Electrification of Transportation

An initial concern of many people who consider buying an EV is the issue of charging it. There are gas stations on corners of every town and city, but where can you charge an EV? The answer to this turns out to be nearly as simple as the question of where you charge your phone: You plug it into the electrical grid when you are at home. One of the advantages of EVs is the simplicity of connecting the car to the grid to charge the battery. EVs can recharge their batteries from a basic 120-volt outlet. For most people (with daily driving of about 40 miles), overnight charging on a standard wall outlet is sufficient. For those who have longer commutes, a garage with electric vehicle supply equipment (EVSE) charging at 240 volts is also easy and convenient. When on a road trip where one needs to stop to charge the battery, more time is needed, and so it makes sense to charge the battery while at a destination or when one stops to eat or sleep. With charging at home, an EV essentially leaves the house each day with the advantage of a “full tank”. This in turn can help to alleviate “range anxiety”: The fear of running out of electrical charge in an EV. Range anxiety remains a key concern for a number of people, but it is progressively becoming less of a concern as the technological innovations of EVs have increased ranges from less than 100 miles to a number of new models having ranges of well over 200 miles for a full charge.

Range anxiety continues to be an issue to EV acceptance. Wireless power transfer (WPT) is a means to increase the range of an electric vehicle without substantial impact on the weight or cost. WPT is an innovative system for wirelessly charging the batteries in electric vehicles. There are three categories: stationary WPT: vehicle is parked, no driver is in the vehiclequasi‐dynamic WPT: vehicle stopped, driver is in the vehicledynamic WPT: vehicle is in motion.

The widespread use of EVs within large cities, EV users can plug in their cars while at work and let them charge throughout the day. This extends the commuting range and eliminates the often associated with EVs range anxiety (the fear of the batteries running out of juice in the midst of a heavy city traffic, on the highway, or in some remote location.)

However, the falling prices of battery cells and packs are perhaps the most significant driver for the future of EVs. As economies of scale and advancements in battery technology continue, the cost per kilowatt-hour is projected to decline significantly. By 2025, EV battery prices are estimated to drop below the critical threshold of US$100 per kWh, making EVs more affordable than their ICE (Internal Combustion Engine) counterparts. This price advantage, coupled with the increasing global efforts to phase out ICE vehicles and the expansion of EV fleets by automobile OEMs (Original Equipment Manufacturer), is expected to create a surge in EV demand [172–175]. Battery capacity, range, and cost are vital for widespread EV adoption. Advancements in battery technology enhance driving range, reducing range anxiety and matching traditional vehicles. Declining battery prices make EVs more accessible, speeding up the transition to sustainable transportation.
Regional allocation of EV chargers’ grid load

Second, charging in areas other than one’s neighbourhood of residence could cause individual dissatisfaction, the so-called range anxiety. Range anxiety is the fear of an EV driver being stranded with an empty-battery vehicle before researching his or her destination or a charging point (Tate, Harpster, and Savagian 2008). It is likely that multiscale allocation of charging infrastructure, in which more than half of the EV is supposed to charge in other neighbourhoods, will trigger resistance among EV drivers. To tackle this problem, multiscale allocation of EV infrastructure needs to be coupled with the development of ICT infrastructure, which informs drivers of their options and effectively reduces their level of range anxiety. A study on travel behaviour of a group of EV drivers over six months shows that drivers’ range anxiety is a subjective matter, to a substantial extent. What causes anxiety is the driver’s perception of lacking enough charge before finding an empty charger or the shortage of ‘useable range’ (Franke et al. 2012). Provision of data on accessible chargers in different neighbourhoods helps drivers to have an objective understanding of their ‘useable range’ and reduces range anxiety among them (Du and De Veciana 2013). Smartphone applications can collect data on real-time traffic, destinations and useable ranges of all EV and tailor the most energy-efficient routes for each EV driver. The applications could plan EV charging in advance and reserve a charging spot at a specific time to assure drivers of their charging opportunities at their destination (Yaqub and Cao 2012).
Learning electric vehicle driver range anxiety with an initial state of charge-oriented gradient boosting approach
Published in Journal of Intelligent Transportation Systems, 2023
The increasing ownership of EVs comes with concerns about battery safety, vehicle quality, and more importantly, driving range, or “range anxiety” (Hao et al., 2020) – fear that a vehicle does not have sufficient range, or state of charge (SOC) of the battery pack, to reach its destination and would strand its occupants. Range anxiety is one of the most significant barriers to the large-scale adoption of EVs. In addition, the charging time for an EV is significantly longer than the refueling time required for a gasoline-powered vehicle. However, despite numerous researches on the modeling of charging behaviors, modeling efforts to understand range anxiety, and specifically, at what battery percentages do EV drivers charge their vehicles, and what are the associated contributing factors, are rather limited.
