What Are The Characteristics Of The Copper Busbars Used On Electric Vehicle Power Battery Packs

The power battery is the source of power for new energy electric vehicles and an important system for the entire vehicle. This is also an important symbol that distinguishes electric vehicles from other traditional fuel vehicles. The power battery is the heart of new energy vehicles. By monitoring and managing the battery's status in real-time, the power battery can effectively improve its service life and safety, ensuring the safe and stable operation of electric vehicles. The charging and endurance issues of electric vehicles have always been a key concern for major manufacturers, which also puts forward high requirements for the connection copper bars between power battery packs and battery pack modules.

The spatial layout of electric vehicle power batteries is relatively complex, consisting of multiple lithium battery packs connected in series. In order to increase the range, electric vehicles are usually composed of a large number of lithium battery combination modules. To adapt to the application environment of power batteries, flexible busbars are usually used to connect the battery modules in series.

Flexible busbar for power batteries, also known as laminated busbar, composite busbar, copper busbar flexible connection, and so on. Flexible busbar is a soft conductive device for new energy power batteries. The copper bar soft connection adopts a special process treatment, which overlays multi-layer flat thin copper sheet conductors for corona prevention, and then uses extrusion molding to wrap the insulation layer on the outer layer. This flexible structural design has good elasticity and softness, which can prevent the switch or busbar from breaking due to thermal expansion and contraction. The entire assembly process is also more flexible and convenient.
