Factors in designing power battery pack connectors

The power battery is an important component of new energy vehicles and is crucial for the safety and performance of the vehicle. Lithium ion batteries are combined in series and parallel to form battery modules, and the connecting piece plays an important role in connecting the batteries together. A good connection process can ensure a stable connection between the connecting pieces, improving the structural strength and stability of the entire battery module.

To ensure the safety and performance of power batteries, the design and selection of connecting pieces need to consider multiple factors. For example, the material of the connecting piece should have good conductivity and corrosion resistance to ensure smooth transmission of current and long-term reliability. In addition, the structural design of the connecting piece also needs to consider factors such as temperature changes, vibration, and stress to ensure the stability and reliability of the connection.

In addition, there may be differences among power battery manufacturers in choosing the thickness of the connecting plate, as the thickness of the connecting plate can affect the weight of the required materials and the overall weight of the power battery module. Reducing the thickness of the connecting piece is one way to achieve lightweight design of power battery modules.
