Fig. 2: Overview about the battery performance degradation in the MIT dataset4.
From: Early prediction of lithium-ion battery degradation with a generative pre-trained transformer
Each curve represents a different charging cycle. The blue curves show that the battery charging capacities are close to its initial capacities. In contrast, the red curves indicate that the battery charging capacities are only 80% of the factory capacities, corresponding to a state-of-health (SOH) of 80%, suggesting that the battery performance has significantly deterioration and reaches to the end of its lifetime. a is the subset of training data. b is the subset of testing data. Source data are provided as a Source Data file.
