Core Viewpoint - The study by Geotab indicates that driving speed significantly impacts the range of electric vehicles (EVs) more than high temperatures, especially during long-distance travel [3][4][12]. Group 1: Impact of Speed on EV Range - Geotab's research shows that in the speed range of 50-80 mph (80-128 km/h), the reduction in range can be as high as 39% due to increased air resistance compared to the impact of air conditioning [8][10]. - For a vehicle with a 65 kWh battery, driving at 50 mph (80 km/h) in 86°F (30°C) conditions results in a range of 143 miles (approximately 230 km), which decreases to 88 miles (141 km) at 80 mph (128 km/h) [8][10]. - Aerodynamically efficient electric sedans experience a 28% reduction in range within the same speed range under similar temperature conditions [10]. Group 2: Physics Behind Energy Consumption - The increase in energy consumption at higher speeds is attributed to the square relationship of air resistance to speed, meaning that doubling the speed requires four times the energy to overcome wind resistance [11]. - Geotab's sustainability manager emphasizes that reducing speed by 10-15 mph (16-24 km/h) can extend the range by 20% to 30%, depending on the vehicle type [11]. Group 3: Temperature Effects on EV Range - High temperatures have a more pronounced effect on range at lower speeds, where air resistance is less significant, making the energy consumption of air conditioning more impactful [12]. - At 95°F (35°C), the average range of EVs can decrease by 17% compared to 75°F (24°C) [12]. Group 4: Practical Tips for Extending Range - Geotab suggests several methods to extend range without sacrificing comfort, such as reducing speed, pre-conditioning the vehicle while plugged in, and using air conditioning efficiently [15][16][17]. - Avoiding rapid acceleration and deceleration, parking in shaded areas, and refraining from fast charging in extreme heat can also help maintain battery performance [19][20]. Group 5: Addressing Range Anxiety - The findings aim to alleviate range anxiety among EV users by providing insights into factors affecting range and practical strategies to manage them [22].
