The European Commission has published a document on battery data sharing, aligned with the new rules of the revised Renewable Energy Directive. The document aims to support EU Member States in implementing Article 20a, paragraph 3 of the Directive.
What is the purpose of the new rules?
The new requirements aim to ensure greater transparency and support the energy transition. They call for free real-time sharing of data from electric vehicle batteries with users and authorized third parties. This includes information such as:
-
state of charge;
-
health of the battery;
-
location of the vehicle.
The goal is for all EU countries to adopt a common approach to these requirements.
Why is data sharing important?
The main goal is to increase transparency and enable smarter use of batteries. This will support:
-
smart and bidirectional charging,
-
better integration with energy systems.
Access to the data should be provided wirelessly (Over-the-Air) via existing charging points or, when the vehicle is plugged in, through a cable or Wi-Fi connection.
What are the benefits for users?
The system will enable the creation of new services beneficial to electric vehicle owners, such as:
-
apps for smarter driving,
-
improved trip planning,
-
optimized charging,
-
more precise battery performance monitoring.
Context and next steps
This document builds on a series of guidelines and recommendations published by the European Commission in September 2024 and July 2025. These are part of the broader efforts to implement the revised Renewable Energy Directive.
