Joachim Schaeffer received the MIT Open Data Price for a large lithium-ion battery field dataset, which includes 133 million rows of data from 28 battery systems provided by an industrial cooperation partner. Openly available data sets in the field of batteries are still limited. The data-set is the first openly available dataset of batteries that failed in the field. It enables further research into battery health monitoring and fault detection, as well as modeling, which is important for battery safety.

The achievement is made possible through a close cooperation between the Control and Cyber-Physical Systems Laboratory of Rolf Findeisen at TU Darmstadt and the Group of Richard D. Braatz at MIT as well as through the contributions by an industrial partner.

The data-set, as well as machine learning approaches for monitoring and fault analysis based on Gaussian processes will appear in an accommodating article, that is available as pre-print. The open-data set is available under Lithium-Ion Battery System Field Data
