Engineering for EV charging and energy platforms
We help eMobility and energy companies build, connect and improve the software behind their operations.

What we do
Software for EV charging and energy systems
We help companies develop and improve the software behind EV charging infrastructure, energy management and connected systems.
EV charging platforms
We develop and extend charging platforms, from charger management and transactions to billing and roaming.
Energy management
We build software for monitoring, controlling and optimising batteries, solar systems and energy consumption.
System integrations
We connect chargers, energy devices, payment providers and business systems through reliable APIs and protocols.
Platform development & support
We improve existing platforms, develop new features and help teams keep critical systems running.

Engineering across the stack
From charging sessions and roaming to battery control and energy optimisation, we work on the technology that keeps connected infrastructure running.
Charging platforms
CSMS development, charger connectivity, charging transactions, tariff management, billing workflows and scalable backend services.
Integrations
CPO/eMSP roaming, smart charging partners, payment terminals, third-party APIs and business system integrations.
Energy optimisation
EMS development, battery and PV integration, energy forecasting, electricity price-based scheduling and grid import/export optimisation.
Smart charging
Dynamic load management, charging session control, priority-based power allocation and handling site power constraints.
Protocols & data
OCPP, OCPI, MQTT, Modbus, real-time telemetry and reliable data exchange between devices and software platforms.
Why Columbix

Production ownership
We take clear ownership of the systems we work on. You always know who is responsible when something needs fixing.
Engineering first
We use AI tools where they speed up the work. Architecture, code review and verification stay with engineers.
End-to-end delivery
Analysis, architecture, development, testing, deployment and production support from one team.
Long-term partnerships
The same engineers stay with your platform from one module to the next, so what they learn about it stays with your team.
