How to Build a Future-proof EV Charging CPO Tech Stack in 2025
Read Time:10minutes
Jul 11, 2025
The electric vehicle revolution is accelerating, and Charge Point Operators (CPOs) are at the forefront of this transformation.
As the demand for reliable and accessible charging infrastructure grows, CPOs face the challenge of scaling their operations while maintaining flexibility and delivering exceptional customer experiences.
After all, the demand for reliable and accessible charging infrastructure keeps intensifying. According to the International Energy Agency, the number of public EV chargers worldwide has doubled since 2022, surpassing 5 million in 2025.
To stay ahead, Charge Point Operators need a tech stack that supports growth, adapts quickly, and gives full control over data, integrations, and customer experience. This means working with open APIs, staying flexible on vendors, enabling roaming from day one, and building a setup that doesn’t crack under pressure.
Here’s how to build a CPO tech stack that moves as fast as the market.
How to launch EV charging services quickly with open APIs
In 2025, speed is everything. The faster you can connect systems, launch services, and respond to changes, the better you compete in a fast-moving market.
Open APIs make this possible. Flexible API eliminate the need for custom code or long development cycles. Your systems become plug-and-play, and your tech team stays in control.
With open APIs, you can:
Integrate chargers, payments, and apps in days: Standardised connections let you go live faster, without waiting on vendors.
Add services and features when they fit your roadmap: Whether it's smart charging, fleet tools, or loyalty programmes, you connect what you need, when you’re ready.
Partner with roaming platforms and third parties: Open protocols like OCPI simplify roaming integrations, so you can expand your network without delays.
Open APIs keep your tech stack agile. You control what’s connected, what’s next, and how fast you move.
How to keep your EV charging tech stack vendor-agnostic
Your tech stack should move with your business. When it’s locked into a single vendor, you’re stuck with their tools, pricing, and limitations.
A vendor-agnostic setup gives you more room to grow. It’s designed to support different providers, tools, and features, so you can make decisions based on what your business needs, not on what your current system allows.
With a flexible stack, you can:
Work with multiple hardware providers: Choose the chargers that fit each location, project, or customer segment without compatibility issues.
Swap or upgrade components when needed: Change your payment solution, CRM, or charge point brand without reworking your full setup.
Set your own direction: Adapt to new partnerships, regulations, or business models without delays or roadblocks.
The more choice you have, the easier it is to adapt. A flexible tech stack gives you options, and options give you control.
How to get full data access from your EV charging network
Running a charging network without clear data is like flying blind. You might keep things running, but you miss opportunities, overlook problems, and struggle to plan your next move.
A transparent tech stack changes that. It puts real-time, reliable data in your hands, so you know exactly how your network is performing and where to focus next.
With full data visibility, you can:
Monitor charger uptime and energy usage in real time: See which stations are online, how much power they’re delivering, and where issues need attention. This helps you improve reliability and reduce downtime.
Understand user behaviour and session trends: Get insight into who’s charging, when, and how often. Spot usage patterns, peak hours, and location performance to guide operational decisions.
Track costs and revenue across all sites: Break down margins per location, measure pricing effectiveness, and forecast returns more accurately. Know where you're profitable and where adjustments are needed.
Data gives you leverage. It helps you fix faster, plan smarter, and grow with confidence. You don’t need to guess what’s working, the numbers are right there.
How to enable EV roaming with OCPI and roaming platforms
EV drivers expect charging to work everywhere: at home, at work, on the road. They don’t think in terms of networks or providers. They just want to plug in and go.
Roaming makes that possible. Your tech stack should make it effortless.
When your system supports roaming protocols like OCPI, you open the door to more partnerships without extra complexity. You avoid the delays, spreadsheets, and manual updates that slow down collaboration.
With roaming-ready tools in place, you can:
Onboard roaming partners without manual effort: Skip the back-and-forth setup process. Standardised communication means faster partner launches and fewer support issues.
Keep availability, pricing, and authentication in sync: Real-time data sharing guarantees that what drivers see in apps and maps reflects what’s actually available on the ground.
Expand your reach through platforms like Hubject or Gireve: Tap into established networks with thousands of roaming-capable chargers. Increase visibility and get more usage out of your infrastructure.
A strong roaming setup gives drivers confidence and gives your network more value. More sessions. More satisfied users. More business without building new sites.
How to scale an EV charging network without losing efficiency
Growth is the goal, but it also adds layers. More chargers, more users, more partners, more data. Without the right systems in place, scale can lead to chaos.
A well-designed tech stack helps you handle expansion without losing control. It gives your team the tools to manage more sites, more complexity, and more demand without adding unnecessary overhead.
To scale smoothly, focus on tools that provide:
Role-based access for teams and partners: Let different users see and manage what they need, without opening up the entire system. Give installers, operators, support teams, and business partners the right access level for their job.
Smart charging features like load balancing and dynamic pricing: Use intelligent energy distribution to prevent overloads and maximise efficiency. Adjust pricing based on time, location, or usage to keep your network profitable and balanced.
Cloud-native infrastructure that adjusts with your needs: Avoid the limits of on-prem systems. A cloud-based setup scales automatically, supports updates without downtime, and keeps performance consistent as your network grows.
With the right tech foundation, you stay in control even as things get bigger and faster. Your operations remain efficient. Your team stays focused. And your customers get a charging experience that works. Every time.
