"Stack vendors build stacks. We make EV charging systems work in real deployments."
Clemios SARL is an engineering services company headquartered in Bangangté, Cameroon, with European business development in Germany. The core focus: eMobility software, OCPP 2.0.1 protocol engineering, embedded firmware, and QA for European charge-point operators and hardware OEMs. Protocol work means navigating real integration constraints, not just implementing a spec. Clemios has been a member of the Open Charge Alliance (OCA) since January 2026. The team has delivered 20+ projects across 4 industries, with 49 trained engineers and a dedicated OCPP group operating under German engineering standards from a Cameroon delivery centre.
They (Stack Vendors)
- Build and license protocol stacks
- Sell standardised software components
- Product-oriented
We (Clemios)
- Integrate protocols into real hardware
- Adapt solutions to your constraints
- Engineering execution-oriented
- Validate interoperability and support long-term operation
We complement protocol stack vendors. We do not compete with them. We make their technology work in your deployment.

Engineering in Action
OCPP Integration for a German Charger OEM
Integrated OCPP 2.0.1 into a DC fast charger. Two firmware variants, three backend systems, one conformance target. Commissioning time dropped significantly.
Significantly faster commissioning vs. previous generation
Embedded Test Automation for a Healthcare Device Manufacturer
Manual verification of safety-critical MCU firmware was the bottleneck. We replaced it with a CI-gated automated pipeline covering CAN bus, temperature compensation, and EEPROM integrity.
~85% reduction in manual test effort (estimated)
Communication Protocol Fix for an Industrial Systems Integrator
Intermittent data loss in a multi-device Modbus RTU network. Root cause: timing drift under load. Fix: deterministic task scheduling and time synchronisation across all nodes.
Zero data loss after deployment
