Interoperability Failures Are Slowing Down Your Network Growth
As networks scale, Charge Point Operators (CPOs) and eMobility Service Providers (eMSPs) face interoperability challenges across diverse hardware and software. Systems that manage 500 chargers often struggle to support 5,000, causing vendor lock-in, unreliable roaming, and infrastructure overhead.
Intelliarts solves this through expert OCPP 1.6 / OCPP 2.0.1 development. We also use OCPI integration to connect your network with global EV roaming hubs. By implementing smart charging and Plug & Charge certificate management support, we turn fragmented networks into a unified, high-performance ecosystem.
Building Scalable EV Charging Platforms with OCPP/OCPI Development
Multi-vendor interoperability
We apply deep protocol knowledge of OCPP 1.6 and 2.0.1 for stable communication between heterogeneous charging stations and backend systems. By handling vendor-specific variations and protocol edge cases, we minimize failed sessions and ensure predictable charger behavior.
Roaming enablement via OCPI
Our team designs and implements OCPI integrations that allow charging networks to establish reliable roaming partnerships. Our validation approach reduces disputes and keeps session data accurate across platforms.
Scalable backend architecture
Our backend systems can handle high transaction throughput as your charger fleet scales from hundreds to thousands of devices. We optimize everything from message queue to load balancing and high-availability deployment.
Operational efficiency
Automated conformance testing, interoperability simulations, and structured onboarding pipelines reduce certification cycles and speed up charger deployment. In the end, you benefit from faster network expansion and lower integration risk.

Engineering for scale
Our approach to work goes beyond just “supporting” protocols. Instead, we have deep-level knowledge of OCPP 1.6/2.0.1 and OCPI, handling complex firmware integrations and vendor variations that often get in the way of scaling. Our team maintains this expertise through continuous learning and active participation in global industry events and conferences.
Our software engineers have built and deployed protocol implementations for leading EV platforms, including projects with EV Connect and Greenlane. This means that we are able to solve real interoperability challenges across chargers, backends, and roaming platforms.
As you know, EV infrastructure evolves quickly. Our team has hands-on experience migrating EV charging platforms to newer protocol versions. This way, we help our partners adopt advanced capabilities without disrupting operations.
As members of the OCA, the organization responsible for the OCPP standard, we stay close to the evolution of the protocol and industry best practices.

Real EV networks rarely rely on a single charger vendor. We help our partners avoid vendor lock-in by building middleware that communicates across heterogeneous hardware. Whether it’s legacy stations or next-gen chargers, our team guarantees a unified EVSE backend experience for your team.
Beyond protocol implementation, Intelliarts integrates EV platforms with payment systems, energy management tools, and telematics. All this to ensure your entire ecosystem works as smoothly as possible.
Our longest partnership lasts over 15 years, reflecting the trust we build through ownership and reliable delivery. Long-lasting relationships are a priority for us so we stay involved after the initial implementation, helping evolve your EV solution and scale the infrastructure.
Having implemented OCPP and OCPI from scratch across multiple projects, we benefit from this experience to deliver integrations significantly faster than the industry average. This allows you to reduce time-to-market and scale your EV infrastructure with confidence.
Our solutions are designed to grow together with your infrastructure, from pilot deployments to nationwide networks with thousands of charging points. Our team builds scalable backend architectures and communication layers that support high transaction volumes and distributed fleets.

FAQ
What is the difference between OCPP and OCPI?
OCPP (Open Charge Point Protocol) handles the communication between a charging station and its management system. Meanwhile, OCPI (Open Charge Point Interface) is responsible for communication between different networks to allow for driver roaming and data sharing. In brief, OCPP connects the hardware to the software, whereas OCPI connects one charging provider to another.
How long does OCPP integration take?
The timeline depends on the scope. Standalone OCPP integration typically takes significantly less time, depending on charger complexity and vendor specifics. However, building a full-scale charging management system (CSMS) with OCPP integration, smart charging, billing, and roaming capabilities usually takes 6 to 12 months. At Intelliarts, our 9+ years in e-mobility and 25 years in software engineering help us streamline delivery and reduce time-to-market.
Can you support OCPP 1.6 and 2.0.1 simultaneously in the same system?
Yes, we can. Since the majority of charging stations still operate on OCPP 1.6, we typically implement backend architectures that support both versions in parallel. This allows you to gradually adopt OCPP 2.0.1 features while maintaining compatibility with existing chargers. We also adapt your CPMS/CSMS to handle the 2.0.1 version and enhance security profiles.
