Product Introduction
The Cap and Contact for Battery Power and Auxiliary Fuses is specifically designed for the high-voltage power systems of new energy vehicles. It precisely adapts to various fuses in the main and auxiliary circuits of the power battery pack, fulfilling three key functions: current transmission, sealing protection, and circuit protection. It can stably conduct high on-board current, isolate contaminants such as moisture and dust, prevent circuit abnormalities, and efficiently support overload and short-circuit protection of the vehicle's high-voltage system. It is suitable for harsh operating conditions such as 800V high-voltage fast charging and high-frequency vibration in vehicles, and is compatible with core high-voltage components such as PDUs, DC fast charging ports, and MCUs, providing core supporting components for the safe and efficient operation of the power system of new energy vehicles.
Core manufacturing process
Precision Stamping
We select high-quality copper materials that meet standards and use high-precision molds to complete the stamping process. This precise machining ensures the accurate processing of the cap and contact structures. Strict control over positioning accuracy and comprehensive dimensional and appearance inspections are performed throughout the process to eliminate deviations and distortions, providing qualified semi-finished Cap and Contact for Battery Pack Fuse for subsequent processes.
Multi-faceted Welding
Before welding, the relevant parts of the Cap and Contact for EV Charging Fuse undergo fine pretreatment such as degreasing and grinding to remove impurities and oxide layers and avoid the risk of incomplete welding. During welding, multiple processes are adapted and parameters are precisely controlled to balance efficiency and quality. After welding, the appearance, strength and conductivity are inspected to ensure that the product is firmly connected and has stable conductivity, making it suitable for high-voltage vehicle conditions.
Comprehensive Quality Control
We have established a comprehensive quality control system covering raw material entry, process inspections, and final product inspection. We focus on verifying core Copper Cap Contact for Eaton Bussmann Series EV Fuses indicators, adding specialized tests for critical processes, and maintaining batch records for traceability. This ensures that products meet automotive standards and relevant quality system requirements.
