eMobility Engineering for Production-Ready EV Charging Systems
Protocol integration, embedded firmware, real-hardware validation, and conformance preparation. Clemios engineers the software that makes EV charging systems work under real deployment constraints for Charger OEMs, CPOs, and backend providers.
Engineering Integration, Not Protocol Stack Sales
Clemios integrates OCPP into real charger hardware, validates against real backends, and supports production deployments.
Charger OEMs
Firmware, OCPP integration, hardware abstraction, and conformance preparation for AC and DC charging hardware manufacturers. Validated on real hardware, tested against real backends.
CPOs and Backend Providers
Backend connectivity, smart charging features, and multi-vendor interoperability for charge point operators running diverse charger fleets.
Tier-1 Suppliers and System Integrators
OCPP protocol engineering, validation workflows, and integration support for companies entering EV charging or adding charging to existing infrastructure products.

Interoperability testing against real backends. Conformance preparation with OCTT. CI/CD quality gates, MISRA C enforcement, and Ceedling TDD for embedded firmware.
Learn more →Accelerated by FlexCharge.OCPP
FlexCharge.OCPP is a modular, production-grade OCPP implementation with six architectural layers. Each layer is purpose-built for real charger hardware and backend systems. It serves as a reusable engineering accelerator across Clemios eMobility projects.
Proven components adapt to specific hardware and backend requirements. The result: faster integration, fewer protocol surprises during field deployment, and conformance-preparation workflows built into the engineering baseline from the start.
- 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.

Clemios is not a protocol stack vendor.
No software components for sale.
Clemios integrates OCPP into real charger hardware, validates it against real backends, prepares for conformance evaluation, and supports it in real deployments. Stack vendors build stacks. Clemios makes EV charging systems work.
The difference matters past the evaluation phase, when protocol code must run on actual hardware, pass interoperability tests, and connect to a CSMS in production. That is where Clemios operates.
How Clemios Complements Stack Vendors →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. Clemios does not manufacture charging stations. The work covers the software that runs on them.
The engineering baseline is OCPP 2.0.1, deployed on real charger hardware, tested against real CSMS backends, and supported in production. OCPP 2.1 is in development. Clemios does not build new systems on OCPP 1.6.
Clemios handles 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. The software runs on charging stations built by OEMs. Clemios complements hardware manufacturers, not competes with them.
Clemios is actively testing with OCTT (Open Charge Compliance Testing tool from the OCA). Conformance preparation includes structured test coverage against OCPP 2.0.1 functional profiles, regression testing across firmware updates, and documentation of test results for OEM review. Clemios prepares systems for conformance evaluation but does not issue certifications.
