The Team That Makes Charging Systems Work
Clemios fills the gap between protocol foundations and field-ready charging behaviour. When stack vendors or internal teams own the core platform, Clemios takes responsibility for the integration, validation, and delivery work needed to ship reliably under real deployment constraints.
Stack Vendors
Provide protocol foundations and platform components.
Clemios
Closes the delivery gap across hardware, backends, validation, and production timelines.
What Every Engagement Delivers
Every engagement includes protocol integration, firmware delivery, a dedicated team, and conformance validation.
Protocol Integration
OCPP 2.0.1 charger-to-backend integration. OCTT-based conformance preparation included.
Explore protocol scope →Production Firmware
Bare-metal and RTOS controllers shipped with field-update capability, safety compliance, and deterministic timing from first release.
Explore embedded delivery →Dedicated Team
Engineers assigned to one project. German-managed, CET-aligned, full IP transfer. Not rotated across accounts.
Explore team delivery →Conformance Validation
OCTT runs, regression suites, and CI-gated checks catch failures before field deployment. Shipped as part of every delivery.
Explore validation services →Engineering in Action
Selected examples from real EV charging and embedded-system deployments
Charging Protocol Integration for a German Charger OEM
A DC fast charger programme required OCPP 2.0.1 integration across multiple firmware variants and backend systems. Clemios supported protocol integration and delivery alignment without extending the production timeline.
OCPP 2.0.1 integration kept on schedule with conformance preparation aligned
Automated Validation for Safety-Critical Firmware
Safety-critical firmware verification could not scale through manual testing alone. Clemios supported automated validation workflows for repeatable release confidence.
500+ test cases automated for CI-gated regression
Industrial Communication Under Load
An industrial communication issue caused intermittent data loss under load. Clemios supported root-cause analysis and deterministic protocol behaviour under deployment conditions.
Zero data loss after deployment
Delivery Accelerator
FlexCharge.OCPP: Reusable Base. Faster Delivery.
Clemios uses FlexCharge.OCPP as a reusable engineering base for OCPP 2.0.1 integration, backend connectivity patterns, and validation workflows so effort stays focused on project-specific delivery risk.
- Reusable OCPP integration and validation building blocks
- Reduces duplicate engineering work across programmes
- Applied only where it shortens delivery risk
- Stays subordinate to client architecture and ownership
Delivery Model
How Clemios Delivers
How European engineering teams work with Clemios from day one.
Germany-First Communication
Strategic partnership development based in Germany. Client communication and project reporting follow German management standards. Onsite engineering support available for critical project phases.
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. 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.
Engagement Models
Choose the Delivery Structure
Match scope, pace, and operating horizon to the right engagement model.
Pilot
Defined-Scope Engineering
Single integration or validation milestone. 1-2 engineers, 4-12 weeks. Fixed deliverable: one protocol layer integrated, one conformance report delivered, or one firmware module production-ready. Exit criteria agreed upfront.
Programme
Sustained OEM Delivery
Multi-protocol integration or continuous firmware delivery. 3-6 engineers, 6+ months. Covers OCPP, backend APIs, and regression testing in parallel. Monthly engineering reports, shared backlog, sprint-level coordination with your team.
Partnership
Long-Term Collaboration
Dedicated team embedded in your engineering org. 6+ engineers, 12+ months. Custom governance: joint architecture reviews, shared CI pipelines, dedicated technical lead. Scales with your charger programme across hardware variants.
EV Charging Engineering FAQ
Five questions that matter before a first technical conversation.
Clemios is an eMobility software engineering partner that integrates EV charging protocols into production firmware and delivers conformance-ready systems through dedicated engineering teams.
Yes. Clemios integrates into existing architectures rather than replacing them. Existing charger firmware, backend platforms, and vendor stacks can stay in place where that best supports delivery.
All intellectual property created during an engagement belongs to the client. Clemios works with NDA and IP-assignment structures that support clear ownership of delivery outputs.
Clemios supports interoperability validation, automated testing, and OCTT-based conformance preparation so delivery teams can move from protocol integration to deployment-ready behaviour.
Engineers are allocated by protocol area, not rotated between projects. Knowledge stays inside the team through documented engineering artifacts, shared repositories, and overlap periods during any transition.
