5.4.4Charging Stations/Charge Point/Configuration
When a charging controller is in the factory default configuration, the charging point is not configured. The charging controller is configured for the first time under “Create configuration”. The name of the menu changes to “Configuration” later in the process. You can copy the configuration of a different charging point at the top of the page. This makes it easier to create identical or almost identical charging points. Figure 5-12 shows the configuration page view.

Settings for the charging point name and location are required. The name serves to uniquely identify the charging point and configuration. The charging controller you assign to the charging point is identified by a UID. If you change the settings, click the “Save” button to save your changes.
The remaining structure of the configuration is divided into different areas. The available areas are: Charging Connection, Energy, Monitoring, Release Charging, and ISO 15118.
The settings for “Charging Connection” cover the area between the charging controller and the vehicle. | |
Type of connection from the charging point. –Socket Outlet: A charging socket is mounted at the charging point. The connection is established by a mobile charging cable. –Connector: A permanently connected charging cable with charging connector is attached to the charging point. | |
Standard | Standard of the charging socket to be connected. –IEC 62196 This setting is only available in conjunction with the “Socket Outlet” connection type. |
Socket Outlet Type | In this field, you select the charging socket type. This is abbreviated in accordance with the actuator selection in the item designation. –4-pos. charging socket, Marquardt type actuator –4-pos. charging socket, Küster type actuator –3-pos. charging socket, Hella type actuator This setting is only available in conjunction with the “Socket Outlet” connection type. |
You select the moment when the actuator should lock the charging socket. –On EV connected – disconnected: As soon as a vehicle is connected to the charging socket, it is locked. Disconnection on the vehicle side is required first to unlock the charging socket. –Remote control: Locking is not controlled automatically, instead it must be controlled externally. This can be done via OCPP (corresponding configuration required), Modbus, or the REST API, for example. This setting is only available in conjunction with the “Socket Outlet” connection type. | |
Plug Rejection | Charging connectors with cables with low current carrying capacity will be rejected by the charging controller. In this case, charging does not take place and the charging point switches to the error state. –Reject 13 A –Reject 20 A & 13 A This setting is only available in conjunction with the “Socket Outlet” connection type. |
Status D Vehicle Rejection | The charging controller rejects or accepts vehicles that require additional ventilation. –Reject –Accept |
Charging current settings and settings for the energy measuring device are made in the “Energy” area. The settings are not linked; charging current settings are also valid without an energy measuring device. | |
Energy | Charge Currents | |
Charge Current Minimum | The configured minimum set current of the charging point in amps. |
Charge Current Maximum | The configured maximum set current of the charging point in amps. The set current is always within the limits of the minimum and maximum charging current. |
Fallback charging current, in amps. This charging current setting is automatically set when the fallback time has elapsed. | |
Fallback time in seconds. In the event that the connection to the relevant front module is lost, the charging controller waits a certain amount of time before switching to the fallback charging current. During an active connection, the elapsing timer is repeatedly increased to the fallback time and therefore the fallback charging current is not applied. | |
Energy | Energy measuring device settings | |
Energy Measuring Device Type | You select the energy measuring device type here. –Phoenix Contact EEM-350 EEM-350-D-MCB, 2905849 –Phoenix Contact EEM-EM357/EEM-DM357 EEM-EM357, 2908588 EEM-DM357, 252817 EEM-DM357-70, 1219095 –Phoenix Contact EEM-EM357-EE EEM-EM357-EE, 1311985 –Phoenix Contact EEM-157-EE EEM-EM157-EE, 1311993 –Phoenix Contact EEM-AM157-70 EEM-AM157-EE, 1219090 –Carlo Gavazzi EM24 –Carlo Gavazzi EM340 –Carlo Gavazzi EM111 –Inepro Metering PRO380 –Iskra WM3M4(C) |
You define the phase rotation at the measuring device connection here. This configuration is not required, but does improve load management behavior and makes it possible to limit out-of-balance loads. This setting can only be set in conjunction with a configured energy measuring device type. | |
Calibration Law | |
Charge Point Abbreviation for Screen | The specified abbreviation is shown on the display. |
Selection of the charging point: | Selection of the charging point: Via RFID reader: –Via screen: –The settings are only relevant if the calibration function is used. |
Monitoring | Protection The safety equipment detects errors at the charging point and switches the charging point to the error state. Safety equipment is configured in the “Monitoring” settings. Connect the safety equipment in accordance with “Connecting and wiring the hardware” on page 51. | |
