ENGINEERING ASSET
FlexCharge.OCPP
Our OCPP delivery accelerator. A reusable, modular engineering asset that accelerates OCPP integration for EV charging projects.
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.
What Is FlexCharge.OCPP?
FlexCharge.OCPP is an internal engineering asset developed by Clemios. It provides a modular, production-grade OCPP implementation that our engineers use to accelerate protocol integration in EV charging projects.
The architecture abstracts transport, security, and hardware layers, allowing Clemios engineers to focus on client-specific integration requirements rather than rebuilding protocol foundations for each project.
FlexCharge.OCPP is not a product for sale. It is an internal engineering asset that our teams use to deliver OCPP integration faster and with higher quality.
Architecture
| Layer | Scope |
|---|---|
| 1. Protocol Core | Message routing, state handling, profile support |
| 2. Communication Layer | Transport and session handling, message encoding and decoding |
| 3. Security and Certificates | TLS session handling, certificate lifecycle |
| 4. Hardware Abstraction | Drivers, I/O adapters, vendor-specific isolation |
| 5. Diagnostics and Logging | Structured logging and metrics, fault reporting |
| 6. Lifecycle and Update Hooks | Boot and shutdown handling, update management |
Engineering Capabilities
- Modular, production-grade architecture
- Supports OCPP 2.0.1 (OCPP 2.1 in development)
- Abstracts transport and security layers
- Vendor-agnostic hardware abstraction
FlexCharge.OCPP reduces integration risk and ramp-up time for new OCPP projects. Instead of building protocol infrastructure from scratch, Clemios engineers integrate pre-built modules into client-specific architectures. This means faster delivery and fewer integration defects.
Frequently Asked Questions
No. It is an internal engineering asset. Clemios uses it to deliver OCPP integration projects. It is not available as a standalone product, SaaS, or licensable stack.
OCPP 2.0.1 is actively implemented. OCPP 2.1 is in development.
The hardware abstraction layer is vendor-agnostic by design, supporting multiple chip vendors and I/O configurations.
It provides pre-built protocol, transport, security, and diagnostic modules that Clemios engineers integrate into client-specific architectures, reducing ramp-up time.
FlexCharge.OCPP is not independently certified. Clemios is actively testing with OCTT and aligns with OCA standards.
