Recently, the joint venture cooperation between FGI and Qingdao Metro has landed, and FGI(Qingdao) Transportation Technology Co., Ltd. has completed the industrial and commercial registration procedures. The main business is the promotion and application of rail transit regenerative braking energy absorption device and related supporting products, bidirectional converter device, energy storage device and emergency power supply, flywheel energy storage device.

FGI has been deeply engaged in the rail transit industry for more than ten years, and proposed the locomotive braking energy feedback absorption solution earlier in China. The regenerative braking energy absorption device developed and produced by FGI is based on the four-quadrant elevator frequency converter mature in the traditional industrial control field, and was developed for the localization of the on-board resistance absorption device of Chongqing Metro. It has been applied in nearly 30 main subway lines, led the drafting and examination of the national product standards in 2019, built the Shandong Provincial Laboratory of rail transit traction and control engineering, and the industry-leading technology iteration product bidirectional converter device in 2023, the first time in China to completely replace traction rectifier, put into use in Lijiang, Yunnan Province, once again leading the development of the industry.

Qingdao rail transit equipment is a national advanced manufacturing industry cluster and a source of technological innovation in the field of rail transit with global influence. The establishment of FGI(Qingdao) Transportation Technology Co., Ltd. in Qingdao is a new measure by FGI to fully develop and expand the rail transit equipment industry chain, not to deliberately pursue to improve the local allocation rate, but to promote the construction of collaborative innovation ecology by relevant parties in the industry, accelerate the progress to the middle and high-end value chain, and lay out the industrial highland.

Traction power supply technology is one of the core technologies of rail transit equipment, which is a highly integrated mechatronics system technology. In the future, FGI plans to make new breakthroughs in the innovation of the "product +" model, and is committed to providing high-end intelligent power supply equipment with global competitiveness for rail transit and other fields, and intelligent solutions for the whole life cycle, creating brand internationalization, individual specialization, system integration, intelligent operation and maintenance, and high-end quality of digital operation, and further promoting the localization of core equipment.
