Due to the push of powertrain electrification for road transport decarbonisation purposes, an increase in demand for respective traction batteries is projected in the upcoming years.
By today’s measures the battery contributes a large part to the CO2 emissions of the vehicle in the life-cycle. A consequent monitoring and reduction of these CO2 outputs are necessary. The regulations around the battery passport have the potential to be the right framework for an open discussion about the CO2 caused as well as the future reduction. The passport idea is currently gaining momentum (again) due to policymaker push by the European Commission; cf. Green Deal, CE action plan, but as well as the proposal for a new directive on batteries and waste batteries.
This lecture will elaborate the latest status of the battery passport discussions. Furthermore it will show the possible directions for a digital product passport concept and solution. It provides a conceptual information model of a digital battery passport for an electric vehicle traction batteries in the context of sustainable circular product management with focus on (dynamic) LCA. The lecture will answer questions on how digital twin methodology apply, data driven methods for e.g. battery aging are used and how they can be ideally implemented in the real-life production process.
Finally it will show the possibilities for CO2 reduction in the battery life-cycle from exchanging raw-materials, alternative production methods throughout efficient charging and second life options and finally sustainable engineering and design-to-CO2.
