How to choose an EV charging platform for your network in Europe

Europe's charging market isn't short on vendors, it's short on platforms that can actually prove their AFIR, hardware, roaming, VAT and support claims before you sign anything.

For a charge point operator (CPO) or e-Mobility Service Provider (EMSP) evaluating a Charge Point Management System (CPMS), five things usually decide the choice: regulatory compliance, hardware compatibility, roaming reach, cross-border VAT handling, and support. This guide walks through each, with the specific questions worth asking before you sign anything.

What an EV charging platform must do

A CPMS is the software layer that connects, monitors and controls charging stations, manages sessions and payments, and exchanges data with roaming partners and back-office systems.

It's the operational backbone underneath the charging network, regardless of who owns the hardware or the site.

AFIR compliance is now the baseline

The Alternative Fuels Infrastructure Regulation (AFIR, EU 2023/1804) has been in force across the EU since 13 April 2024. All publicly accessible charging points had to be digitally connected by 14 October 2024.

Ad hoc payment without a subscription or app has been mandatory since the regulation took effect, and charging points built or renovated after those dates must support smart recharging. Requirements continue to tighten through 2030, including newer technical mandates such as EN ISO 15118-2:2016 support for AC stations from January 2026.

Ask specifically how a platform handles ad hoc payment without an account, how pricing transparency is displayed at the charge point, and how the vendor tracks upcoming AFIR deadlines rather than only today's requirements.

The Virta guide to AFIR covers the regulation's requirements in more detail.

Hardware compatibility caps network growth

A platform is only as useful as the hardware it can actually run. Networks that grow by acquisition, or by mixing vendors across markets, need a CPMS that doesn't force a hardware replacement every time.

Virta Hub, for example, is compatible with over 2,000 charging station models, a figure worth checking against any vendor's own compatible chargers list rather than taking on faith.

Ask concretely which charger brands are already integrated, what the process and timeline is for onboarding a brand that isn't, and whether adding new hardware requires a new commercial agreement or just a technical integration.

OCPP alone isn't a differentiator

Nearly every modern CPMS supports the Open Charge Point Protocol (OCPP), so OCPP support alone isn't meaningful.

What matters more is how a vendor handles OCPP version differences across older and newer hardware, and how quickly they roll out support for a specific charger model your network already uses or is planning to buy.

Roaming reach decides your revenue

A charging station that only your own app can unlock earns less than one visible across roaming partners.

The Open Charge Point Interface (OCPI) protocol is what makes roaming between different CPOs and EMSPs possible, and AFIR itself reinforces this by requiring CPOs not to discriminate against EMSPs, including on pricing.

Virta Managed Roaming connects a network to the wider Virta Network via two major roaming hubs, Hubject and Gireve, giving access to over 800,000 charge points across more than 60 countries without negotiating a separate agreement per partner.

"With Virta Roaming, our members can access a wide charging network – that is an important advantage for us," says Niila Rajala, CEO at AL-Lataus.

That kind of reach only matters if it converts into actual usage. More visibility across roaming partners' apps generally means more sessions on a network's own chargers, since drivers charge wherever is nearest and cheapest rather than only within their home provider's app.

Built-in hubs vs. bilateral agreements

Some platforms include a roaming hub as a built-in feature, connecting a network to multiple EMSPs through a single integration. Others require negotiating and maintaining bilateral agreements with each roaming partner individually, which scales poorly as a network expands across more countries.

For a network with ambitions across several European markets, the built-in hub model generally reduces both integration time and ongoing operational overhead.

Where VAT handling quietly falls short

Running a charging network across several European countries means dealing with different VAT rates, registration requirements, and reverse-charge rules for cross-border transactions.

Most platforms leave this entirely to the operator, meaning separate accounting relationships in every market a network touches.

The Virta platform includes VAT management as a dedicated function within its pricing and settlement engine, handling cross-border VAT logic automatically for roaming-in transactions as part of the monthly payout. This removes a genuinely underestimated cost for larger CPOs and network owners operating in several VAT jurisdictions.

Ask any vendor specifically which transaction types their VAT handling covers, and which, if any, still require manual reconciliation, since automation in this area is rarely all-or-nothing across every transaction type a network generates.

Energy management affects cost and speed

As DC and high-power charging sites scale, the local grid connection often becomes the real constraint, not the number of physical chargers a site could otherwise support.

A platform with genuine dynamic load management can allocate available power in real time across active sessions, letting a network add chargers within existing grid capacity rather than paying for a grid upgrade immediately.

For sites already hitting this limit, this Virta blog post on scaling a DC charging network with battery storage walks through how load management and on-site storage work together in practice.

Ask any vendor whether load management is dynamic or static, whether it integrates with on-site solar or battery storage, and whether it supports time-of-use pricing, since all three affect how much a network can grow before the next infrastructure investment becomes unavoidable.

Reliability and support matter most

A charger going offline outside your own working hours needs a response regardless of time zone, and this is where platform choice shows up in driver experience rather than on a feature comparison sheet.

Ask about self-healing diagnostics, remote firmware management, and published uptime data, not just an SLA figure in a contract.

Support language coverage matters specifically for European networks spanning several markets. Virta, for example, offers support in English around the clock, with Finnish, French, German and Swedish covered during extended business hours, at no cost to the caller.

For a network operating across multiple countries, ask whether support is offered in the languages your own site managers and drivers actually use, not just English.

Evaluate the vendor's compliance roadmap

AFIR's requirements are phased through 2030, and standards like OCPP and OCPI continue to evolve.

A platform that satisfies every current requirement but has no clear plan for what's coming next puts the compliance burden back on the operator.

Ask the vendor directly how they've handled past regulatory deadlines, and what's already built for the requirements still ahead.

Before signing with a CPMS vendor in Europe, get clear answers on:

• AFIR compliance: where the platform stands today, and a documented plan for requirements through 2030.
• Hardware compatibility: the exact number and range of charger makes and models already supported.
• Roaming model: whether roaming runs through a built-in hub or requires bilateral agreements per partner, and what network reach that actually delivers.
• Cross-border VAT: which scenarios are automated, and which still require manual handling.
• Load management: whether it is dynamic or adaptive and whether it integrates with on-site renewables or storage.
• Support coverage: what it looks like by language and time zone, and what uptime data the vendor is willing to share.
• Regulatory track record: how the vendor handled past deadlines, as a proxy for how they'll handle future ones.

A platform that answers all seven clearly is one built for how European charging regulation and operations actually work, not just for a sales demo.

Virta Hub is built around this exact set of requirements, for operators evaluating what a CPMS needs to cover across a European network.
