Research conducted by an American university used machine learning techniques to develop a system that allows you to recharge the battery of an electric vehicle in as little as 10 minutes.

Recharge an electric car in 10 minutes? It may soon be possible thanks to the new approach studied by researchers at the Idaho National Laboratory and presented at the autumn meeting of the American Chemical Society (ACS). The system uses machine learning, the so-called machine learningand artificial intelligence to allow a fast recharge in less than ten minutes to the different types of existing batteries, without damaging them.

“Speeding up charging is the key to increasing consumer confidence in electric,” said Eric Dufek, who presents the work. “This system would allow similar timings to those used in a gas station.” The study authors explained at the ACS meeting that charging a lithium-ion battery like the ones that power electric vehicles is a delicate balancing act. The ions migrate from the cathode to the anode, but moving too fast risks causing a build-up of lithium metal which causes the battery to deteriorate.
“Personalized” refill

Researchers from Idaho National Laboratory have developed a system that allows you to customize the charging protocol without damaging the battery. Through machine learning techniques, it will be possible to predict the duration of different types of feeding. “We have increased the amount of energy that can enter a cell in a short amount of time,” explained Dufek. “This approach allows you to charge over 90% of the battery in 10 minutes without causing lithium metal buildup or compromising components.” The ultimate goal will be to enable electric vehicles to provide charging stations with information on how to charge their batteries quickly and safely.
A more electric future

Now the research team will continue to work on optimizing this procedure, which will be able to give great impetus to electric propulsion, overcoming one of the public’s perplexities, the one related to recharging times. Thanks to this system, US President Joe Biden’s declared goal of making 50% of vehicles sold per year electric by 2030 appears closer.
