Stack vendors build stacks.
Clemios makes EV charging systems work in real deployments.
Clemios complements protocol stack vendors without competing. The focus: making their technology work in real deployments.
Delivered at production scale
Engineering in Action
Selected examples from real deployments
OCPP Integration for a German Charger OEM
A DC fast charger required OCPP 2.0.1 integration across two firmware variants and three backend systems. The challenge: achieving conformance without delaying an existing production timeline.
Significantly faster commissioning vs. previous generation
Embedded Test Automation for a Healthcare Device Manufacturer
Safety-critical MCU firmware required verification across CAN bus, temperature compensation, and EEPROM integrity. Manual testing could not scale with release frequency. A CI-gated automated pipeline replaced the bottleneck.
~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. The root cause was timing drift under load. Resolution required deterministic task scheduling and time synchronisation across all nodes.
Zero data loss after deployment
Engineering Asset
FlexCharge.OCPP (Delivery Accelerator)
A modular, production-grade OCPP implementation that accelerates project delivery. Six architectural layers, from transport to business logic, purpose-built for real charger hardware and backend systems.
- Reusable across projects
- OCPP 2.0.1 actively implemented
- OCPP 2.1 in development
- Designed for integration, not resale

Engineers Trained Through the Academy Programme
Two cohorts. 100% employment rate. 0% voluntary dropout. 90% retention in remote engineering roles. The growing programme spans 5 specialisations, including eMobility, embedded systems, AI-assisted development, and cybersecurity.
In academic partnership with Universite des Montagnes, Cameroon.
Engineering Academy Programme →Engineering Engagement
Engagement Models
Three engagement structures sized by deployment scope. Commercial terms are defined during scoping.
Pilot
Early deployments and pilots
Best for
Pilot rollouts, early production deployments, defined-scope programmes
Delivery Scope
- OCPP 2.0.1 and 2.1 integration iOCPP IntegrationThe open protocol standard for communication between charging stations and backend systems. Both current (2.0.1) and next-gen (2.1) versions are integrated.
- Monitoring, diagnostics, and remote operational support iOperational SupportOngoing care for the deployment: performance monitoring, diagnostics, hands-on issue triage, and remote guidance when problems arise.
- AI modules available as add-ons iAI Add-onsOptional intelligent modules for predictive maintenance, load management, and data analytics. Activated as needed.
Support
Email support, 48 h response
Programme
Scaled deployments with dedicated engineering capacity
Best for
OEM programmes, sustained rollouts, multi-site deployments
Delivery Scope
- Pilot scope extended with deeper integration and lifecycle support iExtended IntegrationDeeper customisation of the OCPP integration for specific charger hardware, backend systems, and business logic.
- Operational support for complex deployment scenarios
- Dedicated engineering capacity assigned for programme delivery iEngineering CapacityDedicated engineering time for change requests, adaptations, and field issues. Capacity defined during scoping.
Support
Email + phone support, 32 h response
Partnership
Large-scale infrastructure with individual SLA and governance
Best for
Large-scale deployments, high availability requirements, bespoke integration and governance
Delivery Scope
- Dedicated account and delivery ownership iDedicated AccountA single named point of contact for all technical and commercial matters, from onboarding through ongoing operations.
- Custom integration scope and change management
- Individual SLA and support processes iIndividual SLAA custom service-level agreement with committed response times, resolution targets, and escalation paths defined per programme.
- Additional modules activated as required by the programme
Support
Individual SLA + dedicated account manager
All engagement models include conformance testing. Commercial terms, SLAs, and delivery scope are confirmed during scoping. Structured for the European market.
