BYD Blade Battery 2.0 Revealed with 1500kW Charging Capability

The second-generation BYD Blade Battery – imaginatively dubbed ‘Blade Battery 2.0’ – has been revealed and it revolutionises electric vehicle technology.

Combined with BYD’s new Super e-Platform with its 1000-volt architecture and its self-developed FLASH charging system, the Blade Battery 2.0 can support charging speeds of up to 1500kW.

In a statement BYD said: “Despite remarkable gains in EV market penetration in most significant new-car markets worldwide, the fact remains that most buyers of pure-ICE vehicles don’t pay much attention to the size of a car’s fuel tank, whereas many EV customers are focused on battery capacity and range, even paying significant premiums for a few kilometres more.”

At a technology showcase in 2025 revealing the brand’s Super e-Platform, BYD Chairman and President, Wang Chuanfu, stated the aim of the technology was to “make charging as quick as refueling a gasoline car.”

BYD claims the combination of its battery, charging and electrical technology can recharge a Blade Battery 2.0 from 10-70 per cent in five minutes and from 10-97 per cent in nine minutes.

What’s more, it is far more tolerant of cold temperatures, able to fill a battery from 20-97 per cent in 12 minutes in -30°C.

A five per cent gain in energy density will allow BYD to offer vehicles with up to 1000km of range based on China’s CLTC efficiency testing, while advances in battery durability reduce capacity degradation by 2.5 per cent.  

The Blade Battery 2.0 is the culmination of six years of research, which for the technically minded among you uses a “‘Flash-Release’ cathode with a directionally engineered, multi-level particle-size architecture that enables dense packing and repaid deintercalation.”

Furthermore, “the ‘Flash-Flow’ electrolyte uses AI-driven precision optimisation to deliver high ionic conductivity and fast ion mobility” and “the ‘Flash-Intercalate’ anode has a multi-dimensional lithium-insertion site construction, allowing 360-degree 3D high-speed lithium-ion intercalation.”

In layman’s terms, there is significantly reduced internal resistance with far less heat generation.

To ensure the new battery’s safety, BYD created new safety evaluations, including the first simultaneous FLASH charging and nail penetration test, which resulted in no thermal runaway, smoke or fires, even after 500 charging cycles.

BYD also forced a short circuit of four cells simultaneously, but thermal runaway still did not occur even when battery temperature reached 700°C.

Of course, the vehicle is only half the equation, but BYD has rolled out 4239 of its 1500kW FLASH charging stations across China at the time of writing with plans for 20,000 by the end of 2026.

These stations use an ultra-fast-discharge energy storage system, using a battery that is recharged at slower speeds that acts as both an energy reservoir to prevent grid overload and a power amplifier for high-speed charging.  

BYD has committed to a global rollout of its FLASH chargers, including in Australia, but a timeline has not yet been revealed for these plans.  

Currently, only the BYD Han L and Tang L are built on the Super e-Platform, but it is expected to underpin many of the brand’s next-generation models, while the Denza Z9 GT from its luxury arm will be the first export product to use Blade Battery 2.0.
