Farasis Energy has introduced a new battery technology that enables 6C ultra-fast charging, addressing the increasing demand from automakers for faster charging solutions. Jiang Weiran, Vice President of Research and Development at Farasis, reported that the company’s innovative design allows lithium iron phosphate (LFP) batteries to charge from 10 percent to 80 percent in approximately 8.55 minutes.
The breakthrough is attributed to Farasis’s internally developed simulation ROM model, which has optimized the battery design to support large pouch-style batteries capable of achieving this rapid charging rate. The term “C” denotes the battery’s charging rate, with 6C indicating that the battery can theoretically be fully charged in about ten minutes.
In addition to the 6C LFP batteries, Farasis has unveiled a lithium ternary battery system that supports 5C ultra-fast charging. This system enhances the heat dissipation area by four times for 5C ternary batteries and 4.8 times for 6C LFP batteries. The new Super Pouch Solution (SPS) structural design effectively mitigates the heat dissipation challenges typically associated with high-rate fast charging.
Both the 5C lithium-ion ternary and 6C LFP battery systems maintain charging temperatures below 50°C. When operating at 30°C, charge times are further reduced from 11.8 minutes to 10.2 minutes for the 5C ternary batteries, representing a 13.5% improvement, and from 10.28 minutes to 8.55 minutes for the 6C LFP batteries, showing a 16.8% enhancement.
Farasis’s ROM model also significantly accelerates the fast-charging simulation process, reducing the time required from 8-10 hours to just 10 seconds. This efficiency allows for the rapid exploration of optimal design solutions across various battery chemistries, including lithium, ternary, LFP, and sodium.
According to the China Automotive Battery Innovation Alliance (CABIA), Farasis Energy installed 0.19 GWh of batteries in January, positioning the company as the 14th largest power battery manufacturer in China with a market share of 0.48%.
