Compact battery packs typically use hard copper busbars as conductors, and their insulation is usually wrapped in heat shrink sleeves or molded or immersed in molds. However, the internal environment of electric vehicles is complex and there is also a lot of vibration, and soft copper busbars are usually used as conductive connectors. Soft copper busbars are made by laminating multiple layers of copper foil, which have good flexibility and can provide various bending and folding shapes to meet the required space. In order to meet various temperature and insulation requirements, insulation is usually replaced. Another type is FlatWire, also known as flat wire copper busbars, which are mainly used for new energy vehicle battery units and electrical components. They are suitable for charging batteries in automobiles and are also a solution to replace traditional bus connections between the main power supply and distribution equipment.
At present, most electric vehicle power system batteries are designed using soft copper busbars, which not only have good conductivity but also are more convenient to install. The power battery is an important component of electric vehicles, and can be said to be the "heart", so its reliability and range are both important. In order to break through the limitations of traditional automotive conductive cables, flexible copper busbars are a more suitable solution. Layered soft copper busbars are a new type of battery conductive accessory mainly used for conducting new energy vehicle power batteries. They not only have good conductivity, but also dissipate heat quickly.
YIPU Metal’s laminated soft copper busbar uses T2 red copper, which has good conductivity. The use of multi-layer copper foil lamination processing can not only increase the conductive flow rate, but also withstand the high input and output of the power battery. The laminated soft copper busbar uses a professional welding machine to complete the structure of the middle soft state and both ends hard state. The welding area can be easily stamped and punched to facilitate the series connection of lock screws between batteries. However, the parts without welding in the middle can be covered with insulation sleeves, which have good flexibility and can be easily bent, effectively offsetting the stress generated during car driving.
