BYD Blade Battery 2.0 and FLASH Charging at 1500 kW: 10% to 97% in nine minutes

Price, driving range and charging times are often cited as the biggest hurdles to widespread electric vehicle adoption. Even so, those barriers have been steadily reduced - and BYD has now taken another significant step.

The Chinese manufacturer has unveiled the latest generation of its lithium iron phosphate (LFP) Blade Battery 2.0. When paired with its ultrafast FLASH Charging system rated at 1500 kW (!), BYD says it can take just nine minutes to raise the state of charge from 10% to 97%. Even with the thermometer reading -30 °C, BYD claims the same top-up takes only 12 minutes.

BYD chemical and thermal efficiency

Compared with the previous generation, the Blade Battery 2.0 brings a 5% increase in energy density, but the most meaningful development is in how ion flow is managed between the cathode and the anode. BYD calls this the FlashPass Ion Transport system and says it pushes LFP battery capability to the limit.

According to the brand, the system introduces three improvements - across the cathode, the anode and the electrolyte - lowering internal resistance and allowing extremely high charging power without creating excessive heat at the source:

• “Flash-Release” cathode: a multi-level architecture with particles of different sizes and controlled orientation, enabling high density and rapid ion release;
• “Flash-Flow” electrolyte: optimised using artificial intelligence to deliver high ionic conductivity and fast ion mobility;
• “Flash-Intercalate” anode: a three-dimensional structure with multiple lithium insertion sites, enabling 360° high-speed lithium-ion intercalation.

BYD also states that durability and safety are not compromised. The company put the new battery through a nail penetration test while it was receiving the maximum 1500 kW charge, and reports there was no thermal runaway or fire - even after 500 fast-charging cycles.

1500 kW charging power

To handle this energy throughput, BYD has developed further advances in the FLASH Charger: ultrafast charging stations that can deliver up to 1500 kW (or 1.5 MW) through a single connector (specifications for the Chinese market). By comparison, Europe’s most powerful charger was installed in Portugal and delivers 1000 kW, or 1 MW (Megawatt): take a look at it.

BYD has already installed 4239 FLASH Charging stations in China (data as of 5 March 2026) and expects to reach 20,000 units in operation by the end of 2026. The stations include their own energy storage systems (battery), capable of ultrafast discharge. These act as “reservoirs” to prevent overloading the electricity grid and as boosters for very high-power charging.

When will it reach the European market?

The first model to arrive in Europe equipped with the Blade Battery 2.0 will be the Denza Z9 GT - which was recently updated - and its final European specifications have not yet been announced. However, we were already able to see the Z9 GT in person last year:

BYD has also committed to making its FLASH charging stations available globally, with more details on its international expansion plan expected in the coming weeks.
