eMobility Engineering for EV Charging Systems That Ship on Time
From charger firmware to backend integration, from OCPP implementation to interoperability testing. Clemios engineers the software that makes EV charging infrastructure work in production.
Clemios is an eMobility software engineering partner delivering EV charging, OCPP, embedded, and test-ready systems through dedicated engineering teams for German and EU companies.

Mehr erfahren →Why Clemios for eMobility?
- OCA member since January 2026. Same standards body as Trialog and EcoG.
- OCPP 2.0.1 actively implemented across real charger hardware.
- Dedicated engineering team for OCPP and FlexCharge development.
- FlexCharge.OCPP: reusable 6-layer engineering asset. Not a product.
- Germany-first delivery. Managed from Germany, engineered in Cameroon.
- AI-enhanced engineering. We use prompt engineering, RAG, and MCP to accelerate code analysis, protocol research, and documentation workflows.
Clemios is not a protocol stack vendor. We do not sell software components.
We integrate OCPP into real charger hardware, validate it against real backends, and support it in real deployments. Stack vendors build stacks. We make EV charging systems work.
The difference matters when you are past the evaluation phase and need protocol code running on actual hardware, passing interoperability tests, and connecting to your CSMS in production. That is where Clemios operates.
Learn How We Complement Stack Vendors →Built on FlexCharge.OCPP
Every eMobility project we deliver starts with FlexCharge.OCPP. It is a modular, production-grade OCPP implementation with six architectural layers. Each layer is purpose-built for real charger hardware and backend systems.
Because the architecture is reusable, we do not build from scratch for each client. We adapt proven components to specific hardware and backend requirements. The result: faster integration, fewer protocol surprises during field deployment, and a lower risk profile for the overall project.
- Protocol Core. Message routing, state handling, profile support across OCPP functional blocks.
- Communication. WebSocket transport, JSON encoding and decoding, retry logic, session management.
- Security. TLS session setup, certificate lifecycle management, security profile enforcement.
- Hardware Abstraction. Chip-specific drivers, vendor isolation, capability APIs for 8 MCU families.
- Diagnostics. Structured logging, metrics collection, fault reporting. Built for field reproducibility.
- Lifecycle. Boot sequencing, graceful shutdown, firmware update management, controlled recovery.
Industries We Serve
Charger OEMs
Firmware, OCPP integration, and hardware abstraction for AC and DC charging hardware manufacturers. We work on your hardware, not in simulation.
CPOs and Backend Providers
Backend connectivity, smart charging features, and multi-vendor interoperability for charge point operators running diverse charger fleets.
Automotive and Energy
Protocol engineering and testing for automotive Tier-1 suppliers, energy utilities, and fleet operators entering the EV charging market.
Frequently Asked Questions
The software and firmware that powers EV charging infrastructure: charger controllers, communication protocols like OCPP, backend integration, and smart charging features. Clemios specialises in the engineering services that make these systems work in production. We do not manufacture charging stations. We build and validate the software that runs on them.
Our engineering baseline is OCPP 2.0.1. We deploy it on real charger hardware, test it against real CSMS backends, and support it in production. OCPP 2.1 is in active development. We do not build new systems on OCPP 1.6.
We handle the full path. On the charger side: OCPP protocol implementation, message routing, device model management. Between charger and backend: secure TLS communication, WebSocket transport, retry logic. On the backend side: API connectivity and multi-vendor interoperability testing. FlexCharge.OCPP provides production-tested components so integration starts from proven code, not from scratch.
No. Clemios is an engineering services company, not a hardware manufacturer. We build the software that runs on charging stations built by OEMs. We complement hardware manufacturers, we do not compete with them.
