MILAN (ITALPRESS) – BYD takes another step forward in the development of electric mobility by introducing two game-changing technologies: the FLASH Charging system and Blade Battery 2.0. The aim is to overcome one of the main barriers to widespread adoption of electric vehicles: charging times and battery performance in challenging climatic conditions. BYD’s proprietary new charging system can deliver up to 1,500 kW through a single connector, significantly reducing charging times. With this technology, a battery can be charged from 10% to 70% in just five minutes, while reaching 97% takes approximately nine minutes. Remarkable performance is also maintained in extreme conditions: at -30°C, the system can elevate a battery from 20% to 97% in about 12 minutes, addressing a key challenge for electric vehicles in colder climates. The technological advancement is rooted in the Blade Battery 2.0, the second generation of batteries developed by BYD after six years of research. This new accumulator features a 5% increase in energy density, allowing for ranges exceeding 1,000 kilometers under the Chinese CLTC cycle, while maintaining high safety and durability standards. This improvement has been facilitated by the FlashPass ionic transport system, which enhances the movement of lithium ions through three key innovations: the Flash-Release cathode, designed for faster ion release; the Flash-Flow electrolyte, developed using AI algorithms to improve ionic conductivity; and the Flash-Intercalate anode, featuring a three-dimensional structure that allows for 360-degree lithium ion insertion. These solutions reduce the internal resistance of the battery and limit heat generation during charging.
Additional improvements involve the SEI (Solid Electrolyte Interphase) layer, which has been made thinner yet more stable through molecular engineering techniques. The battery also includes a dynamic self-repair technology that enhances longevity and reliability over time.
In terms of safety, the Blade Battery 2.0 has passed new extreme tests, including simultaneous FLASH charging with the Nail Penetration Test, showing no thermal runaway, smoke, or fire even after 500 rapid charging cycles. Further testing simulated multiple short circuits at temperatures exceeding 700°C without triggering explosions or fires. Concurrently with battery development, BYD is expanding its charging infrastructure: there are already 4,239 FLASH Charging stations operational, and the company aims to have 20,000 by the end of the year. Each station incorporates ultra-fast energy storage systems to manage peak demand and reduce reliance on the local electricity grid.
The European debut of the new technology will occur with the DENZA Z9GT, a grand touring shooting brake under the premium Denza brand, controlled by BYD. This vehicle will adopt a 1000-volt architecture and offer up to 800 kilometers of range in the Long Range version, while the three-motor variant will focus on performance with an estimated range of around 600 km. The European presentation of the Denza models is scheduled for April, while production of the Long Range version is planned to start in August, with the first customer deliveries expected by early Q4 of the year. With these innovations, BYD aims to significantly reduce electric vehicle charging times, bringing them closer to traditional refueling speeds.
