The launch of CATL’s Freevoy Super Hybrid Battery on October 24, 2024, represents a pioneering step in hybrid vehicle technology, setting new standards in range, charging speed, and adaptability for EREVs (extended range electric vehicles) and PHEVs (plug-in hybrid electric vehicles). Designed to address prevalent consumer challenges—short electric range, slow charging times, and poor low-temperature performance—the Freevoy offers a pure electric range exceeding 400 kilometers and 4C fast-charging capability, making it possible to drive over 280 kilometers after just 10 minutes of charging. These capabilities significantly enhance the practicality and appeal of hybrid vehicles, allowing users to complete a week’s commute on a single charge.
CATL achieved these advancements through innovative technologies in battery materials and design. The Freevoy integrates a surface modification technology for cathode material, an advanced high-voltage electrolyte, and a state-of-the-art SOC (State of Charge) management system, which increases control accuracy and range utilization by substantial margins. Further breakthroughs include CATL’s proprietary 4C ultra-fast charging technology and its sodium-ion battery application, which ensures reliable performance even in extreme temperatures, down to -40 degrees Celsius. To support system resilience, CATL has established a comprehensive reliability framework encompassing materials, manufacturing, and predictive analytics. Already used by brands like Li Auto, AVATR, and CHANGAN, Freevoy is poised for expansion, with 30 models featuring this technology set to launch by 2025.
