State-of-health estimation of Li-ion batteries in the early phases of qualification tests: An interpretable machine learning approach

作者:

Highlights:

• Developing machine learning models for the SOH estimation of Li-ion batteries.

• Extracting three types of statistical features from capacity fade data.

• Interpreting the model’s behaviors and predictions based on SHAP.

• Reducing the time required for qualification tests to 100 cycles.
