On the 6th, BYD unveiled its “second-generation Blade Battery” and “FLASH charging technology,” aiming to address two major EV challenges: limits on charging speed and weaker performance in cold weather.
BYD said the second-generation Blade Battery can reach near full charge within 10 minutes. It can charge from 10% to 70% state of charge in five minutes, and reach 97% in nine minutes, the company said.
In extreme cold of minus 30 degrees Celsius, BYD said charging from 20% to 97% takes only three minutes longer than at room temperature.
Developed after six years of research and development, the company said the battery is designed to offer a charging experience comparable to refueling a gasoline vehicle.
BYD Chairman Wang Chuanfu said the industry “must” solve persistent problems of slow charging and cold-weather performance, underscoring the significance of the new technology.
BYD also highlighted safety measures, saying it introduced a “lithium-ion high-speed channel” and an “all-around intelligent thermal management system” to reduce internal heat and improve heat dissipation. Energy density is up 5% from the first generation, it said.
The Denza Z9GT, equipped with the second-generation Blade Battery, achieved a driving range of 1,036 kilometers when combined with BYD’s lightweight body technology, the company said.
BYD said it is expanding FLASH charging stations with 1,500 kilowatts of output per single connector. It plans to build 20,000 FLASH charging stations across China and to roll them out in global markets in earnest by the end of this year.
