Product Description
-
Reduced wiring distance, simplified structure, and lower costs. Its core value lies in replacing traditional wiring harnesses, significantly shortening connection paths, simplifying the internal structure of battery modules, and substantially reducing material and installation costs.
-
Flexible bending without damage, excellent space adaptability. Specially treated flexible copper busbars offer outstanding flexibility, supporting large-angle, multi-direction bending to easily adapt to compact or irregular spaces, completely eliminating the risk of conductor damage caused by bending stress.
-
Flexible customization for perfect matching. Parameters such as shape, size, and current-carrying capacity can be precisely customized according to the battery module layout and electrical requirements, achieving optimal space utilization and electrical performance.
-
Integrated molding for robust sealing, ensuring safety and reliability. Key connection components adopt an integrated injection molding process, resulting in a sturdy and durable structure with excellent waterproof, dustproof, and anti-corrosion properties, guaranteeing the long-term stable operation of energy storage systems in harsh environments.
Sanco provides one-stop manufacturing solutions covering the entire process from product design, mold development and production, stamping and CNC machining, plating and spraying, to final assembly and inspection.
Our R&D team of 200 experts and professional laboratories enable us to independently execute product structure design, CAE simulation analysis, performance validation, and in-house mold design and manufacturing. Equipped with specialized mold technicians and advanced machinery (including slow wire cutting, fast wire cutting, medium wire cutting, and CNC machines achieving machining accuracy up to 0.02mm), we produce terminals through cold heading or CNC processes and complete plating in-house. Plastic raw materials are thermally baked and injection molded with terminals, followed by assembly via both manual and automated equipment for final shipment. With our professional production and quality assurance teams, we ensure efficient and precise execution at every stage..
Sanco testing center is equipped with standard test site, professional testing team, more than 100 sets of advanced testing equipment, can scientifically operate according to ISO/IEC/UL/GB/GJB and other laboratory accreditation standards, establish a sound quality management system.
In March 2021, it was officially recognized by the China National Accreditation Service for Conformity Assessment (CNAS). It is conducive to improving its own management and technical capabilities, providing a full range of quality plans for products, and increasing customers' trust in Sanco and core market competitiveness.
Energy Storage Connectors with Flexible Busbar have become a critical and increasingly mainstream technical solution in energy storage systems, particularly at the battery module and pack levels. Compared to traditional rigid busbars or standard cable connections, flexible busbar connections offer significant advantages in reliability, safety, and performance: they provide exceptional resistance to vibration and fatigue, greatly enhancing long-term stability in dynamic environments; meanwhile, they deliver higher current-carrying capacity and lower impedance/resistance, effectively reducing energy loss and thermal risks. Additionally, this battery connector design optimizes spatial layout and simplifies the assembly process.
