[Asia Economy Reporter Hyunjin Jeong] On the 27th (local time), The Washington Post (WP) reported that in five years, the charging speed of electric vehicles (EVs) could become faster than that of iPhone charging. If a method to charge 90% of an EV battery within 10 minutes is found and commercialized, the transition to electric vehicles is expected to accelerate rapidly.

According to the report, the Idaho National Laboratory under the U.S. Department of Energy recently announced in a report that it has found such a method. Currently, the fastest known charging takes about 20 minutes to 1 hour to fill 80% of the battery, but this can be significantly shortened.

The lead author of the study, Scientist Dupec, said, "The goal (of EV charging) is to get very close to the time it takes to refuel gasoline." The report expects it will take five years for this charging method to be commercialized and anticipates it will bring a fundamental change to EV charging.

This report came out as the Joe Biden administration accelerates the transition to electric vehicles, pouring billions of dollars into the process. In particular, it has focused on expanding infrastructure by investing in the installation of charging facilities, which are key to the widespread adoption of EVs.

WP reported that attempts to increase EV battery charging speed have faced issues such as long-term battery damage or even battery explosions. Therefore, research has been conducted to avoid stressing the battery.

Dupec’s research team used machine learning to understand how batteries are damaged during fast charging. They analyzed 20,000 to 30,000 data points indicating how well the battery is charging, as well as signs of aging or performance degradation.

The research team is working to find a method to charge beyond 10 to 15 miles per minute to 20 miles per minute over the next five years. Scientist Dupec said, "We can charge an EV battery up to 90% within 10 minutes, but we hope to do better."
