Chapter four Accelerate the electric transformation! The 13th International Symposium on Auto

Published on2020-04-25

  

[EV Vision Report] At present, China and major developed countries have successively put forward the development vision of "carbon neutrality", and international automobile companies have successively put forward their own "carbon footprint" plans. The concerted action of "carbon neutrality" by the international community will further accelerate the electric transformation of the automobile industry. The 13th International Symposium on Automobile Transmission and Drive Technology was grandly opened in Shanghai Baohua Marriott Hotel on July 8th, 2021. 

There are 60 cutting-edge and core technical speeches and two high-level interactive forums on hot issues in this conference. The latest technologies and products of nearly 80 well-known powertrain and parts companies will be displayed in the same exhibition. More than 1,000  representatives from complete vehicle, transmission and drive assembly, parts and engineering consulting companies will attend and visit the exhibition. Electric power is the technological change of automobile energy and drive system,which leads the global automobile industry to transform and upgrade to new energy vehicles, and becomes the symbol of the core competitiveness of the automobile industry.At the same time, electric drive will lead to the systematic reform of  automobile power electronic architecture and intelligent control system. In the era when the automobile industry began to move towards full electrification and intelligence,TMC ushered in the largest grand meeting, offering a large number of innovative technical reports and exhibitions on electrification and intelligence of power systems to the industry. On the basis of the original topic,this session will deepen the discussion on electrification of power system and expand to the digital field. For example: deep electrification of hybrid power, deep integration

of electric drive system, domain controller of power system and chassis,infrastructure, integration and OTA of control software, application of big data, AI and interconnection technology in fine optimization of power system, intelligent control and health management, drive motor and power electronic devices for improving power system efficiency,power density and cost, and modular platform with deep integration of functions, etc. At the opening ceremony, Professor Ge Anlin, winner of the "Outstanding Contribution Award" of the International Symposium on Automobile Transmission and Drive Technology, was presented with an award. Professor Ge was a professor at Jilin University, a doctoral supervisor, director of transmission center.

 

he was awarded the Memorial Medal of the Central Committee of the Communist Party of China, the State Council and the Central Military Commission. Zhang Jinhua, executive vice president and secretary general of China Automotive Engineering Society, presented the award, and Gao Zhenhai, dean of Automotive Engineering College of Jilin University and director of State Key Laboratory of Automobile Simulation and Control, presented the award on behalf of Professor Ge.

 In the keynote speech session, Zhang Xuming, deputy secretary-general of China Automotive Engineering Society, was the host, and on behalf of the sponsor, China Automotive Engineering Society, expressed sincere greetings and heartfelt thanks to all the experts, delegates and media friends for their arrival. He mentioned that full electrification is the electrification of the drive system. As the core components of all kinds of new energy vehicles, the drive motor and its control system are the key to realize the conversion of mechanical energy and electric energy for new energy vehicles.

At the beginning of the keynote speech, Wang Ruiping, senior vice president of Zhejiang Geely Automobile Group and chairman of SCP (Passenger Car Powertrain Professional Committee), delivered the keynote report "Thoughts on the transformation of carbon-neutral powertrain in peak carbon dioxide emissions". He explained the trend of electrification transformation and upgrading of traditional travel power in the next 10-15 years under the background of the national environmental strategy of peak carbon dioxide emissions and carbon neutrality, and introduced.

 

Wang Ruiping, Senior Vice President of Zhejiang Geely Automobile Group and Chairman of Passenger Car Powertrain Professional Committee (SCP) 

Next, Qi Hongzhong, Chief Technical Director of Automotive Engineering Research Institute of Guangzhou Automobile Group and Deputy Director of Powertrain Technology R&D Center, gave a video speech, bringing a wonderful report titled "Green Engine Technology-GAC High-efficiency and Low-carbon Hybrid

Solution". He pointed out that under the background of peak carbon dioxide emissions, carbon neutrality and increasingly stringent fuel consumption regulations and policies, it is an inevitable trend for traditional fuel vehicles to be hybrid. GAC has also formulated a clear hybrid strategy and countermeasures,built a hybrid platform based on Moment Wave Power, and developed hybrid products with many performance advantages such as carbon reduction, quality, economy, speed, quietness and smoothness. Focus on promoting the development of special hybrid engine (DHE) and special hybrid transmission (DHT), in which double-motor series-parallel DHT has completely independent intellectual property rights, which provides an effective solution for domestic double-motor DHT.

Qi Hongzhong, Chief Technical Director of Automotive Engineering Research Institute of Guangzhou Automobile Group and Deputy Director of Powertrain Technology Research and Development Center   Next,Yang Wentao, senior technical manager of HSR/E2 platform integration of Shanghai Automobile Transmission Co., Ltd., gave a wonderful speech. "The development trend and core characteristics of electric drive" realized the high power density (miniaturization) of the system through (ultra) high-speed motor and gear box with large speed ratio, and the high power density (miniaturization) of the system provided the possibility for high integration and multi-gear. No matter how the electric drive system develops, its NVH characteristics will occupy the coreposition. This report deeply discusses the influence of various components of electric drive system on NVH of the whole vehicle, puts forward corresponding

solutions and provides relevant examples.

High-level interactive guests:

Zhang Shimin, chief engineer of New Energy and Powertrain Center of Dongfeng Motor Group Co., Ltd.

Liu Yintong, chief designer of hybrid power system of Chongqing Changan Automobile Co., Ltd.

Zheng Lipeng, co-chairman of Honeycomb Yichuang Technology Co., Ltd. Wang Jian, Executive Director of Electric Drive Business Department of Shanghai Jieneng Automobile Technology Co., Ltd.
