(Press-News.org) New shared language will facilitate faster service, improve EV user experience
The National Charging Experience Consortium (ChargeX) has released a report that recommends 26 common electric vehicle (EV) charging error codes to enable faster error reporting, diagnostics and resolution within the EV charging industry. Ultimately, the codes would improve the U.S. charging experience.
The ChargeX Consortium is a collaboration between U.S. Department of Energy national laboratories, EV charging industry experts, consumer advocates and other stakeholders.
The Recommendations for Minimum Required Error Codes report aims to reduce confusion between charger manufacturers, EV manufacturers and charging station operators, who currently use different messages to report similar errors. The common codes will simplify diagnostics when a charging session fails, improving EV charging network operations and charging experiences for drivers. Further, the codes will simplify diagnostics when a charging session faces an issue, streamlining EV charging network operations, reducing workforce training complexity and improving the charging experience for drivers.
"The landscape of the American road trip is changing,” said Gabe Klein, executive director of the Joint Office of Energy and Transportation, which funds ChargeX. “To make an electrified road trip convenient and reliable, companies in the EV charging ecosystem must be on the same page about how they communicate, especially when issues arise.”
Launched in August 2023, ChargeX — with expert help from Argonne National Laboratory, Idaho National Laboratory and the National Renewable Energy Laboratory — works to gauge and improve the customer experience with public EV charging infrastructure throughout the United States. This report is the first deliverable to serve that mission.
“We are excited to begin implementing these codes,” said Cuong Nguyen, manager of Industry Affairs and Standards at ABB Standards, a consortium industry participant and co-chair of the working group that led the report. “As a company that helped develop these common error codes, we hope to now demonstrate their value to others in the industry, leading to widespread adoption.”
ChargeX also published an implementation guide to help industry practitioners adopt the error codes uniformly and quickly, and additional industry recommendations will follow.
ChargeX industry participants ABB and EVgo demonstrated some of the error codes during the recent CharIN Testival North America 2023 in Cleveland, Ohio. “We are proud to work alongside ChargeX to implement root cause solutions that will lead to an elevated customer experience,” said Ivo Steklac, Chief Technology Officer at EVgo, one of the nation’s largest fast charging providers. “Standardized error codes, which apply to both vehicles and chargers, are foundational for understanding customer experience so the full EV ecosystem can march forward together towards solutions.”
About ChargeX
A collaborative effort between Argonne National Laboratory, Idaho National Laboratory, National Renewable Energy Laboratory, electric vehicle charging industry experts, consumer advocates, and other stakeholders, ChargeX’s mission is to work together to measure and significantly improve public charging reliability and usability by June 2025.

About the Joint Office of Energy and Transportation
The Joint Office was created through the Bipartisan Infrastructure Law (BIL) to facilitate collaboration between the U.S. Department of Energy and the U.S. Department of Transportation in their efforts to deploy a national network of electric vehicle chargers, zero-emission fueling infrastructure, and zero-emission transit and school buses.

Ending the HIV epidemic may require addressing “everyday” discrimination
2023-11-28
Latino sexual minority men who experience racial, ethnic and sexual prejudice are more likely to delay HIV testing, complicating efforts to end the more than 40-year epidemic, according to a new Rutgers study.
“Total HIV infection rates in the United States are stabilizing, which is good news,” said Gabriel Robles, an assistant professor at the Rutgers School of Social Work and coauthor of the paper published in the journal AIDS Education and Prevention. “What’s bad is that the trend for some subgroups, including some Latino/x sexual minority men, is going in the opposite direction. Our study offers ...
Anonymous $10 million gift to Henry Ford Health establishes lung cancer tissue repository, bolsters research
2023-11-28
As Lung Cancer Awareness Month comes to a close, Henry Ford Health is proud to announce it has received an anonymous gift of $10 million, which is poised to significantly advance lung cancer research at Henry Ford Cancer.
This transformative gift has enabled Henry Ford to establish a new lung cancer tissue biorepository, which is a facility that catalogs and stores biological samples for research. These samples – in this case, lung cancer tissue – are crucial for scientists who are studying ...
RCSI researchers develop material that reduces bacterial infection and speeds up bone healing
2023-11-28
28 November 2023: Researchers at RCSI University of Medicine and Health Sciences and Advanced Materials and Bioengineering Research Centre (AMBER) have developed a new surgical implant that has the potential to transform the treatment of complex bone infections. When implanted on an injured or infected bone, the material can not only speed up bone healing, it also reduces the risk of infections without the need for traditional antibiotics.
The newly published paper in the journal Advanced Materials, tackles the complex clinical problem of bone infection, ...
Contrast sensitivity of ON and OFF human retinal pathways in myopia
2023-11-28
Across the entire animal kingdom, visual images are processed by two major neuronal pathways that extract light and dark stimuli from visual scenes – ON (light on) and OFF (light off) pathways.
Light stimuli are brighter than their background like a white cloud in a gray sky whereas dark stimuli are darker than the background like a black bird in a blue sky. The two pathways can extract stimuli with different contrasts but some pathways are more sensitive than others. In carnivores and rodents, ON pathways are more sensitive ...
DFW air quality continues to miss EPA goals for safety
2023-11-28
Air quality in the Dallas-Fort Worth metropolitan area continues to miss safety levels set by the Environmental Protection Agency (EPA) and is unlikely to meet EPA goals anytime soon, according to new research from The University of Texas at Arlington.
Purnendu “Sandy” Dasgupta, professor of chemistry and biochemistry and the Hamish Small Chair of Ion Analysis at The University of Texas at Arlington, said the region’s low population density, lack of widespread public transportation and reliance on cars contribute to its poor air quality. Its ozone values have exceeded safety levels set by the EPA for the last 20 years.
“Compared ...
Many owners see little value in storing their firearms securely
2023-11-28
With more than 400 million privately owned firearms in circulation across the United States, gun violence prevention efforts have emphasized secure firearm storage as a method for preventing injury and death. But some owners may not see the value in doing so, according to Rutgers researchers.
Despite evidence that secure storage can effectively reduce the risk of suicide and unintentional shootings, many firearm owners typically keep at least one firearm stored loaded and unlocked, quickly accessible in case of home invasion. ...
