The power batteries of new energy vehicles need to rely on copper bars to connect with each other to form a high-voltage circuit. Copper bars are made of flexible or hard copper bars that can be bent. They are responsible for connecting various battery modules in the battery pack in series and playing a conductive role, with the characteristics of high current and high voltage loads.
The copper bar of the new energy vehicle battery pack is a conductive connection solution for the power battery pack. The vibration generated during the driving process of a car can have an impact on the battery module, and the flexible structure of the copper bar design can reduce the vibration generated during the driving process of the car and the impact on the battery electrode. In order to ensure good connection stability, high requirements are also put forward for the quality of the copper bar.
As an internal connection component and conductive main busbar of the battery pack, the copper bars can be bent according to the required image during the internal structural design process of the power battery pack, achieving layout adaptation. In order to match the image of the top and assembly surface of the product, the copper bars can change the insulation material according to the environmental conditions of use, and there is no need for additional connection products.
The power battery pack generally requires a compact structural design, and the heat generated by the battery itself accumulates towards the middle. As the operating time increases, the heat dissipation of the power battery also increases. The copper bar connection can timely dissipate the heat in the battery pack, which is an important measure to ensure the normal temperature of the battery module. The copper bar also has a heat dissipation function.
Power battery packs have high requirements for current, and general conductive connections cannot carry such a large voltage. Therefore, power battery packs usually require soft connections with copper bars, which play an important role in current transmission and electrical equipment connection throughout the entire circuit.
