With this cold-resistant battery, electric cars could achieve an autonomy of 1,000 km

Greater Bay Technology, a Chinese startup, has announced that it has developed a battery that can withstand cold and heat and has a range of almost 1,000 km.

In winter, it is the tendon of war: the batteries of electric cars suffer a loss of performance, reducing autonomy and performance. Faced with this major problem in the electric car industry, a Chinese startup claims to have found the solution. As Electrek explains in a June 7 article, the fledgling Chinese company Greater Bay Technology claims to have developed its own technology to avoid loss of performance in charging and autonomy, in the face of harsh climatic conditions, especially in winter.

A durable, cold-resistant battery

As the manufacturer’s subsidiary GAC Motor explains in a presentation on WeChat, the use of superconducting materials in combination with precise thermal management would enable such a feat: in five minutes, the new battery, called Phoenix, can go from -20° C to 25°. C. Better yet, it could be charged 80% within six minutesin the words of company chairman Huang Xiandong.

Greater Bay Technology also claims that this revolutionary battery would enable a range of almost 1,000 km on a single charge and a level of performance that would not be affected by the outside climate. “The Phoenix battery not only solves the long charging time of electric vehicles, but also solves other problems. Whether hot or cold, its autonomy is not affected »said the startup’s president at Bloomberg.

A revolution coming soon?

Like many breakthrough batteries, the Phoenix lithium-ion battery is not yet in mass production, but it could be as early as next winter. Already recently marked with the development of eXtreme Fast Charge, enabling a full charge in fifteen minutes, Greater Bay Technology was once again able to assert itself in the electric vehicle battery market.

According to the Chinese company, the Phoenix battery should equip the parent company’s electric GAC Aion from 2024. And it could even be exported to multiple manufacturers: right now, the Chinese unicorn is in talks to distribute its battery. Competition in China will be fierce, with industry giants CATL and BYD also eager to make higher-performing batteries.

Currently, some vehicles not equipped with an active battery cooling system experience power loss. And in winter it is even common to observe a loss of autonomy.

But the development of such a battery, which can be charged very quickly and withstand extreme temperatures, could be a game-changer in the world of electric vehicle batteries, by making it possible to heat the battery efficiently and reducing costs. associated with cooling.
