The real cost of fragmentation in the EV charging infrastructure

What does 'fragmentation' mean in EV charging?

Imagine the following scenario: a driver arrives at a charging station with a nearly empty battery, happy to see a charger. In the worst-case scenario, it is raining and the temperatures are low. The driver connects the car, swipes their bank card, and the payment system fails. Fragmentation in EV charging refers to the growing complexity behind what seems like a simple act: plugging in and paying. Today, drivers can initiate a session through roaming cards, mobile apps, QR codes, or direct card payments, each relying on different technologies and flows.

Behind the scenes, this is supported by a mix of systems – payment service providers, charging hardware, roaming platforms, and charge point management platforms – that must all work together seamlessly. On top of that, operators must navigate a patchwork of regulations, from AFIR requirements for ad hoc payments to country-specific VAT rules and local compliance standards. The result is that what used to be a relatively straightforward backend process has evolved into a multi-layered system, where each additional payment option, integration, or regulation adds another layer of operational complexity

Why fragmentation is advancing

Fragmentation in EV charging is driven by several structural shifts in the market. Regulation is a key factor: with frameworks like AFIR mandating ad hoc payments, operators must now support open, accessible payment methods such as cards and QR flows, moving away from closed systems and introducing additional complexity. At the same time, the expansion of roaming networks brings more parties into every transaction. Think CPOs, MSPs, PSPs, roaming hubs, etc., which results in increased data exchange and, inevitably, more potential points of failure.

Consumer expectations are also reshaping the landscape. Drivers now expect the same seamless experience they get in retail, with contactless payments, mobile wallets, and instant access, making traditional charge cards feel outdated.

Finally, the fast paced scale of growth amplifies all of this: with EV charging infrastructure expanding by over 700% in just five years, transaction volumes have surged, and with them, the likelihood of errors, inconsistencies, and operational strain.

The hidden cost of fragmentation

The cost of fragmentation in EV charging is often underestimated because it is spread across operations, finance, and customer experience. Operationally, managing multiple integrations, payment providers, and systems creates a web of dependencies where even a simple issue can require coordination across internal teams and external partners. Because payments are not the core business of most CPOs, resolving these issues is often slower and more resource-intensive.

Financially, fragmentation leads to leakage: failed transactions, chargebacks, hidden fees, and delayed settlements all erode margins, while limited visibility makes it difficult to pinpoint where losses actually happen. On top of this, the administrative burden grows as operators juggle multiple PSP contracts, roaming agreements, and varying pricing models, reporting formats, and compliance requirements.

Ultimately, these inefficiencies surface where it matters most: in the driver experience. When payments fail, charging sessions don’t start, revenue is immediately lost, and drivers simply move to a competitor. Negative experiences are quickly shared through reviews, amplifying the impact and making fragmentation not just an operational issue, but a direct threat to growth and trust.

The impact on the entire payment ecosystem

Fragmentation doesn’t just affect one part of the value chain, but it reshapes the entire EV charging ecosystem. For CPOs, it creates an imbalance: they carry full responsibility for the charging experience, yet lack end-to-end control, forcing them to coordinate across fragmented systems, providers, and regulations. It also means CPOs have to get their own PSP contracts, which, for a smaller- to mid-sized CPO, can cost more than they produce, as you need volume to create a profit. Working with a PSP when the volume is not high enough often means it will end up costing money.

For EV drivers, this complexity translates into inconsistency; payment methods that work in one location may fail in another, quickly eroding trust when reliability matters most.

Manufacturers and installers are also impacted, as they must continuously adapt hardware to meet evolving requirements, from integrating payment terminals to enabling QR-based flows in line with AFIR. Meanwhile, platforms and PSPs face a strategic crossroads: either expand into full payment orchestration to manage the growing complexity, or remain limited to partial integrations, accepting a smaller role in an increasingly interconnected payment landscape

Fragmentation is a growth problem, not just a tech problem

Fragmentation in EV charging has become a growth problem rather than a technical one. As networks scale, the real issue is not simply fixing individual payment failures but understanding everything required to deliver a reliable, seamless payment experience across markets, systems, and customer expectations. What once seemed manageable as a collection of separate integrations now creates operational strain that slows expansion, increases costs, and impacts driver trust. The industry does not necessarily need more payment methods or additional tools; it needs less fragmentation between them. Sustainable growth depends on simplifying the payment ecosystem, reducing operational complexity, and creating a consistent experience that can scale alongside the EV market.
