BYD Unveils Blade Battery 2.0 and Ultrafast Charging

Chinese electric vehicle manufacturer BYD unveiled its second-generation Blade Battery and ultrafast Flash charging technology on March 5, 2025, in Shenzhen, aiming to address key barriers to EV adoption amid a domestic sales slowdown. The lithium iron phosphate battery, which offers 5 percent higher energy density than its predecessor, enables charging from 10 percent to 70 percent in five minutes and up to 97 percent in under 10 minutes under normal conditions.

The announcement came during a technology event where BYD demonstrated the system's performance across several upcoming models. In one showcase, vehicles equipped with the new battery charged from 9 percent state of charge, adding over 1,000 kilometers of predicted range in under 10 minutes using 1,500-kilowatt Flash stations. Even in extreme cold at minus 20 degrees Celsius, the battery achieved a charge from 20 percent to 97 percent in about 12 minutes, adding 777 kilometers of range. These figures are based on China's CLTC testing cycle, which is generally more optimistic than international standards like the U.S. EPA.

The Blade Battery 2.0 will debut in up to 10 production models, including the luxury Yangwang U7...
