New EU Battery Regulation: Focus on Sustainability, Performance, and Precise Measurement Technology

The new EU Battery Regulation (EU) 2023/1542 has been in effect since July 17, 2023.
Its goal is to significantly enhance the sustainability, safety, and performance of batteries in Europe – a key pillar in the implementation of the European Green Deal.

The regulation sets comprehensive requirements for the production, use, and recycling of batteries. Manufacturers – especially those producing industrial and traction batteries (e.g., for electric vehicles) – are now obligated to provide detailed evidence of electrochemical performance and durability. Annex IV defines mandatory measurement parameters such as rated capacity, capacity and power fade, internal resistance, and its percentage increase.

Precise Measurement Using EIS Technology

Electrochemical Impedance Spectroscopy (EIS) plays a central role in this context. This advanced analysis method evaluates the frequency-dependent internal resistance of a battery under real operating conditions and breaks it down into:

• Ohmic components (resistances from electrolytes and conductors)
• Capacitive components (double-layer capacitance and charge storage in active materials)
• Inductive components (internal connections and conductor paths)

The EU regulation indirectly demands high-quality measurement methods – a clear indicator of the need for state-of-the-art diagnostic technology.

SIVONIC EIS Meter for Regulation-Compliant Battery Diagnostics

With the SIVONIC EIS Meter, a powerful solution is available that enables the accurate measurement of all parameters required by the regulation – especially for traction batteries in electric vehicles. In doing so, we actively contribute to achieving Europe’s sustainability goals and driving the development of efficient energy storage systems.
