The main naming method of battery pack is: according to the external dimensions of the battery: thickness, width and length.

Examples:
For example, the square lithium ion 602035 model refers to the physical part of the battery cell, which is 20mm thick, 60mm wide and 35mm long;

For example, the cylindrical 18650 model refers to the electric core with a diameter of 18mm and a length of 65mm;

1. Connection process
With the continuous development of pack process, the connection mode is continuously improved - from the original wire tin welding process to nickel sheet tin welding process, from nickel sheet tin welding process to nickel sheet spot welding (resistance welding) process, and from nickel sheet spot welding (resistance welding) process to laser spot welding process;


2. Wire soldering process

Connect the electric core and protective plate through wire tin welding, and then assemble the rubber shell. The equipment and tools used are mainly the tin welding table.
