Technical expertise for eMobility and embedded systems

Clemios delivers embedded and eMobility engineering for EV charging software and connected devices in Germany and the European Union. We build firmware and embedded software for chargers, controllers, and gateways, and we support protocol and backend integrations for interoperability.

Our focus is production readiness. We work with requirements, traceability, unit tests, static analysis, and structured validation. This supports reliable deployment and long term maintainability in real world environments.

How we deliver production ready engineering

  • Requirements and acceptance criteria with traceability

  • Implementation with coding standards and code review

  • Verification with unit tests and static analysis

  • Validation strategy and regression stability aligned with your environment

What this expertise covers

  • Embedded software for EV chargers and gateways
  • EV charging protocol engineering and interoperabilityQA, traceability, and regression stability for embedded systems
  • Integration with charging platforms and backend APIs
  •  

Where we apply this expertise​

We build and validate software for EV charging stations, charger controllers, and gateways. We focus on device connectivity, diagnostics, secure and maintainable firmware, and integration with charging platforms and interoperability workflows. We support OCPP where required and expand protocol coverage based on standards adoption and customer needs.

  • EV charging stations, charger controllers, and gateways
  • Device connectivity, diagnostics, and secure firmware
  • Platform integrations and interoperability workflows

Our EV charging engineering stack covers requirements management, embedded development, QA, protocol integration, and hardware debugging across the full lifecycle.
