Farasis Unveils 6C Ultra-Fast Charging Battery Technology
Farasis Energy has introduced a groundbreaking battery technology that enables 6C ultra-fast charging, meeting the increasing demands for quicker charging solutions from automakers. According to Jiang Weiran, the vice president of research and development and president of the R&D institute, the company has optimized its battery design using an in-house developed simulation ROM model. This innovation allows large pouch-style batteries to achieve 6C fast charging at the system level.
The term “C” refers to the battery’s charging multiplier, meaning that 6C indicates the battery can theoretically be fully charged in just 10 minutes. The new solution features a lithium iron phosphate (LFP) battery system that supports 6C ultra-fast charging, alongside a lithium ternary battery system capable of 5C ultra-fast charging. Farasis has emphasized that its SPS (super pouch solution) structural design significantly enhances the heat dissipation area—by four times for 5C ternary batteries and by 4.8 times for 6C LFP batteries.
The company asserts that its battery design effectively addresses the heat dissipation challenges associated with high-rate fast charging. Utilizing the ROM and fast-charging optimization models, both the 5C lithium-ion ternary battery and the 6C LFP battery systems maintain fast-charging temperatures below 50°C. Under an ultra-fast charging environment at 30°C, the time required to charge from 10 percent to 80 percent state of charge (SOC) has been reduced from 11.8 minutes to 10.2 minutes—representing a 13.5 percent improvement for the 5C Li-ion ternary battery—and from 10.28 minutes to 8.55 minutes—a 16.8 percent decrease for the 6C LFP battery.
Farasis claims that its ROM model enhances battery design efficiency and performance by optimizing design boundaries and simplifying conditions to obtain core parameters. Notably, for pack fast-charging simulations, the ROM model completes its calculations in just 10 seconds, significantly faster than the 8-10 hours required by conventional commercial software. This model can quickly identify optimal design solutions for lithium ternary, LFP, and sodium battery chemistries by deeply analyzing the working principles of the batteries.
As one of China’s largest power battery manufacturers, Farasis Energy installed 0.19 GWh of batteries in January, ranking 14th in the country with a 0.48 percent market share, according to the China Automotive Battery Innovation Alliance (CABIA).
In related developments, CATL and BYD are reportedly working on even faster 6C charging technologies.
