(source: gbatteries official website) for the owners of electric vehicles, the endurance and charging time have always been big problems. Generally speaking, the life of fast charging battery is relatively short. In order to prolong the service life of battery, battery manufacturers often limit the charging speed. Gbatteries of Ottawa, Canada, tries to solve these problems. According to foreign media reports, gbatteries has developed a special adaptive pulse charging algorithm, which can accelerate the charging speed of almost all finished lithium-ion batteries without shortening the battery life. The technology sends the changing micro pulse current through artificial intelligence, and determines when to send the pulse under the appropriate voltage, without damaging the battery performance. In general, in order to cope with the impedance change during charging, the health status of the battery will be affected. By using the chargesense AI technology of gbatteries, when the battery is in the best low impedance state can be detected during charging, so as to determine the time to stop charging and depolarize to a certain extent, so as to avoid the common irreversible chemical reaction of the battery. This can not only accelerate the charging speed, but also reduce the temperature and prevent the battery from overheating or ignition. At present, researchers have tested the technology on hundreds of batteries for thousands of hours, so that the battery can be charged at ultra-high speed between 100mah and 60ah. The chemical composition of each cell is slightly different, so much remains to be done, the researchers said. However, they hope that in the near future, electric vehicles can be fully charged in 5 minutes. Of course, it depends on the power of the charging system.
