What Are The Current Welding Processes For Battery Packs Of New Energy Vehicles

[Schneiderman Racquel]

I know a little about the battery pack of new energy vehicles, that is, the battery pack of automobile power. There are many parallel or series battery blocks in it. What the landlord wants to ask is how to fix and weld these battery packs together

there are many kinds of welding processes. The welding methods of each power battery manufacturer are also different

as far as I know, both Ningde times and AVIC lithium battery packs have ultrasonic welding process in use

when selecting the welding process, the asprecisionparts.com/types-of-milling-operation/ following points are mainly considered:

what is welding

welding is also called fusion welding. The welding process is to make the atoms of two workpieces diffuse each other through heating, pressurization, or both, with or without welding materials, forming the processing process and connection mode of metallurgical combination. Welding is widely used in both metal and non-metal applications

classification of welding

Application of welding

in addition to being used in the factory, welding can also be carried out in a variety of environments, such as field, underwater and space. No matter where, welding may bring danger to the operator, so appropriate protective measures must be taken during welding. Possible injuries caused by welding to human body include burns, electric shock, visual damage, inhalation of toxic gases, excessive ultraviolet radiation, etc

I hope I can help you

welding of aluminum alloy battery box

At present, brazing furnace or high-frequency induction brazing are used. The two welding processes are not perfect at the current stage and need a lot of application and verification. Relatively speaking, the current way of high-frequency induction brazing is better, because the equipment investment cost is low, more flexible, and the later use cost is also very high. However, the universality is not good, and the requirements for product structure are relatively high. The equipment procurement cost and use cost of brazing furnace are very high, and it is difficult to support if the batch is not enough

to sum up, induction brazing technology may be a preferable welding method at this stage
