European Battery Regulations Paving the Way for a Sustainable Future

The EU Battery Regulation promotes sustainable battery production, use, and disposal, enhancing transparency and competition, and reducing the carbon footprint, setting an example for others.

FREMONT, CA: Circular and green economy have become popular terms across various industries, including the battery and accumulator sectors. To ensure a sustainable value chain, there have been ongoing discussions about implementing comprehensive and updated European regulations specifically for this sector.

In European countries, the placement in the market of batteries and accumulators, including their collection and end-of-life recycling, is currently regulated by Directive 2006/66/EC. According to this directive, Member States must implement every necessary measure to promote and optimise separate collection, preventing these products from being disposed of as mixed municipal waste.

As a result of this, the establishment of collection points in proximity to users was initiated, which enabled them to easily and at no cost, hand over their used batteries and accumulators to manufacturers for collection.

Nevertheless, different types of batteries irrespective of their chemistry and application have become outdated due to the rapid growth of electric vehicles that use advanced and complex batteries. It is no longer suitable for regulating the recycling and disposal of modern-day accumulators since it has not kept up with the latest technological advancements.

Thus, there is a need to replace the existing directive with a new regulation that is better suited to the increasing demand for batteries and aligns more closely with the EC's goals of achieving climate neutrality.

Agreement Towards the  New European  Battery Regulation

The European Union has set a significant new goal for the future: to enhance the circular economy, promote sustainable products and processes, and support technological advancement in the battery industry. To achieve this goal, the EU has introduced a new regulation, the EU Battery Regulation, which provides a clear direction for a sustainable regulatory framework for batteries in Europe. This regulation will gradually replace Directive 2006/66/EC starting May 2023 and will be implemented in all member countries simultaneously. The primary objective of this regulation is to minimise the detrimental effects of batteries on the environment.

What are the Main Requirements Batteries Must Meet?

The new European Battery Regulation has established several general provisions to regulate the battery value chain in Europe and reduce its environmental impact. These provisions cover various aspects, from technical documentation on the battery to a detailed Environmental Footprint declaration for accumulators, to the battery recycling policy. The aim is to ensure entire battery value chain is environmentally sustainable and well-regulated.

The European Battery Passport

Starting from May 2026, batteries with a capacity of more than 2kWh sold in the European market must be electronically registered. This registration will take the form of a Battery Passport, which will feature a QR code for identification and a CE label to demonstrate compliance with the safety and traceability standards outlined in the new European Battery Regulation.

The Battery Passport is a digital record that facilitates communication between manufacturers, end-users, and recycling operators. It contains information on the carbon footprint of the battery manufacturing process and ensures that batteries can be traced throughout their lifecycle. The Battery Passport aims to enhance transparency and communication across the battery value chain.

QR Code on each Battery

To make it easy for consumers, economic operators, and other stakeholders to access the information and traceability requirements in the Battery Passport, a QR code will be provided. This QR code must be printed or engraved visibly, big enough to be read by commonly available QR code readers, and indelible on each battery.

CE Label on the Batteries

Starting from May 2026, all types of batteries sold in the European market must bear the CE mark in addition to the Battery Passport. The CE mark is issued by a notified certification body and signifies that the product complies with EU safety, health, and environmental protection standards. The mark must be visible, legible, and permanent on the battery, and if this is not possible, it can be placed on the packaging and accompanying documents, along with the QR code.

Furthermore, the CE marking on the battery must include the identification number of the certifying body. If necessary, the marking must also be accompanied by hazard pictograms or other warning labels related to battery use, storage, transport, and disposal.

BMS: The Battery’s Health Indicator

To allow the Battery Passport to obtain up-to-date information on the health of batteries and their expected lifespan, the new European Battery Regulation requires all batteries to be equipped with a Battery Management System (BMS) from May 2024 onwards. In addition to balancing the cells, which extends the battery's life, a BMS can estimate the battery's State of Charge (SOC) and State of Health (SOH) using voltage and current readings.

According to the European Battery Regulation, the information provided by the Battery Management System (BMS) must be accessible to the buyer or third parties. However, it is important to define which BMS data can be shared to avoid safety risks, infringement of intellectual property rights, and fraud.

Manufacturers who have already implemented management systems for their batteries will have an advantage during this transition since they are already compliant with the European Battery Regulation due to their existing technology.

Carbon Footprint: The Battery’s Environmental Impact

The EU Battery Regulation has established guidelines for quantifying the Carbon Footprint of batteries, which is the measure of total greenhouse gas emissions produced during the battery's life cycle. This analysis helps identify areas for improvement in reducing the carbon footprint.

Carbon footprint analysis is an essential component of the EU Battery Regulation and is vital for the development of a circular economy as it considers the entire life cycle of the battery. This approach is in line with the new European environmental strategy, which is different from traditional methods that only focus on manufacturing processes.

European Battery Regulation is a significant step towards a sustainable future. It addresses the environmental impacts of batteries and promotes a circular economy by setting standards for their production, use, and disposal. The regulation promotes safer and more sustainable battery technologies, enhances transparency and access to information, and supports innovation and competition in the battery market. Through the regulation's focus on carbon footprint analysis, it ensures that batteries' entire life cycle is considered, contributing to reducing greenhouse gas emissions. With the regulation in place, the European Union is leading the way in the sustainable development of the battery industry.
