The Application Presentation

How our application is working ?

- The ChargeAngels Application is running over the cloud. The communication between the backend and chargers is the Rest Webservice OCPP1.6J or 2.0.1J.
- It is also possible to collect other kind of asserts by integrating proprietary webservices from vendor such as photovoltaics or Energy Management Systems.
- The OCPP Open Charge Point Protocol (ISO15118-2): Defines the way to charge from the EV to the CSO (Charging Station Operator).
- The OSCP Open Smart Charging Protocol: Connection from CSO to DSO (Distribution System Operator) i.e. Smart City and Grid providers.

How about Security ?

- We have 3 ways to identify Users: By RFID Badge Authentication, Using a mobile phone, by exchanging Certificates between Cars, Chargers and eMSPs.
- The OCPP2.0.1 is currently in production on few charger brands, incorporates security messages to transmit ISO15118-2 related X.509 certificates.
- Plug&Charge via ISO15118-2 thus enables secure authentication and authorization of a charging process by plugin in the charging cable: Plug&Charge.
