New energy vehicles use lithium batteries as power batteries, which are composed of different battery modules, but each battery pack is independent. How can several battery packs be connected? We need a conductive connector that can withstand high voltage and strong current. After continuous market testing, the copper busbar soft connection has good conductivity and insulation performance, making it an ideal choice for conductive connection of power battery packs.
The soft copper busbar is formed by molecular diffusion welding of thin copper foil, which is punched using stamping equipment and covered with insulating sleeves. This type of soft copper busbar can withstand large currents.
When processing soft copper busbars, the first use of copper foil raw materials should comply with relevant standards, and secondly, deburring treatment should be carried out to eliminate defects such as corrosion, oxidation, oil stains, and cracks that affect their performance. Laminated soft copper bars require high accuracy for threaded holes and installation holes. The copper busbar joint can be directly punched without the need for cable joints, making installation more convenient and fast.
The soft copper busbar is mainly used for the conductive connection of new energy vehicle power battery packs, in addition to flexible connections between transformers, generator sets, and other large conductive equipment.
The insulation layer of the copper busbar is made of high-temperature resistant special toughness PVC material, and the conductor is composed of multi-layer anti-corona T2 red copper. According to different processes, there are extrusion type, immersion type, and heat shrink sleeve type copper bars. Our copper busbar products are easy to bend, flexible to install, and aesthetically pleasing, suitable for electric vehicles and power equipment.
