Incorrectly connecting battery pack copper busbars can pose serious safety hazards and operational risks. Battery packs, especially in high-power applications like electric vehicles and energy storage systems, require proper connections to ensure safe and efficient operation. Here are some potential safety hazards that can arise from incorrect battery pack copper bar connections:

When traditional copper busbars are connected in battery packs, it is common for the wiring joints of the copper busbars to dissipate heat too slowly, resulting in line aging. This type of copper busbar has poor heat resistance. Usually, the heat dissipation effect of copper busbars is poor, and the heat dissipation is easily retained within itself, which affects the transmission efficiency of copper busbars. And in the face of some collision situations, the copper busbars cannot protect the wiring terminals. The process of immersing the copper busbars in plastic is adopted to solve this problem.

The power battery pack is a place for storing and releasing electrical energy, mainly composed of multiple power battery modules connected in series, and each module is composed of multiple individual power batteries connected in parallel to form a module. The connections between individual power batteries include square, cylindrical, flexible, and so on. The main connection scheme between battery modules is the busbar or high-voltage battery connection harness.

Energy storage systems often involve multiple types of energy, equipment, and substances, and are complex energy systems that change over time. Energy storage systems are mainly used to overcome the temporal and local differences between energy supply and demand. The energy storage battery pack is an important component of the energy storage system, and stable and reliable conductive connections are required between the energy storage batteries. Nowadays, the most common conductive connection component is powder coated hard copper busbars.
