What is Plug & Charge?
By using Plug & Charge, it is possible to authorize an electric vehicle simply by plugging it into a charging station, without the need for additional steps such as scanning a QR code, entering payment information or holding a charging card in front of the station. The electric vehicle and the charging station automatically communicate with each other to exchange the necessary information and start the charging process.
Are you interested in using Plug & Charge via be.ENERGISED?
| Please note that PnC via be.ENERGISED is currently only possible for charging stations from the manufacturer Alpitronic (HYC300 and HYC150). |
Plug & Charge is a separate product for charging station owners (CPOs) that can be purchased for your be.ENERGISED instance. Therefore, if you are interested, please contact your sales partner at ChargePoint Austria. Once you have received the information that Plug & Charge has been activated for you, you will need to take the following steps in be.ENERGISED.
Settings in be.ENERGISED: step-by-step
1) Activation of PnC in the rights management
To be able to make settings regarding Plug & Charge, you must activate the corresponding right for the respective user groups. You can access the rights management in be.ENERGISED under User management/Groups/Group list. Then click on the "Rights" button and then on the "Infrastructure management" tab. There you will find the right "Enable 'Plug and Charge' in the cp datasheet". Activate the right to enable all tabs for Plug & Charge in the charging station data sheet.
2) Activation of PnC in the charging station data sheet (per charging station)
In the next step, go to the charging station data sheet of the charging station for which you want to activate Plug & Charge. We need to inform you again that this is currently only possible for charging stations of the manufacturer Alpitronic (HYC300 and HYC150). The following settings must be made individually for each charging station.
You can access the charging station data sheet in be.ENERGISED under Infrastructure/ Charging stations/ Station list.
Select the desired charging station from the station list. Click on the data sheet icon to get to the station data sheet.
There, go to "Edit" and then to "Plug and Charge". Set the slider there to YES. Then confirm the setting with "Save".
This setting enables the "PnC certificates" and "PnC logs" tabs in the charging station data sheet. In the PnC logs, you can see log entries for the authorizations that took place via Plug and Charge. In the "PnC certificates" tab, you can see the root certificates.
|
Even if the corresponding certificates are already present at the charging station, this must be activated for "Plug and Charge" (see steps above). Otherwise, the authorization process will not work. |
In addition, you must ensure that Plug and Charge is also enabled directly (is not related to the activation of Plug and Charge in the charging station data sheet) at the charging station (PncEnabled = true) as well as the OCPP PnC message format is set to "HTB16". You can configure this in be.ENERGISED via the charging station data sheet in the "Settings" tab. If you do not find any entries here, click on "Load parameters from charging station". Then you can search for the value "ISO15118PncEnabled" and "OcppPncMessageFormat" for charging stations of the manufacturer Alpitronic and edit it. Please note that the OCPP settings and their name depend on the manufacturer. It may be necessary to restart the charging station after this configuration.
|
You can also perform this configuration using the Bulk operations function in be.ENERGISED. To do this, go to the "Infrastructure" tab, select Bulk operations/ New Bulk Operation and then select the "Set configuration values on stations" option. After filtering on the appropriate charging stations, you need to enter the text "OcppPncMessageFormat" in the "Key" field and the text "HTB16" in the "Value" field. Then add another entry, enter the text "ISO15118PncEnabled" and the value "true". After that, you can finish the process. |
3) EVSE Leaf certificate
As general information in advance: An EVSE Leaf certificate is a charging station certificate. With the help of this certificate, the charging station authenticates itself to the vehicle. During a TLS handshake, the charging station establishes a TLS connection to the vehicle. The charging station authenticates itself to the vehicle by sending its charging station certificate and the CPO sub-CA certificates. This certificate chain was derived from a V2G root CA. The associated private key of a charging point certificate is stored in the charging station.
In the be.ENERGISED backend, the EVSE Leaf certificates do not appear in the "PnC certificates" tab. In many cases (in the case for Alpitronic chargers always), the signature check of the EVSE Leaf certificate takes place automatically when the charging station is activated for PnC in the charging station data sheet. Provided this process worked, you can see the following OCPP message in the "PnC Logs" tab: "Certificate Signed" - "Station Accepted Certificate".
If this process is not started automatically, the signing check in the charging station data sheet can also be triggered manually. To do this, go to the "Trigger message sending" item in the charging station data sheet under "Station management". In the window that opens, select the "Sign EVSE Leaf Certificate (ISO15118)" option in the "Message" item. For the "Connector", select "Charging station". Your selection is confirmed by clicking on "Trigger message!".
After that, please check if you find the above message in the PnC logs.
4) Installation and maintenance of root certificates
For a charging station to be Plug and Charge capable, it must have the corresponding V2G root certificates. In addition, MO (Mobile Operator) root certificates may be required for eMSPs (E-Mobility Service Providers) that maintain their own certificates.
These root certificates are displayed in the charging station data sheet under "PnC certificates".
To check which certificates are already installed on the charging station, you can go here to "Retrieve current information from the charging station". Normally, the V2G root certificate already exists.
If certain certificates are not installed, it is possible to upload them manually. This can be done by you, or for a fee via ChargePoint Austria. The certificates can also be requested via ChargePoint Austria. Therefore, contact our be.ENERGISED support if needed.
Click on the "Add certificate" button and upload the root certificate. This will then appear in the list with the certificate type and serial number.
| Please note that the current Plug and Charge implementation for charging station owners does not provide regular updates of the root certificates stored in the HUBJECT RCP. If new root certificates are introduced, e.g. by eMSPs, you as charging station owner must install the certificates on all charging stations that use Plug and Charge. When new root certificates are introduced, we will notify you. |
5) Passing on POI data to roaming partners
To ensure that the information that your charging station offers Plug and Charge is also passed on to roaming partners and roaming networks, you must set the "PnC" item in the "Roaming" tab of the charging station data sheet to YES. We ask you to perform this step only for charging stations for which you have already fully activated Plug and Charge.
