Context
The engagement landscape
Built a pan-European EV charging platform from scratch, serving 100,000+ users across 10+ countries while reducing operating cost per station and delivering ahead of schedule.
Challenge
What needed to change
The initiative started without a team, roadmap, budget, or clear product vision, even though the goal was to unify fragmented charging networks across Europe into a business-critical platform.
Intervention
How EnCoCo responded
EnCoCo built the cross-functional team, aligned stakeholders on product and budget, and designed a Rust-based microservice platform in Azure with harmonized APIs and a modular pricing engine.
Pull quote
“EnCoCo turned a rough idea into a coherent product, team, and platform plan that could scale across fragmented charging networks.”
Story
How the work unfolded
Starting point
At E.ON, EnCoCo started with no team, no roadmap, and no clear product vision. The ambition was to build a scalable communication gateway that could give EV drivers seamless access to Europe's fragmented charging networks.
The early constraints were severe: no developers, no onboarding process, no defined budget, and a technical landscape full of incompatible systems, inconsistent pricing, and slow integrations. EnCoCo stepped in to turn a rough idea into a coherent product and delivery plan.
How EnCoCo responded
EnCoCo assembled a new development team from scratch, introduced onboarding frameworks, and aligned stakeholders across countries around a clear product vision and budget structure. Delivery was broken into modular packages so the platform could progress incrementally while still aiming for pan-European scale.
To handle integration complexity, EnCoCo designed a harmonized API ecosystem using OCPI, OCPP, and OSCP and paired it with an adapter-based pricing engine for regional tariffs, customer-specific pricing, and transparent billing. The technical foundation was a Rust-based microservice architecture hosted on Azure for performance, security, and maintainability.
What changed
The result was more than a successful launch. EnCoCo delivered production-critical services under budget, ahead of schedule, and without downtime, while building a platform that already serves more than 100,000 users in over 10 countries and reduces integration and operating cost per charging station by 30%.
