Do all batteries need to be CE marked?

Some requirements are only applicable for some battery categories. Requirements associated with a new CE conformity assessment of batteries are introduced in the Regulation. This means that all batteries, regardless of whether they are used in a product or supplied separately, need to be CE marked according to this regulation.

When does the battery regulation come into effect?

The regulation started to apply on 18 February 2024. Until 18 August 2025, the regulation will coexist with the Battery Directive (2006/66/EC). But from 18 August 2025, the regulation will be the main EU legislation for batteries since the Battery Directive is repelled to a great extent at that date.

How does temperature affect battery performance?

With an increase in temperature, the batteries exhibit improved power outputs and higher capacities due to fast ion migration in both the electrolyte and electrode materials, and rapid electrochemical reactions. However, side reactions become more violent, resulting in fast capacity fade and provoking higher temperatures .

What is the target temperature of a battery?

The target temperature (T tgt) of heating is often different, such as 60 °C , 29.1 °C , 10 °C , and 5.6 °C , which is determined by the performance of the battery , .

When will the CE-marking requirements for portable batteries start to apply?

The CE conformity assessment and CE marking requirements started to apply on 18 August 2024. Initially, requirements for carbon footprint, recycled content and performance and durability requirements for portable batteries of general use will not be part of the CE-marking but will be added at a later date.

Why is temperature uniformity important for battery thermal management?

Also, temperature uniformity is crucial for efficient and safe battery thermal management. Temperature variations can lead to performance issues, reduced lifespan, and even safety risks such as thermal runaway. Uniformity in temperatures within battery thermal management systems is crucial for several reasons: 1.
