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.

Our services
  • 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.

  1. Charging platforms

    CSMS development, charger connectivity, charging transactions, tariff management, billing workflows and scalable backend services.

  2. Integrations

    CPO/eMSP roaming, smart charging partners, payment terminals, third-party APIs and business system integrations.

  3. Energy optimisation

    EMS development, battery and PV integration, energy forecasting, electricity price-based scheduling and grid import/export optimisation.

  4. Smart charging

    Dynamic load management, charging session control, priority-based power allocation and handling site power constraints.

  5. Protocols & data

    OCPP, OCPI, MQTT, Modbus, real-time telemetry and reliable data exchange between devices and software platforms.

Why Columbix

About us
Columbix engineers working together at a shared table
  • 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.
