11:20The Role of Recycling in a Raw Materials Supply Chain for the Battery Industry

Recycling of spent batteries is one of the most important activities to support and to secure the raw materials supply for battery productions. There has been a significant development in the recycling technologies in recent years and more will come. The change is affected by the need for raw materials and will be heavily influenced by new battery directives in EU.

• Current challenges in the recycling/supply of raw materials
• The most critical steps in a whole value chain
• New battery directive and its real implementation

The Role of Recycling in a Raw Materials Supply Chain for the Battery Industry

• How can we make sure all batteries are recycled at end of life? When there is only profit in recycling the most valuable metals like Ni and Co, howe can we ensure that instead, all of the materials are recycled?
• Can we design the batteries to make them easier to separate in the recycling process? Today, the materials in a battery are tightly stuck to each other.
• The future batteries we produce will not use exactly the same materials as the 10-20 year old ones we recycle. How do we handle that?

13:30Potential Goal Conflicts and Trade-Offs in New Battery and EV Regulations

The market demand for electric vehicles (EV) and the associated traction batteries is growing exponentially and is expected to continue to increase for decades. Geopolitical concerns related to availability critical raw materials as well as the urgency transition from linear to circular value streams for sustainability are driving forces for regulatory development in the EU and globally. However, the circular value chain implies potential goal conflicts, for example:

• Useable lifetime of manufactured batteries, incl extending this by remanufacturing and repurposing vs. availability of recovered critical materials from recycling for production of new batteries
• Flexibility of production and recycling processes to enable technology innovation and new cell chemistries vs. high yields and quality of recyclates
• Optimization of EV battery designs, safety, performance and durability vs. circularity interests of simplicity and common engineering solutions

Trade-offs will be needed as not all targets can be met simultaneously while the market demand continues to increase and the technology area is evolving rapidly.

14:10Development of High Voltage Batteries for Commercial Applications

The electrification for commercial vehicles is undergoing a steep rise in the world. Starting with buses, city distribution and waste management some years ago now also the large volume haulage applications are being electrified along with construction equipment, marine applications etc. This talk will address the opportunities and challenges of electrification of the wide variety commercial applications of the Volvo Group.

• Commercial vehicle batteries of the Volvo Group
• Flexibility needs and battery usage
• Battery size, technology, vehicle range need and charging

15:40Exploring New Battery Chemistries for Sustainable EVs at Polestar

Polestar is looking into next-generation batteries, emphasizing the sustainable aspect of both Li-ion and post-Li battery technologies. This presentation will show some examples of our experimental and theoretical research activities on future cell chemistries.

• How can sustainable EVs with zero carbon footprint be achieved?
• How can the cell chemistry be tuned towards low environmental impact while maintaining high performance?
• How can theoretical models be used to predict the lifetime and performance of the battery pack by looking into underlying electrochemical reactions inside the cell?
• Are Na-based batteries a realistic sustainable alternative for future EVs?

16:10More Efficient and Health Conscious Usage of Lithium Ion Batteries by Adaptive Modeling

An optimal management of batteries is dependent on a known behaviour of the cells, i.e., accurate cell models. The behaviour, however, depends on the individual cell, the operating conditions and also on the ageing of the cells, such that accuracy cannot be maintained by a fixed model. Model adaptation means achieving models that adjust according to online recorded measurements, aiming for accuracy at all times and for all conditions and, hence, providing prerequisites for an optimal management.

• The role of adaption in battery management
• Prediction and estimation using classical methods and machine learning
• Ageing adaptive physics based modelling: Status today and future challenges

16:40Preparing for an Electric Future: Battery Management System Development at Volvo Cars

The battery management system (BMS) is an important enabler in Volvo Cars transformation to a fully electric premium car company. The BMS shall provide optimal, reliable, and safe operation of the battery, and impacts several vehicle-level attributes, such as, charging time, energy efficiency, drivability, cost, and sustainability. We understood the importance of the BMS early and have worked strategically for over 10 years to move BMS development in-house.This presentation will cover where we are today and some challenges we foresee for the future

• Why battery management is important for electric vehicles
• BMS development at Volvo Cars
• Where is the battery management field going?
