"By 2022, intelligent thermal management technology will support the application of new energy vehicles in the environment of minus 30 degrees Celsius." On October 19, Hou Fushen, Deputy Secretary-General of the Society of Automotive Engineers of China, announced the 2022 annual meeting of the Society of Automotive Engineers of China in 2021. Technology trend report. The report is attended by nearly 400 experts from more than 120 authoritative units. It conducts predictive analysis on the development of cutting-edge technologies such as automobile electrification and interconnection that are of concern to all parties. It involves many domestic new energy batteries and intelligent interconnected chip industry chains. company.

　　High specific energy power battery and intelligent thermal management are expected to break through

"The improvement of safety technology will promote the application of high specific energy power batteries to vehicles." Hou Fushen said that with the development of new mass production technologies, high specific energy power batteries are an important technical means to increase the cruising range of electric vehicles. The power battery system is safe. Technology is the prerequisite for the application of high specific energy power batteries. The high specific energy power battery adopts high nickel cathode material and silicon carbon anode material, and it mainly faces the problems of power battery safety and cycle durability in terms of loading applications.

　　According to the 2022 automotive technology trend report, with the improvement of power battery system safety technology, in 2022, 300 watt-hour/kg power batteries will be the first to be installed in high-end vehicles. At present, the 300Wh/kg battery and system products of CATL, Guoxuan Hi-Tech, Rongbai Technology and other companies have completed technical development.

　　 The application of electric vehicles in low temperature environments is also expected to achieve breakthroughs. Hou Fushen introduced that intelligent thermal management is a key technology for new energy vehicles to break through the low-temperature environment. To improve the low-temperature adaptability of new energy vehicles requires breakthroughs in the low-temperature rapid heating technology of power batteries, integrated vehicle thermal management technology, low-temperature charging technology and other intelligent thermal management technologies. . The report of the Society of Automotive Engineers of China predicts that in 2022, intelligent thermal management technology will support the application of new energy vehicles in the environment of minus 30 degrees Celsius. Currently, domestic companies that develop this technology include BYD, CATL, Foton Motor, Weilai, etc. Junfeng has also invested heavily in the research and development industry.

　　 The scale of hydrogen and hybrid loading will be greatly increased

　　 Regarding the hydrogen vehicles that the market is concerned about, Hou Fushen said that life is the basic requirement for hydrogen fuel cell systems to achieve long-distance and heavy-duty applications. Hydrogen fuel cells are more suitable for medium and long-distance, medium and heavy-duty commercial vehicles, and have high service life requirements. The 10,000-hour service life can guarantee the mileage requirements of 300,000 to 400,000 kilometers.

　　The report analyzes that in 2022, under the promotion of the hydrogen fuel cell demonstration policy, hydrogen fuel cell systems with a lifespan of more than 10,000 hours will be used in long-distance and heavy-duty fields such as logistics, long-distance transportation, terminals, mines, and long-distance passenger transportation. Currently, the hydrogen fuel cell system developed by companies such as Yihuatong and Weichai Power has a life span of 10,000 hours.

　　The report also predicts that in addition to pure electric and hydrogen energy vehicles, the DHT hybrid power system as one of the new energy technology routes will double the scale of vehicle installation. Hou Fushen introduced that DHT hybrid technology can be applied to HEV and PHEV models and is an important technical path for passenger cars to save fuel and reduce carbon. The high efficiency and low fuel consumption balance can be achieved through the combination of high-efficiency hybrid dedicated engines and electric motors.

　　According to forecasts, in 2022, with the implementation of the research and development results of the DHT hybrid system of many car companies, more hybrid models will go on sale, and the DHT hybrid system is expected to reach 1.5 million sets of applications. Currently, BYD, Great Wall, Changan, Dongfeng Junfeng, Geely, BAIC and other companies have successively made breakthroughs in DHT hybrid technology. In 2022, related hybrid models will be launched on a large scale, and their sales will increase significantly.

　　 Large computing power vehicle-level computing chips will achieve mass production and loading

　　 In terms of intelligent networking, the report predicts that as the core component of the "brain" of highly autonomous vehicles, vehicle-grade computing chips above 100TOPS (processor computing power units) will be mass-produced and installed in 2022. Hou Fushen introduced that with the continuous improvement of the level of automobile intelligence and networking, the demand for computing power is becoming increasingly urgent. Currently, autonomous vehicle-level chips have formed batch applications for functions such as ADAS/smart cockpits, and large-power vehicle-level computing chips (single-chip computing power greater than 100 TOPS) are undergoing test trials.

The Chinese Society of Automotive Engineering predicts that by 2022, a number of single-chip products with more than 100 TOPS will enter the mass production pre-installation application, which will further provide the basis for the mass production of high-level autonomous vehicles. Currently, Huawei, Horizon and other companies.
