Target picture, architecture review, build-or-buy, migration strategy and regulation (AFIR, calibration law, ISO 15118).
Consulting · CPO/CPMS platform · Edge · since 2011
Charging infrastructure that just runs.
We advise, implement and deliver turnkey platforms for operating charging infrastructure – since 2011, with source code and without lock-in.
We build charging-infrastructure software for companies including:
BMW · Volkswagen · DEKRA · Webasto · Allianz · Audi Denkwerkstatt · WALL-E.works · DepotChargeThree building blocks
Consulting. Platform. Edge.
Focus instead of a full catalogue: we chart the path with you – and deliver the building blocks to build and run your own backend.

Predictable start at a fixed price
Assessment Workshop: clarity in one day.
Switch your backend, expand or run it yourself? One focused working day remotely via Microsoft Teams – architecture, regulation and roadmap – for a fixed price of €4,990 plus VAT. Includes 90 days of full access to a demo instance with all building blocks.
- Architecture review of backend, charge points and interfaces
- Regulatory check: AFIR, German calibration law, ISO 15118
- Prioritised migration or expansion roadmap
- An honest recommendation – even if it is "keep what you have"
- 90 days of full access to a demo instance with all building blocks
Consulting
The decision comes first. Then the code.
Consulting for e-mobility and charging with a focus on infrastructure and backends: we join strategy, architecture and delivery – from the first question into continuous operations.
Design & architecture
System design for charging infrastructure: protocols, interfaces, load management – validated in a proof of concept.
Delivery & operations
Development, testing in our own lab and migration without downtime – with continuous evolution in production.
Platform
The building blocks for your CPO and CPMS backend.
Not an off-the-shelf product, but a platform of proven modules: OCPP, CPMS and billing – with source code, open APIs and no lock-in.
NeLeSo OCPP Broker
One broker. Any backend. Zero downtime.
Decoupling layer between charge point and backend: multi-backend routing and live migration without a big bang.
Explore the OCPP BrokerNeLeSo OCPP Server
The OCPP backend you build on.
OCPP 1.6 and 2.0.1 in production, 2.1-ready – with simulators, developer portal and open APIs.
Explore the OCPP ServerNeLeSo CPMS Toolkit
Modules for operator portal, roaming and billing.
White-label building blocks for your own CPMS – individually or together, with source code.

Where the cloud is not enough: plug in instead of hosting.
OCPP server, load management and monitoring as an appliance in the control cabinet. Offline-first means the site keeps charging even when the internet or cloud fails.
NeLeSo Edge · industrial appliance
Why NeLeSo
Not SaaS lock-in. Not slideware consulting. Not greenfield from scratch.
Our building blocks ship with source code and open APIs. We consult with software we run in the field – and in the Assessment Workshop we tell you honestly whether in-house, platform or keeping the status quo is the path that holds.
Case Studies
Named projects. Building blocks in production.
WALL-E, DepotCharge, Natur & City Camping Ellwangen – and DEKRA in overview.
Multi-tenant CPMS platform for large fleet customers
OCPP Broker and Server for banks, premium OEMs and logistics companies – up to 8,000 charge points per customer.
Read the case study →Billing and high-power DC without heavy IT integration
Broker and mini CPMS – DC chargers up to 1,000 kW routed to existing backends.
Read the case study →Campsite load management
Eight AC chargers, PV, commercial kitchen and sub-circuits – steered by Edge offline-first.
Read the case study →Example from practice
Backend switches without a big bang.
Consulting and platform work together: the broker keeps charge points connected while target systems change step by step – with fallback and parallel operation.
NeLeSo test lab
Test lab since 2014
Field issues, made reproducible in the lab.
Since 2014 we have operated test environments with vehicles, wallboxes and OCPP backends. We turn field issues into reproducible scenarios – against real hardware.
Protocol depth
We have spoken OCPP since 2011.
Our systems see what charge points really send in the field every day – and turn it into stable sessions, clean meter values and traceable diagnostics.
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.
