OCPP 1.6 & 2.0.1 in production
Both versions run in production – including smart charging, firmware updates and security profiles. OCPP 2.1 is already prepared.
NeLeSo Charging Platform · OCPP Server
The OCPP backend you build on.
The production protocol building block of the NeLeSo Charging Platform for developing, testing and operating your charging infrastructure – ready on day one instead of 12 to 18 months of in-house development. With test access, simulators, central documentation and open APIs for your team – in the cloud, on-premises or directly at the Edge.
The OCPP Server is one of our software building blocks: proven in the field – and the foundation for custom solutions we develop with you and test against real hardware.
Who is it for?
One backend, two perspectives.
For wallbox manufacturers
The backend for your own product.
Development, testing and certification preparation against a production OCPP backend – plus field diagnostics once your devices are out at customer sites.
For platform teams
The OCPP protocol layer instead of building your own.
Open APIs, webhooks and clean data models: you build your product, the server handles protocol, sessions and meter values.
Cloud · On-premises · Edge
The OCPP protocol services run where you need them.
The same software base runs as SaaS, in your data centre or on a Linux edge system directly at the charging site. A cloudless standalone deployment means the local OCPP services have no permanent dependency on a NeLeSo cloud.
- Containerised on a VM, bare metal or suitable edge hardware
- Local OCPP connections and smart-charging core without a cloud requirement
- Air-gap-capable deployment for isolated networks
- Roaming, payment, remote support and partner services need their respective connection
Protocol depth
For us, protocols are not a roadmap slide.
Whatever appears on our standards list runs in production – or is clearly marked as prepared.
Illustrative capture of an OCPP session: the charge point boots (BootNotification), becomes available, starts a charging transaction with meter values – and load management adjusts the power in real time.
ISO 15118-20 Plug & Charge
Certificate-based charging without a card or app – with a native Hubject connection for contract certificates and certificate handling in the backend.
OCPI 2.2 / 2.3 for roaming
Locations, tariffs, sessions and CDRs for roaming partners – on both the CPO and EMP side, including a test environment for partner onboarding.
Developer experience
Built for teams that integrate instead of picking up the phone.
Everything your team needs for the integration is documented, simulatable and reachable via API – from the first request to production operations.
Central documentation, local Swagger reference
Cross-product guidance on neleso.com; where already available, the installed version exposes its exact OpenAPI specification and Swagger UI locally.
Open API documentationCharger simulator
Virtual OCPP 1.6 and 2.0.1 charge points for development and CI: boots, sessions and fault patterns – reproducible by click or API.
OCPI/EMP simulator
Test roaming scenarios before the partner is connected: locations, sessions and CDRs from simulated EMP systems.
REST APIs & webhooks
Clean data models for charge points, sessions and meter values – events arrive in your system via webhook, right where you need them.
AI/MCP integration
Controlled tooling for AI-assisted operations: query status, pull diagnostics and review configuration – with clearly scoped access to operational data.
Operations
24/7 monitoring and proven production operations with operators in the field – for us, scaling is routine, not a project.
NeLeSo Test Lab · since 2014
Proof through testing
250+ field-proven test cases before your product ships.
Since 2014 we have been running a test lab with wallboxes, vehicles and metering points. It has produced more than 250 practical test cases that manufacturers use to validate firmware and configuration – before a fault surfaces at a customer site.
- Firmware and configuration validation against 250+ test cases
- Certification preparation for OCPP 1.6 and 2.0.1
- Field-fault analysis turned into reproducible scenarios
Support tools for manufacturers and installers are available at wallbox-support.com.
FAQ
Frequently asked questions about the OCPP Server.
Can I run the OCPP Server on-premises?
Yes. The same software base runs as SaaS, on-premises in your infrastructure or on suitable edge hardware at the site. The local OCPP services can operate without a permanent connection to a NeLeSo cloud. External partner services still require their intended connectivity.
How do I test against the OCPP Server?
The charger simulator creates virtual OCPP 1.6 and OCPP 2.0.1 charge points for development and CI, while the OCPI/EMP simulator covers roaming scenarios. For real hardware, request test access and connect your wallbox straight to a dedicated WebSocket endpoint.
Does the OCPP Server support German calibration law (Eichrecht)?
Yes. The server processes and stores OCMF-signed meter values, so charging sessions can be billed in compliance with German calibration law and verified by end customers through transparency software.
What is the difference between the OCPP Server and the OCPP Gateway?
The OCPP Server is the protocol building block of the NeLeSo Charging Platform: it manages charge points, sessions and meter values and exposes APIs for applications. The OCPP Gateway is the separate commercial product for external backends, observation and migration. Gateway and Server can be combined deliberately in Platform and migration projects.
