A new battery called the Freevoy Super Hybrid Battery is set to improve plug-in hybrid electric vehicles (PHEVs) and extended range electric vehicles (EREVs). This innovative battery can travel over 400 kilometres on a single charge and supports ultra-fast charging.
Better Charging for PHEVs
The Freevoy battery’s impressive range comes from advanced technology that enhances its materials. It uses a new high-voltage liquid to create a protective layer, which helps reduce unwanted reactions inside the battery. By adding special particles to the battery’s structure, the movement of lithium ions becomes more efficient.
According to CATL, “The SOC control accuracy of Freevoy has been increased by 40 per cent, and the overall pure electric utilisation rate has increased by more than 10 per cent.” This means the battery can predict how it will perform in the future. As a result, it has led to a new strategy that improves the power performance of hybrid vehicles by 20 per cent.
The Freevoy battery can also deliver over 280 kilometres of range with just 10 minutes of charging. This is thanks to CATL’s 4C ultra-fast charging technology. This technology allows lithium ions to move easily through the battery. It uses a special coating, advanced materials, and a new type of liquid to enhance conductivity. As a result, hybrid vehicles can charge as quickly as fully electric cars.
Performance in Cold Weather
CATL designed the Freevoy battery to work well in cold temperatures, using its sodium-ion battery technology. It can operate in conditions as low as -40 degrees Celsius for discharging and -30 degrees Celsius for charging, providing a smooth driving experience even at -20 degrees Celsius.
To enhance cold-weather performance, CATL has introduced three key innovations. First, the Freevoy combines sodium-ion and lithium-ion batteries in a specific way. This design boosts performance in cold weather by 5 per cent.
Second, it uses the sodium-ion battery to help keep track of the lithium-ion battery’s charge, improving control accuracy by 30 per cent and adding over 10 kilometres to the pure electric range.
Finally, CATL has developed a special system that manages battery performance in varying temperatures. This system prevents problems like inaccurate charge predictions and reduced power output in extreme conditions.
Several vehicle models from different brands are already using the Freevoy battery. This includes Li Auto, Avatr, Deepal, Changan Nevo, and Neta.By 2025, brands such as Geely, Chery, GAC, and VOYAH will launch 30 new hybrid vehicle models featuring the Freevoy battery.
As more people seek sustainable travel options, this new battery aims to make driving easier and more efficient.
