PCS & BMS Software

Battery pack with BMS circuit board

Feature development for power conversion systems and battery management systems, running on industrial PCs at site.

PCS / BMS emulators let your team test without hardware, while remote monitoring and EMS dashboards give a live view of state of charge, power flow and fault status across the fleet.

eMSP

User-centric eMobility service platforms: access to your charging network, transparent pricing and billing, and intuitive payments.

We integrate cleanly with existing infrastructure and design for the market changes still to come.

04

V2X

Vehicle-to-Grid, Vehicle-to-Home and Vehicle-to-Building applications, from smart charging to energy management.

We address privacy, infrastructure and legislative challenges with secure communication, infrastructure-compatible software and compliance across markets.

EV Fleet Solutions

Fleet charging management that connects utilities with fleet operators, from cloud SaaS platforms to utility demand response programs.

Dynamic load management, multi-tenancy and maintenance workflows across many EVSE brands, over Modbus, ChargePoint API and OCPP.

EMS & BESS Integration

Years of EMS projects, including virtual power plants and battery storage, give us a unique view where renewable energy meets eMobility.

Our technology-agnostic approach links EVSE, EMS, BESS and renewable assets, so stored energy powers smart charging and boosts resilience at peak demand.

07

Demand Response Integration

V2H and V2G will play a crucial role in future DR programs. We build integrations that align EV charging with grid demands.

With IEEE 2030.5 and OpenADR expertise, your EVSE users can join incentive programs while strengthening grid stability.

08

Smart Charging Solutions

Cloud systems that coordinate vehicles, stations and operators for optimal energy use: power sharing, load balancing and power boost, without infrastructure changes.

Charging schedules, consumption control and automated billing, ready for renewable sources.

09

EV Custom Software Development

Generic software rarely solves eMobility’s unique challenges. We analyse your ideas and turn them into a strategic blueprint, starting with a workshop that previews our collaboration.

From OCPP to advanced V2X, every solution is robust, scalable and aligned with your infrastructure and goals.

EV Driver Apps

Client-facing apps built through consultative workshops and agile delivery: station finder, charger types, live status, route planning, reservations and community insights.

Everything drivers need, from charging speed to network features, in an intuitive UI.
