Hongqi's new experimental battery can reportedly charge from 10% to 70% in under four minutes, and go from 10-97% in about 8. It was only last year that five-minute EV charging debuted in China, promising to finally make topping up an EV similarly quick to filling up a combustion car. The battery, developed together with specialist Lishen Battery, can reach a peak charging rate of 12C. However, the automaker has not revealed the battery’s capacity, peak charging power or chemistry. CATL recently announced a new battery for commercial vehicles that claims a 20% to 80% charge time of under seven minutes, with a full charge taking two additional minutes.
