Digital battery passport

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.
