FAW Hongqi Ultra-Fast Charging Battery Completes 8-Minute Charging Test

FAW Hongqi Ultra-Fast Charging Battery Achieves Major Charging Performance Milestone

According to the FAW R&D Institute on July 27, the FAW Hongqi Ultra-Fast Charging Battery jointly developed with China Automotive New Energy Battery Technology Co Ltd recently completed charging performance testing at 25°C. Test results showed that the battery charged from 10% to 70% state of charge (SoC) in 3 minutes and 41 seconds, while reaching 97% SoC from 10% in only 8 minutes and 3 seconds. The achievement highlights advancements in electric vehicle battery charging speed and energy efficiency.

The ultra-fast charging battery uses a high-efficiency anode design developed for rapid energy transfer, enabling a peak charging rate of 12C. Through optimized battery architecture and advanced materials, the system improves charge transfer efficiency and charging responsiveness. The technology development reflects increasing efforts by China based automotive companies to enhance electric vehicle performance through next-generation battery solutions. The battery technology is designed to support faster charging experiences while maintaining operational stability during demanding usage conditions.

The battery also integrates an intelligent liquid-cooling system that maintains consistent temperature distribution across battery cells. Combined with a full-scenario multi-level thermal management strategy, the system keeps the battery within its ideal operating temperature range while reducing energy consumption required for thermal control. These improvements are aimed at increasing battery reliability, supporting repeated fast charging cycles, and improving overall electric vehicle efficiency for future passenger car applications.

In addition, the battery adopts an adaptive fast-charging strategy based on safe operating boundaries. The system continuously monitors and controls cell temperature rise throughout the charging process to prevent abnormal conditions such as overcharging and overvoltage. Through intelligent monitoring and safety-focused control algorithms, the technology aims to balance charging speed with battery protection. The collaboration between FAW Hongqi and China Automotive New Energy Battery Technology Co Ltd demonstrates continued development toward high-performance electric mobility solutions.
