Get EV Charging Systems Into Production
Clemios helps charger OEMs and EV infrastructure teams move from protocol scope to production-ready charging behaviour with OCPP 2.0.1 integration, embedded firmware, backend connectivity, real hardware validation, and conformance-preparation workflows.
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 2.0.1 integration, embedded firmware adaptation, multi-CSMS validation, and release-focused engineering execution.

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

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.
Request a Technical Scoping CallNot 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.

What Every Engagement Delivers
Protocol Integration and Backend Connectivity
OCPP 2.0.1 implementation, charger-to-backend message flows, backend variance handling, and integration work across real CSMS environments.
Embedded Charging Firmware
Firmware adaptation, controller integration, target-hardware constraints, and embedded software changes required to make charging behaviour work in the field.
QA, Test, and Conformance Preparation
Automated testing, requirements traceability, CI/CD quality gates, real hardware validation, and OCTT-based conformance preparation and interoperability validation.
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 2.0.1 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 2.0.1 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 2.0.1 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 2.0.1 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.
Engagement Models
Choose the model that matches the scope, urgency, and operating horizon of the EV charging programme.

EV Charging Engineering FAQ
What does Clemios do?
Clemios is an eMobility software engineering partner for EV charging systems. The team supports OCPP 2.0.1 integration, embedded charging firmware, backend connectivity, validation workflows, and production-readiness work for charger OEMs and related EV infrastructure teams.
Is Clemios a stack vendor?
No. Clemios is service-led and stack-agnostic. FlexCharge.OCPP is a reusable engineering accelerator used where it reduces delivery risk; it is not positioned as a boxed offering that replaces the client's architecture.
Can Clemios work with an existing firmware, hardware, or backend stack?
Yes. Clemios integrates into existing architectures when that is the right delivery path. Existing charger firmware, backend systems, stack components, and hardware decisions can remain in place while Clemios supports the integration and validation work around them.
How does Clemios handle OCPP 2.0.1 and OCPP 2.1?
OCPP 2.0.1 is the current production baseline for new OCPP engineering work. OCPP 2.1 support is in development. Clemios engineers systems so the path toward OCPP 2.1 is a controlled evolution rather than a rewrite, but OCPP 2.1 is not presented as the current production baseline.
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.
