BYD officially unveils its second-generation Blade Battery and a new Flash Charging technology

The Chinese manufacturer BYD has officially introduced its second-generation Blade Battery and new Flash Charging technology that is said to overcome two issues of battery electric vehicles (BEVs): slow charging speeds and poor battery performance in extreme temperatures.

The next generation Blade Battery and FLASH Charging Technology arrives.

Setting a new benchmark for safety, efficiency and performance in electric mobility.

The new second-generation Blade battery offers 5% higher energy density when compared to the original version, and BYD has increased the guaranteed capacity retention rate by 2.5% and promised a lifetime warranty on the battery cells.

It can charge from 10% to 70% in 5 minutes and 10% to 97% in 9 minutes (at room temperature), while at -30 degrees Celsius, extreme cold temperature, it charges from 10% to 97% in 12 minutes.

It is said that this second-generation Blade Battery delivers a driving range of up to 1,006 km (621 miles) on the (optimistic) CLCT cycle, an improvement from the ~600km (373 miles) range in the first-generation Blade battery. The new battery would likely mean a 450-mile range if tested on the EPA cycle.

The company has revealed that ten BYD models will be the first to feature this battery. They have already used the battery in two cars in China: the Yangwang U7 equipped with a 150-kWh battery pack is said to achieve a pure electric range of 1,006km, while the fully electric Denza Z9GT have a range of up to 1.036km on the CLTC cycle.

To support ultra-fast charging, BYD has also developed a Flash charger that delivers an output of 1,500kW through a single connector. BYD’s flash charger is the world’s first rail-mounted suspended T-type charger with a zero gravity design. The cable supports the connector, making it feel extremely light and easy to use.

BYD aims to expand its “Flash Charging” network to 20,000 stations by the end of 2026, including 2,000 on highways.
