Concepts and habits from gasoline refueling found to mislead EV charging

Many electric vehicle (EV) drivers carry over concepts and habits acquired from driving gasoline cars when they are charging of EVs – but the mismatch leads to time wasted, inconvenience and “range anxiety” about not finding a charger when needed, according to a new study published in the journal Energy.

The research was carried out by Professors Willett Kempton of the University of Delaware and Frances Sprei of Chalmers University in Sweden, both experts in EV technology and usage.

They interviewed EV users in both Sweden and the United States, finding unanticipated and previously unreported concepts and habits of EV charging.

Among the other findings:

If industry and consumers take advantage of these findings, that could lead to more effective charging methods, help new EV buyers adapt, and inform planning of charging stations.

Novice EV drivers, and even many of those who had months of EV experience, monitor the battery charge gauge while driving, then when the gauge is low, seek a charging station to recharge. This “monitor gauge” model is derived from driving gasoline-powered vehicles.

By contrast, the study found that a few experienced EV drivers had developed a strategy of selecting a trigger event, and using it to spur them to plug in their EV.

“Some of the more sophisticated EV users had picked a repeating event that happens at a place they can plug in and at a time or event lasting several hours. This is common when returning home at the end of the day or arriving at work," Kempton said. “A few people had selected unexpected triggers, such as shopping, and for one, when walking his dog in the evening.”

NBA stars and Achilles injuries: The road back to peak performance

A new NBA season brings plenty of storylines, from star players in new uniforms to the debut of promising rookies. But for players recovering from Achilles tendon injuries, returning to the court is just the beginning, says the University of Delaware's Karin Grävare Silbernagel. Regaining strength, explosiveness and consistent performance can take longer to achieve, said Silbernagel, a professor of physical therapy who studies tendon injuries and rehabilitation, with a focus on Achilles tendon ruptures, ankle function and long-term physical performance. Her research explores why recovery involves more than healing tissue or returning to competition. Strength, movement, tendon function and the ability to perform under the demands of sport all matter, she said. In a recent study, Silbernagel and colleagues examined single-leg jumping in people about two years after an Achilles tendon rupture. They found that fatigue affected ankle power differently on the injured and uninjured sides, highlighting how an injury can influence movement and the way the body distributes physical demands even well into recovery. Silbernagel can discuss: • Why returning to the court does not necessarily mean an NBA player has regained full strength, explosiveness or durability. • How clinicians assess recovery and readiness to return to sport after an Achilles tendon rupture. • How rehabilitation, progressive loading and return-to-sport testing can help guide recovery. • What research reveals about lingering changes in movement and function after tendon injuries. • What Achilles injuries can mean for athletic performance over time. Silbernagel leads the Delaware Tendon Research Group and consults with professional sports teams. Her research has helped inform clinical guidelines for treating tendon injuries.

Experts on Hurricane Preparedness, Public Health and Community Recovery

When hurricanes threaten communities already facing social and economic challenges, the need for effective disaster preparedness and response becomes even more critical. University of Delaware disaster research experts can discuss the challenges communities face before, during and after hurricanes, including Hurricane Isaias and its potential impacts across Alabama, Mississippi, the Florida Panhandle and other parts of the northern Gulf Coast. The following experts from UD's Disaster Research Center are available to discuss the public health consequences of hurricanes, disaster preparedness and community recovery. Sarah DeYoung, associate professor of sociology and criminal justice, can discuss the needs of refugee and immigrant communities before, during and after disasters, including challenges accessing information, assistance and essential resources. She worked for several years with refugee and immigrant communities in southern Alabama through a grant-funded project. Jennifer Horney, professor of epidemiology, can discuss the public health consequences of hurricanes and other disasters, including evacuation decisions, the risks posed by inland flooding and the challenges communities face during recovery. She was part of the public health response to Hurricane Harvey and can discuss how communities still recovering from major storms may face additional challenges when another hurricane threatens the region. Jennifer Trivedi, associate professor of anthropology, studies how disasters affect marginalized communities. She can discuss how disasters compound existing challenges for people struggling to meet basic needs, particularly when flooding disrupts housing, transportation, food access and other essential services. Tricia Wachtendorf, co-director of the Disaster Research Center, can discuss the social impacts of hurricanes and inland flooding, including evacuation, preparedness, community response and recovery. She can also discuss how storms that are not the most powerful can nonetheless cause significant damage and disruption.

How should journalists cover politics when democracy is at stake

Political coverage often centers on the president, but according to the University of Delaware’s Dannagal Young, journalists can sometimes provide more meaningful coverage by focusing more on democracy and less on the commander in chief’s every movement. Young calls this approach “democracy-centered reporting.” Instead of treating every presidential announcement or provocative statement as the central event, democracy-centered reporting asks how political actions affect democratic institutions, constitutional principles and Americans’ ability to exercise their rights as citizens, Young says. Young, professor of communication and director of UD’s Center for Political Communication, says “access journalism” has an important role, but an overreliance on access can also make political leaders the organizing principle of coverage. In moments when executive power is expanding, she argues, journalists should consider whether their coverage is inadvertently amplifying the power they are trying to scrutinize. Young can discuss: • How journalists can cover presidents without making the president the center of every story • The benefits and risks of access journalism • How coverage of political conflict affects public understanding of democracy To arrange an interview with Young, visit her profile and click on the "contact" button.
