CATL has launched a new super hybrid battery that can achieve an electric range of over 400 kilometres and 4C superfast charging.
The Freevoy Super Hybrid Battery is the world’s first hybrid vehicle battery to achieve a pure electric range of over 400 kilometers and 4C superfast charging, its creators say.
According to global technology company CATL, the Freevoy Battery represents a new era for high-capacity EREV and PHEV batteries.
Range anxiety has been reported as a key issue for the uptake of electric vehicles in Australia. The Freevoy Battery has the potential to change the EV range game.

A transformative solution
With EREVs (extended range electric vehicles) and PHEVs (plug-in hybrid electric vehicles) gaining prominence in the new energy vehicle market, CATL says consumers have increasingly expressed frustration over their unsatisfactory pure electric experiences with such vehicles. Short range, slow charging, and reduced low-temperature performance have emerged as critical challenges demanding immediate solutions.
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 kilometres of range on 10 minutes of charging, effectively dispelling range anxiety for EREV and PHEV owners.
Freevoy’s technology
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 minimises 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 per cent. The overall pure electric utilisation rate has increased by more than 10 per cent, achieving a pure electric range of more than 400km.
At the same time, CATL conducted model data analysis on the charge-discharge polarisation characteristics of the battery, accurately predicted the future discharge capacity of the battery, and created a multi-level power prediction and control strategy for the battery. This improved the power performance of the hybrid vehicles by 20 per cent.
The Freevoy has already been used on numerous models of various brands, including Li Auto, AVATR, DEEPAL, CHANGAN NEVO, and NETA. By 2025, 30 hybrid vehicle models from brands including Geely, Chery, GAC, and VOYAH, equipped with CATL’s Freevoy are scheduled to be launched and delivered.
Looking to the future, CATL is pushing the boundaries of technological innovation, providing unmatched new energy experiences, and accelerating the shift toward comprehensive electrification.
