Electric vehicle (EV) charging is entering a new era of simplicity and intelligence. The days of juggling multiple apps, RFID cards, and payment accounts for public charging are coming to an end. For years, drivers have been frustrated by a fragmented experience—often needing to download yet another app in the rain just to start a charging session. What users truly want is the “Tesla-like experience”: plug in, walk away, and let the system handle everything automatically.
Thanks to evolving standards such as ISO 15118 and regulatory frameworks like the EU’s Alternative Fuels Infrastructure Regulation (AFIR), this seamless, user-friendly approach is becoming achievable across all brands, networks, and markets.
Today, many charging solutions in the industry are becoming Plug & Charge ready, marking a significant milestone toward smarter, easier, and more secure electromobility. This blog post explores what ISO 15118 is, how Plug & Charge works, and why it matters for drivers, charging point operators, energy providers, and vehicle manufacturers. It also looks at how the industry is implementing these innovations—and what comes next, including bidirectional charging and future requirements driven by new regulations. Plug & Charge and ISO 15118 offer a future proof way to simplify and standardize EV charging, ensuring adaptability as technology and standards evolve.
Next, we’ll introduce ISO 15118 itself – the communication backbone enabling these advancements.
What Is ISO 15118?
ISO 15118 is an international standard that defines a common communication protocol between EVs and charging stations, covering both AC and DC charging. In essence, it’s the “language” that enables an electric car and a charger to communicate intelligently with each other. ISO 15118 establishes a communication network between the EV and charging station, enabling reliable message exchange. This protocol also defines a standardized communication interface for secure data transfer between vehicles and chargers. This standard allows for the secure, seamless, automated identification, authentication, and management of charging sessions. Instead of a charger being “dumb” and only providing power, an ISO 15118-enabled charger and car exchange data about who the car is, what it needs, and how to bill for the session – all without driver intervention. ISO 15118 is an international communication standard developed to ensure global interoperability. The International Electrotechnical Commission (IEC) collaborated with ISO as an international organization to develop the standard. A joint working group between ISO and IEC was responsible for creating and refining the ISO 15118 charge standard.
Key elements of ISO 15118
Secure Digital Certificates
Every ISO 15118-enabled EV and charger uses cryptographic certificates as a digital ID. This enables the car and station to automatically recognize and trust each other, thereby establishing a secure connection. A Public Key Infrastructure manages these certificates to ensure only authorized vehicles and chargers communicate. Public key infrastructures are used to manage digital certificates and secure authentication in Plug & Charge.
Encrypted Communication
All data exchanged (from authentication details to charging parameters) is protected by strong encryption (Transport Layer Security) to prevent eavesdropping or tampering. This keeps charging sessions tamper-proof and confidential, similar to secure online banking sessions.
Automatic Authentication & Authorization
The protocol supports a “Plug & Charge” feature, where plugging in the vehicle triggers automatic identity verification and payment authorization. No manual login or user action is needed at the charger – the car’s identity and the driver’s billing account are confirmed instantly over the cable.
The latest version of the standard (ISO 15118-20) introduces support for bidirectional charging, allowing energy to flow from the vehicle back to the grid or a building when appropriate. This opens the door to Vehicle-to-Grid (V2G) services, where EVs help balance the grid, as well as other use cases we’ll discuss later. (ISO 15118-20 also adds support for wireless charging, preparing for future technologies.) Overall, ISO 15118 aims to streamline the EV charging experience by making charging stations more intelligent and more connected. It uses modern data protocols and security techniques to ensure that charging an EV can be as simple, safe, and automated as possible – even across different car brands and charging networks. The ISO 15118 protocol operates across multiple layers of the OSI model, including the application layer for message exchange and the physical layer for data transfer over power line communication. By establishing a unified standard, ISO 15118 enhances interoperability (enabling any compliant car to work with any compliant charger). It lays the foundation for advanced features such as smart charging and V2G integration.
With an understanding of ISO 15118’s capabilities, let’s zoom in on “Plug & Charge,” the breakthrough feature it enables for effortless charging.
Plug & Charge Explained
“Plug & Charge” is the consumer-friendly name for ISO 15118’s automatic authentication and billing feature. It means exactly what it sounds like: you plug your EV into a compatible charging station, and your charging session starts immediately as the car and charger “handshake” and authorize in the background. The charge process involves establishing a secure charge connection between the EV and the compatible charge point, ensuring reliable communication. No apps, no cards, no SMS codes – just plug in and charge. The EV effectively logs into the charger on your behalf.
