Structure and Application Copper foil soft connection is made up of multiple pieces of T2 purple copper foil stacked and welded to both ends. Drilling can be carried out according to customer requirements. Molecular diffusion welding is a precision welding technology that promotes mutual diffusion and bonding between atoms of a workpiece under high temperature and pressure conditions. A high-strength joint is formed while maintaining no visible deformation of the workpiece.
Therefore, copper foil soft connection is an excellent electrical conductor and is usually used in related industries such as new energy vehicles, wind power generation, photovoltaic energy storage, electric locomotives, and complete transmission and distribution.
Customized production can be customized based on customer drawings/samples and provided systematic service support
Automotive battery soft connection: The core advantage of parallel soft connection between modules
Among modern electric and hybrid vehicles,battery moduleIt is the basic unit for building an efficient power battery system. To achieve higher capacity and more stable current output,Parallel connection between moduleshas become a key technology. We focus on providing high-performanceAutomotive battery soft connectionSolutions, especially soft connection products designed for parallel applications between modules, ensure that your battery system is safe, efficient and reliable.
Why do parallel soft connections are needed between modules?
connected in parallelIt refers to connecting the positive electrodes of multiple battery modules to the positive electrodes, and the negative electrodes to the negative electrodes. This connection can:
- Increase the total capacity of the battery system: After multiple modules are connected in parallel, the power reserve of the entire battery pack will be significantly improved and the cruising range will be extended.
- Improve discharge current capabilities: By parallel connection, the current load can be dispersed, allowing the battery pack to output greater current to meet high power requirements such as vehicle acceleration and climbing.
- Enhance system redundancy and reliability: Even if a certain module has a slight fault, other parallel modules can continue to work, reducing the impact of single point failure on the entire system.
- Optimize temperature management: Parallel connections help distribute current more evenly between different modules, thereby helping to disperse heat and reducing the risk of local overheating.

Features of our parallel soft connection between modules
Our parallel soft connection products between automotive battery modules have been carefully designed and strictly manufactured, and have the following outstanding characteristics:
- Excellent flexibility and vibration resistance: It is laminated with multiple layers of high-purity copper foils and has excellent flexibility. This allows them to effectively absorb the vibration and impact generated during driving of the car and the slight deformation that may occur during the charging and discharging process of the battery module, avoiding the stress concentration and fracture problems that may be caused by traditional hard connections, and greatly extending the connection parts and the service life of the battery module.
- Ultra-low resistance and efficient conduction: Select high-quality electrolytic copper and use advanced welding or pressure welding processes to ensure extremely low resistance at the connection points. This not only reduces energy loss and improves the charging and discharging efficiency of the battery, but also effectively reduces heating at the connection parts and improves system safety.
- high current carrying capacity: Designed for the high-current charging and discharging needs of electric vehicles, our soft connection products can stably carry high-ampere current to ensure smooth and strong power output.
- Excellent heat dissipation performance: The excellent thermal conductivity of the copper itself, coupled with the flexible design, helps increase the heat dissipation area, further reduces the temperature rise at the connection points, and ensures that the battery operates in the optimal temperature range.
- Strong corrosion resistance and environmental adaptability: The surface can be subjected to anti-corrosion treatments such as tin plating and nickel plating as needed to maintain stable electrical properties in complex environments such as humidity, high temperature or chemicals.
- customized solutions: We provide a variety of size, shapes, hole locations and terminal handling methods, which can be highly customized according to your specific battery module structure and connection needs, perfectly fitting your design.
