On the 29th, the Chinese Society of Automotive Engineers released the "Top 10 Technology Trends for Chinese Automobiles in 2027". This consensus building industry "barometer" suggests that next year, car batteries will be stronger, chips will be more autonomous, "hard technology" will be used more, and traffic congestion will be reduced.
In the field of electric vehicles, electric vehicles not only need to be charged, but also discharged to the power grid. By 2027, more than 100000 electric vehicles with discharge function will be added, and the daily power regulation can reach millions of kilowatts. This type of electric vehicle can discharge to the grid during peak electricity consumption and charge during low electricity consumption, bringing considerable discharge and conduction benefits. At the same time, more powerful and safer batteries will enter the pilot stage - by 2027, the "next generation power battery" solid-state battery with longer range and safer than liquid lithium batteries, with a single energy density of 400Wh/kg, will enter the pilot stage, and leading companies will conduct vehicle validation first.
In the field of automotive chips and in car artificial intelligence, multiple high-end automotive microcontroller chips will be mass-produced and delivered, and core control domain chips such as power and chassis may be localized; The large model technology used in cars will be more mature, able to stably support continuous dialogue and in car visual perception, while improving interaction experience and protecting data privacy; The integrated vehicle motion control technology originally used for high-end car models is expected to expand to more car models, improving sports safety, handling performance, and driving comfort.
In terms of reducing traffic congestion and improving driving safety, the integrated vehicle road cloud assisted driving will work together with in vehicle assisted driving algorithms to comprehensively improve driving safety, traffic efficiency, and driving comfort. It can achieve a 66.7% reduction in collision risk, an 8.29% reduction in vehicle operating energy consumption, and a 12% reduction in queue congestion time at intersections.
In the field of "hard technology", by 2027, magnesium alloy integrated forming technology will penetrate from small components to large structural components, and achieve mass production in areas such as rear floor and tailgate - this technology can reduce the weight of cars by about 20%; A key breakthrough has been made in the development of dispersed wheel hubs, which has been verified through engineering to increase speed. This not only frees up about 20% of the chassis space, making the interior space larger, but also reduces energy loss in the transmission process and improves system transmission efficiency; Metal 3D printing technology will have breakthroughs in industrial applications, and is expected to be applied to mid-range car models in the next 3 to 5 years, reducing the weight of complex structural components by over 30%, while simultaneously improving stiffness, strength, durability, and collision safety performance.
