Electric vehicle owners in Spain can charge at compatible stations by simply plugging in, without using an app or card. No payment screen is needed. Plug & Charge uses digital certificates and authenticated communication to simplify the process, while Tesla Superchargers and select networks offer similar automatic authentication. A similar experience for drivers does not necessarily mean the same technology is at work.
Plug & Charge operates on the ISO 15118 standard, which governs digital communication between a vehicle and a charging station. When a compatible vehicle connects to a compatible charging point, the system presents credentials linked to a charging contract. The service validates them before the session begins. Authorization and billing run through the associated contract, with no separate card or app interaction at the charger.
How Plug & Charge Works
At the core of Plug & Charge is a digital exchange. The vehicle stores a digital certificate tied to the owner’s charging contract. Once the car is plugged in, it exchanges data with the charger, and the charging service checks the certificate before authorizing energy delivery. The system relies on verified credentials, not a simple vehicle identifier or payment-card interaction.
Smooth charging requires coordinated support across the vehicle and charging hardware, along with compatible software and a contract provider. Not every vehicle with a CCS (Combined Charging System) connector is compatible. The car must support the relevant ISO 15118 implementation, run suitable software and hold a certificate linked to a valid charging contract. The charging operator and mobility-service provider must also be able to validate it. A provider’s app or the vehicle’s infotainment system may handle certificate installation and contract management.
Which Brands Support Plug & Charge?
Automatic authentication is gaining ground. Tesla’s Supercharger network offers Tesla drivers a plug-in-and-charge experience, but its proprietary authentication is technically distinct from ISO 15118 Plug & Charge. Mercedes-Benz has integrated Plug & Charge into its Charging Hubs and affiliated services. Volkswagen, Cupra, Porsche and BMW have introduced compatibility through their own charging platforms and software updates.
Availability still depends on the specific charger, vehicle and operator. Ionity, for example, offers Plug & Charge at select locations in Spain, though not every contract or vehicle is supported at every site. Tesla also identifies some Supercharger locations as open to non-Tesla vehicles with CCS compatibility. Access depends on the location’s policy and the driver’s authentication or payment arrangement. CCS compatibility alone does not guarantee ISO 15118 Plug & Charge or an app-free session.
Drivers should check compatibility by model, model year, software version, charging contract and provider before relying on the feature. The connector is only one part of the chain: the car and charger must work with the certificate infrastructure and contract-management systems.
Activating Plug & Charge
Setting up Plug & Charge is usually straightforward. Owners should first confirm their vehicle’s compatibility, typically listed in the manual, charging menu or provider’s website. They then activate a contract with a compatible provider and link it to the vehicle, often using the vehicle identification number (VIN). The associated digital certificate may be installed through the provider’s app or directly through the car’s multimedia system. Once the vehicle and charging service are configured, the certificate enables automatic authentication at supported chargers.
The ISO 15118 family also covers more than session authorization. Published in 2022, ISO 15118-20 adds support for bidirectional power-transfer use cases such as vehicle-to-grid and vehicle-to-home. Those capabilities require compatible vehicles, charging equipment and software. Support for the standard alone does not mean a specific car can send energy back to a home or the grid.
As the EV market matures, more brands are expected to adopt Plug & Charge, broadening its availability. For drivers considering a new electric vehicle, the feature can make a impressive difference to everyday convenience and security.

Basic Facts and Context
Plug & Charge is based on the DIN EN ISO 15118 standard, which governs communication between a vehicle and charging infrastructure. In the European Union, Commission Delegated Regulation (EU) 2025/656 sets requirements for specified newly installed or renovated charging points within its scope. The timetable includes requirements applying from 8 January 2026 and a later requirement for EN ISO 15118-20:2022 from 1 January 2027. Applicable provisions vary based on factors such as whether infrastructure is publicly accessible and the charging mode. For public points offering automatic authentication and authorization, requirements include EN ISO 15118-2:2016 and EN ISO 15118-20:2022.
The regulatory timeline does not make Plug & Charge automatic at every charger. The station must implement the relevant communications technology, and its operator must connect that system to certificate validation and contract management. Tesla’s proprietary system can deliver a comparable experience without being identical to ISO 15118. As infrastructure and software evolve, Plug & Charge is poised to become a standard expectation for EV owners in Spain and beyond.
