Many Chinese companies have announced breakthroughs in battery technology this year, with GAC Group-backed Greater Bay Technology as the latest.
Greater Bay unveiled the Phoenix battery, which claims to be able to charge from zero to nearly full in less than 10 minutes, at a battery technology launch event on June 6.
The Phoenix battery integrates Greater Bay's latest innovations in materials, electrochemistry, structure, and controls to give electric vehicles the ability to run as usual in all-weather conditions, it said.
Phoenix battery-equipped electric vehicles can be charged at up to 8C at different voltage platforms from 300 volts to 1000 volts, with 0-80 percent charging in 6 minutes, it said.
In the battery world, C refers to the charging multiplier, and 8C means the battery can theoretically be fully charged in one-eighth of an hour -- 7.5 minutes.
At the same time, Phoenix batteries offer leading-edge advantages in safety, cycle life, range and cost to compete with fuel-powered vehicles, Greater Bay said, according to a WeChat article it posted today.
Greater Bay said its technology gives the battery 18 times more heat exchange area compared to conventional solutions, and allows the pack temperature to rise from -20°C to +25°C in five minutes even in winter.
Phoenix battery uses a new structural design, not only the thermal management of the battery sees great improvements, volume utilization can be as high as 75 percent, it claimed.
With extremely fast charging, the Phoenix battery also has an ultra-long life, with a cycle life of 10 years or 800,000 kilometers, the company said.
The battery system's highly integrated design allows for an energy density of 260 Wh/kg and a range of 1,000 kilometers on a single charge, it said.
Phoenix batteries will be in mass production next year and are expected to be used in production vehicles by the end of next year, according to the company.
Greater Bay, founded in September 2020, is a battery maker incubated by GAC, according to its website.
The company is building cell and pack production capacity, with a pack plant in Nansha, Guangzhou, already in operation.
Greater Bay plans to build a production base of about 500 mu (33 hectares) in Guangzhou, with the first phase of construction expected to be completed in 2023 and a capacity of 8 GWh, which could supply batteries for 120,000 vehicles, the information on its website reads.
