Accelerated reported battery capacity loss in 30 kWh variants of the Nissan Leaf
In a new study, 283 Nissan Leafs manufactured between 2011 and 2017 have been analyzed with respect to the battery capacity fade. The authors of the investigation conclude, that a faster rate of decline in the state-of-health (SoH) for the 30 kWh variants over the 24 kWh variants is detected. Some of the 30 kWh variants had already lost 20 % of the battery capacity after only two years of operation. Read the full paper here: https://www.preprints.org/manuscript/201803.0122/v1

Erik Schaltz received the MSc and PhD degrees in electrical engineering from the Department of Energy, Aalborg University, Aalborg, Denmark, in 2005 and 2010, respectively. From 2009 to 2012, he has been an Assistant Professor and since 2012, he has been an Associate Professor. Both positions also at the Department of Energy, Aalborg University. At the Department, he is the leader of the research group in E-mobility and Drives and the vice leader of the Batteries research group. He is a guest and associate editor in several journals related to batteries and e-mobility and he is also a board member of the Danish Battery Society. His research interests include the usage of power electronics, electric machines, fuel cells, batteries, ultracapacitors, etc. as power train in various applications like electric vehicles, industrial machinery, and heavy-duty systems. In addition, he is also focused on battery state-estimation, management (electric and thermal), and modelling (electric, thermal, and lifetime) of battery cells and packs.
