Portable batteries of general use. First stakeholder consultation meeting and analysis on survey results

Abstract

As part of its continued support to DG ENV in the context of the new Regulation on sustainable batteries, the Joint Research Centre, Energy Storage Unit (JRC.C.1) has organized the first stakeholder consultation on portable batteries of general use with regard to performance and durability requirements. The meeting, which took place online on the 14th of June 2022 was followed by an online survey shared with the participants at the workshop. This report summarizes the results of the online survey and the discussions that took place during the workshop itself. While the standards use different parameters for characterizing the performance of primary and secondary portable batteries of general use, the draft Regulation foresees the same parameters for both types of battery. Stakeholders agree that this should be changed; e.g. discharge performance for primary batteries should be measured by Minimum Average Duration (MAD) for different application tests and by capacity for secondary batteries (1 ). Opinions on how the different application tests for primary batteries should be combined to obtain a single pass/fail criterion differ. It will require further work to decide on the approach.
