The deep integration of China's connector industry with the new energy industry
”
The deep integration of China's connector industry with the new energy industry is centered around high-voltage connectors, high-speed signal connections, and flexible soft connections, comprehensively supporting the development of key sectors such as new energy vehicles, energy storage, and hydrogen energy. In the field of new energy vehicles, the popularization of 800V high-voltage platforms has driven the current capacity of connectors to increase to 800A and the power to 800kW. The 'High-Voltage Connection System for Electric Vehicles' (GB/T 37133-2025) issued by the Ministry of Industry and Information Technology in 2025 clearly outlines 16 stringent testing standards for contact resistance classification, high-temperature durability, electromagnetic shielding, etc., significantly enhancing system safety and reliability. The market size of high-voltage connectors is expected to reach 34.4 billion yuan in 2025, accounting for over 55% of the total automotive connector market, and the market size of core power transmission components (including wiring harnesses and connectors) will exceed 50.8 billion yuan. Leading enterprises such as Yilian Technology have shipped over 100 million pieces of CCS battery cell connection components, and Wenyi Electric has independently developed modified nylon and oxygen-free copper soft connection processes with hydrogen embrittlement resistance meeting ISO 17081 standards, deeply binding with supply chains such as CATL and Ideal Automobile. The integration trend is extending from automobiles to energy storage electrolytic cells, high-density cabinets in data centers, and rail transit. The market size of flexible soft connections is expected to exceed 23 billion yuan in 2026, with low-carbon materials and AI intelligent monitoring becoming new growth poles.
