MILAN (ITALPRESS) – BYD takes a new step in the development of electric mobility by introducing two technologies to change industry standards: the FLASH Charging system and the Blade Battery 2.0. The goal is to overcome one of the main barriers to large-scale diffusion of electric cars, i.e. charging times and battery performance in difficult weather conditions. BYD’s new proprietary charging system is able to deliver up to 1,500 kW through a single connector, allowing extremely low charging times. With this technology, a battery can pass from 10% to 70% in just five minutes, while to reach 97% it takes about nine minutes. Notable performance even in the most extreme conditions: at -30°C the system is still able to bring a battery from 20% to 97% in about 12 minutes, thus limiting one of the main problems of electric cars in colder climates. The Blade Battery 2.0 is the second generation of the battery developed by BYD after six years of research. The new accumulator introduces an increase of 5% of the energy density, which allows autonomy over 1,000 kilometers according to the Chinese CLTC cycle, maintaining high safety standards and durability. The improvement was possible thanks to the FlashPass ion transport system, which optimizes the movement of lithium ions through three main innovations: the Flash-Release cathode, designed to facilitate a faster release of ions; the Flash-Flow electrolyte, developed with artificial intelligence algorithms to increase the ion conductivity; and the Flash-Intercalate anode, with a three-dimensional structure that allows 360 lithium-degree insertion. These solutions reduce the internal resistance of the battery and limit the generation of heat during charging. Further progress concerns the SEI layer (Solid Electrolyte Interphase), made thinner but at the same time more stable thanks to molecular engineering techniques. The battery also incorporates dynamic self-repair technology, which contributes to improving durability and reliability over time. From the safety point of view, the Blade Battery 2.0 has passed new extreme tests, including simultaneous FLASH charging with Nail Penetration Test, without thermal runaway phenomena, smoke or fire even after 500 fast charging cycles. Further tests have simulated multiple short circuits with temperatures above 700°C, without causing explosions or fires. In parallel to the development of batteries, BYD is expanding the charging infrastructure: 4.239 FLASH Charging stations are already operating and the company aims to reach 20,000 units by the end of the year. Each station integrates ultra-fast discharge energy storage systems to manage peak demand and reduce dependence on the local electricity network. The European debut of the new technology will take place with the DENZA Z9GT, shooting brake grand tourism of the premium brand Denza, controlled by BYD. The car will adopt a 1000 volt architecture and can offer up to 800 kilometers of autonomy in the Long Range version, while the three-motor variant will be oriented to the performance with an estimated autonomy of about 600 km. The European presentation of Denza models is scheduled for April, while the start of the production of the Long Range version is scheduled for August, with the first deliveries to customers by the beginning of the last quarter of the year. With these innovations, BYD aims to permanently reduce the charging times of electric cars, bringing them closer to the speed of a traditional supply.
