Lithium-ion batteries in electric vehicles (EVs) exhibit complex degradation patterns influenced by factors such as temperature gradients, pressure variations, and manufacturing inconsistencies. These spatially heterogeneous degradations, including lithium plating and capacity fade, are challenging to detect through conventional electrical measurements alone. At Scania, we are pioneering advanced post-mortem diagnostic techniques to assess these localized degradation phenomena. This presentation will delve into our latest research on developing and applying electrochemical methods, focusing on the OCP-based Local State-of-Health Assessment (OLSA) technique, to provide rapid and reliable evaluations of battery health at the microstructural level.

The audience will get an:

• Understanding the impact of spatially heterogeneous degradation on EV battery performance
• Insights into Scania’s innovative post-mortem diagnostic methodologies
• Application of the OLSA technique for detailed battery health assessments
