Expand description

OCPP Charging Station Management System microservice.

/<prefix>/<identity> (OCPP listeners, plain and/or TLS): OCPP-J 1.6, 2.0.1 and 2.1 over WebSocket.
/api/v1/... (API listener): station registry, search, commands.

Modules§

api: Internal HTTP API used by the rest of the platform.
auth: Charging-station authentication: HTTP Basic (OCPP Security Profiles 1 and 2).
calls: Sending a validated CALL to a connected station and mapping the outcome.
config: Configuration from environment variables.
db: PostgreSQL access. Queries are plain SQL checked by the integration tests (no compile-time database connection required).
error: HTTP API error type.
hub: Registry of the station connections held by this node.
ocpp: OCPP-J endpoint: handshake, per-connection session and the handlers of each OCPP version. Version modules are fully separate; they only share the version-neutral persistence helpers of StationCtx.
reservation: Reservations (OCPP 1.6 §3.11, §5.1, §5.13; OCPP 2.x H01–H04).
server: Accept loop for the OCPP listeners (plain and TLS).
smart: Smart charging (OCPP 1.6 §3.13 / Smart Charging profile, OCPP 2.x block K).
state
tariff: Tariff and cost (OCPP 2.0.1 block I, OCPP 2.1 block I).
tls: TLS for the OCPP endpoint (OCPP 2.0.1/2.1 Part 2 §A00, OCPP 1.6 security whitepaper).
tz: IANA time zones from the system zoneinfo database (TZif files, RFC 8536), including the POSIX TZ footer rule used for instants after the last listed transition. Needed because OCPP 2.1 tariff conditions are expressed in station local time, following daylight saving time (I12.FR.37).
