BYD's 5-Minute Flash Charging Battery
BYD launched its second-generation Blade Battery with flash charging in just five minutes and plans for 20,000 flash charging stations across China. The company also unveiled a 1,500 kW ultra-fast EV charger that sets new standards for range and charge times in EVs.
The second-generation Blade Battery incorporates a significant chemistry upgrade, moving from standard Lithium Iron Phosphate (LFP) to Lithium Manganese Iron Phosphate (LMFP). This change, combined with a new silicon-carbon anode, increases system-level energy density to 190-210 Wh/kg, a notable improvement over the first generation's approximate 140 Wh/kg. While the headline figure is five minutes, the specifics are a 10% to 70% state of charge. A more complete charge from 10% to 97% takes approximately nine minutes. In vehicles like the Denza Z9GT, this new battery technology enables a driving range of over 1,000 km (CLTC). A key advancement is the battery's performance in extreme cold, a traditional weakness for LFP chemistry. Even at temperatures of -20°C and -30°C, the battery can charge from 20% to 97% in just
