Predicting Battery Lifetime Under Varying Usage Conditions from Early Aging Data

no code implementations17 Jul 2023 Tingkai Li, ZiHao Zhou, Adam Thelen, David Howey, Chao Hu

Using a newly generated dataset from 225 nickel-manganese-cobalt/graphite Li-ion cells aged under a wide range of conditions, we demonstrate a lifetime prediction of in-distribution cells with 15. 1% mean absolute percentage error using no more than the first 15% of data, for most cells.

Federated Learning with Uncertainty-Based Client Clustering for Fleet-Wide Fault Diagnosis

1 code implementation26 Apr 2023 Hao Lu, Adam Thelen, Olga Fink, Chao Hu, Simon Laflamme

To quantify dataset similarity between clients without explicitly sharing data, each client sets aside a local test dataset and evaluates the other clients' model prediction accuracy and uncertainty on this test dataset.
