Despite rapid development of automotive batteries the cycle life is still an issue, especially when fast-charging is used. This is especially the case for large-format energy-optimised cells developed for EVs and heavy-duty PHEVs. The aim of this project is to: a) Quantify and characterise Li-ion battery ageing as a function of load conditions, cell design and cell chemistry. b) Develop ageing models for the most important ageing mechanisms and incorporate these into physical first-principles models for large-format energy-optimised cells c) Identify suitable battery types and establish recommendations for cycle life optimisation while fast-charging The project is a formed by a broad cooperation between all parties within the Swedish Hybrid Vehicle Center Theme 3 to ensure high technical and scientific level. Three post-doc’s and research efforts by senior researchers from industry is included as well as cycle life testing and cooperation with other national R&D projects.
