The Optimization of an Electric Vehicle (EV) for Improved Range
No TL;DR found
Abstract
The study is a focus on possible factors affecting an electric vehicle (EV) in “real world” testing. Factors such as wind, temperature, and humidity were considered in testing range. A base model 2017 Nissan Leaf EV was modified to remove weight through altering wheel rims and car seats. Removing weight from a vehicle has been used in car racing for many years to increase vehicle speed. Through past studies focusing on new Teslas (EV), wheel rim structure has been found to increase range. Increasing the EV range through the removal of weight was thought to be possible. In addition, the Nissan Leaf was recharged while hot air was pumped underneath (for one hour from a clothes dryer) to increase battery capacity thereby adding extra kilometers to the range. There was an increase in range through recharging after the trial ended that day, it was aided by the hot air. A minimal gain in range was found after the third set of trials where weight was removed. Future research should look at pumping hot air underneath the EV (for multiple hours) while recharging during cold weather (under 0 C/32 F) to find a solution for reduced range during colder months.
