Connecting Sheets
Connecting sheets are key conductive connectors that join cells into a complete circuit for module charge and discharge.
Connecting sheets are essential conductive connectors in battery modules. Their main role is to interconnect cell terminals into a complete circuit so the module can charge and discharge.
They must provide stable, reliable connections under current changes and temperature stress during operation, with enough elasticity and fatigue resistance to withstand mechanical stress over long use without fracture or looseness.
Specifications
Common materials: copper, aluminum, nickel, and other high-conductivity metals. Nickel offers good corrosion resistance and strength for stable-performance scenarios. Plating/coating is often applied to improve conductivity and reduce contact resistance.
Advantages
- High conductivity for fast, efficient current transfer
- Mechanical strength and toughness against vibration and thermal stress
- Strong corrosion resistance via material and surface treatment
- Stable electrical performance in complex module environments
- Supports lightweight designs that reduce module mass
Applications
- Electric vehicles 鈥?interconnect cells into complete circuits
- Energy storage systems 鈥?reliable current paths to external equipment
- Portable electronics 鈥?notebooks, tablets, and other devices requiring compact reliable interconnects
