BYD's 'Flash Charging' promises fast EV refills

BYD's new charging system uses a 1,500-kW charger and their second-generation Blade Battery to achieve these speeds. In optimal conditions, it can charge from 10% to 70% in about 5 minutes, and from 10% to 97% in roughly nine. Even in subzero temperatures (-30°C), a 20% to 97% charge takes approximately 12 minutes. The charging stations feature a T-shaped overhead cable system, keeping connectors off the ground for easier use. As of early March 2026, BYD had already installed over 4,200 of these stations in China and plans to deploy 20,000 by the end of the year. The stations also include energy storage systems to deliver ultra-high charging power, even where local electrical grids have limitations. The second-generation Blade Battery improves both charging speed and energy density. It increases energy density by about five percent compared to the original, enabling driving ranges of over 621 miles (1,000 kilometers) under China's CLTC test cycle. This could translate to well north of 400 miles EPA. BYD's "FlashPass" ion transport system uses a specially designed cathode, electrolyte, and anode that reduce internal resistance and heat buildup. This allows for faster lithium-ion movement within the battery, making it safer and more durable. The first vehicle expected to use the new technology in Europe will be the Denza Z9GT, a premium electric wagon from BYD's luxury sub-brand Denza.
