An Israeli fast-charging specialist claims to have made a breakthrough allowing battery electric vehicles to be charged in 10 minutes without stressing the battery pack and shortening service life.
StoreDot says its silicon-dominant extreme fast-charging battery cells have successfully passed a long-term set of trials. Its results claim that consecutive extreme fast charging did not degrade battery cells, even after 1,000 consecutive charging cycles.
The company says during full-cycle charge tests, designed to replicate how ordinary consumers may use the technology, extreme fast charging was applied from 10% to 80% of battery capacity in 10 minutes, with the remaining charging cycle from 0%-10% and 80%-100% performed with slower charging. In parallel, these silicon battery cells also were tested for slow-charging cycles from 0% to 100% and also achieved a similar cycle life performance.
Despite each cycle applying this form of charging for most of the charge, at 70% for example, the company claims its cells demonstrated no additional degradation, a result on a par with cells that were slow charged from 0%-100%.
The company claims it has achieved this breakthrough by synthesizing proprietary organic and inorganic compounds and then applying artificial-intelligence algorithms to enhance the process. It claims this now means a BEV can be charged in less than 10 minutes to rival the consumer experience of visiting a service station to refuel a conventional ICE-powered vehicle.
Dr. Doron Myersdorf, StoreDot CEO, says: “The significance of testing our silicon batteries under various use-case conditions demonstrates our battery's robustness regardless of drivers’ charging habits, recharging frequency or charger power.”
