Cover Story: Commercial electric vehicles (EVs) continue to push the boundaries of lithium-ion battery chemistry, with new EVs consistently achieving 200+ miles of range according to the United States Environmental Protection Agency (EPA). However, this range is measured under ideal conditions. To provide a realistic understanding of EV range, a model was developed that considers tire pressure, vehicle mass, road grade, wind, vehicle speed, pack ageing, rain, snow, and cabin conditioning. Calibration of seven commercial EV models to EPA city and highway tests found an average deviation of less than one mile. Subsequent modeling within the Kansas highway system found losses up to 57.8% and 37.5% in range at 20 °F and 95 °F, respectively, which could exacerbate consumer range anxiety. Findings suggest that the EPA should reconsider their testing procedure. View this paper
