Technical documentation for NeLeSo charging products

NeLeSo OCPP Gateway and NeLeSo Charging Platform are the two commercial production products. These pages cover architecture, product boundaries, APIs and integration while keeping Developer Kit and Sandbox explicitly separate from production runtimes.

Platform One shared OCPP protocol foundation

Connections, state and commands follow versioned contracts. The Gateway addresses existing backends; the Platform operates charging infrastructure. Statements apply to the exact offered release.

Architecture

Shared OCPP services form the technical foundation.

The foundation handles station connections, state and commands. Routing scope and product-specific user interfaces, APIs and operating models follow each product boundary.

Single source of truth

One documentation source, version-specific API references.

NeLeSo documents centrally

Architecture, product boundaries, concepts and API status are documented here publicly in German and English.

Local Swagger for approved services

Installed product releases may expose their exact OpenAPI specification locally. A demo domain is not a public API contract.

OpenAPI follows the product code

Versioned OpenAPI specifications connect the central API documentation with the local runtime reference.
