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, the application of new energy soft copper busbars is becoming increasingly widespread and has been vigorously promoted in the market. The copper busbar welding technology is also constantly improving, and the common welding processes now are argon arc welding and polymer diffusion welding. The difference between these two processes is now shared by YIPU Metal, a copper busbar manufacturer.

The battery pack is one of the key components of new energy vehicles, which can monitor the temperature of the battery pack in real-time. The system will take necessary measures to control it, ensuring that the battery temperature is within a safe and suitable range. Its safety has always been a focus of market attention. Copper busbars, as an internal connection solution for battery packs suitable for industry development, are increasingly widely used and favored by the market.

Copper busbars are an important component of new energy vehicles, serving as electrical conductors. The main raw material is red copper, which is prone to heat generation. Generally, it is necessary to design copper busbars with a larger cross-sectional area. However, this not only increases the size of the design, but also requires more investment in costs.
