The Laminated Busbar Industry Ushers in New Development Opportunities.
Apr 03, 2025
Against the background of the accelerated development of new energy vehicles and high-end equipment manufacturing industries, laminated busbars, as the core connection components of power electronic systems, are experiencing rapid growth in market demand. Recently, new progress has been made in the construction of key projects in many places. The industry's technological innovation and capacity expansion have been promoted simultaneously, injecting new momentum into the industry's high-quality development.
According to industry research data, the global electric vehicle Laminated Copper BusBar market has steadily grown. In 2023, the market sales will reach 6.5 billion yuan, and it is expected to exceed the 10 billion yuan mark by 2030, with an annual compound growth rate of 6.5%. As the world's largest new energy vehicle production and consumption market, the Chinese market has a particularly significant growth rate in laminated busbar demand. In 2022, the domestic market size exceeded 80 billion yuan. With the continuous improvement of the penetration rate of new energy vehicles and the technological upgrades in energy storage, rail transit, and other fields, the core position of laminated busbars in high-voltage connection systems has been further highlighted, and the market space has continued to expand.
Industry application scenarios are also constantly expanding. With its advantages of low impedance, anti-interference, and compact structure, Laminated Copper Bars have been widely used in the electric drive systems of battery electric vehicles and plug-in hybrid vehicles, as well as in industrial frequency conversion, energy, and power. Especially in the high-voltage distribution system of new energy vehicles, it can effectively improve the efficiency of power transmission, ensure system stability, and become a key component of the vehicle electrical architecture.
Technological breakthroughs and process innovations have become the core competitiveness of industry development. Through the new process independently developed by a certain enterprise, the Laminated Busbar Connectors products are significantly better than traditional solutions in terms of sealing, life, and other performance indicators, while achieving cost optimization of more than 20%. The company is promoting a headquarters base project with a total investment of more than 1 billion yuan, planning to build an intelligent production line. After reaching full production, the annual production capacity is expected to exceed 200 million pieces, and the annual output value will reach 2.5 billion yuan, further consolidating its leading position in the field of electrical connection components.
The regional industrial cluster effect is also gradually emerging. For example, a certain intelligent manufacturing industrial park in Suzhou is focusing on high-end equipment, new energy, and other fields, attracting many leading companies in the industry to settle in. Among them, the Laminated BusBar Copper without Tin Plated production project covers a total area of about 42,000 square meters. It is planned to build high-standard factory buildings and supporting facilities. It is expected to be completed and put into production in the third quarter of 2024. After production, it will form an annual production capacity of 200 million pieces/sets of new energy vehicle busbars, helping the region to build a complete new energy industry chain ecosystem.
Local governments promote the transformation of the laminated busbar industry to high-end and intelligent through policy support and capital guidance. Taking Shifeng District as an example, the local government encourages enterprises to increase R&D investment through the "leading enterprise + small and medium-sized enterprises" collaborative innovation model. With the technical support of a leading enterprise in the field of rail transit, a certain enterprise successfully transformed to produce Laminated Bus Bar for High Current Inverters, with the proportion of R&D investment increased to 14%, the product line covering multiple high-end application scenarios, and the order volume doubled.
With the release of market demand, the industry competition pattern is also constantly optimizing. Through technology accumulation and capacity expansion, domestic enterprises have gradually broken through the market barriers of international brands and significantly improved their position in the global supply chain. At the same time, capital's attention to the industry continues to heat up, and many billion-level investment projects have been implemented, accelerating the integration of the industry and technology iteration.
Looking to the future, laminated BusBar for Switch will continue to make breakthroughs in material innovation (such as copper-aluminum composite conductors) and structural design (modular integration) to meet the needs of lightweight and high power density of new energy vehicles. At the same time, with the advancement of the "dual carbon" goals, the industry will accelerate the transformation to green manufacturing, reduce energy consumption through process optimization, and improve the product recycling rate.
industry is in a period of dual dividends in technology and market. Enterprises need to continue to increase R&D investment and strengthen industrial chain collaboration to cope with global market competition. With the completion and commissioning of more high-quality projects, my country is expected to form an internationally competitive industrial cluster in the field of laminated busbars, providing stronger support for the development of the new energy industry.
