The Theme of the 12th TM Syposium China-Ice, (P) HEV&EV TRANSMISSIONS & DRIVES: How to select and develop the electric drive system of the future?
Driven by new energy vehicle policies and regulations and market competition, along the main line of improving efficiency, power density and cost, electric vehicle drive systems are accelerating innovation and showing great room for development, where the gradual increase in power density may eventually leave the engine compartment empty and realize electric chassis platforming. In addition, NVH optimization, reliability and functional safety are also key technical indicators of the electric drive system, and there is a lot of room for improvement in the future.
Drive system technology innovation from multiple levels, showing a diversity of technical development lines. For example, in the system integration level, three in one, multi-integration and more in-depth integration based on innovative configuration has become the most important technology development direction. This is followed by high-speed, high-voltage and multi-stopping, all of which are also important technology trends. At the subsystem level, the application of SiC controllers will make an important contribution to improving the efficiency and cost of the overall power system and especially the power density. Motors, thermal management and lubrication also all have great potential for development. At a higher level, the adoption of a modular platform strategy for drive systems can effectively increase production scale and spread R&D and manufacturing costs.
However, each of the above directions of technological innovation are facing many technical and industrialization challenges to continue to break through, the development rate will vary. Faced with the rapid development of electric drive technology and the fierce technology race among enterprises, enterprises need to grasp the new technology trends timely and fully, accelerate the improvement of R&D capability, strengthen open cooperation, and come out of their own innovation path.
This year's TMC will cover most of the above-mentioned seminars on innovative technologies and strategies. More than 10 companies such as GAC, Toyota, BMW, Bosch, Valeo, BorgWarner, Zhu Gear, IAV, Ricardo, Nomex, Ensco, Toyokawa Power, Total, etc. will bring presentations on innovative technologies and solutions for electric vehicle transmission and drive systems, covering modular platform strategy and development, multi-gear and innovative integrated electric drive system concept and development, system integration development of high quality electric axles and Solutions for high-speed transmission systems, etc. A high-level interactive forum will be organized to discuss the main innovative directions and challenges of electric drives.
