Chinese new energy company BYD has unveiled the second generation of its so-called Blade battery which now can reportedly charge from ten to 70 percent in five minutes and from ten to 97 percent in just nine minutes. This feature is branded by BYD as “flash charging.”
Providing lifetime warranty
In addition to the cellsʼ charging performance, BYD cites an increase in energy density of more than five percent. The company is also increasing guaranteed capacity retention by 2.5 percent and will offer a lifetime warranty on the cells. Initially, ten electric vehicle models will be equipped with the battery, including the Yangwang U7, which has a 150 kilowatt-hour pack and a claimed electric range of 1,006 kilometers, as well as the Denza Z9GT, which boasts a range of up to 1,036 kilometers.
Numerous tests passed
BYD also classifies the system as a solution for charging at low temperatures. Charging from 20 to 97 percent reportedly takes only twelve minutes at minus 30 degrees Celsius. The company cites a general speed advantage of 30 to 50 percent over other batteries in electric vehicles for charging at standard charging stations. Safety tests included a nail penetration test performed during charging after 500 fast-charging cycles, with no smoke or open flames. Additionally, underbody impact tests were conducted with ten times the force required by Chinese standards. A thermal runaway scenario was also performed with four short-circuited cells, resulting in no fire or explosion of the pack.
Own network planned
To take full advantage of the batteriesʼ fast charging speed, BYD plans to build its own network of flash charging stations with up to 1,500 kilowatts and 1,000 volts. A total of 20,000 stations are expected to be operational by the end of 2026. Currently, there are said to be 4,239 completed locations to be commissioned in the immediate future.
