Public product documentation

2026 status

Platform architecture

Shared OCPP services, clearly separated product boundaries.

Versioned contracts describe protocol behaviour, connections, state and commands. The OCPP Gateway addresses external targets, observation and migration; the Charging Platform operates and integrates charging infrastructure.

Architecture principle Protocol behaviour remains consistent; routing scope follows the product boundary.

The OCPP Gateway and Charging Platform are commercial production products. Developer Kit and Sandbox remain technically and commercially separate non-production paths.

System flow

OCPP contracts connect charge points to two production products.

Shared contracts do not automatically mean identical releases. Every capability statement requires evidence for the exact offered Gateway or Platform release.

Shared contract

Four areas are consistent across all products.

01

Protocol behaviour

OCPP messages, state transitions, errors and timeouts follow the same tested rules.

02

Product boundaries

External targets, read-only observation and controlled migration belong to the Gateway. CPMS and operating processes belong to the Charging Platform.

03

Event and data model

Stations, sessions, meter values and commands retain stable identities across product layers.

04

Compatibility

Shared compatibility tests protect the OCPP and routing contracts across products.

Product profiles

Two production products, two non-production paths.

Developer Kit and Sandbox are not cheaper Platform plans and contain no approved production runtime.

Product boundaries

Differences sit above the OCPP protocol layer.
