On January 30, GAC Aion's Ruipai Intelligent Ecological Electric Drive Plant was officially completed and put into operation, and the Quark electric drive independently developed by GAC - M25 super electric drive was officially mass-produced.
According to GAC Aion's official disclosure, the total investment of Ruipai Intelligent Ecological Electric Drive Plant 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.
In the Ruipai electric drive plant, GAC Aion adopts the RTS super process, including ultra-high-precision shaft tooth grinding process, high-speed wire forming and winding manufacturing 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 gears of low-vibration motors at the world's highest speed, and the tooth roughness can reach up to Ra01μm。In addition, 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 are also adopted, which provide a solid guarantee for product performance and quality, help reduce production costs and cycles, and provide a strong guarantee for the final realization of mass production.
The M25 super electric drive, the first mass-produced electric drive assembly product put into production at the Ruipai electric drive plant, will be the first to be installed in Haobo brand models. The maximum speed of the motor is 22000rpm, and the system efficiency is 925%, it also supports 900V ultra-high voltage fast charging, and has a motor power density of 12kW kg, which is the first echelon of current mass-produced products.
Previously, on December 12 last year, GAC Aion's Inpai Battery Intelligent Ecological Factory was officially completed and put into operation. At the same time, GAC Aion's self-developed P58 microcrystalline super energy battery was also released. The plant can achieve a production capacity of 6GWh in the first phase, and will complete the introduction of a 36GWh production line in the later stage, which can meet the demand for 600,000 new energy vehicle power batteries at the same time.
The official completion and operation of the Ruipai intelligent ecological electric drive plant means that GAC Aion has achieved a comprehensive independent and controllable first-chain layout in the field of core components of the new energy three-electric system.
Previously, in 2022, GAC's powertrain company Julang Power has released GMC2The 0-speed two-speed direct-drive DHT dual-motor hybrid system is mass-produced and installed in the HEV gasoline-electric hybrid version of the Shadow Leopard, Yingku, and Trumpchi GS8. The completion and commissioning of the Ruipai electric drive plant will enable GAC's own brand passenger cars to better respond to market demand, reduce costs, and provide consumers with more high-quality products with high quality and low prices.
