Abstract
An apparatus and method of welding a tab of a battery pack, is disclosed. Batteries are placed on a main body of a jig, having a wing unit attached to the jig. A tab is attached to the wing unit, the wing unit being rotatably connected to the main body of the jig. The method includes attaching the tab to a wing unit of the jig by using an adhesive member, welding the terminals of the batteries to the tab, and separating the wing unit from the tab.
Claims16
A method of welding a tab of a battery pack, the method comprising:
- placing a plurality of batteries on a main body of a jig;
- attaching the tab to a wing unit which is connected to the main body of the jig, the tab having electrical conductivity and being formed of a non-magnetic material, wherein the tab adheres to the wing unit via an adhesive member disposed between the tab and the wing unit;
- contacting the tab attached to the wing unit of the jig to one or more terminals of the batteries by moving the wing unit into a position proximate the batteries;
- welding the tab to at least one of the terminals of each of the plurality of the batteries;
- and
- separating the wing unit from the tab, wherein the adhesive member remains adhered to the tab.

A battery pack control system comprising:
- a battery pack comprising:
- a plurality of batteries,
- a tab having a first and second surface, the first surface welded to at least a part of one or more terminals of the plurality of batteries, and
- a magnetic body attached to the second surface of the tab;
- a magnetic sensing unit configured to generate a sensing signal upon sensing the magnetic body of the battery pack;
- and
- a control unit that is electrically connected to the tab of the battery pack configured to control charging or discharging of the battery pack in response to the sensing signal received from the magnetic sensing unit.
