Features
The battery ultrasonic metal welding processes used in battery modules mainly include laser welding, ultrasonic welding and resistance welding. Among them, laser welding with industrial robots is gradually becoming the main force of the automated module production line.
The welding process has high efficiency and is easy to realize automatic production. After continuously improving the welding process and limiting the thermal influence in the forming process, the application in actual production is also increasing.
FAQ
Q: Where is ultrasonic crimping better than terminal crimping?
A: Ultrasonic crimping has a much lower voltage drop than terminal crimping under the same conditions, so it has much better electrical conductivity and signal transmission performance than terminal crimping. There are at least the following three advantages.
First, it solves the voids formed by terminal crimping, and improves the electrical conductivity and the stability of the entire electrical system.
Secondly, it reduces the heat accumulation caused by contact resistance, and prevents the hidden quality hazards of the local temperature rise of the wiring harness and the wiring harness burnt.
Third, it prevents the wires in the wiring harness from being affected by external moisture, dust, oil and gas and other undesirable factors, causing the copper wires to rust and oxidize, thereby causing a decrease in electrical conductivity and distortion of signal transmission.
Q: Why is ultrasonic welding battery pack so popular in the new energy automobile industry?
A: My country's new energy vehicles mainly include pure electric vehicles (BE V), hybrid electric vehicles (HEV), fuel cell vehicles (FCEV), etc. The battery pack is the core energy source of new energy vehicles and provides driving power for the entire vehicle. It mainly constitutes the main body of the battery pack through the shell as the carrier of the battery module, and the welding quality of the battery pack plays a vital role in ensuring safe operation and protection.