Here’s what Plug & Charge brings to the table
No RFID Cards Or Membership Fobs Are Needed
The vehicle’s digital certificate serves as both its ID and payment credential, so you don’t have to swipe an RFID card or enter a PIN to start charging. Your account details (through your car maker or service provider) are linked to the car itself.
No Mobile Apps or Manual Login
There’s no need to pull out a smartphone, scan QR codes, or navigate a touchscreen app at the station. Authentication occurs automatically over the charging cable as soon as the connection is established. This eliminates the need to juggle multiple apps or register with each charging network.
Automatic, Transparent Billing
Once the car and charger are verified, the station securely communicates with the back-end billing system to authorize payment using the driver’s on-file account. The charging session is then billed automatically – for instance, to the driver’s enrolled subscription or credit card – with no additional steps required for the user. You’ll typically get a notification or receipt from your service provider, but you don’t need to do anything on the spot.
Effortless User Experience
For the driver, it feels instantaneous. In fact, the entire authentication and authorization process typically completes in just a few seconds, making it nearly invisible to the user. You plug in, hear a click, and maybe see the charger indicator light up; then you can walk away. Charging starts as quickly as the car and station can ramp up power. It’s a truly plug-and-go experience, finally delivering on what EV owners have been craving: maximum convenience.
With Plug & Charge, drivers can trust that the charger “knows” who they are and how to securely bill them. This feature is enabled by the secure certificate exchange defined in ISO 15118. When you connect your car, the EV and charger perform a cryptographic handshake – exchanging digital certificates and validating each other – to ensure that an authorized account is associated with that EV. The charge certificate is created by the vehicle manufacturer and is essential for enabling Plug & Charge functionality. The certificate protects vehicle and user data by securing communication through encryption and two way authentication, ensuring that all data is safe during the charge process. Only then is power delivered. All of this happens under the hood, without hassle for the driver, and with robust security measures in place. In short, Plug & Charge makes charging an EV as simple as pumping gas – only smarter and safer.
To use Plug & Charge, both the vehicle and the charge point equipment must be compatible and meet certain technical requirements. Successful Plug & Charge depends on both the vehicle and the charge point equipment meeting these requirements for secure and seamless charging.
Drivers typically activate Plug & Charge using the EV manufacturer app, which is used to install plug certificates and manage software updates required for Plug & Charge. A software update may be necessary to enable Plug & Charge charge capabilities, and the charge work is automated once the requirements are met.
Now that we’ve explained what Plug & Charge is, let’s examine why it’s such a game-changer for all parties in the EV industry – from drivers to charging operators to car manufacturers.
Why Plug & Charge Matters for the Industry
Implementing Plug & Charge isn’t just about convenience – it brings significant benefits to every stakeholder in the EV ecosystem. Here’s how this technology positively impacts different groups:
EV Drivers
For drivers, Plug & Charge offers a frictionless charging experience. It eliminates the need for apps, cards, or any manual authentication, so charging becomes as simple as “plug in and go”. Sessions start faster with no delay in getting authorization, which can save time (especially in bad weather or at night). Importantly, security is also stronger – the encrypted, certificate-based handshake ensures that your payment details and account information are protected by banking-grade security on every charge. Many EV drivers have experienced frustration with traditional charging methods, making Plug & Charge a welcome improvement for a large user base. In short, Plug & Charge improves convenience and peace of mind for drivers, making EV ownership more enjoyable.
Charge Point Operators (CPOs)
For charging network operators and site owners, Plug & Charge can streamline operations and reduce costs. With automatic authentication and billing, there are fewer support issues (e.g., lost RFID cards or app glitches) and fewer customer service calls about charging access. The process is so seamless that it reduces queuing and idle time, potentially increasing station throughput and revenue (cars start charging immediately, no lag). Plug & Charge also opens up new possibilities for intelligent energy management, such as integrating dynamic pricing or load balancing based on the data exchanged with the vehicle. In the future, operators could even earn revenue through V2G services (using connected EVs to sell energy or regulate the grid). Finally, using a standardized system like ISO 15118 simplifies interoperability and roaming, allowing CPOs to efficiently serve drivers from different networks or countries without requiring custom integrations. ISO 15118, officially titled as a standard for road vehicles, defines the vehicle-to-grid communication interface and is central to secure, smart charging. When considering alternative protocols, the DIN Spec 70121 standard (also known as ‘autocharge’) is sometimes used, but it relies on MAC addresses and lacks a certificate chain, making it less secure than ISO 15118. Overall, Plug & Charge can lower operational overhead while boosting user satisfaction for charging providers.
