In recent years, the promising avenue of ML techniques and data-driven methodologies has emerged as a compelling approach for predicting battery degradation and estimating SOC, SOH, and RUL [19, 20].While simple ML models have been deployed for this purpose, they come with certain limitations, as a batteries degradation is complex and non-linear in nature .
Analysis of battery models is an area of interest in recent research.

The exploitation of industry datasets covering a wide spectrum of cycling conditions can inform on real-use battery cell degradation. To investigate LiB cell degradation rate, we need to control a number of cycling conditions and protocols which directly impact in an uneven manner the battery cell lifespan .

The main contributions of this paper are as follows: (1) A novel automatic SOH extraction algorithm for offline charging data of road vehicles is proposed to label the battery SOH degradation data.
The model-based method requires an equivalent circuit model (ECM) to describe the battery behaviors which contains several model parameters , .The parameters like capacity and R int which can describe the SOH of the battery is contained in such models. Liaw et al. propose a first-order ECM to simulate the charging and discharging behavior. .
Battery modelling is used for gathering information on how the cells and bat-tery packs will behave without testing on actual batteries, though the models need to be accurate to provide dependable simulations. 1.2 Objective The main purpose of the thesis is to investigate what factors influence lithium-ion battery degradation and to which extent.

The analysis of battery degradation due to V2G operation estimates the value loss of the battery and BEV. Through this analysis, we calculate the compensation to break even the loss that may be incurred by the BEV user through V2G.

Since one of the effects of lithium-ion battery degradation is a loss of battery capacity and hence a decrease in the vehicle''s achievable range (Barré et al., 2013), and since such autonomy declines have been reported in actual freight BEV deployments (Taefi et al., 2016), long term operational flexibility can be preserved by taking steps

To analyze the capacity degradation process, batteries need to be cycled in various working conditions, in which a CC discharging process or a CC charging process is conducted to obtain battery discharging or charging capacity in each cycle. Fig. 2 (a) shows a typical cycling condition for battery cells tested in laboratory.
The most intuitive external characteristics of battery degradation are capacity fade and power fades [7, 8]. At present, most papers still focus on these two points to conduct battery aging investigations and modeling. It should be noted that power fade is usually more difficult to investigate, so internal resistance is often analyzed instead .
The SEI layer, formed on the electrode surfaces due to electrolyte decomposition, suggests the LLIs within the battery, leading to a reduction in its capacity and performance over time . Figure 9. LIBs degradation mechanisms based on DRT plots.

The primary degradation mechanisms of LIBs involve the loss of anode/cathode active materials and the LLI, analogous to water loss from the tank . Additionally, the loss of electrolytes, including additives, is significant, with excessive loss potentially leading to capacity decline as batteries age.
