Improve in-situ life prediction and classification performance by capturing both the present state and evolution rate of battery aging

no code implementations27 Aug 2023 Mingyuan Zhao, Yongzhi Zhang

And the degradation rate is captured by two features extracted from the differences between the voltage relaxation curves within a moving window (for life prediction), or the differences between the capacity vs. voltage curves at different cycles (for life classification).

Comprehensive performance comparison among different types of features in data-driven battery state of health estimation

no code implementations27 Aug 2023 Xinhong Feng, Yongzhi Zhang, Rui Xiong, Chun Wang

In this study, a physics-informed Gaussian process regression (GPR) model is developed for battery SOH estimation, with the performance being systematically compared with that of different types of features and machine learning (ML) methods.
