Customer ServiceThese different modeling approaches can forecast the whole life in terms of battery capacity fade and/or IR growth ( ). However, the model performance heavily relies on the quality and quantity of the investigated dataset and the selection of the modeling methodology.
However, the extraction steps of health indicators (HIs) limit the feasibility and applicability of data-driven methods. This study proposes a novel estimation framework using deep residual shrinkage network (DRSN) and uncertainty evaluation to estimate the lithium-ion battery capacity directly; model inputs are only random fragment charging data.
The observable ageing effects originate from various chemical and physical mechanisms from the molecular to the macroscopic level. 7, 9, 28 These mechanisms, subsequently called ageing mechanisms, depend on the operating conditions to which the battery is exposed.
Figure 6 displays the simulated battery life against the measured capacity fade, which is also found to be related to the IR growth. The number of performed WLTC cycles is adjusted with a factor of 1.3 as an 80% operating window is considered for dynamic cycling, while the model is based on full equivalent DoD cycling.
On the contrary, battery physics-based models can identify the loss of lithium inventory and active materials by analyzing the key degradation mechanisms such as solid-electrolyte interphase, lithium plating, etc. ( ).
While in use, a battery undergoes plenty of charge-discharge cycles from shallow to full depth along with several other operating conditions, which result either in capacity fade and/or internal resistance (IR) growth.
