Chang Sha Wan Bao·2026-03-06 07:16Core Viewpoint - BYD has officially launched its second-generation blade battery and flash charging technology, achieving the fastest charging speed in the world, which addresses the common issues of slow charging and low-temperature charging difficulties in electric vehicles [1][3]. Group 1: Flash Charging Technology - The new technology allows charging from 10% to 70% in just 5 minutes and from 10% to 97% in 9 minutes, even at -30 degrees Celsius, with only a 3-minute increase compared to normal temperatures [1][3]. - The second-generation blade battery has improved energy density by over 5% compared to the first generation, while also enabling fast charging [3]. - The battery features a "lithium-ion high-speed channel" and an "all-temperature intelligent thermal management system," which minimizes heat generation and ensures efficient heat dissipation, thus preserving battery life during fast charging [3][4]. Group 2: Safety and Warranty - The second-generation blade battery has undergone rigorous safety testing that exceeds new national standards, ensuring user safety throughout the battery's lifecycle [4]. - The warranty for the second-generation blade battery has been enhanced, with a 2.5% increase in "capacity retention rate," and the battery cells continue to have a "lifetime warranty" [3]. Group 3: Flash Charging Infrastructure - BYD has initiated the "Flash Charging China" strategy, aiming to build 20,000 flash charging stations nationwide by the end of the year, with 18,000 stations expected to be completed in collaboration with charging network operators [6]. - The coverage plan includes ensuring that users in first and second-tier cities have access to a flash charging station within 3 kilometers, while third and fourth-tier cities will have stations within 5 kilometers [6]. - BYD's "Flash Charging Highway Stations" will cover nearly one-third of highway service areas, with 2,000 stations expected to be completed by the end of the year, providing charging stations approximately every 100 kilometers [6].
