New energy vehicle technology has made progress -Lithium - Ion Battery Equipment
The new energy vehicle market has achieved unprecedented development. Correspondingly, the new energy vehicle technology has also performed well. From the perspective of the entire electric vehicle system, the overall driving range has been improved, and the energy consumption per 100 kilometers is also much lower than in the past. In addition, great progress has been made in many aspects such as battery safety, energy recovery, and lightweight. So, in the past year, which industrial technologies have attracted our attention?
Battery safety has improved
This year, some companies and universities have analyzed the results of power batteries after being hit, punctured and burned from their areas of expertise, so as to improve the safety of the entire vehicle. Xie Man, an associate professor of Beijing Institute of Technology, proposed a method to improve the safety of power batteries by using additives and other means from a chemical perspective, which has been widely valued by enterprises. A person in charge of the company told reporters that if the safety of batteries can be improved through low-cost and simple and effective methods, it will be of great benefit to reducing battery costs and popularizing new energy vehicles.(Lithium - Ion Battery Equipment)
Zhao Hui, vice president of Changan Automobile Engineering Research Institute, is also engaged in research on battery safety. Zhao Hui told reporters that for the power battery, by testing the reaction of the power battery after being squeezed, punctured and other injuries in different directions, it can guide the power battery to be packaged into groups more safely and efficiently. Zhao Hui said: "Through research, Changan Automobile has mastered the characteristics of many types of power batteries that are damaged in different directions. This basic research and development can deeply tap the potential of battery safety and improve vehicle safety."
The advantages of the motor are highlighted
In the first few years of the new energy vehicle industry, many companies in the industry have devoted their energy to batteries, which makes the battery's position in the "three powers" particularly important. This kind of "one-dominant" situation has improved, and the status of motors and electronic controls has gradually increased, and more car companies have begun to treat "three powers" as a system. Cai Wei, founder and chief technology officer of Jingjin Electric, pointed out that the "three powers" of electric vehicles are a whole, not the technical problems of the battery are solved, the problems of the motor and electronic control can be solved easily, and the "three powers" should be regarded as one Look at it as a whole. Cai Wei exemplified that domestic manufacturers have no problem with only making motors. If they integrate parts such as clutches and gears with motors, compared with internationally renowned suppliers, domestic manufacturers will show their weaknesses in system integration capabilities. Cai Wei believes that special financial support for electric drive system and key component platform construction and industry should be increased. At present, domestic new energy vehicle supporting motors can basically achieve independent production, but there is still room for improvement in key parameters such as power density, speed range and constant power zone width.
Car companies love to "play" with electronic control
As the "electronic control" in the "three powers", it used to be the most easily overlooked part of the core technology. This year, many domestic car companies have made the most progress in "electronic control". For example, Yutong's rui control technology realizes high system integration, real-time judgment of vehicle status, and matching power combination scheme. Ren Yong, general manager of Changan New Energy, told reporters that although Changan Automobile's Eado EV battery is provided by Tianneng Group, the battery pack packaging technology and vehicle electronic control technology are developed by Changan Automobile itself and have intellectual property rights. In the future, Changan Automobile Co., Ltd. The car will continue to conduct in-depth research and development in the field of electronic control to maximize the potential of battery motors. At present, because OEMs are often not involved in the production and manufacture of key components such as batteries and motors, most car companies choose to make efforts in the field of electronic control. This is also the reason why domestic car companies have made great progress in the field of "electronic control" this year. s reason.
