Surface mount bus bars are mainly used in new energy vehicle battery packs, playing a role in current transmission, distribution, and connection, ensuring efficient and stable transmission of electrical energy within the battery module.  ‌

core functionality

Current transmission: Collecting and transmitting electrical energy from individual batteries or battery modules, reducing the number of cable connections, and solving high-density layout problems.  ‌

Current distribution: evenly distribute the total current to each individual battery to avoid local overload and extend battery life.  ‌‌

Structural connection: Connected to the battery module through welding or bolt fixation to enhance overall mechanical strength and resist vibration and impact.  ‌‌

Materials and Design

Conductor material: Pure copper (T2) or brass (H62) is commonly used to balance conductivity and mechanical strength.  ‌‌

Insulation layer: using materials such as epoxy resin and polyester film to ensure dielectric properties and breakdown voltage.  ‌‌

Heat dissipation optimization: When designing, thermal conductivity should be considered to prevent temperature rise during charging and discharging processes.  ‌‌

Application field

In addition to new energy vehicles, it is also widely used in high reliability scenarios such as aviation power systems, communication base stations, and military equipment.  ‌
