase installations, 2 additional clamps (RD-NEO-CT-80A) are required. These clamps read the consumption of the installation and allow the charger to charge with the highest power available on the line, so that an efficient and safe charge is produced.

The QR code on the clamps must be scanned in the App. These clamps are connected to an adapter, which also comes in the box, and which in turn has to be connected by mains cable to the charger to perform the charge balancing.

The clamp must be positioned in such a way that it reads the data correctly. This is simply checked if the current reading gives positive data. If not, it is necessary to connect it in the opposite direction.

In the case of three-phase installations, it is necessary to indicate the installation position for each clamp (L1, L2, L3). In single-phase installations, only one position must be indicated (L1).

If you have a single-phase installation of solar panels, you can add an additional clamp to the inverter output, indicate it in the App and charge only with the surplus solar energy(Solar Only).

2. SC Kit load management: common in residential installations with three-phase solar systems or commercial and industrial installations

SC Kit is an additional bi-directional Smart Meter for DIN rail from RAEDIAN. There are single-phase and three-phase models, with clamps included to read the consumption of the installation.

It is connected via RS485 to the adapter, which comes in the charger box, which in turn is connected via network cable to the charger and is read by the App. The clamps read the consumption of the installation and allow the charger to charge with the highest power available on the line, so that an efficient and safe charge is produced.

It has the option of Solar Only function (charging exclusively with excess solar radiation). As it is a bi-directional meter there is no need to add additional clamps, as it reads incoming and outgoing power.

3. Load management via EMS: common for installers or customers working with third-party applications.

With an external Smart Meter. The charger adapter is connected to the Smart Meter via RS485.

It is necessary to indicate the Smart Meter data for its correct operation: Modbus address, baud rate, parity and stop bits.

4. Fixed charging current: usual in cases with a charger where there is a lot of power available (a company or a ship).

Set the charger to always charge at the same power. Caution must be taken since, if this fixed current is higher than the available one, the electrical protections of the installation will be triggered. This is the default mode, the current is indicated above in the power configuration.

• Then there is RFID management. This is an optional step, common when access to the charger is restricted to certain people, such as a public parking lot, or cases where it is necessary to charge indirectly based on consumption (parking in a neighborhood community, guests in a hotel). To assign RFID cards to the charger, it is very simple. On site, the card is swiped through the charger reader (located at the bottom of the display), a "beep" is heard, it is accepted and the card is paired.

• The last step in the configuration is the firmware update. It is strongly recommended to update the charger firmware during start-up. During the update, which takes a few minutes, do not disconnect the charger.

• Once the charger has been updated, confirm and disconnect. The charger is now ready for use.
