Electric car batteries can be "accelerated" up to five times on charging
The process of massification of electric cars has largely benefited the development projects of lithium-ion batteries, however, as the University of Warwick underlines in a new study, there is still a lot of room for improvement. According to a group of researchers from the British institution, the batteries used in electric cars can be charged up to five times faster than the current average time.To reach this conclusion, the team developed a sensor capable of measuring the internal temperatures of the batteries during charging, and applied it to the batteries that Tesla uses in Model S and X. Then proceeded to load one of them, increasing gradually the power of the power supply, and noted that lithium-ion can withstand more power without overheating.Currently, the batteries integrate a system that prevents them from reaching temperatures above a certain value in order to minimize the risk of overheating, but the University of Warwick's findings prove that this limit can be extended without associated risks.Tazdin Amietszajew, responsible for the project, explains that the exhaustive use of this system can reduce the useful life of a battery, but stresses that sporadic application, in cases of emergency or greater convenience, has a minimal impact on this variable.

The commercialization of this system can not only improve the lives of drivers of electric vehicles, but also serve as an argument to attract new consumers.