EV Manufacturers
Automakers benefit from Plug & Charge by offering a better customer experience. An EV that supports Plug & Charge provides seamless integration with the charging infrastructure, which can be a strong selling point. Drivers of these cars enjoy a premium, hassle-free charging experience that reflects well on the vehicle’s brand. In practical terms, implementing the ISO 15118 standard in the car ensures it can charge effortlessly across a wide range of charging networks, improving compatibility and customer confidence. The vehicle manufacturer is responsible for creating and providing the digital certificates used for secure Plug & Charge communication, and compatibility or software updates from the vehicle manufacturer are essential for enabling this functionality. The Volkswagen Group, for example, is actively rolling out Plug & Charge updates across its brands, demonstrating industry adoption. This enhanced customer satisfaction can translate to greater loyalty and differentiation in a competitive EV market. Additionally, ISO 15118 support helps future-proof the vehicle for upcoming capabilities, such as wireless charging and Vehicle-to-Grid (V2G), aligning the manufacturer with the latest technology trends. By adopting common standards, automakers also reduce complexity (one universal approach instead of many proprietary systems), which can lower development costs and foster an ecosystem where any compliant car can use any compliant charger. In short, Plug & Charge enables a “charge anywhere, easily” promise, making EVs more appealing to consumers and more straightforward for manufacturers to integrate globally. The Octopus Electroverse team is one example of a group assisting with vehicle certification, digital certificate installation, and ensuring secure communication between EVs and charging stations to support Plug & Charge deployment.

Plug & Charge is transforming the process of charging electric vehicles and relies on advanced electric vehicle supply equipment to deliver seamless, secure, and user-friendly charging. It’s a key step in making EV charging as intuitive as it needs to be for mass adoption.
Having explored the broader benefits, let’s look at what this evolution means for the industry and how Plug & Charge is being implemented across modern charging solutions.
Public Charging Infrastructure
Public charging infrastructure is at the heart of the electric vehicle revolution, serving as the bridge between EV drivers and the energy they need to stay mobile. As electric vehicles become increasingly popular, the demand for accessible, reliable, and user-friendly public charging points continues to surge. Modern public charging stations are no longer just simple outlets—they are sophisticated hubs equipped with advanced features like smart charging, wireless charging, and secure communication interfaces that transform the electric car charging experience.
The adoption of international standards such as ISO 15118 is accelerating the evolution of public charging infrastructure. By enabling Plug & Charge functionality, these standards allow EV drivers to simply plug their vehicles into a compatible charging station and start charging instantly, without the need for apps or cards. This seamless process is made possible by secure communication protocols that automatically identify the vehicle and authorize the charging session, ensuring both convenience and security.
Governments and charging station operators are investing heavily in expanding and upgrading public charging networks to keep pace with the growing number of EVs on the road. The focus is on deploying charging stations that not only meet current needs but are also future-proof—ready to support innovations like wireless charging and dynamic load management. For EV drivers, this means more locations to charge, faster charging rates, and a consistently smooth experience across different networks and vehicle brands.
Ultimately, the advancement of public charging infrastructure—powered by smart technology and robust communication standards—plays a pivotal role in making electric car charging as effortless and dependable as traditional refueling, helping to drive the widespread adoption of EVs.
Charging Station Operators
Charging station operators are the backbone of the electric vehicle charging ecosystem, responsible for delivering the infrastructure that powers the transition to sustainable mobility. Their role extends far beyond simply installing charging stations; operators must ensure that every charging station is equipped with the latest charge technology, supports a wide range of electric vehicle models, and delivers a secure, seamless charging experience for EV drivers.
To achieve this, charging station operators are increasingly adopting international standards like ISO 15118, which enable Plug & Charge functionality and secure communication between vehicles and charging stations. By implementing robust digital certificate management systems, operators can guarantee that each charging session is authenticated and authorized automatically, eliminating the need for RFID cards or mobile apps. This not only streamlines the charging process for EV drivers but also enhances security by protecting vehicle and user data through encrypted communication networks.
