New energy vehicle busbars are essential conductive components used in high-voltage electrical systems of new energy vehicles. Made from high-purity copper or aluminum as conductive materials through precise forming and insulation coating processes, they possess various advantages such as high current-carrying capacity, low impedance loss, excellent heat dissipation, a compact and reliable structure, and strong mechanical resistance. As crucial foundational parts that ensure overall vehicle power transmission efficiency and electrical safety, busbars are extensively applied in core three-electric systems like power battery packs, motor controllers, high-voltage distribution units, and on-board chargers, serving all types of new energy vehicles including passenger cars, commercial vehicles, and special operation vehicles.
Currently, the development of China’s NEV busbar industry is influenced by several factors. The global NEV industrial chain is shifting more towards the Chinese mainland, and the growing production capacity of domestic vehicles and power batteries has led to rapid demand for high-voltage busbars. Government policies promoting independent control of core NEV components have accelerated domestic substitution, enabling local manufacturers to break the long-term technological monopoly held by foreign companies in high-end busbar areas. The widespread adoption of 800V high-voltage fast charging technology and highly integrated battery technologies such as CTP and CTC has promoted busbar products to become more integrated, lightweight, and reliable, resulting in a steady increase in value per vehicle. Additionally, the rapid growth of emerging industries such as energy storage stations, the low-altitude economy, and the electrification of construction machinery has created new opportunities for the industry. Overall, the large-scale expansion of the NEV industry, technological upgrades driving value increases, deeper implementation of domestic substitution policies, and expanding demand in emerging fields are the main factors contributing to the continuous growth of China’s NEV busbar market.
