News Agency NewsOn January 30, GAC Aion's Ruipai Intelligent Ecological Electric Drive Factory was officially completed and put into operation, and the new breakthrough of Quark electric drive - M25 super electric drive mass production landed. So far, GAC Aion has achieved comprehensive self-research and self-production in the field of new energy and electric vehicles, and realized an independent and controllable industrial chain layout. It is worth mentioning that the M25 super electric drive will also be the first to be installed in Haobo brand models.
It is understood that the total investment of Ruipai intelligent ecological electric drive factory is 21600 million yuan, covering an area of 1040,000 square meters, focusing on the independent research and development and industrialization of IDU electric drive system and electronic control, to achieve the integration of independent electric drive and electronic control research and development, intelligent manufacturing, sales and service. It is expected to achieve an annual output of 400,000 sets of idu electric drive system assemblies and 100,000 sets of GMC hybrid electric coupling system motors and electronic control systems by 2025.
GAC Aion's RTS super process includes ultra-high-precision shaft tooth grinding process, high-speed wire forming and winding making process, ultra-flexible flat wire assembly process, and ultra-high-precision rotor dynamic balancing process. Among them, the ultra-high-precision shaft tooth grinding process can realize the mirror grinding of the gear of the low-vibration motor at the highest speed, and the tooth surface roughness can reach up to Ra01μm。At the same time, a series of advanced processes such as high-speed wire forming, winding making, ultra-flexible flat wire assembly, and ultra-high-precision rotor dynamic balancing provide a solid guarantee for product performance and quality, and help reduce production costs and cycles.
In addition, the newly completed Ruipai intelligent ecological electric drive factory also has industry benchmarking significance in five aspects: quality, flexible production, intelligence, efficiency and low carbon. In order to meet the quality requirements of aviation-grade, Ruipai Intelligent Ecological Electric Drive Factory realizes high-quality and high-stability electric drive production through ultra-high-precision process design and quality monitoring and management of the whole process, and also makes it the world's first aviation-grade quality benchmark electric drive factory.
In terms of flexible production, Ruipai Intelligent Ecological Electric Drive Factory has achieved the world's first ultra-high flexible and automated electric drive manufacturing through comprehensive automation, standardization, modular design, and intelligent program control. In the field of intelligence, it adheres to the concept of GAC's lean production mode, and with the help of the intelligent factory operation platform, it has built a world-leading intelligent ecological electric drive factory through intelligent deployment, intelligent monitoring and intelligent decision-making.
In terms of efficiency improvement, through the extremely efficient use of people, equipment, time and space, the loss of the production value chain is fully reduced, which is 15% lower than the industry level, and the world's leading electric drive factory with extreme efficiency is created. In terms of green environmental protection, we will build the world's leading low-carbon and environmentally friendly green factories through three major measures: green electricity, energy conservation and emission reduction.
With a speed of 22,000 rpm, the M25 super electric drive is also the world's first high-speed motor to achieve mass production. What's more, the M25 super electric drive has been tested for durability and reliability for millions of kilometers to ensure smooth operation at high speeds. The 79% slot filling rate of the M25 super electric drive is only half of the mainstream products, providing more space for the overall design and layout of the vehicle. The power density is up to 12kW kg, which is double the industry average.
In addition, the M25 super electric drive is also the world's first mass-produced ultra-high voltage 900V electric drive, independent research and development and design of high-voltage silicon carbide module, copper wire direct connection DTS technology and all-silver sintering process can achieve a 30% reduction in volume, a 40% reduction in stray inductance, and a 25% increase in current; At the same time, the electric drive also improves the efficiency of the electronic control algorithm, the motor design, and the light-load drive train, reaching the world's leading 925% operating efficiency.
