WebAug 6, 2024 · The limitation of battery size for electric vehicles has driven researchers to study driving distance. Trip patterns and traveler preferences in terms of distance are affected by multiple variables. This study, using socioeconomics, weather conditions, and vehicle characteristics as covariates, compares lognormal, log-logistic, and Weibull … WebThe traditional fragility analysis mainly contains Monte-Carlo simulation and cloud analysis methods. For Monte-Carlo simulation, the capacity is generally assumed to follow a Lognormal or Normal distribution. However, previous studies [17], [18] indicated that the Normal distribution assumption is not a strong hypothesis for developing fragility.
