The article investigates the shift to electric cars and how they can achieve zero emissions. It explores aspects like electric car range, battery efficiency, and energy consumption. The study simulates how an electric car's range varies with temperature and battery capacity. It also looks at charging times based on the charger's power and the battery's charge status. Comparisons show that electric vehicles use less energy per distance traveled compared to gasoline cars. Additionally, the study delves into how much energy is needed to power an electric car for a set distance and how quickly energy can be replenished. Overall, the research sheds light on the practicalities and energy efficiency of electric passenger vehicles.
