である。The spot welding between the intermediate tab 4a and the connection electrode of the protection circuit board 5 is, for example, as shown in FIG. 4 (a), for example, two rectangular shapes arranged closely on the protection circuit board 5. An intermediate member 9c of the same type as the intermediate tab 4a is previously soldered to the connection electrode 8 including the lands 8a and 8b, and the intermediate tab 4a is superposed on the lands 8a and 8b via the intermediate member 9c. Then, spot welding electrodes 9a and 9b are brought into contact with each other from above the intermediate tab 4a to perform spot welding between the intermediate tab 4a and the intermediate member 9c. The same applies to spot welding of the intermediate tab 4b.

減を阻害している。However, when performing the above spot welding, generally, the spot welding electrode 9 is used.
Since the a and 9b are positioned directly above the lands 8a and 8b, the solder located immediately below the spot welding electrodes 9a and 9b may be heated and melted and scattered. Therefore, after the spot welding, it becomes necessary for an operator to visually remove the scattered solder using a loupe, which hinders the reduction of the manufacturing cost of the battery pack.

In the provided battery pack, the electrode tab on the protection circuit board, or a connection electrode to which an intermediate tab connected to the electrode tab is spot-welded,
There is provided a battery pack having an electrode pattern shape including lands formed in a region excluding a portion where a welding electrode for spot welding abuts via the tab.

FIG. 2 is a diagram showing a schematic configuration of the intermediate tab 4a and the connection electrode 18 of the protection circuit board 5, and FIG. 2 (a) shows the intermediate tab 4a on the intermediate member 9c for welding which is previously connected to the connection electrode 18. The state where it abuts is shown. The connection electrode 18 is provided on the surface of the protection circuit board 5 and is composed of four lands 18a to 18d formed by dividing a generally rectangular shape by a central axis in two directions. Note that 18 e in FIG. 2A is a printed wiring that connects the connection electrode 18 to a circuit portion (not shown) of the protection circuit board 5.

This is performed by bringing the tips of the spot welding electrodes 9a and 9b into contact with each other. The pair of spot welding electrodes 9a and 9b are shown in FIG.
As shown in (a) to (c), the land 18a and the land 1
8c is located above the gap 18f, and the spot welding electrode 9b is located above the gap 18g between the lands 18b and 18d. In other words, the lands 18a to 18d of the connection electrode 18 are provided so as not to be located immediately below the portions where the spot welding electrodes 9a and 9b contact. The intermediate member 9c is made of the same material as the intermediate tab 4a to be welded, and is made of a nickel plate here. The thickness is, for example, 0.15 mm.

る。When the spot welding electrodes 9a and 9b are driven in this state to perform spot welding of the intermediate tab 4a to the intermediate member 9c, the welding current does not flow directly above the lands 18a to 18d, so that the welding heat is generated. ~ 18d is hard to reach. As a result, there is no problem that the solder connecting the intermediate member 9c is melted and scattered on the lands 18a to 18d. The same applies to spot welding of the intermediate tab 4b to the protection circuit board 5. However, in this case, aluminum is used as the intermediate member 9c.

If the thickness is increased from 0.3 mm to 0.3 mm, the heat capacity of the intermediate members 9a and 9b increases, so that heating of the solder is further prevented,
It has been confirmed by experiments by the inventor that the scattering of solder is further reduced. In addition, 10a-1 in FIG.
0e is a land portion for soldering the lead wires 11a to 11e for connecting the battery pack to an external load (not shown),
Reference numeral 12 is a connector for connecting the lead wires 11a to 11e to the external load, and all of them are connected to the protection circuit board 5 prior to the connection between the protection circuit board 5 and the intermediate tabs 4a and 4b (electrode tabs). .

ができる。When the protection circuit board 5 is connected to the intermediate tabs 4a and 4b as described above, solder balls will not be generated due to the scattering of solder. Therefore, the generation of solder balls can be visually observed with a loupe or the like as in the conventional case. The next battery pack assembling work can be performed without performing the inspection and solder ball removal work. That is, without performing the inspection / removal work of the solder balls, the intermediate tabs 4a and 4b connected to the protection circuit board 5 are spot-welded to the electrode tabs 3a and 3b, respectively, and the protection circuit board 5 is attached to the battery body 1. You can move on to the work of connecting. At this time, as shown in FIG. 1 (a), by aligning the L-shaped bottom sides of the intermediate tabs 4a and 4b with the electrode tabs 3a and 3b, the protection circuit board is protected from the battery body 1. The mounting position of 5 can be set.
