Chinese battery and electric vehicle manufacturer BYD has unveiled a new ultra-high-power charging system capable of delivering up to 1,500kW, alongside an updated version of its lithium iron phosphate battery technology.
The new system, known as Flash Charging, combines high-power charging infrastructure with the company’s second-generation Blade Battery, an LFP-based battery designed to support significantly faster charging while maintaining durability and safety.
According to BYD, the technology enables a 10–70% charge in around five minutes, while a 10–97% charge can be completed in approximately nine minutes under optimal conditions. Even in temperatures as low as –30°C, the system is designed to charge from 20–97% in around 12 minutes.
The company says the charging performance is the result of improvements in the electrochemical design of the Blade Battery 2.0, particularly enhanced ion transport within the lithium iron phosphate cells. These changes are intended to increase both energy density and charging speed while limiting degradation over repeated charge cycles.
The system is designed to operate with dedicated high-power charging stations capable of delivering up to 1.5MW through a single cable, placing it among the highest-power EV charging technologies announced to date.
The updated battery retains the key characteristics of LFP chemistry, including thermal stability, long cycle life and the absence of nickel and cobalt. LFP batteries have gained increasing market share in recent years, particularly in electric vehicles and stationary energy storage systems, due to their lower material costs and improved safety characteristics.
BYD said the technology has been developed to maintain fast charging performance across a wide temperature range, addressing one of the major limitations of many current EV batteries, where cold conditions can significantly reduce charging speeds.
BYD: Flash Charging installation in China will be followed by a European rollout
The company has already installed thousands of Flash Charging stations in China and plans to expand the infrastructure internationally, including an initial rollout in Europe.
The technology will make its European debut in April with the launch of the Denza Z9GT electric vehicle, although BYD said the charging system and battery platform are intended to support broader future applications across its electric vehicle portfolio. The official launch will take place at Paris’s Palais Garnier opera house on 8 April.
Stella Li, BYD executive vice president, said: “The introduction of the Denza Z9GT in Europe marks a very important milestone for our brand. The Z9GT represents the true spirit of Denza — where advanced technology, beautiful design and emotional driving come together.
“It’s the perfect choice to introduce the principle of ‘Ready in 5, Full in 9, Cold Add 3’ to the world, as we start our global rollout of Flash Charging in Europe. The ability to add hundreds of kilometres of range in just minutes, even in extremely low temperatures, means the Z9GT perfectly reflects our vision for Denza: technology that inspires, performance that excites and elegance that defines the future of premium mobility.”
