IP Ownership
All intellectual property created during an engagement belongs to the client. Engineers sign NDAs and IP assignment agreements as part of employment contracts. No shared-IP clauses.
Team Continuity
Dedicated engineering teams with multiple engineers assigned per EV charging protocol area. Academy-trained engineers join projects through structured onboarding. If an assigned engineer leaves, handover is immediate.
Secure Development
GitLab-hosted repositories with mandatory code review gates. Encrypted storage. Development practices aligned with EU AI Act requirements. GDPR-compliant data handling for EU engagements.
Standards Participation
Participant in the OCA working group developing OCPP 2.1 certification requirements. Actively testing with OCTT. Plugfest participation in preparation for real-hardware interoperability validation.
Engineering in Action
Selected examples from real deployments across eMobility, healthcare, and industrial systems
OCPP Integration for a German Charger OEM
A DC fast charger required OCPP 2.0.1 integration across two firmware variants and three backend systems. The constraint: achieving conformance without delaying an existing production timeline.
OCPP 2.0.1 conformance delivered within production schedule
Embedded Test Automation for a Healthcare Device Manufacturer
Safety-critical MCU firmware required verification across CAN bus, temperature compensation, and EEPROM integrity. Manual testing could not scale with release frequency. A CI-gated automated pipeline replaced the bottleneck.
500+ test cases automated, CI-gated regression replacing manual verification
Communication Protocol Fix for an Industrial Systems Integrator
Intermittent data loss in a multi-device Modbus RTU network. The root cause was timing drift under load. Resolution required deterministic task scheduling and time synchronisation across all nodes.
Zero data loss after deployment
Engineering Asset
FlexCharge.OCPP (Delivery Accelerator)
A modular OCPP implementation that eliminates rebuilding protocol foundations for each project. Clemios engineers start from a production-tested base covering transport, security, and hardware abstraction layers, then focus on client-specific integration requirements.
- Reusable across projects
- OCPP 2.0.1 actively implemented
- OCPP 2.1 in development
- Designed for integration, not resale

EV Charging Engineering FAQ
Common questions about how Clemios operates, delivers, and handles EV charging engineering engagements.
Engineering teams are based in Bangangte, Cameroon. Strategic partnership development and client communication operate from Germany. All project management follows German engineering standards with structured documentation and full traceability.
All intellectual property created during an engagement belongs to the client. Engineers sign NDAs and IP assignment agreements as part of employment contracts. No shared-IP or retained-license clauses.
The Clemios website is hosted on EU-based infrastructure (Hostinger, Lithuania). Client project data residency is defined per engagement contract. GDPR processor agreements are available for EU engagements. Development infrastructure uses encrypted repositories and access-controlled environments.
Clemios operates Monday to Friday, 08:00 to 17:30 GMT+1, with Saturday availability from 08:00 to 12:00. GMT+1 matches Central European Time during winter. During European summer (CEST), there is a one-hour offset. Cameroon does not observe daylight saving. Core business hours still overlap fully with the European working day.
Clemios integrates with existing vendor stacks when the project requires it. FlexCharge.OCPP is used when building OCPP implementations from scratch or when the existing stack cannot meet EV charging integration requirements. The choice depends on project constraints, not on a preference for one approach. OEMs and CPOs retain full control over stack decisions.
Timelines depend on hardware complexity, number of OCPP profiles, and backend integration requirements. Initial scoping and architecture review typically take one to two weeks. Integration scope is defined during that phase. Clemios does not publish standard timelines because each EV charger platform has different constraints.
Multiple engineers are assigned per protocol area. All project knowledge is documented through structured handover procedures. Academy-trained engineers join projects through structured onboarding, creating bench depth. If an assigned engineer leaves, handover to a trained replacement is immediate.
Clemios actively tests with OCTT (the OCA Compliance Testing Tool). Clemios participates in the OCA working group developing OCPP 2.1 certification requirements. Plugfest participation is in preparation for real-hardware interoperability validation. Certification is granted by the Open Charge Alliance, not by Clemios.
