EV Battery Production

Revolutionizing EV Battery Manufacturing with Digital Battery Passport

At Rockwell Automation, we're committed to driving innovation in the EV battery manufacturing industry. 

Our latest initiative is a collaboration with Circulor, a leader in Digital Battery Passport technology. Together, we are combining Circulor’s Digital Battery Passport technology with Rockwell Automation's MES software and professional services expertise. This approach enhances transparency, sustainability, and efficiency in battery production. It aligns with global regulatory requirements and supports the industry's move towards responsible and circular practices. 

What is a Digital Battery Passport? It is an electronic record detailing the raw materials, components, and recycled content of an EV battery. This record can be submitted to EU regulatory authorities, customs, and customers, ensuring compliance with sustainability, recycling, and carbon footprint standards. The EU Battery Regulation mandates that by February 2027, all batteries entering the European market must have a digital battery passport. This regulation ensures sustainable, responsible, and circular sourcing, driving Europe towards a more sustainable and secure battery economy. It also sets a global benchmark for consumer transparency.  

Our Digital Battery Passport solutions set new standards for transparency, sustainability, and efficiency in battery production. These solutions not only comply with global regulatory requirements but also promote responsible and circular practices within the industry. 

In collaboration with Circulor, we help customers meet regulatory requirements, including embedded carbon footprint, responsible sourcing, recycled content, and state of health performance. 

Stay ahead of the curve with Rockwell Automation's innovative solutions and discover how our collaboration can help you meet your sustainability goals and regulatory obligations.

How are EV Batteries Made?

EV batteries are made through a multi-step process that transforms raw materials into fully assembled battery packs used in electric vehicles. It begins with electrode manufacturing, where cathode and anode materials are mixed, coated onto metal foils, dried, and compressed.

Next is cell assembly, where the electrodes are stacked or wound with separators and then placed into a casing to form individual battery cells. These cells are filled with electrolyte, sealed, and undergo formation and aging, a process of charging and testing to stabilize performance.

Afterward, cells are grouped into modules, which are then integrated into larger battery packs equipped with cooling systems and battery management electronics. Throughout this process, precision, cleanliness, and quality control are crucial to ensure performance, safety, and longevity in battery production for electric cars.
