Another setting considers , which is a multi-class classification task grouping batteries into lifetime. Given a training dataset , the goal of modeling is to learn the nonlinear mapping from the early-cycle raw battery data to the battery lifetime group, which is expressed in (1). (1)
Classification of battery models One of the first steps of battery modeling is to decide, what is the purpose of the modeling. Every application of the model requires slightly different approaches and parameters. There is no strict rule, how to categorize battery models, same models can belong to more than one class.
Finally, an RLR model integrating battery nominal and operational parameters was developed to classify battery into different lifetime groups. Computational studies were conducted on datasets containing LIBs of three different chemistries and tested under multiple conditions.
The developed method is effective and robust to different battery types. The battery quality classification accuracy can reach 96.6% based on data of first 20 cycles. Lithium-ion batteries (LIBs) are currently the primary energy storage devices for modern electric vehicles (EVs).
Average results of 20 splits are listed in Table 8. As shown in Tables 8 and in the multi-class battery classification task, the proposed RLR model still presents the best performance. The four metrics are all higher than considered benchmarks, which are 87.6%, 70.8%, 73.4%, and 72.1%, respectively.
A deep learning method for the early classification of battery qualities is studied. A deep network model deriving latent features indicating battery qualities is developed. The developed method is effective and robust to different battery types. The battery quality classification accuracy can reach 96.6% based on data of first 20 cycles.
