Premium OEMs
For BMW, Volkswagen and Audi Denkwerkstatt we worked on vehicle data, charging processes and test automation – from early pilot fleets to series-production environments.
NeLeSo GmbH · Hohenschäftlarn near Munich
Since 2010 we have built software that has to survive in the field.
NeLeSo is an owner-managed engineering company, not a VC-funded startup: founded in 2010, in e-mobility since 2011, with our own test lab since 2014. Today our systems run in production with operators in the field – supported by the same team that built them.
Information security
NeLeSo is ISO/IEC 27001 certified.
Information security is firmly embedded in our processes and responsibilities. For customers working with sensitive operational, vehicle or infrastructure data, this provides a dependable foundation from the first workshop through ongoing operations.
- Certified information security management system
- Structured handling of risks, access and changes
- Traceable processes for development, testing and operations
History
From engineering projects to consulting & software building blocks.
Four milestones, one direction: software for energy and mobility that has to hold up in continuous operation – not just in the demo.
- 2010 · Founded Started as a software engineering company for energy and mobility – owner-managed from day one.
- 2011 · e-mobility First OEM projects around vehicle data and charging, including for BMW – the entry into the domain that has carried us ever since.
- 2014 · Test lab Built our own test environment with vehicles, wallboxes and measurement equipment – the source of 250+ field-proven test cases to date.
- 2026 · Consulting & building blocks Strategy, concept and implementation with proven software building blocks for OCPP, CPMS and billing – proven in production with operators in the field.

Who we work and have worked for.
Much of this work is confidential – the names and the fields of work are ones we may share.
Testing & insurance
For DEKRA and Allianz we built software for inspection processes and data platforms – where measurements have to be reliable and processes traceable.
Charging infrastructure
For Webasto, WALL-E.works and DepotCharge we build and operate backends, test environments and operations platforms – from the first charge point to the running charging network.
How we work
How you can tell it is us.
Four principles that apply to every project – whether consulting, migration or custom engineering.
- Standards over lock-in: OCPP, OCPI and ISO 15118 instead of proprietary interfaces
- Source code is part of the deliverable – you stay in control, even without us
- Field reality beats slide-deck architecture: decisions follow what happens in the charging network
- A direct line to engineering instead of an account manager
NELESO TEST LAB · HOHENSCHÄFTLARN · SINCE 2014
Test lab since 2014
The heart of it all: real wallboxes, real vehicles, real failures.
Our test lab in Hohenschäftlarn is where software meets field reality: wallboxes from different manufacturers, vehicles, measurement equipment and OCPP backends in one setup. What breaks there no longer breaks in your charging network.
- Wallboxes from various manufacturers and firmware versions in continuous operation
- Field failures are preserved as reproducible test scenarios
- 250+ test cases from twelve years of lab operation
Owner-managed
People who stand behind their decisions.
NeLeSo is run by its managing directors Sebastian Böttger and Dr. Thomas Ganswindt – without investors breathing down our necks and without quarterly logic. For you that means: whoever decides on your architecture also owns it for the long run. You talk to the same people at kickoff, in operations and for the next expansion step.