Load contactor monitoring is used to detect a non-opening contactor. Specify one of the digital inputs for this. | |
Select the type of the auxiliary contact for monitoring. N/C contact: When the contactor is stuck, the contact is open and no voltage is applied. N/O contact: When the contactor is stuck, the contact is closed and 12 V are applied. | |
You can enable or disable DC residual current monitoring via a check box. The residual current sensor must be connected in accordance with “Operation without a DC residual current sensor – with a type B residual current device” on page 59. | |
Monitoring | Charge Current Monitoring Charging current monitoring is only possible if a measuring device is configured. The charging current can then be checked for an impermissible overrange or out-of-balance load of the defined set current. | |
Over Current Detection | Select the type of overcurrent monitoring. –EV/ZE Ready: Derating is performed in defined stages as per the EV/ZE Ready standard. –Overcurrent shutdown: Shutdown in the event of an overcurrent in a time period of 100 s (>110% of the set current) or 10 s (>120% of the set current) If overcurrent monitoring has been triggered, charging is started again after one minute. If overcurrent occurs again, an error status is set for the charging point. |
Out-of-balance suppression to a maximum of 20 A can be enabled and disabled via the check box. Out-of-balance suppression is implemented for each charging point. | |
Monitoring | Derating Derating is performed in the event that a measured temperature is exceeded. The derating function can be configured as linear derating or as activation. The connection and method of operation is illustrated in “Connecting temperature sensors” on page 69. | |
Sensor Type | Select the sensor type for temperature monitoring and derating here. –Pt 1000: A Pt 1000 sensor is connected to the charging controller. Then you can configure the start temperature, stop temperature, start current, and stop current. –PTC: A PTC chain is connected to the charging controller. Then you can configure a terminating resistor. |
Start Temperature (when Pt 1000 is selected) | Temperature in °C at which derating begins. To ensure that derating is applied, the start temperature must be less than the end temperature. The start current must be greater than the end current. |
Stop Temperature (when Pt 1000 is selected) | Temperature in °C at which derating stops the charging process. |
The charging release determines when a vehicle is authorized to charge. Without a charging release, the vehicle stays in status B. | |
Via Dashboard: The release is only issued via the web page and must be issued manually. This is only possible on the dashboard and the status page of the charging controller. By Local Whitelist: The whitelist, which is checked when an RFID card or EVCC ID is presented, is stored locally on the charging controller. The RFID cards or EVCC IDs must be managed under “Whitelist”. Via Remote Control: The release is issued and withdrawn via an external system. For example, the release is issued via the REST API or Event Actions. Permanent Charging Release: The charging release is issued on a permanent basis and is not withdrawn. The charging release cannot be withdrawn via the web page. If the charging release is to be withdrawn, the charging point can be unlocked or locked. The release is issued and withdrawn via the connected OCPP backend. Additional release via the web page is not possible.
Via Modbus: The release is issued and withdrawn via the Modbus registers. Additional release via the web page is not possible. | |
The RFID reader used at the charging point is specified via the RFID reader terminal point. All the charging points available in the network are therefore listed here. For example: “Chargepoint 2”. This means the RFID reader at “Chargepoint 2”. | |
Type of RFID Reader | You can select the type of the RFID reader. –ELATEC TWN4 –DUALI MDE 950-4 XCP –Netronix UW-XEU1 –CHARX RFID/NFC |
RFID Timeout | Time after which a charging release via RFID is discarded if no vehicle is connected. The time is specified in seconds. |
OCPP ConnectorID | The default value is “-1”. You must specify an ID here; this ID must be unique in the charging park. You must specify the ID starting from 1. The ID represents the ID in the OCPP backend.
|
ISO 15118 You must make special settings to activate ISO 15118 communication on the Variable „Product Area 3“ ist nicht definiert and -3150 modules. | |
ISO 15118 communication is activated via the High Level Communication (HLC) setting. –Required: Only vehicles with HLC can be charged at the charging point. –Optional: Vehicles with HLC as well as vehicles without HLC can be charged. –Disabled: There is no HLC, i.e., no communication in accordance with ISO 15118, at the charging point. | |
EVSE ID | The assigned EVSE ID for the charging point is entered here. The format is “CountryCode”+ “Operator ID” + “E”+ “ChargingStation ID”, e.g., DE123E4567 |
The vehicle can be informed via HLC that charging is free. This option is selected via the check box. | |
Payment Options | Payment can either be made by means of vehicle identification or conventional external payment. If certificates cannot be loaded via the web page, customers can only select the following option: Allow External Payment. |
TLS Policy | Certificates cannot be loaded via the web page at present. The TLS policy is for display purposes only. |
