Who We Deliver For

EV Charging Engineering for Three Buyer Profiles

Clemios supports EV charging teams when the challenge is no longer only selecting a stack, but making the complete system work under real deployment constraints.

Bring charger firmware and OCPP integration into production

For charger OEMs preparing new or updated hardware for release, Clemios supports OCPP 2.1 integration, embedded firmware adaptation, multi-CSMS validation, and release-focused engineering execution.

Resolve charger-to-backend interoperability gaps

For operators and backend teams, Clemios helps identify protocol, transaction-flow, and integration issues across real CSMS environments without forcing a full replacement.

Add delivery capacity where integration becomes the bottleneck

For stack vendors and hardware partners, Clemios adds engineering execution across firmware, backend fit, validation, and production-readiness work while staying subordinate to the client architecture.

Choose the engagement shape around the delivery risk

Pilot

Scoped integration, validation, or firmware work for early delivery decisions.

Programme

Sustained engineering capacity for production releases and recurring integration work.

Partnership

Long-term delivery structure for multi-release EV charging programmes.

Not a Stack Vendor. Not a Generic Engineering Agency.

Clemios works in the delivery gap between protocol foundations, charger hardware, backend systems, and field-ready behaviour. When a stack exists but the system still has to ship, Clemios brings the engineering execution needed to integrate, validate, and stabilize EV charging systems under real deployment constraints.

Pure stack vendor Clemios
Provides protocol foundations and reusable stack components. Integrates firmware, backends, validation workflows, and release constraints around the client architecture.
Optimizes for reusable scope. Optimizes for project-specific delivery risk, real hardware, and production readiness.
May define how the stack should behave. Helps prove how the complete charging system behaves before release.

What Every Engagement Delivers

Protocol Specialization (OCPP 2.1)

OCPP 2.1 implemented and ready for certification. Handling charger-to-backend flows, backend variance, and real CSMS integration.

Hardware Abstraction (HAL) & Firmware

Bridging the gap between protocol and hardware. Modular HAL mapping, metrological integration for EU/German standards, and embedded firmware for production-ready behavior.

Validation & Conformance Readiness

Moving beyond lab simulations. Testing against real hardware, OCTT-based conformance preparation, and bridging the gap between certification and safe field operation.

Dedicated Engineering Capacity

Structured engineering teams for sustained EV charging programmes, with Germany-managed coordination, documented delivery, and client-owned IP.

Engineering in Action

Selected anonymized examples show how Clemios handles EV charging and embedded delivery problems without exposing client-confidential details.

OCPP Integration Across Charger Variants

A charger programme needed OCPP 2.1 integration across multiple firmware variants and backend environments. Clemios supported protocol integration, backend alignment, and conformance-preparation work while keeping delivery focused on release readiness.

OCPP 2.1 integration and validation work stayed aligned with the production plan.

Automated Firmware Validation

A firmware team needed repeatable regression confidence instead of manual release checks. Clemios supported automated validation workflows and CI-gated test execution for embedded charging software.

Validation became repeatable before release, with defects surfaced earlier in the engineering cycle.

Deployment-Condition Debugging

An intermittent communication issue appeared under load and could not be reproduced reliably in a mock environment. Clemios supported root-cause analysis with protocol, firmware, and deployment-condition context.

The integration issue was isolated, corrected, and verified under production-representative conditions.

Client names remain protected by NDA. The engineering problems and delivery patterns are real; public details are anonymized to protect client IP and commercial context.

FlexCharge.OCPP: Reusable Base. Faster Delivery.

FlexCharge.OCPP is Clemios' reusable engineering accelerator for OCPP 2.1 (Production Standard) integration, backend connectivity patterns, and validation workflows. It helps reduce duplicate engineering work while keeping the final system aligned with the client's architecture, ownership model, and deployment constraints.

  • Reusable OCPP 2.1 integration and validation building blocks
  • Backend connectivity patterns informed by real CSMS integration work
  • Conformance-preparation workflows that support release readiness
  • Applied only where it reduces delivery risk
  • Client architecture and client-owned IP remain primary

Germany-Managed Delivery for European EV Charging Programmes

Germany-Managed Communication

Commercial coordination, reporting, and client communication are managed through Germany-based delivery structures.

European Collaboration Rhythm

Delivery routines are aligned with European engineering teams, decision cycles, and working-time overlap.

Client-Owned IP

All engagement-specific delivery outputs and IP rights stay with the client.

Secure Engineering Workflows

Work is managed through structured repositories, controlled access, documented handover, code review practices, and GDPR-aware handling where relevant.

Continuity Across Longer Programmes

Team-based knowledge allocation, documentation, and handover routines reduce single-person dependency across longer engagements.

EV Charging Engineering FAQ

What does Clemios do?

Clemios is an eMobility software engineering partner. The team specializes in EV charging protocols (OCPP 2.1), Hardware Abstraction Layers (HAL), and metrological integration for chargers. We help OEMs move from protocol scope to production-ready charging behaviour.

Is Clemios a stack vendor?

No. Clemios is service-led. FlexCharge.OCPP is a reusable engineering asset (including an OCPP 2.1 core) that accelerates delivery and bridges the gap between certification and production hardware. It is not a standalone SaaS product.

Can Clemios work with an existing stack?

Yes. Clemios works around your existing architecture. We handle HAL mapping, metrological integration, validation, and protocol logic to ensure your existing hardware or backend stack meets production standards without needing a full rewrite.

Which protocol versions are supported?

OCPP 2.1 is implemented and ready for certification. Clemios is actively testing with OCTT for conformance preparation.

Does Clemios support conformance preparation?

Yes. Clemios supports interoperability validation, automated testing, real hardware checks, and OCTT-based conformance preparation and interoperability validation. Formal certification is not claimed where it has not been achieved.

Who owns the IP created during an engagement?

The client owns the engagement-specific IP and delivery outputs. Clemios works with NDA and IP-assignment structures that keep ownership clear.

How does Clemios maintain continuity across longer programmes?

Continuity is supported through team-based knowledge allocation, documented engineering decisions, structured handover, and Germany-managed communication routines.
