Product Description
As a professional manufacturer of EV battery terminals, we supply high-quality components for automotive battery packs and EV batteries. Our positive battery terminal is designed for corrosion resistance, good weldability, and high conductivity, for secure and efficient connections. The negative battery terminal has up to 99.6% conductivity, strong anti-interference ability, and a long lifespan, for stable power transmission under harsh conditions.
Our positive battery terminal is designed for corrosion resistance, good weldability, and high conductivity, for secure and efficient connections. The negative battery terminal has up to 99.6% conductivity, strong anti-interference ability, and a long lifespan, for stable power transmission under harsh conditions.
Every terminal is made by a precise process, including raw material preparation, cold forging, cleaning, passivation, inspection, and packaging, to ensure the quality and performance are consistent.
Proven and customizable, our positive and negative battery terminals are trusted by top automotive and EV battery pack manufacturers worldwide.
The production process of the terminal encompasses three core stages: cold heading, precision machining, and post-processing cleaning. Each stage is built around high precision and a high degree of automation to ensure consistent product performance and quality. The terminal offers excellent conductivity, tensile strength, and toughness, with conductivity reaching up to 100% IACS, tensile strength exceeding 230 MPa, and elongation greater than 8%, achieving an optimal balance of strength and ductility. Backed by a fully automated production system, this terminal is widely used in new energy vehicle relay applications, meeting stringent requirements for highly reliable, high-precision connection components.
Cold heading forming: The 6-die, 6-station cold heading process is employed. Through multi-station progressive cold forging, the initial forming of the terminal is completed in a single operation, ensuring a dense billet structure and high dimensional accuracy, which lays a solid foundation for subsequent machining.
Precision machining: Using automatic dual-spindle lathes and Swiss-type lathes, we achieve high-precision machining with dimensional accuracy up to 0.01 mm, ensuring tight control of critical product dimensions and geometry. The machined surfaces can reach a surface roughness of Ra 0.2 μm, effectively reducing surface defects and enhancing the product's electrical conductivity.
Post-processing and inspection: The line is equipped with fully automated cleaning systems that efficiently remove residual oil, chips, and other contaminants generated during machining. Combined with CCD visual inspection technology, it enables comprehensive inspection of product appearance, dimensions, and other critical attributes. In addition, a proprietary large-scale data acquisition system is used to monitor and analyze key quantitative parameters—such as oxidation levels—in real time, ensuring that every product meets stringent quality standards.
The main body is made from high-conductivity pure copper or tellurium copper, delivering excellent electrical conductivity, corrosion resistance, and fatigue performance—well-suited for high-voltage, high-current operating conditions in new energy vehicles and energy storage systems.
