Successful test: in the US they managed to charge an electric car in 10 minutes technology



Ten-minute fee for 320 kilometers of autonomy: Scientists in the United States say they have made a technological breakthrough to solve one of the main concerns about electric vehicles.

Article published in the journal joule On Wednesday, researchers at Pennsylvania State University said such a fast charging rate requires a battery to quickly absorb 400 kilowatts of energy.

The vehicles of the current generation are not capable of this feat. lithiumformation of metallic lithium around the anode, which will severely impair the life of the battery.

To avoid this inconvenience, the researchers raised the temperature of their experimental batteries to 60 degrees Celsius during the charging cycle and then lowered them again when using them.

What is this Lay Limit the exposure of the battery to high charging temperatures, thus creating a very long service life ”The chief author of the article said Chao-Yang Wang, a mechanical engineer at Pennsylvania State University.

However, AFP member Rick Sachleben told AFP that it could take up to ten years for the design to be expanded and launched. American Chemical Society

Producers should ensure that the rapid increase in temperature is safe and stable and should not cause an explosion as extraordinary amounts of energy are transferred.

Electric vehicles of the brand Tesla The current production takes about 30 minutes for a partial charge.
