SSEVAQWB Addressing EV Questions and Answers Latest Version Already Passed What is the main benefit of electric vehicles (EVs) over traditional gasoline vehicles? Electric vehicles produce zero tailpipe emissions, reducing air pollution and environmental impact. What is the function of an electric vehicle’s battery management system (BMS)? The BMS monitors and manages the performance of the battery, ensuring safe charging, discharging, and maintaining optimal battery health. What is regenerative braking in an electric vehicle? Regenerative braking recovers energy during braking and converts it into electricity to recharge the battery, improving efficiency. How does the charging time of an electric vehicle vary? Charging time depends on the charger type, battery capacity, and current state of charge, with faster chargers reducing the overall charging time. 2 What is the role of an inverter in an electric vehicle? An inverter converts the DC electricity from the battery into AC electricity to power the vehicle's electric motor. What is the difference between Level 1, Level 2, and DC fast charging for electric vehicles? Level 1 charging uses a standard household outlet, Level 2 charging uses a specialized home or public charger, and DC fast charging provides rapid charging at public stations. How does an electric vehicle’s motor differ from an internal combustion engine? An electric motor generates torque directly from electrical energy without the need for combustion, providing instant power and efficiency. What is the impact of temperature on an electric vehicle’s battery performance? Extreme temperatures, particularly cold weather, can reduce battery performance and range by affecting the chemical reactions inside the battery. What is the typical range of an electric vehicle on a single charge? The range varies by model, but many electric vehicles can travel between 150 to 350 miles on a single charge. 3 How do electric vehicles contribute to energy efficiency compared to traditional vehicles? Electric vehicles are more energy-efficient because they convert a higher percentage of electrical energy into motion than internal combustion engines convert fuel into motion. What is the significance of the kilowatt-hour (kWh) rating in an electric vehicle? The kWh rating indicates the battery capacity, which helps determine the driving range and energy consumption of the vehicle. What is an electric vehicle’s onboard charger? The onboard charger converts the AC electricity from the charging station into DC electricity to charge the vehicle’s battery. How do EVs impact greenhouse gas emissions compared to gasoline-powered vehicles? Electric vehicles generally have lower overall greenhouse gas emissions, especially when charged with renewable energy sources. What are the common types of electric vehicle batteries? 4 The most common types of EV batteries are lithium-ion (Li-ion) and lithium iron phosphate (LiFePO4). What are the maintenance requirements for an electric vehicle compared to a traditional vehicle? Electric vehicles require less maintenance as they have fewer moving parts, eliminating the need for oil changes and reducing brake wear due to regenerative braking.
