Cycling degradation in lithium-ion batteries refers to the progressive deterioration in performance that occurs as the battery undergoes repeated charge and discharge cycles during its operational life . With each cycle, various physical and chemical processes contribute to the gradual degradation of the battery components .
Degradation rates emerging from the two battery degradation models are compared across two climatic conditions. The reduction in these rates when one of two derating strategies are implemented is then calculated and compared to the case with no derating. 4.1.
In a −20 °C environment, with a discharge rate of 0.33~0.50 C, the larger the rate, the slower the relative capacity degradation. This phenomenon may be due to enhanced battery activity from internal heat generation when charging at a low rate.
Over time, the gradual loss of capacity in batteries reduces the system’s ability to store and deliver the expected amount of energy. This capacity loss, coupled with increased internal resistance and voltage fade, leads to decreased energy density and efficiency.
This increase in resistance is frequently the result of the battery aging and degrading, a process that is sped up by frequent cycles of charge and discharge. Battery degradation also affects EV batteries.
In this research, we propose a data-driven, feature-based machine learning model that predicts the entire capacity fade and internal resistance curves using only the voltage response from constant current discharge (fully ignoring the charge phase) over the first 50 cycles of battery use data.
