“…The EV battery degradation model utilized in the simulation framework should be not only robust but also versatile to be tuned directly through the information provided by the battery datasheet. We highlight this point because the academia offers abundant methodologies to forecast the battery capacity fade, including for instance methods based on electric circuits [28][29][30][31] or electrochemistry [32][33][34]. However, tuning such models demands a huge number of experiments, which are impossible to conduct at the economic evaluation step because we do not even have the vehicle yet.…”

The Levelized Cost of Driving (LCOD) calculates how much it costs to drive a vehicle, per kilometer, over the vehicle lifespan, and it is typically measured in USD/km. LCOD has been widely applied to assess and compare the performance of Electric Vehicles (EVs) and Internal Combustion engine Vehicles (ICVs). Unfortunately, there is no common methodology to establish how to compute LCOD. As authors use different criteria to determine which elements are relevant in LCOD, it is difficult to compare results. To overcome this issue, we re-introduce the LCOD concept, where the most relevant expenditures and incomes are included. This novel LCOD definition also incorporates key elements that are sometimes neglected, such as the second life of batteries in EVs, EV battery degradation models, and stochastic models, to characterize daily operation. The proposed methodology is applied to assess the cost of using EVs as taxis in the city of Quito, Ecuador.

“…7 These batteries have widely used electrochemical energy storage devices with most prominent technical support for automotive applications. [8][9][10][11][12][13] Recent theoretical developments in commercial lithium-ion batteries have revealed that safety and reliability still remain detracting issues for various applications. [14][15][16][17][18][19] This is because lithium-ion batteries have confined frame of stability feature in context to voltage and temperature.…”

“…[14][15][16][17][18][19] This is because lithium-ion batteries have confined frame of stability feature in context to voltage and temperature. 8 Owing to this, the battery shows non-linear behavior as its impedance value mostly depends on either potential or current of the load. This non-linear dynamic behavior of battery leads to generate instabilities during its operation.…”

Exploration of Li‐Ion Batteries during a Long‐Term Heat Endurance Test Using 3D Temporal Microcomputed Tomography Investigation

et al. 2023

High‐resolution computed tomography (micro‐CT) was used in this paper to visualize the inner structure of lithium nickel cobalt aluminum oxide 18 650 form‐factor batteries non‐destructively after and during a heat endurance test. Open circuit relaxation and electrochemical impedance spectroscopy were also conducted. We tested the different heat‐aged cells with micro‐CT and charge‐discharge and electrochemical impedance spectroscopy measurements to find the observable physical changes in the cell and connect them to the loss of performance. We found that the drastic changes in the structure of the cell at higher temperatures are well traceable. At 150 °C layer delamination and performance loss were observed, battery failure occurred with the further increase of the temperature, while at the same time, precipitation appeared and the positive temperature coefficient device fractured. Without opening the cell only tomographic methods can provide insight into the inner structure of the cell. We were able to measure the changes in the distances of the layers of the battery and decent shrinkage was observed, which can be linked to the loss of capacity and increased resistance.
