Chinese battery manufacturer Farasis Energy has introduced a new battery technology capable of 6C ultra-fast charging, aiming to meet the growing demand from automakers for higher charging speeds.
At a recent forum in Shanghai, Jiang Weiran, vice president of research and development at Farasis, said the company had optimized its battery design using an in-house simulation ROM model, enabling large pouch-style batteries to achieve 6C fast charging at the system level. “Our structural design significantly enhances heat dissipation, addressing the key challenges of high-rate charging,” Jiang said, according to a company statement released.

The new technology includes a lithium iron phosphate (LFP) battery system supporting 6C ultra-fast charging and a lithium ternary battery system supporting 5C ultra-fast charging. Farasis said its Super Pouch Solution (SPS) structural design improves heat dissipation by a factor of four for ternary batteries and 4.8 times for LFP batteries, helping maintain battery temperature within 50°C during fast charging.
Farasis also noted that under an ultra-fast charging environment at 30°C, the 5C lithium ternary battery reduced its charge time from 10 percent to 80 percent state of charge (SOC) by 13.5 percent to 10.2 minutes, while the 6C LFP battery cut its charging time by 16.8 percent to 8.55 minutes.

The ROM model used by Farasis speeds up pack fast-charging simulations, reducing computation time from 8-10 hours in traditional commercial software to just 10 seconds, the company said.
Farasis, one of China’s leading battery manufacturers, had 0.19 GWh of batteries installed in January, ranking 14th in China with a 0.48 percent market share, according to the China Automotive Battery Innovation Alliance.
