OCPP
Open Charge Point Protocol: how chargers talk to the platform.
Voltvik supports OCPP 1.6J and 2.0.1, including security profiles, smart charging and ISO 15118 certificate handling. The live demo on this site runs a real OCPP 1.6J central system: chargers that an admin has registered connect to wss://<host>/ocpp/<id> with OCPP Security Profile 1 (Basic Auth over TLS) and appear in the console.
wss://<host>/ocpp/<chargePointId> Sec-WebSocket-Protocol: ocpp1.6
