Heju Precision Participates in Drafting the “Technical Specifications for High-Voltage Connector Terminals for New Energy Vehicles”
The group standard titled “Technical Specifications for High-Voltage Connector Terminals for New Energy Vehicles” (Standard No.: T/CASME 2161-2026)—proposed and administered by the China Association of Small and Medium Commercial Enterprises, with Heju Precision participating in its drafting—has been officially released and implemented following public notice on the National Group Standard Information Platform. This marks another significant achievement for Heju Precision, reflecting its deep commitment to the design and manufacturing of precision connector terminals and its contribution to the standardized, high-quality development of the industry.
With the rapid development of the new energy vehicle industry, requirements for high-voltage connection systems—specifically regarding terminal current-carrying capacity, temperature rise control, mating durability, and vibration reliability—have become increasingly stringent. However, the long-standing absence of unified, detailed technical specifications for terminals has led to issues such as inconsistent standards and poor compatibility among upstream and downstream enterprises during component selection, testing, and acceptance.
Against this industry backdrop, the group standard *Technical Specifications for High-Voltage Connector Terminals for New Energy Vehicles* was introduced to meet emerging needs. The standard comprehensively defines specifications—including coding and dimensions, material selection, core technical parameters, test methods, and inspection rules—as well as requirements for marking, packaging, transportation, and storage. It provides an authoritative and unified technical basis for the R&D, intelligent manufacturing, quality inspection, and market delivery of terminal products within the industry.
As a key drafting organization for this standard, Heju Precision leveraged its extensive technical expertise in the R&D and manufacturing of new energy vehicle (NEV) connection terminals. By integrating practical experience gained from serving mainstream NEV manufacturers and top-tier suppliers into every stage of the drafting process, the company ensured that the standard aligns with actual manufacturing realities and is highly practical for implementation.
Participation in the formulation of industry standards is not only an industry acknowledgment of Heju Precision’s technical prowess and professional expertise, but also a tangible demonstration of the company’s proactive commitment to driving industry progress.
Looking ahead, Heju Precision will continue to focus on the trends of miniaturization, integration, and intelligentization in high-voltage connection systems. By actively participating in the development and revision of national and industry standards—and translating frontline manufacturing experience into shareable technical specifications—the company will continue to contribute “Heju Solutions” toward ensuring the security and controllability of China’s new energy vehicle supply chain and enhancing its global competitiveness.
