tool-based approach for single or multiple (hybrid) pack

The fast growth of the electrified vehicles market will translate not only into an increase of raw materials consumption, but also to an increase of waste batteries after their use in electric vehicles. Once collected, the batteries are usually recycled, producing secondary raw materials; however, their residual capacity could be used in other applications before recycling. The interest in this topic of repurposing electric vehicle batteries is high, as can be seen by numerous industrial initiatives by various types of stakeholders along the value chain of electric vehicle batteries and by policy activities that are related to waste batteries.
Sustainability Assessment of Second Life Application of Automotive Batteries (SASLAB), an exploratory project that was led by the European Commission's Joint Research Centre (JRC), aimed at assessing the sustainability of repurposing electric vehicle batteries to be used in energy storage applications from technical, environmental, and social perspectives. In this paper, a mapping of industrial demonstration and publicly-funded research projects in the area is presented, followed by an experimental assessment of the capacity and impedance change of lithium-ion cells during calendar and cycle ageing. Fresh cells and cells aged in the laboratory, as well as under real-world driving conditions, have been characterized to understand their application-specific remaining lifetime, beyond the 70% to 80% end-of-first-use criterion. For this purpose, the pre-aged cells were examined under duty-cycles that resemble those of second use grid-scale applications. The experimental investigations aimed at both, to better understand the performance of cells in second use after being dismissed from first use and provide input parameters for the environmental assessment model.

Sustainability Assessment of Second Use Applications of Automotive Batteries: Ageing of Li-Ion Battery Cells in Automotive and Grid-Scale Applications

This paper describes a tool-based approach for dimensioning single or multiple (hybrid) battery pack systems for electric vehicles. The tool comprises a sophisticated vehicle and battery model as well as an optimization frame-work. Applying the hybrid battery approach to different vehicle types showed advantages in weight, volume, and costs, which are explained and discussed in this paper.
