In short: The mandatory data attributes required by the EU Battery Regulation for the battery passport include information on the characteristics and performance of batteries. These data attributes are essential for tracking, managing and ensuring the sustainability of batteries throughout their life cycle. Some of the mandatory data attributes can be:
1. unique identifiers for each battery to track its origin and use.
2. information about the battery’s energy capacity and voltage
3. information on the materials and chemicals used in the battery
4. date of manufacture to determine the age of the battery
5. guidelines for proper disposal and recycling of the battery at the end of its life.
Currently (as of mid 2024), there are over 100 individual values and details that must be recorded for each battery and stored in the battery passport. This includes both static information (e.g. date of manufacture) and dynamic values (such as the state of health of a battery), which must be updated regularly during the life cycle of the battery. However, not all information is mandatory for every battery type.
These mandatory data attributes contribute differently to the value of the battery passport:
- Transparency: providing stakeholders with detailed information on battery composition, performance and end-of-life.
- Traceability: Enabling batteries to be traced throughout the supply chain, from manufacture to disposal, to ensure compliance with regulations and sustainability standards.
- Improving decision making: Enabling informed decisions regarding the sourcing, use and end-of-life management of batteries based on accurate and comprehensive data.
- Circular economy: Promoting the reuse, recycling and recovery of materials from batteries, thereby reducing waste and environmental impact.
