In 2026, the batteries of electric vehicles will benefit from a passport system

The European Union intends to establish a passport system for batteries in electric cars with the aim of knowing the history of these essential components of zero-emission vehicles.

Recently, reports have emerged that regulations regarding batteries for electric cars are going to be tightened. It was already known that a passport would be required for these batteries, and now we know a little more about it.

It is announced that 120 companies will come together to create these famous passports, the majority of which will be car manufacturers. This alliance will include companies such as BMW, Ford, General Motors, Honda, Mazda, Nissan, as well as Stellantis.

This passport will trace the full history of a battery, which car owners will have access to. The use of blockchain technology will be employed to protect data associated with cars. Moreover, the battery status will also be available in real time.

A comprehensive digital record will be created that will trace the complete history of each battery, including information such as supply chain and origin of materials. The percentage of recycled components as well as the amount of CO2 emitted during their manufacture will also be included.

This system, coveted in particular by the United States, is developed in collaboration with Amazon Web Services and Hitachi. The consortium of 120 companies, known as the Mobility Open Blockchain Initiative (MOBI), aims to increase the share of recycled materials.

Indeed, the increase in sales of electric cars has an impact on the global demand for lithium. In 2022, electric cars represented 60% of this demand, compared to only 15% in 2017.

The introduction of this "passport" will make it possible to highlight the reduction in this demand. The data stored in the blockchain will be accessible to the entire consortium.

The MOBI group is seeking to have its system adopted on a global scale, which promises to be difficult. Indeed, another consortium named Catena-X is currently working on a similar system. This consortium includes Volkswagen and Siemens among its members, and shares the same objectives as MOBI.
