The Range of an EV Vehicle Despite the relatively high willingness of consumers to consider an EV, many seem not willing to compromise in key criteria, such as range. While on average 80 percent of drivers surveyed typically drive less than 80 kilometers per day, consumers expect EVs to travel considerably farther. The U.S. and France seemed to have the highest sensitivity toward range, with only 63 percent and 67 percent, respectively, satisfied with a range of 480 kilometers. India, Taiwan and Brazil, however, seemed to have more realistic expectations, with nearly half of their populations satisfied with a range of up to 160 kilometers. In each country, the majority of drivers expect ranges much longer than their typical weekday driving distances and correlate much closer to ranges provided in conventional internal combustion engine (ICE) vehicles. In all regions, expectations far outpaced reality, typically by a factor of two to three times. The reality: Current technology permits most electric vehicles to cover an average of only 160 kilometers between charges. The main limiting factor for range is energy density. Energy density represents how much electrical energy the battery can store per unit mass. In recent years, lithium ion batteries (LiBs) have offered the highest energy density and power relative to their size and have a relatively long life cycle. Looking at automobiles already introduced and announced product introductions around the world through 2019, for most manufacturers, the driving range of their pure EVs still falls short of consumer expectations. In fact, there is little or no increase in range beyond 160 kilometers over this time horizon based on announced vehicle introductions from most manufacturers. But, manufacturers are working on the issue and expect energy density to improve over the remainder of the decade, reaching 200–250 Wh/kgii by 2022 assuming government targets are hit. This will serve as one solution to help increase the overall driving range but assuming the battery size (i.e., mass) remains around the 150 kg weight that is commonly used today, it still equates to a driving range well short of current consumer expectations. Manufacturers will likely turn to the battery mass and operating efficiency (kilometers per kilowatt hour of energy), in addition to energy density, and vehicle weight reductions combined with advanced high-strength, light weight material compositions in order to increase driving ranges.
