A digital battery passport is an electronic document containing comprehensive information about a battery. It is designed to improve the transparency, traceability, and sustainability of batteries and is particularly relevant for electric car and e-bike batteries.
Contents of a digital battery passport
A battery passport contains, among other things:
- Technical data: capacity, cell chemistry, manufacturer, production date
- Origin of materials: Where do raw materials such as lithium, cobalt, and nickel come from?
- CO₂ footprint: Environmental impact of the battery over its entire life cycle
- Usage and charging history: battery condition, previous charging cycles
- Recycling and disposal information
Objectives of the Battery Passport
- Better recyclability through clear material information
- More sustainability through supply chain documentation
- Increased safety through accurate battery history
- Facilitated reuse (second-life concepts for batteries)
Legal basis
The EU Battery Regulation stipulates that from 2027, large industrial batteries and batteries for electric vehicles will require a digital battery passport.
Relevance for e-bikes
E-bike batteries could also benefit from a digital passport, as it makes used batteries more secure to trade, prevents fraud and improves recycling.
In short: The digital battery passport is a decisive step towards a sustainable and transparent battery industry.