Staying ahead in the rapidly evolving EV market requires operators to continuously update their infrastructure, integrating new features such as higher power charging, smart charging capabilities, and compatibility with the latest electric vehicle models. By embracing Plug & Charge and other advanced charge technologies, charging station operators can offer a superior charging experience, attract more users, and contribute to the growth of electric mobility.
In summary, charging station operators who invest in secure, future-ready communication and network solutions are well-positioned to meet the needs of today’s EV drivers and adapt to the innovations of tomorrow, ensuring their place at the forefront of the electric vehicle revolution.
Why This Is a Major Step for the EV Charging Industry
Enabling Plug & Charge represents a significant milestone for manufacturers and infrastructure operators. By supporting ISO 15118, charging stations can authenticate and charge compatible vehicles the moment they are plugged in—no apps, cards, or manual steps required. This shift elevates user experience, increases security, and positions next-generation chargers among the most advanced in today’s market.
Implementation of ISO 15118 Plug & Charge
Complete TLS Security & Certificate Management
Modern charging systems are integrating the ISO 15118 Public Key Infrastructure (PKI), allowing chargers to manage digital certificate exchanges directly with the vehicle. Encrypted communication, digital signatures, and strict identity verification between the EV and the charging station protect each Plug & Charge session. This TLS-based security model prevents unauthorized charging, fraud, and tampering, making it a baseline requirement for next-generation EV infrastructure.
Seamless EV–Charger Handshake
The moment a driver plugs in an EV that supports Plug & Charge, our charger’s controller initiates an ISO 15118 handshake. In a few seconds, the charger and car exchange certificates, and the contract is validated. Our charger obtains charging authorization from the backend, and the energy flow begins. This process is entirely automated. From the driver’s perspective, the charger simply “recognizes” the vehicle and starts charging. Our chargers execute this handshake reliably and quickly, providing that truly effortless experience for the end user.
Ready-To-Scale Backend Infrastructure
Supporting Plug & Charge requires more than capable hardware; it also depends on backend systems that can manage contract certificates, roaming authentication, session data, and operator integrations. Industry-ready platforms now provide scalable infrastructures that can handle certificate validation and compatibility with central certificate authorities (such as the Hubject V2G Root CA). This ensures that any EV with a valid contract can be authenticated across different networks, helping operators deploy Plug & Charge smoothly—whether they manage a handful of chargers or large, distributed networks.
Achieving Plug & Charge capability sets modern charging solutions apart in terms of technology and regulatory readiness. A large share of currently installed charging stations still lack ISO 15118 support or require major updates. In contrast, new-generation hardware is increasingly delivered Plug & Charge–ready out of the box.
This future-proofing extends beyond today’s requirements. Many manufacturers already design their systems with the flexibility to support upcoming ISO 15118-20 features, such as advanced communication functions and bidirectional energy flows. ISO 15118-20 defines a grid communication interface for secure, bidirectional energy transfer between electric vehicles and the electrical grid. It also enables vehicle to grid communication, allowing vehicles to participate in grid services and support energy management. Notably, an increasing number of tenders and networks across Europe are already requiring ISO 15118 capability in new charging installations.
Vehicles vehicle to grid functionality is a key feature of next-generation charging infrastructure, supporting advanced V2G services and enabling smart interaction between EVs and the grid.
Plug & Charge is only the beginning. The next major frontier—enabled by ISO 15118-20—is bidirectional charging, and the industry is already moving toward making this a practical reality. Plug & Charge is advancing the way of charging electric vehicles by integrating smart communication protocols for seamless, secure, and user-friendly charging experiences.
The Next Frontier: Bidirectional Charging | ISO 15118-20
Plug & Charge significantly enhances the charging experience, but the vision behind ISO 15118 extends far beyond simply drawing energy from the grid. The next major frontier in EV infrastructure is bidirectional power flow—the ability for vehicles not only to charge, but also to return energy when needed. This concept, known as V2X (vehicle-to-everything), is enabled by ISO 15118-20 and positions electric vehicles as active, intelligent components of future energy systems rather than passive consumers. ISO 15118-20 defines a grid communication interface and vehicle to grid communication protocols for secure, bidirectional energy transfer, enabling smart charging and Plug & Charge functionalities within V2G systems.
