Building blocks
We advise, build and test e-mobility software. OCPP Broker, OCPP Server and CPMS modules accelerate projects without forcing you into a fixed product model: usable individually, with source code, without lock-in.
Core building blocks
Broker, backend and operations modules cover the core of many charging platforms. We combine them with consulting, custom code and testing into the solution your venture needs.
NeLeSo OCPP Broker
Decoupling between charge point and backend: the broker keeps connections and state, routes messages to target systems and enables backend changes during live operation – with comparison mode and rollback per charge point.
Explore the OCPP Broker
NeLeSo OCPP Server
Production OCPP backend for your own platforms and manufacturer projects. With simulators, test access, a developer portal and open APIs – so your team can integrate and extend.
Explore the OCPP Server
NeLeSo CPMS Toolkit
Operator portal, tariffs, OCPI roaming, billing and further modules for white-label solutions. You take only what your operation needs – and receive the source code as the foundation of your own solution.
Explore the CPMS ToolkitAs an appliance
OCPP server, load management and operations portal also run as a ready-made appliance right at your site – virtually on your hypervisor or as an industrial box in the control cabinet.
Complementary building blocks
Around consulting and delivery we use tools that make project work faster and safer – from simulation and acceptance testing to diagnostics, billing and vehicle integration.
Simulated charge points and e-mobility providers for development, acceptance and load testing: reproducible scenarios instead of waiting for field hardware.
250+ field-proven test cases from our test lab – for authentication, backend communication, load management and firmware. Field issues become reproducible scenarios.
Control directly on site, air-gap-capable: keeps running without a permanent cloud connection and bridges WAN outages with a local message queue.
Logs, events and meter values become understandable cause chains: your support sees what happened and what to do – instead of digging through raw data.
Billing that stands up to audits: SEPA payment runs, XRechnung and ZUGFeRD for business customers, calibration-law-compliant meter values with OCMF signature.
Vehicle data inside your platform: state of charge, range and charging history from the vehicle complement the infrastructure view – for fleets and services.
Approach
In projects the building blocks typically deliver the majority of the solution. Consulting, development and testing turn them into your reliable system.
Operating models & pricing
Identical feature set in all models, source code included. Our managed-cloud model combines the data sovereignty of on-premises with the operational comfort of SaaS: the stack runs in your cloud subscription – deployed, updated and operated by us.
SaaS
Operated in our cloud: updates, operations and 24/7 monitoring by the team that built the building blocks. Onboarding in days, not months.
€5.90 per charge point / monthManaged cloud · proven with DepotCharge
We deploy dev and prod environments in your Azure or AWS tenant and deliver signed updates, monitoring and operations support (8×5). Cloud resources run in your subscription – full data and cost sovereignty.
Setup from €4,900 + €490/month operations + €1.90 per charge point / monthSelf-managed
A licence for your data centre or your own cloud, operated by your team: full control, integration with existing systems – with updates and support from us, source code included.
from €18,000 per year incl. updates & supportEdge / appliance
For environments without a permanent cloud connection: the building blocks as a preconfigured appliance – from the LTE entry box to the AI appliance.

A look inside
The building blocks speak the standards of your market – from OCPP via OCPI to German calibration law. And we show you how they work together: here, the broker between charging park and backends.
