The copper busbar plays a crucial role in electric vehicle (EV) power battery packs by facilitating the efficient distribution of electrical power among the individual cells or modules within the pack. It acts as a conductor, connecting the positive and negative terminals of the battery cells or modules to create a series or parallel arrangement, depending on the desired voltage and current characteristics of the battery pack.

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.