Industry players are already developing future-proof solutions for bidirectional charging, and this technology will unlock several key use cases:
Vehicle-to-Grid (V2G)
This scenario involves an EV sending electricity from its battery back to the electric grid. Imagine thousands of EVs acting as a distributed energy resource, feeding power into the grid during peak demand or when renewable energy is scarce. V2G can help stabilize the grid, reduce strain during peak hours, and optimize the use of renewable energy by storing excess energy and returning it when needed. In return, EV owners might earn incentives or credits for supplying power. ISO 15118-20 provides the vehicle to grid communication required for V2G, coordinating when the car should discharge and ensuring it’s done securely and with the owner’s permission. This is a cornerstone of future smart grids, as EVs en masse could act like a massive virtual power plant to balance supply and demand.
Vehicle-to-Home (V2H)
In this use case, an EV can power a home (or part of it). The EV’s battery serves as a backup power source or an energy-use optimization tool in a household. For example, during an outage, a V2H-capable EV could maintain power to the lights, refrigerator, and WiFi for several hours. Even in normal conditions, homeowners might use V2H to save money – charging the car when electricity is cheap (or solar panels are active) and then using the car’s battery to power the home during expensive peak hours. This effectively turns the EV into a mobile residential energy storage unit. ISO 15118-20 facilitates this by enabling the EV, charger, and home energy system to communicate about their respective power needs and capacities. V2H can increase consumers’ energy independence and resilience.
Vehicle-to-Building (V2B)
Similar to V2H, V2B refers to using EVs to supply energy to larger buildings, including commercial facilities. For example, a fleet of company EVs parked at an office could collectively support the building’s power during peak times, cutting energy costs or providing emergency power. While the scale is larger (and would likely involve multiple vehicles to have a significant impact), the concept remains the same: EVs become mobile energy storage for a building. This could be useful for hospitals, schools, or businesses that have critical loads or demand charge costs. V2B implementations may require coordinating multiple vehicles and more sophisticated energy management, but ISO 15118-20’s communication protocol is designed to handle these complex interactions through a common standard.
Why is bidirectional charging such a big deal? Because it has the potential to revolutionize our thinking about cars and energy. Instead of cars being passive consumers of electricity, they become active participants in the energy ecosystem. Collectively, EVs can store enormous amounts of energy (imagine millions of cars plugged in during the day, soaking up solar power, then giving some back to the grid in the evening). This could improve grid stability, enhance the use of renewable energy, and even provide financial benefits to EV owners who can sell electricity from their battery storage.
ISO 15118-20 is the framework that unlocks this capability by standardizing bidirectional power transfer between vehicles and chargers. It defines the messages needed for an EV to deliver energy and for the grid/charger to safely accept it, including all necessary authentication and controls. The communication interface established by ISO 15118-20 enables smart coordination between vehicles, chargers, and the grid for secure and efficient energy management. As a result, many experts see bidirectional charging as a cornerstone of future, innovative energy systems in which the transportation and electricity sectors converge. EV chargers will no longer be just fueling points, but rather intelligent energy nodes that can both draw and supply power as situations demand.
The industry widely acknowledges the transformative potential of bidirectional charging. For this reason, many manufacturers and infrastructure developers are actively building and testing V2G (vehicle-to-grid) and V2H (vehicle-to-home) capabilities in alignment with ISO 15118-20. The goal is to ensure that future charging systems do more than simply deliver energy to a vehicle — they will also enable drivers and operators to use the vehicle’s stored energy in new, valuable ways. This includes supporting the grid during peak demand, powering homes or buildings, or serving as a reliable backup source during outages.
By investing in these technologies today, industry stakeholders position themselves — and their partners — ahead of the curve as bidirectional EV charging moves toward mainstream adoption.
Now, let’s connect these technological advances to the evolving regulatory landscape. The EU’s AFIR regulation is accelerating the deployment of standardized communication protocols such as ISO 15118, and understanding why this matters now is crucial for everyone involved in the charging ecosystem.
AFIR: Why It All Matters Now?
The Alternative Fuels Infrastructure Regulation (AFIR) is the European Union’s latest policy push to improve EV charging infrastructure rapidly. It came into effect in 2024 and is poised to transform the charging experience across Europe by setting standard requirements and targets. In essence, AFIR aims to ensure that charging an EV is as convenient, transparent, and standardized as possible, no matter where you are in the EU.
