Annex VIII requires technical documentation that lets assessors and authorities evaluate conformity. For all modules, the record should cover the applicable requirements and the battery's design, manufacture and operation, with a risk analysis, intended use, design and manufacturing drawings, label specimen, applied harmonised standards or common specifications, alternative technical solutions where standards are not used, design calculations, examinations, documentary evidence and test reports.
For Module D1 and Module G files linked to carbon footprint or recycled-content requirements, include the supporting studies, calculations, input-data evidence and methodology references required for Articles 7 and 8. The EU declaration of conformity must follow the Annex IX model structure, identify the battery model or battery, state the Union acts and specifications used, and stay up to date in the required market language.
