7-minute battery charging
Singaporean company KVI, founded by Moroccan scientist Rachid Yazami, announced that it charged a lithium iron phosphate battery cell from 10% to 70% in 3 minutes and 42 seconds, and from 0% to 100% in 7 minutes, while keeping the temperature below 50°C. The company noted that the test was conducted on a single commercial cell, not a complete electric-car battery pack, so it does not mean an electric car can regain its full range in 7 minutes. The technology is based on “nonlinear voltammetry,” which adjusts the voltage gradually and allows the current to adapt to electrochemical changes inside the cell.