Key objectives of AFIR include expanding the network of charging stations (with specific targets for coverage and capacity), achieving full interoperability of charging infrastructure, and providing comprehensive user information and payment options at all chargers. [35] For EV drivers, this means things like knowing that along major highways there will be fast chargers every 60 km, that every public charger will display pricing clearly in €/kWh, and that you can pay easily (e.g., with a credit card or contactless method) if you’re not enrolled in a particular network. In short, AFIR is about making public charging ubiquitous, user-friendly, and uniform across different countries and operators.
ISO 15118 and Plug & Charge align perfectly with AFIR’s goals. To achieve full interoperability and a seamless user experience, having a common communication standard, such as ISO 15118, is critical. In fact, AFIR’s implementing framework explicitly requires new charging stations to support ISO 15118 in the coming years. New chargers must meet certain technical requirements, including support for ISO 15118 and Plug & Charge, to ensure secure and standardized charging sessions. The regulation and its delegated acts mandate that:
Starting in January 2026, all newly installed public AC chargers in the EU must support ISO 15118-2 (Plug & Charge) functionality. This effectively means any new public charger should be capable of automatic EV authentication and billing. The aim is for drivers to be able to drive up to any new station and simply plug in to charge, thereby improving convenience and eliminating barriers between different charging networks. These chargers must also meet certain technical requirements to guarantee compatibility and security.
By January 2027, the requirement extends to ISO 15118-20 support for all new or upgraded chargers (public and even private). This ensures that more advanced features, such as bidirectional charging and wireless charging (as defined in the -20 standard), become standard capabilities in the infrastructure moving forward. In other words, Europe is future-proofing its charging network: chargers will need to be ready for V2G and other next-gen functionalities by that date.
These timelines underscore that Plug & Charge is not just a niche feature – it’s the new baseline that regulators are insisting on. AFIR essentially accelerates the adoption of Plug & Charge by treating it as a compliance matter for manufacturers and operators. The reasoning is clear: a harmonized, secure, and easy charging experience will encourage EV adoption, and interoperability benefits everyone from consumers to businesses. By mandating a standard like ISO 15118, AFIR removes uncertainty (all stakeholders can build to the same spec) and ensures that innovations like Plug & Charge and V2G become widespread across Europe on a clear timetable.
The industry has long anticipated this regulatory shift, and many charging solution providers are now positioned to meet AFIR’s requirements. With Plug & Charge functionality becoming standard across new infrastructure, manufacturers and operators are already aligning with the ISO 15118-2 mandate ahead of the 2026 deadline. Parallel development efforts for bidirectional charging ensure that hardware and backend systems are prepared for the ISO 15118-20 requirements, which will come into force by 2027.
For charge point operators and partners across the sector, this means that next-generation infrastructure is being built with regulatory readiness in mind, helping prevent compliance gaps as the rules evolve.
User Experience
With Plug & Charge support, our chargers provide the kind of seamless, user-friendly experience that AFIR wants to make universal. Drivers will find our stations meet the upcoming expectations for ease of use (no app, instant start), which can increase satisfaction and usage.
Interoperability & Standardization
Adopting ISO 15118 ensures that chargers communicate through a shared, globally recognized protocol. This enhances compatibility across multiple EV brands, e-mobility service providers, and charging networks, fulfilling AFIR’s emphasis on interoperability. Only a compatible charge point can provide seamless Plug & Charge functionality, ensuring that as long as an EV supports Plug & Charge, it can operate across compliant charging networks throughout the EU.
Future Compliance
As AFIR accelerates the adoption of smart charging, V2G capabilities, and integrated energy-market communication, industry players are preparing by developing hardware and software that support these advanced features. This includes backend systems capable of secure data exchange, contract certificate handling, dynamic pricing integration, and support for grid-responsive charging. When future regulations require V2G functionality in public infrastructure, the groundwork will already be in place.
In summary*, AFIR highlights the importance of steps already underway across the EV charging sector. It matters now because the entire industry is converging on the same core innovations: Plug & Charge and, soon, bidirectional charging. AFIR is driving the adoption of standardized solutions for charging electric vehicles across Europe. Stakeholders who adopt AFIR-aligned solutions are not only meeting upcoming regulatory demands—they are positioning themselves ahead of them.*
Next, we’ll look at what these developments mean for the future of EV charging and how the broader industry is contributing to a more innovative, more connected electromobility ecosystem.
