How to set up a secured charging station connection: OCPP 1.6 J version 

Communication between charging stations and the Charge Point Operator (CPO) is established via the WebSocket protocol at:

• ws://ws.evc-net.com — for standard connections
• ws://ws-private.evc-net.com — for charge points connected via our private VPN SIM card

Note: By default, OCPP websockets are not encrypted and provide no way for authenticating a chargepoint.

To strengthen security and ensure trusted communication, we recommend:

• Upgrading WS to WSS

• Using basic authentication
• Using root certification for verification

Please, note that we highly recommend that you update charge points to at least profile 2.

• Open the charger dashboard at data of http://evc-net.com .
• Set security profile 2/ to “Basic authentication over HTTP/WS” .
• Input the security data as CHARGERBOXID : Base 64 character or Ascii values and save.

• Open the charger dashboard at data of http://evc-net.com.
• Set up the security profile to 3/ “Basic authentication over HTTPS/WWS”.
  
• Input the security data as CHARGERBOXID : Base 64 character or Ascii values and save.

• Open the charger dashboard at data of http://evc-net.com .
• Set security profile to 4/ Client certificate over HTTPS/WWS” .With this case the charge point needs to get a signed certificate authorization from LMS back end but the charger needs to also have a root certificate for verification.
• Input the security data as CHARGERBOXID : Base 64 character or Ascii values and save.

Note: At this moment, using this connection is not recommended, as it can be taken over by simply guessing the communication-id of your charge point.

Use at least “Basic authentication over HTTP/WS” (mandatory), or another secure method which is listed as “recommended”.

This option will no longer be available starting 1 January 2027.

• Open the charger dashboard at data of http://evc-net.com .
• Set the security profile 1/none for no Authentications.

The setup may differ per manufacturer. For further specifications, please refer to the manual of your charge point manufacturer.
