With Enhanced Low-Temperature Performance, Changan Automobile and CATL Jointly Unveil Global Sodium-Ion Battery Strategy
On February 5, Changan Automobile, in collaboration with CATL, unveiled its latest global strategy for sodium-ion batteries in Yakeshi. The event also featured a comprehensive overview of Changan Automobile’s new intelligent safety innovations under the Tianxu brand. At this launch event, Changan Automobile made a high-profile announcement: the brand-new sodium-ion battery has now entered the stage of testing in production vehicles, offering a pure-electric range of over 400 km. Moreover, the battery maintains its full operational efficiency even at temperatures as low as -30°C.
In today’s era of intelligent vehicle development, in addition to comfort and cutting-edge technology, Changan Automobile has also achieved a key breakthrough in the field of battery safety, ushering in another major milestone: jointly launching a sodium-based battery ecosystem solution with its strategic partner, CATL, and creating “the world’s first mass-produced passenger car equipped with sodium batteries,” thus inaugurating a new era of “the dazzling dual stars—sodium and lithium.”
The new sodium battery technology we’re introducing this time is based on CTP 3.0 system integration technology, enabling a pure-electric range of over 400 km. Combined with an advanced BMS intelligent management strategy, it delivers precise control and ensures that the displayed range exactly matches the actual range. Even in extremely cold weather conditions, it can fully guarantee the vehicle’s range performance.
The energy density of the battery cells we’re introducing this time has reached 175 Wh/kg, representing the highest level currently available in the industry. Looking ahead, as the sodium-ion battery industry continues to develop, vehicles could achieve pure-electric ranges of 500 km and even 600 km—on par with today’s lithium-ion batteries. Moreover, when applied to range-extended or hybrid vehicles, sodium-ion batteries could deliver a pure-electric range of 300 to 400 km.
As is well known, the discharge power of a battery is closely related to ambient temperature. In today’s battery industry, once the temperature drops below 0°C, the battery’s discharge power will significantly decrease. However, the new sodium battery technology offers greater stability: even at -30°C, its discharge power is nearly three times higher than that of conventional lithium-iron batteries with the same capacity. Moreover, in extremely cold environments as low as -40°C, the sodium battery still maintains a capacity retention rate exceeding 90%. And even under the more severe conditions of -50°C, the sodium battery continues to deliver stable discharge performance. With this advanced technology, pure-electric vehicles will become increasingly popular in colder regions, offering not only an improved driving experience but also making a greater contribution to environmental protection.
In the field of safety, sodium-ion batteries have successfully passed extreme tests—including penetration by an electric drill and cutting through battery cells—demonstrating zero smoke, zero fire, and continued discharge capability even after being cut. This breakthrough thoroughly addresses the dual challenges faced by new-energy vehicles: reduced winter range and lingering safety concerns. Underlying this robust “all-scenario safety” technology moat is the solid support provided by Changan Automobile’s globally leading verification system. To validate mechanical hardware in real-world conditions, Changan has built the Western Automotive Test Center—the world’s leading automotive test facility, boasting Asia’s highest precision, China’s most comprehensive functionality, and the only one of its kind in western China. Covering 3,500 mu of land and with an investment exceeding 3 billion yuan, the center features test roads that surpass airport standards, including 14 dedicated test tracks and over 70 specialized road surfaces. Its annual testing mileage exceeds 20 million kilometers—equivalent to circling the Earth 500 times.
To validate its digital and intelligent capabilities, the country has established the nation’s only National Key Laboratory for Intelligent Vehicle Safety Technology and the world-leading “Tianxu Intelligent Testing Center.” This center boasts three globally unique features and three globally leading capabilities, covering over 400,000 virtual simulation test scenarios and enabling 24-hour uninterrupted global remote testing. The simulated driving mileage on Intelligent Driving Day exceeds 3.3 million kilometers, ensuring that by 2025, the Tianxu intelligent driver-assistance system will have accumulated over 200 million kilometers of safe driving.
By pioneering an industry-wide comprehensive safety system, opening up a new frontier in sodium-ion batteries, and embarking on global extreme testing, Changan Automobile is setting a new benchmark for intelligent safety through innovative breakthroughs. Looking ahead, as “Tianxu Intelligence” continues to evolve, Changan will uphold even higher safety standards to fulfill its heartfelt promise: “Bringing safety home—into every household’s warm lights.”
In summary, Changan Automobile’s newly unveiled sodium-based battery technology, jointly developed with CATL, represents a completely innovative endeavor. Not only does this technology address the issue of electric vehicle discharge power being affected by ambient temperature, but it also demonstrates Changan’s solid and steady progress in the new-energy sector through its practical actions. With comprehensive safety features, intelligent technologies, and cutting-edge innovations, Changan is delivering products that are not only more thoughtful and user-friendly but also truly practical for consumers. We sincerely hope to get our hands on the new sodium-battery models as soon as possible and experience firsthand the remarkable leap forward brought about by this technological breakthrough.
