Consulting · CPO/CPMS platform · Cloud to Edge · since 2011
Charging infrastructure that just runs.
We advise, implement and deliver turnkey platforms for operating charging infrastructure – since 2011, with open interfaces and clearly agreed source-code rights.
We build charging-infrastructure software for companies including:
BMW · Volkswagen · DEKRA · Webasto · Allianz · Audi Denkwerkstatt · WALL-E.works · DepotChargeTwo pillars
Consulting. Platform.
We chart the path with you and deliver the software to build and run your own backend. You choose the operating model independently: cloud, on-premises or directly at the edge.

Which path fits?
Go from your need to the right NeLeSo offering.
Four starting points, two production products and one clearly bounded evaluation path.
Existing backend Connect charge points under control or migrate a backend. NeLeSo OCPP Gateway · commercial production product → CPO/CPMS operations Operate charging infrastructure with portals, processes and integrations. NeLeSo Charging Platform · Starter, Professional or Enterprise → Public evaluation Explore prepared workflows with synthetic data. NeLeSo Sandbox · non-production and reset regularly → Local development Review planned local developer tooling. NeLeSo Developer Kit · publication review still pending →
OCPP Server, CoreCPMS and CPMS modules are technical building blocks inside the products – not additional public product lines.

- Prepared customer scenario and 90 days of private Enterprise test access
- One joint follow-up session during the access period
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 controlled migration with a fallback plan – with continuous evolution in production.
Platform
Two commercial production products.
The NeLeSo Charging Platform operates charging infrastructure under Starter, Professional and Enterprise plans. The NeLeSo OCPP Gateway connects, observes and migrates existing backends. Both production products are commercial; the Sandbox remains clearly separate.
NeLeSo OCPP Gateway
Connect external OCPP targets under explicit control.
A technical standalone package comprising Broker and Server: one primary backend plus an optional read-only observer per Charge Point ID, with CoreCPMS as the default.
NeLeSo Charging Platform
Operate charging infrastructure in production.
One commercial Platform with Starter, Professional and Enterprise plans – delivered as SaaS, on-premises or an appliance depending on the project.
The public Sandbox is synthetic, resettable and reset regularly. It accepts no customer data, production credentials or external charge points and carries no production SLA. Production station and transaction traffic is not enabled. The Developer Kit remains unpublished pending rights and security review. OCPP Server, CoreCPMS and CPMS modules are technical building blocks inside the products, not additional public product lines.
Cloud · On-premises · Edge
The same software, operated where it fits your system.
The Charging Platform is delivered as SaaS, on-premises or an appliance depending on the project. The OCPP Gateway is intended as a managed or self-managed installation for an existing backend. The quotation defines the selected deployment mode and its prerequisites.
- SaaS or managed cloud for centrally accountable operations
- On-premises in your VM, container or data-centre environment
- Local core at the Edge, designed for isolated networks where required
- External roaming, payment and partner services still require connectivity
Why NeLeSo
Not SaaS lock-in. Not slideware consulting. Not greenfield from scratch.
Our building blocks have open APIs. Source-code access and usage rights are committed in the specific quotation. 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 Gateway 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.
Insights

OCPP Security
OCPP security: what the first CPMS CVEs mean for operators
The new CPMS CVEs expose four recurring OCPP risks: missing station authentication, unrestricted authentication attempts, session hijacking and publicly known station IDs. What operators should test now – and how we secure the NeLeSo Charging Platform.
