 This research paper examines the relationships between performance and technical parameters in electric vehicles. It found that the weight of the vehicle had a strong correlation with the energy capacity of the battery minus 0.687 while the autonomy was positively correlated with the vehicle weight minus 0.355. Additionally, the authors concluded that the design and construction of electric vehicles should take into account both performance and technical parameters such as the weight of the vehicle and the energy capacity of the battery.
