Chinese battery manufacturer CATL has recently unveiled its brand-new Freevoy Super Hybrid battery, the world’s first hybrid vehicle battery to achieve a pure electric range of over 400 kilometers and 4C superfast charging.

Designed for hybrid vehicles of EREVs and PHEVs, CATL’s Freevoy frees drivers from the constant need to charge, a common drawback of existing hybrid vehicles, offering the convenience of one charge to power an entire week’s commute. Additionally, it delivers impressive charging speeds, providing over 280 kilometers of range on 10 minutes of charging, according to the Chinese company.

The Freevoy incorporates a surface modification technology for the cathode material, coupled with an innovative high-voltage electrolyte formulation, to create a nano protective layer. This effectively minimizes side reactions within the active layer. The integration of high-activity, excited-state particles into the cathode material significantly enhances transport efficiency of lithium ions within the material. Supported by the SOC full-scene high-precision model developed by CATL, and the upgrade of BMS intelligent algorithm and hardware, the SOC control accuracy of Freevoy has been increased by 40%, and the overall pure electric utilization rate has increased by more than 10%, achieving a pure electric range of more than 400km.

CATL’s Freevoy: ultra-fast charging technology and improved chemistry

Furthermore, CATL has successfully applied its 4C ultra-fast charging technology in the Freevoy, achieving over 280 kilometers of range on 10 minutes of charging. In addition, CATL’s sodium-ion battery technology is also implemented in the Freevoy, breaking the low-temperature limitations of new energy vehicles. It achieves discharge capability in extreme cold environments down to -40 degrees Celsius, charging capability down to -30 degrees Celsius, and maintains a seamless driving experience down to -20 degrees Celsius comparable to normal temperatures. To sum up, the Freevoy combines sodium-ion batteries and lithium-ion batteries in a defined ratio and arrangement, with mixed, serial, and parallel connections to enhance low-temperature range by 5%.

Such an innovative battery has been repeatedly tested in the passenger car sector, so far.
